- The AFL valve allows pressure to various clutches in the transmission. When the valve bore wears, it causes pressure loss which causes various shift concerns.
I won't be doing any trans work, but i fix EVERYTHING else on.my buick; but thanks for an EXCELLENT tutorial, i wish all presenters were as thorough. Great job
Thanks
Thank you, Hiram also says ALWAYS superior K098 but he didn't show it done. Now I can see clearly how good it is and will do this. Sonnax requires their reaming jig and tool set, but quit making it so that leaves us in a no answer lurch. This is perfect for the DIY.
Really, sonnax quit making the tools for this?
@@thisisyourtransmission That's what their website says, they suggest we contact suppliers in case they got old stock and of course older shops that have the tools bought way back in the good old days. Not all of them mind you just the valve body jig set up and some of the custom reamers.
Follow up - I'm an idiot, got confused when they dropped Volvo support in one tool line and misunderstood the rest to be the worst news ever. Sorry. Download this pdf and read under item 12 where I panicked.

Thank You, Thank You, Thank You..... My 4t65e channel plate just happened to be sitting on my desk because of a no shift problem when I found your head ache saving video. One shot of air to the AFL valve reveled that it dose not move at all and oil shoots out its back side! WoW who knew? Well you did thank God! Thanks again! You are awesome!

Thanks for taking time to make your great videos, helping my son rebuild his 4t65e on his 2000 Pontiac Grand Prix GT, 1st to 2nd intermittent gear bump when warmed up. a little overwhelming being our 1st automatic transmission rebuild. The car has 205,000 everything looks good, clutch packs are in good shape but we plan to replace frictions any way and put extra steels in packs as needed. I suspect the problem is in valve body as the valve you are talking about here would not move at all and bleeding out back as you show. Just started all this and am going to check and replace everything recommended in valve body.
That valve is in the channel plate.
@@thisisyourtransmission I have a 06 grand prix, Tranny shifts into rev and drive's in 1st but will not go to any other forward gears and rpms jumps up like its in neutral until i slow down enough for it to grab 1st again. could this be AFL valve ? or shift solenoids/Pressure solenoid
@@joeb465 How many miles is on you vehicle, and what size motor is it?
@@thisisyourtransmission 109,000 and it’s a 3.8 liter
@@joeb465 Transmission is going to have to come out of the vehicle , taken apart and repaired. If you remove the transmission pan, you will probably find a piece of broken band lying in the pan.
I finally got around to taking my channel plate off and this was bad. I air checked it to but it was completely stuck closed wouldn’t move at all! Thank you for sharing this video!

The proof is in the pudding!!! Thank you kind Sir!!

This is the best 4t65e video by far! 2 thumbs up. Watched it like 4 times.

I just had my transmission the one you're talking about completely rebuilt because 3rd gear and drive went out. And when I pulled it out of the lot every day for the past 3 weeks sometimes more so than others the car will jerk back and forth from 3rd to drive when I put it in drive. So when I put the car in drive and I just take my time it will jerk back and forth from 3rd to drive. So I've been driving it in third gear most of the time cuz it feels better but it's still slightly jerks in third gear every once in awhile especially like on level roads or going up the hill a little bit. My car has never done this before ever and the car is very well kept up it's the first time pulling out the parking lot of the transmission place it's been doing it for the last 3 weeks. I do have a guarantee cuz they said they completely rebuilt it so I feel that it's the transmission so it'll be going back soon maybe you guys could give me some pointers
If you had it at the transmission shop, then it is the shop that needs the pointers. The shop has to figure the problem out. They need to talk to ATSG, which is a tech company that I use at times. That said, everyone does not rebuild transmissions the same. As a result, it would be hard to tell you what they did not do. They will probably have to take the transmission out and go over their work.
@@thisisyourtransmission wow that's horrible that they got to redo do it or look at it or whatever. I know I was always told if you have to get a rebuilt transmission your car it will probably never run the same. Ever since I pulled it out from there lot from day one, it has been acting up and the car is never ever done that before. And who knows if they'll turn around and say something else is wrong with the car, it's just extremely hard today to get good mechanics, for one they can't get the help nobody really wants to work in this field they're hard to get, and they're just so busy and backed up and people are getting sick left and right from the covid and the respiratory virus and really sucks anymore. Thank you very much I appreciate the advice. Have a good New Year
@@chaseww I know about the lack of help. However, it is the job of the tradesmen to stand by their work. It is part of the job.
Awesome videos. Thanks. What psi are you using for the air testing? Thank you.
I don't know what the psi is. I am just hooked up to the shop air.
Hi, great video, my Lumina 2000 transmission was rebuilt 4 years ago. A few days ago It presented faults, the reverse is applied but slips, the forward shifts applied and also slip, the car barely moves, removing the transmission fuse decreases the slip. Would it be corrected by changing the afl valve? Thank you in advance for your time and dedication.
Can't tell you if the AFL valve will solve this issue that you are having. First, thing to do is scan for codes. Second, is to remove the transmission pan and check for metal and other debris. These are steps that we take in the shop.
@@thisisyourtransmission Thank you!
I have a malibu 2008 with transmission code P1811 MAXIMUM ADAPT AND LONG SHIFT WHAT IS CAUSING THIS PROBLEM??
Thanks for the video. Definitely would use this 1 over the sonnix valve. Got to fix broken forward band. Low budget just that and a few other things. But think I should upgrade to this valve while I’m in there.
Good luck!
What are the differences between the 4t65E and 4t65E-HD. I have the HD but never understood how the HD differs and handles 5.3 engines. Especially why they keep breaking down.
The costs of each repair kit I'm guessing the Superior is cheaper than Sonnax. If it fixes the problem then the Superior is a good product. Thanks for the vid I just started doing trans repairs & overhauls learn a lot.

Hey broo,
When you replace this part, for example my transmission doesn’t have the code or fault but I replaced recently, do I need to flash, re program after?
Now is doing like a little jump between 30 and 40 mph, if I do d-acceleration feel like a have towing a trailer.
Do you have any recommendations?
You do not have to reprogram this transmission. Second, this transmission is not hard to rebuild. However, it has any metal in this transmission, it is probably best to change the whole valve body, because a sticking valve will not shift right.
Hi There. This is my 1ft time watching your video. I have 04 Pontic Bonneville SE 3.8L with 4T65E Transmission. 73,000 miles after getting the battery replacement the scan it and found Code P1811 Code. they test vehicle with scan tool and monitor shift times, Found 3 times 1-2 shift ar .78 shifts time (spec=.65) all others shifts within spec. This is the dealership I used to work at and the Master Tech told me I should do a Trango shift kit SKA4T65E and Maybe AcDelco 4T65E Transmission Solenouoid Kit.. What is your personal thoghts on this...
Thnak you for time and feedback.
You don't need a shift kit. Just rebuild it with an overhaul kit if you want. However, you need to replace the afl valve. I have a video explaining this.
Actually, you are watching it.
I've just installed this. No leaks but the valve doesn't move with air check. Valve moves pretty good. Help . Frustrated.
Hello there...man i wish u was in DC. I got a obd1 93 lumina Z34. 120k miles. All original Canadian Built GM. Im not sure how early 90s gms drive but it takes a little muscle to steer. Its auto 4 drive with 4t60E. My rpms dont bounce up as it should i believe compared to 99-2005 gm cars. I currently drive in 2nd and shift to 3 about 30mph due loss of power it feels. Got it from a garage kept.owner and its so original the tires got major cracks. I changed the modulator leaking heaving trans fluid and still.rpms barely hit 3000 full throttle. Due to age..should i rebuild or find a 4t65 and a 3800. I did not realize how big this 3.4 dohc is and dont want to rebuild it.
This is a 1993. Are you trying to modify this and put in a 4t65 transmission and a different engine?
I just bought this valve to install in my '04 Grand Prix and noticed in the instructions it says programming
with a scanner is required, is it necessary? Also I'm installing the Transgo shift kit KT 4t65e, is it a good idea
to install both? I have code p1811 in history and the car shifts hard about 30% of the time, please do tell.
no
only need to install the valve
Could this be a fix for a 2005 buick lacrosse 4t65e that does nothing when any gear is selected? When I shift from park all the way to low 1 nothing happens no rpm drops, clunks, sound movement anything. The linkage on the transmission does move when moving the gear selector. Car had 135,000 miles Thanks for any advise.
Update: scanned code and there is one for the inside range sensor. Also I found out if the car is on a lift in the air and I put it in drive and give it gas the wheels DO spin. Vehicle on the ground it does not move in drive.
You said the likage on the transmission does not move when gear is selected. This could be a broken shift cable.
I have a 2002 regal LS, vin K, it started having trouble shifting into 2nd when at oper temp but other shifts were normal 2-3,3-4 no slippage anywhere So I changed the 1-2 and 3-4 shift solenoid, filter and fluid . NO change . Now it wont shift into 2nd it will hang between 1st and 2nd if I go fast enough in 1st or go into 2nd for an instance but goes back to 1st or hangs between 1st and 2nd almost instantly If it does shift into 2nd it will shift 2-3.3-4, perfectly, any ideas?
should have an 1811 code. it will not turn on the check engine light
@@thisisyourtransmission had the same issue with my 02 Buick Regal LS. P1811 Maximum Adaptive And Long-Term Shift. I changed out the shifts solenoids (2) and the Pressure Control Solenoid. I also put in a Shift kit for good measures. No more harsh shifts. now Im thinking after watching your video( should Ive also changed out the AFL? I havent driven it much..more of a project car for me. What are you thoughts. it has 214,080 kms. great video by the way. I learnt something new tonight
Great vid thank you ,,I have a 2003 impala ,Engine flares up between 1st and 2nd gear at half throttle ,Light throttle 1 & 2 shifts hard ? Can you point me to the right direction what would cause that ?
Scan it. Look for hidden code 1811
@@thisisyourtransmission What happen was it would not shift out of 1st into second and it gave a p0730 code ,So I changed the filter and fluid ,still would not up shift into 2nd ,Waited a day drove the car again then it shifted but the 1&2 shift is doing what I explained earlier all other gears like 3 & 4 are fine ,,No 1811 code or not yet ,,BTW Thank you for replying back I appreciated
The second clutch drum may have a problem.
can this be changed without removing the channel plate? I'm planning to replace all the solenoids without removing the trans from the car, just dropping it some. not sure if I would be able to do this at the same time?
Yes it can if you drop the motor down far enough. However, you have to determine what to take loose. I do not have a video on doing this yet.
@@thisisyourtransmission after asking that question I rewatched and noticed that the clip you remove has to come out the back side of the channel plate, so I would have to remove the valve body and the chammel plate to be able to service this valve. Still could be done in the car. I'm definitely going to be dropping the subframe and taking the side cover off to replace the solenoids, but I don't think I want to take off the valve body and channel plate too. That's getting too far into it I think. then I gotta worry about check balls and whatever other gaskets there are....
@@dummkompf yep
Mine shudders pretty bad off a stand still. revs up to about 2500 before it shifts into second gear. then barely wants to shift into 4th gear ever. It needs a rebuilt one dropped in
Mines giving off the 1811 code has a delayed shifting when coming from a stand still and previous owner said he replaced the solenoid sensor I believe. Wondering if it’s another sensor problem and what the cost would be to have a mechanic repair it? Any info would be a big help
You need transmission rebuilt or used one installed.
Will this help with a 1810 code
I have a 4T65E that won't shift out of 1st for the first few miles of driving. No CEL on. I thought it was EPC solenoid and have one on order, but now I'm wondering if it's this AFL valve?
This needs to be put on a scantool to see if the computer is commanding the solenoids to shift to second like they should.
I have the same problem but it shifts fine on the lift or basically no load wheels off the ground did you figure yours out?
Thanks for all the information
Gracias
Welcome
Hello to you I have a 2008 Dodge Avenger 2.4L. I just bought the car and every person that has put it on the code reader says i need something called an internal shift solenoid and it a hard shift from 2nd and 3rd shift. they say its inside my transmission. I seen your video for the first time after looking at several other videos and yours seem more accurate to me, when you said their can be false code readings. i need your help. this is my only vehicle and i want to get it fixed. What do you suggest i do?
What is the code?
@@thisisyourtransmission the person that i let check it out said it was U1015
the vehicle needs to be taken to a shop for this type of code. This is a code that requires hands on electrical diagnosis. This is code has nothing to do with an internal shift solenoid.
Thank you very much, so its more of a electrical problem besides the shift solenoid problem. I will go and get this checked out as well. truthfully i wish you where in my area, you know your craft well.
@@kirstiehenderson4193 you are welcome
I don't have the P1811 transmission code or any other check engine code, but I'm fairly certain that my Impala's transmission is failing. Can you rebuild my transmission? 😊😊
Why do you think it is failing?
Do you have to replace a whole new transmission if you have a maximum adapt and long shift
Rebuild, good used transmission will do
All the gears work on my 4T65E HD. Sounds like high pressure fluid squirting. When it warms up. No gears at all. Doesn't even change the engine rpm. Colds down. All the gears are back.
Take the pan off and look in it to see if there is any metal or burnt fluid.
@@thisisyourtransmission I had changed the fluid. Starting to get that smell. More metallic flakes than I expected. But same situation with new filter and fluid.
@@playsportfun3356 what was your problem with your transmission I’m having the same problem
@@corionpumphrey3066 I followed the connections on all the wires made sure there were no shorts. Opened the side up, replaced the wiring harness and all the valves and solinoids. Still, same issue. Turned out to be mechanical after all. I ended up paying $4K to have it rebuilt. I didn't have a clean enough environment to do it myself. Took some investigating to find a good shop. The prices only varied by a few hundred bucks. He did a good job and even added a couple components I was missing like a clip on the air box which was nice.
i bought a 04 impala that was owned by a old lady the car only has 50k miles on it ... im getting this code i cant see something being worn out can some valve be sticking ? the car sat since the end of 2018
Normally, 1811 is a problem on the inside of the transmission. What happens when you drive the vehicle?
Can this alone also cause a pump to whine?
I don't believe so
I have a 01 Bonneville and it slips a lil after driving it for a while and I have code p1811 would this help
1811 needs a rebuild
Thank you teacher..
You are welcome
I have 2006 gxp my transmission ran hot right after rebuild so I add a big rv cooler . After 25000 miles freeway driving I noticed a slight whine at low rpm fluid was changed it was not burned . Suddenly on my way home from work drive and reverse went fluid was ok . I shut of car in park restart I have all gears but sill whines and temp climb to 200 f and I think it slips not driving car . The code is P0. 842 low pressure any help would be good. The car has been driven mostly highway 75 mph and not driven hard .
Pump is bad
@@22koga filter was plugged , changed fluid and filter ok no issues
@@nickking1510 yes the pump not getting fluid would of made the same sound
@@nickking1510 these transmissions also have what’s called a friction drum and they squeal if they are dry
Please don't use ball peen to knock it in!
Good god shut off your air compressor and tell everybody to be quiet in the background when your making a video
My daughter's 2006 g6 suddenly has only 3rd gear. No slipping before and just happened out of nowhere! Could it be the shift solenoids?
Is the check engine light on? What does the computer code say?
Would this prevent shifting to 4th? I have a 00 Oldsmobile intrigue and the transmission works fine from 1-3 but doesn't shift into 4th. It doesn't even try. No slip just no shift like the solenoid isn't working.
you could have a bad 4th clutch hub. The splines could be stripped out
