Couldn't find a shop to "rebuild" replace solenoids etc.. Shops were quoting me $3500 - $4600 to replace transmission. . . . . . THANK YOU SO MUCH FOR SHARING THIS!!!!! :) God bless you.
I know this video is a couple years old but I am so glad you made it. I had all the same symptoms yours had. From a stop, engine would rev but no engagement till there was a clunk and a jerk and off you go. I just finished my solenoid replacement project. It took about 12 hrs. I'll drive it probably 500 miles this week so I'll get a good feel for how it responds. Thank you for posting this video and making content for those of us who are not afraid to get our hands dirty. Spent maybe $150 in parts. Shop probably woulda charged me $1500. Thanks Again!!
@@redwater4778 no it fixed the shuddering from a complete stop. I would press the gas and it would act like it couldn't "catch" the first gear. Hope that helps.
@@southernmost9429 I have a similar problem. But is it affiliated? I release the brake pedal and let her engage on her own then drives fine. If I quickly move to the gas pedal from the brake pedal. Does make a cluck and jerk and drive. BUT also I notice at the stop light, the RPM slightly drops at fine hair move feels wants to choke down.
I am about to do this on my 97 GTP . Got it jacked up and started on and I've been looking for a video for months showing me what all I need to do... So thank you very much as I just happened to come across your video this morning! Very informative! Thank you
Thanks for the video it was very informative. I been working on my friend's 2006 Chevy Impala. Recently the transmission Gave out. But I'm going to swap out the transmission from another Impala my friend purchase. Watching TH-cam tutorial videos I've learned alot about replacing all kinds of parts. Its fun fixing vehicles. 👍
Thank you sir for this great video, you Saved me $2,800 for a Reman. Trans. + Labor. About (3) mths. ago I purchased a 2011 LTZ w/ 118.4 k. (currently @ 120.0 k). After a month driving it; same exact issue with my Transmission (4T65R) has come to the forefront of my Car Issue(s) list. It's very noticeable when street driving; accelerating from a full STOP/or Red Light....transmission engagement delay (btwn 1k - 1.5k RPM) for a few secs. and then a sudden slight jerk forward and the car proceeds forward. No issues on freeway. Now I know the solution, all thanks to your video. Cheers!
Did u end up replacing the solenoid/sensors? If so did that fix it or help or not? I bought an 08 SS with 113k and it was fine but I knew the ATF had never been replaced so I replaced the filter and fluid. Then it started doing that, every so often, from complete stops. never at any other speed, and it started shifting a bit more noticeable into third. I'm assuming the solenoids got dirty/plugged when the old came out and new fluid in.
The 2000 through 2005 Impala with the 3.4 V-6, and 3.8 V-6 are prone to have a clutch inside the transmission that goes out. The problem I experienced on two Impalas was the clutch, and not the solenoids. At 65,000 miles the transmissions on those are junk. When the clutch fails, you feel a grabbing when accelerating from a stop. Then when it goes, the car does not move at all forward, or barely moves.
Started this same project 3 days ago,ordered the same stuff and now playing the waiting game,but hope to get the same results when finished...Great video!!!
@@MichaelsbackyardmarinaIt's a friend's car for his daughter,she gets her license soon,so I'm hoping it at least last her threw high school...A 07 Buick Lucerne with the 3.8 and 4T65E... Side note,Kids drive better cars then we ever did,in high school.🤔😂😂
I know this is an old video but it helped tremendously my impala will jolt every once in a while while driving at low speeds, perfectly fine on the highway and then one day it just stop driving I could drive it for say 30 seconds and then as if it went into neutral no reverse no drive so I did this change the filter fluid and added a Lucas transmission Conditioner whining noise stop shifts perfectly smooth solenoids I got from the junkyard out of a wrecked Impala the harness I just heated up the plugs due to finances but I did get a new gaskets and axle seal inside the pan from AutoZone thank you
Just did this today on my ‘11 LT with 143k on it. Had the same problems you described. Took about 14 hours; did it in one shot (boy am I sore) but your video was a lifesaver. Let’s hope this does the trick.😁
Would be interesting to hear back if it fixed it. Mine has gone 39,000 miles since the repair. I'm about ready to change the fluid again. Thanks for watching
I’ve since put on about a thousand miles going to university and back on the interstate, as well as driving in town and it since hasn’t had any problems with the shifting like before. Ended up replacing the steering rack too since when I was down there I noticed the boots had a good amount of fluid in them, so got that taken care of the next day with some help and got it aligned, but now it drives great for being 11 years old it floats down the Highway.
No reverse sir help you are the greatest transmission GOD I ever seen man you did your thing bro help me I have no reverse all the sudden it go forward on
great video, I got a lead on a 2006 impala with only 120k miles, 1 owner, and in limp mode for 2k. It was a grandma's car, in fantastic shape except for the shifting. I think I might buy it now and get it fixed.
Im about to tackle this job with my boyfriend soon. Our 2012 chevy impala makes a whinning noise, shifts hard out of first gear, has decreased the gas mileage and is starting to have a shifting issue. I hope by changing the solenoids, torque converter pump, tranny fluid, seals (if damaged) and the tranny filter, it'll help the car. Thanks for the informative video, its the only one that I have found that shows you how to get to the transmission from the bottom of the car. 👍
Start cheap!!!! Check all fluids!!!! Change air filter use fuel injector cleaner, check plugs! Replace of bad!! My impala has 264,000 miles drives like a champ!! Had gear slamming abs/vsa lights on replaced all four wheel hubs!! Now all is good!! Wires weren’t frade! I started small ended up being wheel hubs!!!
I own the same Chevy Impala mine's a 2007 LTZ model and it's a great car overall but sometimes the transmission in first gear tents the slip a little. But runs, and drives excellent, even with high mileage!

On average, most acceptable shift time parameters are set at 0.6 seconds. Anything longer will cause the TCM to raise the line pressure, which will cause usually harsh shifts.

@@Michaelsbackyardmarina my impala slips after coming to a stop in overdrive. Its not the clutches because if you shift it manually its solid as a rock. It does this after i stop at about 9 outa 10 times Im not good with computer searches, id appreciate your thoughts. Thanks in advance
I have an 06 chevy impala with V-6 engine. Just spent 3300 dollars for wear and tare stuff. The mechanic told me over the years I've taken good care of this car but stuff will wear out eventually and then you have too kick out some money. It was worth now the car only has 140800 miles on it and still running very good even the gas mileage is very good.
I was watching your video I have a 2011 Impala I having problems with my transmission making some grinding noise when I put it in gear that's when it starts grinding
Don't know if you mentioned it I fast fowarded it through sections, Clean just common grease like chassis grease, bearing grease isn't going to kill your transmission, you can take a little bit of grease smear it on the gasket (particularly that o ring gasket around the output shaft) and let that hold the gasket in place while you hold that thing sideways and put the cover on
Finally got the car done Friday night and it runs great,changed the pressure control switch and solenoid,both shift solenoids,the tcc solenoid,internal speed sensor,and internal wire harness,and for just under $150,it was worth the cost to change everything,then take this apart again.😉😉😉
@@DIY-dv7xj-I had to look for everything on eBay,and the bad thing is that if you order something and it's not the right part,(such as the first wire harness I had ordered)then it becomes a waiting game. Just be careful when ordering parts,make sure that the stuff you order can be returned,especially if your not sure about the part.
Shift problems can return since the solenoids (are magnetic and) attract wear metals from the gears and jam up. I added many neodymium bar and disc magnets on the steel plate on the oil filter right next to the oil pick up opening. I'd add magnets to the oil pan but it is zero clearance when buttoned up. OE magnet in pan is not enough. Easy upgrade and you'll see how well it works next time you change the filter!
I had a 04 impala with 3.8. Trans had problems. I tried the shift kit fix and it worked. Sure it was the solenoid but I did not want to drop engine. I don't know how the shift kit fix fools the solenoid but it did. It shifted so smooth if you did not watch tach you did not know it was shifting. Gave car to my son who put it in a guard rail. Not worth fixing after that. I hope you used quality parts. Great job.
That weird i got 134000 on my 2011 Impala and it runs like new. I keep good care of it. I only thing i had to do is change the oil and brakes plus 2 wheel bearings. I find they are a good winter car with snow tires on. Very comfortable too.
Thank you for the video I have an Impala that is just starting to do this I want to give this a try but I can't find a parts list in your video did I miss it?
Have to say I love Impalas, especially the older ones with the 3800 series 2 (I have an 05 Impala 9c1 with it.) But GM SCREWED UP majorly with this transmission. Again, especially coupling it with the bullet proof 3800 series 2. What good is a bullet proof engine, if the transmission is absolutely junk? Will be doing this fix on both my 05 9c1 AND my 2011 Impala LT. Cheers for the video. I do all my own labor and visual guides like this help immensely! Watch it beginning to end a few times and I can do it on the car the next day. Got my summer project. Might end up saying screw it and buy a new engine for the old cop car while I'm at it. (Yes, the 3800 series 2 is bullet proof, except when the cops abused the hell out of it.)
@@Michaelsbackyardmarina When I eventually drop a new engine in it, I honestly think I'm gonna mod the 3800. As it is a nice platform to mod. Cold air intake, cam, turbo, etc. But, that'll have to wait till "new" engine. No point in modding an engine with 180K+ on the odometer, and the title had 160K which took me 3 years of ownership going 100+ miles a day to exceed. (Severe mileage fraud. Or maybe cops didn't have to report accurate mileage.)
Great video, my wife has a 2010 Impala 3.5 with 240,000. I need to do this trans service. One question I have is did you have to have the front end aligned after changing the trans solenoids and removing the strut?
My 2007 Impala went out and only drove on 2nd and reverse has proper fluid level and I jacked it up and all the gears were responding normally and the tire was moving. Soon as I jack it back down it only reverses but nothing on the other gears.
I saw in the comments that you were having a delayed or abrupt shift from a stop, and possibly other issues. I'm having similar issues, mostly the rev and "slam" into gear while at a stop is my main concern, but only when warm and only sometimes, very odd if you ask me? Question, was yours intermittent also, or everytime you drove it or?? Also I have no codes/dash lamps. Thanks for the detailed video, and any advice!! I'm probably avoiding the obvious but don't want to do that if I don't have to 🤷 Thanks again!
Great video ❤👍💯 !!! I've got a Chevy Impala 2015. It's a 6-speed transmission do you suppose it's the same thing ?? Should I change the transmission fluid every 30,000 miles ?? If you change the transmission fluid will that prevent having to do a rebuild like you did ?? Do the solenoids just go bad from age ??
Great video with great detail, I have a quick question. Would the the speed sensor have anything to do with not shifting into third? I changed all of the solenoids except that one and the speed didn’t come in the kit. Ahh this car is driving me nuts.
Great video . Can someone tell me how y’all knew it was the solenoids ? My 2011 Chevy is having shifting problems once I put it in drive it make a little noise.
I just had mild shifting issues and a little occasional hesitation from a start. Make no mistake the fluid was pink and clean, If your trans fluid is dark and burnt there is a good chance your problem would be much worse.
My 2003 Buick Regal with 125,000 miles with 4t65e started harsh downshifting from real 2 to 1 when slowing down at a moderate pace. It was at first a clank, and now it is muted but at the right slowdown speed you can still hear it a soft clunk, which it never used to do at all. It doesn't slip and it's shift points seem fine. What do you think that might be?
I love my impala for comfort. Huge car & trunk. Fast . Bose speakers ( my favorite ) . But I will say the trans on my 2011 impala has gone out 3 different times . First one was off the factory line , direct from GM that lasted about 40k miles , old lady owned it . It died. Then they put in a new one , that lasted 40k with my sister owning it and taking very good care of it . Then I was on my 3rd trans before 100k miles …….. when I owned it & still do own it. GM claims it was the way I drive the car - that’s why 3 different owners have had 3 different trans , because of the way I specifically drive it ….. yea ok GM . Just admit you made shitty defective parts & still do , certain cars get them other cars are lucky & never have the issue. GM makes billions of $$ . I had to pay $2,500 for a rebuilt trans. So yea love the car HATE GM.
Did you drain the atf from the pan first? I feel like you'd have to but I never see anyone do it or reference it in any of the videos when taking the side case off
My impala slips only when im at a full stop trying to accelerate it jumps once its passings 2 on the rpm should i try to start with a sollienoid fix i do have a transmission leak i need to get to also
I never tried this in theory but something that sounds like it would work as good a safety-pin heat it was a torch and stabbed it through the connector and then clip it to lock is secure if the retaining clip fails I say just do that inside the tranny cuz of the fluid but if I have what retaining clip break on me typically I just put silicone gasket before I put the connector back
Was wondering what code you were getting from your transmission prior to replacing solenoids? I just got my car back from a shop saying it was throwing a 1811 code. Which in their words meant complete replacement of transmission. Cost to replace transmission in a shop $3500-$4600. I am wondering if I can do what you have done to buy some more life for my impala. Same year.also
I had that symptom of the revving from a stop, then slamming into gear...(2006 impala, 3.9l) I added some AT205 on the premise the problem was an aging rubber seal. I also changed the fluid/filter. That seemed to have resolved that very annoying problem. So, now you have me wondering...
Did you ever figure out what the High Rev and slamming into gear was I have an 07 Lucerne doing the same thing which I was getting ready to replace the shift solenoids and pressure sensor wondering if you found out this was the issue or you need a new or remanned transmission
@@patrickmahon5453 from my perspective...I understood the problem to be deep inside the transmission - specifically an aging lip seal that can only be replaced during a rebuild. My understanding is the revving is from fluid escaping passed the input piston seal, then the seal will suddenly 'grap', the fluid will seal and fill the clutch quickly slamming the car into gear. Always from a stop - I found. First, I replaced all my fluid with no luck, but my revving/slamming into gear issue went away a few days after putting a bottle of at205 in the trans...it reconditions seals and is famous for improving rear seal leaks in engines. It's not a classic sealant that makes a mess - it just reconditions rubber parts. I'd try it for $15... (Edit: by the way, I was astonished that it actually worked - that was like 3 years ago)
The issue I have with a 2007 Chevy impala is when I try to put it in gear, reverse are forward it seems like the shift mechanism inside a transmission is broke because it doesn’t do anything. What do you suggest?
It's been over a year now and don't recall all the part numbers. Go to your local Napa store and if the guys inside are any good they can hook you up. My Napa guys here where I live are excellent
The speedometer on my 2009 Impala SS jumps when the car shifts in/out of gear. The transmission was rebuilt in 2018-2019. Is the trans going again, or is it the speed sensor? The check engine light isn’t on.
My 07 was having problems but had solenoids replaced, screen, gasket and worked fine for a bit but slowly started slipping then did nothing.Has proper fluid level and It shifts and I can feel the gears engaging (different jerking feeling in each gear) but won't move just revs
You can get a used transmission for your car, order an entire rebuild kit with all the rings, seals, gaskets, solenoids, etc. Very cheap, maybe 211.00 for all, and honestly, too many unnecessary components. I would watch as many videos as possible, google image the transmission you own, could be a 4t65e or 4t60e or HD, depends on the engine. I have a 3400 (3.4L) V6 4t65e tranny. It's shot, but I knew that when purchasing the car. I got a free transmission, which has to be the exact model as the one you are taking out. You might be able to just take out the current one and rebuilt it, depends on how long the problem has been going on. If you have a check engine light you should be able to get plenty of Troubleshooting codes which can steer you in the right direction. Buy the solenoids, pan, filter, gasket, new upgraded coolant line (in and out), and approximately 16 q of tranny fluid. It's not that bad. I am spending more money on the tools to do the job than the actual parts...ugh.
The valve is stuck that’s why this repair the valve body should be removed and cleaned it’s a steel valve moving inside a aluminum body it builds up a lip and gets metal and clutch material inside and the valve sticks that’s why when you pull these solenoids out the screens are clogged
My impala 9c1 just stopped working while in drive I had to get it home by shifting the gears manually any guessing what's wrong maybe the solenoids or torque converter or clutch plates worn I'm clueless when it comes to transmissions and also how much was it total to get your car back running
@@Michaelsbackyardmarina would u suggest getting a transmission shop to pin point it for me or just chance the solenoids being the problem and do that myself and do u have links to the other parts u didnt buy in the Ebay kit
Where did you order the sensors at for the transmission my car is a 2011 Chevy Impala LT and the transmission fluid where did you get that at and how many miles on your car just wondering man thank you
All the parts I purchased from Amazon all original AC Delco parts. You can get them from Napa as well. Car had 125,000 miles on it when I did the work. It now has 145,000 on it.

What Repairs Will Fix P1811?
Replace pressure control solenoid/EPC solenoid
Replace worn clutches
Replace worn accumulators
Repair valve body
Replace MAF sensor

@@Michaelsbackyardmarina my impala slips after coming to a stop in overdrive. Its not the clutches because if you shift it manually its solid as a rock. It does this after i stop at about 9 outa 10 times
Im not good with computer searches, id appreciate your thoughts. Thanks in advance
Chris I have the same problem. Did you find out the issue ?
I have an 06 chevy impala with V-6 engine. Just spent 3300 dollars for wear and tare stuff. The mechanic told me over the years I've taken good care of this car but stuff will wear out eventually and then you have too kick out some money. It was worth now the car only has 140800 miles on it and still running very good even the gas mileage is very good.
oh yeah, my average mileage is 27mpg
Great video. Should tell in the beginning what the symptoms where and why you changed these parts.
Thanks a lot you saved me money !
Happy to help
Great video and commentary best wishes to you!!👏👏👍😎
1500 miles later still working perfectly.
I was watching your video I have a 2011 Impala I having problems with my transmission making some grinding noise when I put it in gear that's when it starts grinding
This is the best demonstration I’ve ever seened before
much appreciated. Glad you liked it.
@@Michaelsbackyardmarina (((
Don't know if you mentioned it I fast fowarded it through sections, Clean just common grease like chassis grease, bearing grease isn't going to kill your transmission, you can take a little bit of grease smear it on the gasket (particularly that o ring gasket around the output shaft) and let that hold the gasket in place while you hold that thing sideways and put the cover on
Sure could, Thanks for watching
Finally got the car done Friday night and it runs great,changed the pressure control switch and solenoid,both shift solenoids,the tcc solenoid,internal speed sensor,and internal wire harness,and for just under $150,it was worth the cost to change everything,then take this apart again.😉😉😉
Glad it worked out.
Were did u get the other parts that dont come in the Ebay kit and like wire harness and speed sensor ? Thank you
@@DIY-dv7xj-I had to look for everything on eBay,and the bad thing is that if you order something and it's not the right part,(such as the first wire harness I had ordered)then it becomes a waiting game.
Just be careful when ordering parts,make sure that the stuff you order can be returned,especially if your not sure about the part.
very cool video great job...
Thank you very much!
Shift problems can return since the solenoids (are magnetic and) attract wear metals from the gears and jam up. I added many neodymium bar and disc magnets on the steel plate on the oil filter right next to the oil pick up opening. I'd add magnets to the oil pan but it is zero clearance when buttoned up. OE magnet in pan is not enough. Easy upgrade and you'll see how well it works next time you change the filter!
That may be. It's been 16000 miles and it's still going strong
Good job my friend
Thanks for the visit
Thank's a lot for your vidéo 😊
You're welcome 😊
gracias por el video, afortunadamene es exactamente lo mismo para mi impala 2000
Thanks for watching
I had a 04 impala with 3.8. Trans had problems. I tried the shift kit fix and it worked. Sure it was the solenoid but I did not want to drop engine. I don't know how the shift kit fix fools the solenoid but it did. It shifted so smooth if you did not watch tach you did not know it was shifting. Gave car to my son who put it in a guard rail. Not worth fixing after that. I hope you used quality parts. Great job.
I did use all name brand parts. So far so good 15,000 miles later.
Good job dude!!
Thanks!
Nice video thank you
So nice of you
what was part number on the tcc solenoid?
How did you diagnose that the solenoids were the problem?
That weird i got 134000 on my 2011 Impala and it runs like new. I keep good care of it. I only thing i had to do is change the oil and brakes plus 2 wheel bearings. I find they are a good winter car with snow tires on. Very comfortable too.
Thank you for the video I have an Impala that is just starting to do this I want to give this a try but I can't find a parts list in your video did I miss it?
Have to say I love Impalas, especially the older ones with the 3800 series 2 (I have an 05 Impala 9c1 with it.) But GM SCREWED UP majorly with this transmission. Again, especially coupling it with the bullet proof 3800 series 2. What good is a bullet proof engine, if the transmission is absolutely junk?
Will be doing this fix on both my 05 9c1 AND my 2011 Impala LT. Cheers for the video. I do all my own labor and visual guides like this help immensely! Watch it beginning to end a few times and I can do it on the car the next day. Got my summer project. Might end up saying screw it and buy a new engine for the old cop car while I'm at it. (Yes, the 3800 series 2 is bullet proof, except when the cops abused the hell out of it.)
My impala is in my top 3 cars of all time. thanks for watching
@@Michaelsbackyardmarina When I eventually drop a new engine in it, I honestly think I'm gonna mod the 3800. As it is a nice platform to mod. Cold air intake, cam, turbo, etc. But, that'll have to wait till "new" engine. No point in modding an engine with 180K+ on the odometer, and the title had 160K which took me 3 years of ownership going 100+ miles a day to exceed. (Severe mileage fraud. Or maybe cops didn't have to report accurate mileage.)
Like the “how it’s made” tracks
awesome, thanks for watching
Great video, my wife has a 2010 Impala 3.5 with 240,000. I need to do this trans service. One question I have is did you have to have the front end aligned after changing the trans solenoids and removing the strut?
My 2007 Impala went out and only drove on 2nd and reverse has proper fluid level and I jacked it up and all the gears were responding normally and the tire was moving. Soon as I jack it back down it only reverses but nothing on the other gears.
I saw in the comments that you were having a delayed or abrupt shift from a stop, and possibly other issues.
I'm having similar issues, mostly the rev and "slam" into gear while at a stop is my main concern, but only when warm and only sometimes, very odd if you ask me?
Question, was yours intermittent also, or everytime you drove it or?? Also I have no codes/dash lamps.
Thanks for the detailed video, and any advice!!
I'm probably avoiding the obvious but don't want to do that if I don't have to 🤷
Thanks again!
Mine was intermittent. and no codes
Very detailed video and well done explaining in each process
That's a lot work on this job how much is the price to charge something like this
If you are asking me is I will do this for someone else, the answer is I don't do customer work. Thanks for watching
@@Michaelsbackyardmarina i do mobile mechanic that's why I was asking I already know how much I can charge for this local
And u saved$$$$$believe me!I mean u got to change both when u do this job!
Glad it was helpful
Would it be possible to include the part numbers for these? Like the gaskets or a link where you bought?
Why did you put the jack on the oil pain instead of the transmission pan?
Beautiful video! Did you get your parts straight from the dealer? Or do you have a link for them?
I got them from Napa and Amazon. All AC Delco parts is what I used.
@@Michaelsbackyardmarina what parts did u have to order thru amazon that u couldn't find at Napa?
Great video ❤👍💯 !!! I've got a Chevy Impala 2015. It's a 6-speed transmission do you suppose it's the same thing ?? Should I change the transmission fluid every 30,000 miles ?? If you change the transmission fluid will that prevent having to do a rebuild like you did ?? Do the solenoids just go bad from age ??
solenoids just are bad for these transmission. I change mine every 50K miles
Hey I'm having the same problem. Mines a 2013 six speed. Did u find out if the solenoids fixed it ?
Are the solenoids relearn shifts or does the car need to go to a gm dealer for programming
Thank you
Great video with great detail, I have a quick question. Would the the speed sensor have anything to do with not shifting into third? I changed all of the solenoids except that one and the speed didn’t come in the kit. Ahh this car is driving me nuts.
I don't know the answer to that one, I changed them all since I had the cover off.
@@Michaelsbackyardmarina thanks
Awesome video. Do you have to take the oil pan down to drain the trans fluid before doing this repair?
You don't, I didn't, I changed the filter after and fluid after the job was done.
Great video . Can someone tell me how y’all knew it was the solenoids ? My 2011 Chevy is having shifting problems once I put it in drive it make a little noise.
I just had mild shifting issues and a little occasional hesitation from a start. Make no mistake the fluid was pink and clean, If your trans fluid is dark and burnt there is a good chance your problem would be much worse.
My 2003 Buick Regal with 125,000 miles with 4t65e started harsh downshifting from real 2 to 1 when slowing down at a moderate pace. It was at first a clank, and now it is muted but at the right slowdown speed you can still hear it a soft clunk, which it never used to do at all. It doesn't slip and it's shift points seem fine. What do you think that might be?
It could be numerous things. I am not a transmission expert. I just show folks what I was able to do on my machine. Thanks for watching
I love my impala for comfort. Huge car & trunk. Fast . Bose speakers ( my favorite ) . But I will say the trans on my 2011 impala has gone out 3 different times . First one was off the factory line , direct from GM that lasted about 40k miles , old lady owned it . It died. Then they put in a new one , that lasted 40k with my sister owning it and taking very good care of it . Then I was on my 3rd trans before 100k miles …….. when I owned it & still do own it. GM claims it was the way I drive the car - that’s why 3 different owners have had 3 different trans , because of the way I specifically drive it ….. yea ok GM . Just admit you made shitty defective parts & still do , certain cars get them other cars are lucky & never have the issue. GM makes billions of $$ . I had to pay $2,500 for a rebuilt trans. So yea love the car HATE GM.
quite the story. I did this job on mine at 124k and now it's at 147k and going strong.
Mines is out in the garage right now. Tbh I'm thinking of junking it...more than once is too much for me...kudos to you ..I'd never get a GM again
Thank you so much for the video, make more👍🏾👍🏾💯
Did you drain the atf from the pan first? I feel like you'd have to but I never see anyone do it or reference it in any of the videos when taking the side case off
drained it after I was done with the side cover work. Thanks for watching
My impala slips only when im at a full stop trying to accelerate it jumps once its passings 2 on the rpm should i try to start with a sollienoid fix i do have a transmission leak i need to get to also
Is there anyway you can post the link too where you bought the kit?
I never tried this in theory but something that sounds like it would work as good a safety-pin heat it was a torch and stabbed it through the connector and then clip it to lock is secure if the retaining clip fails I say just do that inside the tranny cuz of the fluid but if I have what retaining clip break on me typically I just put silicone gasket before I put the connector back
thanks for sharing.
Do you have part numbers for the harness and sensors ?
Thanks alot!
I don't. I would get in touch with your local NAPA store and they can hook you up with all you need.
hi, i wondering if this parts number apply to 2008 impala ss ?
Now if all cars were that clean to work on...
Was wondering what code you were getting from your transmission prior to replacing solenoids? I just got my car back from a shop saying it was throwing a 1811 code. Which in their words meant complete replacement of transmission. Cost to replace transmission in a shop $3500-$4600. I am wondering if I can do what you have done to buy some more life for my impala. Same year.also
No codes at all, thanks for watching
I had that symptom of the revving from a stop, then slamming into gear...(2006 impala, 3.9l)
I added some AT205 on the premise the problem was an aging rubber seal. I also changed the fluid/filter. That seemed to have resolved that very annoying problem.
So, now you have me wondering...
I now have 10,000 miles on the fix and it is still working perfectly
Did you ever figure out what the High Rev and slamming into gear was I have an 07 Lucerne doing the same thing which I was getting ready to replace the shift solenoids and pressure sensor wondering if you found out this was the issue or you need a new or remanned transmission
@@patrickmahon5453 from my perspective...I understood the problem to be deep inside the transmission - specifically an aging lip seal that can only be replaced during a rebuild. My understanding is the revving is from fluid escaping passed the input piston seal, then the seal will suddenly 'grap', the fluid will seal and fill the clutch quickly slamming the car into gear. Always from a stop - I found.
First, I replaced all my fluid with no luck, but my revving/slamming into gear issue went away a few days after putting a bottle of at205 in the trans...it reconditions seals and is famous for improving rear seal leaks in engines.
It's not a classic sealant that makes a mess - it just reconditions rubber parts. I'd try it for $15...
(Edit: by the way, I was astonished that it actually worked - that was like 3 years ago)
Can this be done on 2012 impala LTZ?
The issue I have with a 2007 Chevy impala is when I try to put it in gear, reverse are forward it seems like the shift mechanism inside a transmission is broke because it doesn’t do anything. What do you suggest?
I haven't had that problem so I don't really know what to tell you. Thanks for watching
i like your presentation very good i ham traing to lacate my speed sensor for my MHP were will i faind it i have a 2012 chevy impala LTZ 3.6
You can do it.
one question? What was your issues to make you change the soleniods? I Have no Drive But have the low gears and reverse
poor shifting and not going into gear from a stop or dropping into gear kinda hard from a stop
Same issue, car drives as long as you drive it like a manual , throw it in neutral when coming to a stop
Thank you for the video helps . Do you happen to have a link to the parts .
Sorry I do not.
i have a p2714 code for pressure solenoid d but idk what "d" is. is it the epc 1-2 2-3 etc?
Not sure what you are asking. You may have already googled the code for the answer. That's my only suggestion
I don't have reverse please help what do I do change selenoid or what
Did ya replace the Pressure Control Solenoid? They're on all the time and cause shift problems when they become jammed up or erratic!
I replaced them all
Was it going in forward or reverse before I'm having problems with Mines not moving at all and I want to know will this help it
mine was driving and shifting but has some hesitation from a stop and some not so sure shifting issues.
what are all the part numbers from all the solenoids you replaced? excellent video by the way. I feel better about tanking on this project.
It's been over a year now and don't recall all the part numbers. Go to your local Napa store and if the guys inside are any good they can hook you up. My Napa guys here where I live are excellent
Would this process be the same for an 07 impala SS with the 5.3?
if it has the same transmission, I think it would be close
@RMDCreations I'm curious, how much transmission fluid has to be replaced?
8 quarts for mine
Is there a certain tourque the 4 star bolts on bottom need to be tourque down too?
There should be but I don't recall what it is.
getting ready to do the same ,what is kit u ordered on amazon ,saw a kit had 5 selonoids
I ordered each piece by the part number as I removed them from the car. There may be a 5 piece kit. I replaced with all AC Delco stuff.
The speedometer on my 2009 Impala SS jumps when the car shifts in/out of gear. The transmission was rebuilt in 2018-2019. Is the trans going again, or is it the speed sensor? The check engine light isn’t on.
I have no idea on that one. Thanks for watching
It’s the lifter motor in the cluster for the speedometer it’s the motor that moves the needle
My 07 Chevy impala reverse went out but going forward has no problems…any ideas how to fix the no reverse?
Non at all. thanks for watching
My 07 was having problems but had solenoids replaced, screen, gasket and worked fine for a bit but slowly started slipping then did nothing.Has proper fluid level and It shifts and I can feel the gears engaging (different jerking feeling in each gear) but won't move just revs
Yikes, sounds like the trans may have been a bit too far gone.
@@Michaelsbackyardmarina 😔
You can get a used transmission for your car, order an entire rebuild kit with all the rings, seals, gaskets, solenoids, etc. Very cheap, maybe 211.00 for all, and honestly, too many unnecessary components. I would watch as many videos as possible, google image the transmission you own, could be a 4t65e or 4t60e or HD, depends on the engine. I have a 3400 (3.4L) V6 4t65e tranny. It's shot, but I knew that when purchasing the car. I got a free transmission, which has to be the exact model as the one you are taking out. You might be able to just take out the current one and rebuilt it, depends on how long the problem has been going on. If you have a check engine light you should be able to get plenty of Troubleshooting codes which can steer you in the right direction. Buy the solenoids, pan, filter, gasket, new upgraded coolant line (in and out), and approximately 16 q of tranny fluid. It's not that bad. I am spending more money on the tools to do the job than the actual parts...ugh.
Probably the torque converter and/or chain drive is shot, take the cover off the tranny like in this vid and you'll see the problem
The valve is stuck that’s why this repair the valve body should be removed and cleaned it’s a steel valve moving inside a aluminum body it builds up a lip and gets metal and clutch material inside and the valve sticks that’s why when you pull these solenoids out the screens are clogged
Did your car stutter really bad during hard acceleration once it was warmed up?
nope, just did a little stall at take off from stop occasionally.
Can you give the entire part numbers having trouble finding them on amazon
My impala 9c1 just stopped working while in drive I had to get it home by shifting the gears manually any guessing what's wrong maybe the solenoids or torque converter or clutch plates worn I'm clueless when it comes to transmissions and also how much was it total to get your car back running
$350 in parts and I did all the labor myself. Can't say what I did would work for every transmission issue
@@Michaelsbackyardmarina would u suggest getting a transmission shop to pin point it for me or just chance the solenoids being the problem and do that myself and do u have links to the other parts u didnt buy in the Ebay kit
Where did you order the sensors at for the transmission my car is a 2011 Chevy Impala LT and the transmission fluid where did you get that at and how many miles on your car just wondering man thank you
All the parts I purchased from Amazon all original AC Delco parts. You can get them from Napa as well. Car had 125,000 miles on it when I did the work. It now has 145,000 on it.
Can you put a link for in the description down below the TH-cam
The shift code everyone who doesn't have a scanner that can scan the tcm is P1811
