6T40 Solenoid - What they don't want you to know! Plus trying out our new service pit!

- If you build it they will come! Lol Days after completing our service pit we got a transmission failure on our GMC Terrain. See how our pit worked. We found out why all the reviews for the 6t40 6t45 solenoids are terrible. Should you just replace your tcm or tecm? Should you just take it to a transmission shop?

3 trans shops told 3 different stories why my 08 Sienna needs a complete rebuild @ $3800. to $5000.00 So I bought a scan tool & 1 utube video later and 1 bad solenoid my van has driving perfect 4 years now. No such thing as a honest shop !
Glad it worked out!
Facts
I rebuilt my 6T45 in my Diesel Terrain. Was pretty easy. The solenoids aren't your problem it's most likely your pistons. Also adding in the Sonnax shift kit and drum saver does wonders for this transmission. I highly recommend getting the "Hyper Blue" brand pistons which are a little more expensive but much tougher than the OEM ones. 15k miles later I had to pull the trans again because the torque converter went (Should have done it while apart....) but I cracked open the trans just to see how it was doing and everything was perfect AND! My trans fluid was not burnt and black like this trans is famous for. P.S To anyone attempting to rebuild this trans, DO NOT try and replace the rectangular seal on the transmission TCU. You WILL break it. It's not possible to change and I don't know why they include it in the seal kit. Soon as you pop it off you destroy these hair like wires that are connected to the PCB board. It will be a $400 dollar mistake....
@@CelataForCongress sounds like you really gained some knowledge on this build! Thanks for sharing!
Thank you for the advice and information
@@robertquitugua4454 everyones situation won't be the same but it's something to consider.
X frame is still coming! Having a case of "life happens". Adulting sux but have to have transportation for the day job.
Wow , thank you soo much for your information, am about to buy and do a 2013 Nissan Pathfinder, but am buying the valve body with all the solenoid on it , from eBay .
I hope it’s not used , they said it’s new. Lol
@@robertovargas1823 maybe a completely different setup for Nissan. Buying the full assembly probably would have been fine for me on ebay. But the oem mfg doesn't even offer individual solenoids for mine.
Pit looks very handy!
I am enjoying the fruits of my labor. While also doing more labor. Lol
Thank you very much for the advice will be using it thank you thank you thank you brother
Hopefully it helps you get to your solution sooner.
I gotta try this fix before a 4k used or 5k new transmission replacement...
If its over 150k miles its a symptom not the cause. All you can do is clean don't let them sucker you with used solenoids. The actual NEW tecm is about 700 and will take about 200 to get it programmed.
Sinse you can't clean the filter all the aluminum shavings may ruin your new parts. The fully rebuilt transmission cost me 3200 out the door at my local transmission shop.
You probably have a broke 3-5-R wavy plate... which ate up the aluminum drum. Mines severely worn but hasn't broke yet. Also, anyone with HP Tuners MPVI adapter can program (marry realy) a different TCM to the ECM.
They make a drum saver kit for that. The waved plate no longer has internal splines. It now sits inside a thick steel with the splines on the steel now engage with the 456 drum.
Blessings and thanks
Those solenoids are not interchangeable in most cases. Match part numbers. There's different flow rates calibrated for each sol.
Did yoi ever get the solution to this?
Says at the end you have to buy the whole tcm module all the individual solenoids are used they don't sell new ones. I took my transmissions in to be rebuilt and got a new tcm.
The Ford model has 2 pins holding each sol. In... not clips.
I have a transmission shop and I hate this new shit
@@expertguy101 why can't they let you change the filter easily!!! That's the point of it.
Probably the 2-3 band
Nice try. This unit doesn't have a band.
nice clip but..today,s trans shops dont even fix this particular trans..they just replace the whole thing..I know I do it !!!..
They rebuilt my trans.
They look used because they test them before shipping to ensure that they work
False fact. They are used. Come in plastic bags with wear rings on the rubber. They only sell these as a unit with the tcm. They wouldn't have wear rings for a test run they are from years of compression being installed.
I gotta agree with ThinkBuild. They are used. Just consider the source.
lol, bs
Dodge coil
What about dodge coil?
Bottom line go to a dealer bye the shift solenoid
Best advice go to dealer will sell 1 single shift solenoid install it problems solved
@@AffordableAsphaltstriping they only sell as a complete tecm assembly for this style transmission because they want you to pay to program sync it to the ecm. I checked with the dealer. This is how it is.
Location shift solenoids 2006 Chevy HHR 3.5
Don't think so..
The worst gearbox
They definitely made it non serviceable.... have to divorce the engine to change the filter. Thanks for watching.
They told a friend that he need it a new transmission and it was goont to cost 7000 but a oil filter for 7 dollars and is fix they try to get 7000 for 7 dollars aint that a b and im not a mecanic but thanks to you tube he gave me the car for free because he didint wanted to pay the money so i just change that and i have a nice and beautiful honda 😂😂😂😂
@@JuaritozAngeles you have to separate the engine from the transmission and drop the whole front frame just to get to this ones filter. Go figure. If this had lower miles other fixes may have been tried. But at 200000 miles and all the shavings I would have just ruined the new parts. I spent about 120 to give it a try. Wasn't willing to waste 800 on the next step. Glad yours worked out awesome story!
That's a gen.1 valve body. Has pressure switches . Tried to buy just 1 shift solenoid on one i did last week. WIT sells them new as a set, 7 total for around 550. Bucks.
On the solenoid on mine i removed them and saw that there was like a sludge on the top part where there is a cavity.I put it under a high power microscope i have for smd repair and found that there are steel particles in solenoid where shaft is.I suspect its binding the solenoid from smooth operation.I placed a high power magnet near the top and the oil would move like filings definitely the permanent magnet in solenoid is attracting steel filings and there's a buildup.i used high pressure to clean them out but not sure if thats a fix.Funny thing is magnetic plug in transmission has no filings.
@@gerryfowler6128 if these had a filter you could change all if it could be prevented. It feels like the solenoids screens become the filter after that fails.
You have a bright spacious garage work space! My 2000 Chev Malibu(130k miles) has some shifting issue going in and out of 4th gear, only when driving up on medium terrain. The engine RPM surges up and down a few hundred. I changed the fluid/filter, no help. Thanks for showing "The Pit"!
Thanks for the comment! Best of luck on your solution. Don't let the solenoid scammers scam you. They did everything they could to not refund me. They knew they didn't want that used junk back. Luckily ebay enforced the return.
Wow I have the same issue.
@@javiergomez5854 hopefully there was helpful information for you. Basically all the solenoids are a scam.
To let you guys know, if this tranny has fairly clean fluid, the fix for alot of these units is just to use a good scanner and run it through the relearn program. I've fixed several of these trannys by doing that. Same with the Ford units... 6f35

Hello man. I have an Opel/Vauxhall Astra J - P10/2011 - 1.6L A16XER Petrol with 6T40 MH8 Gen. 3 gearbox mounted on it. I decided to replace it with a spare one. The one I've bought looks the same, connects the same, but it's 6T30 MH9 Gen. 3. It was bolted down from the same car, same specs but year 2013. Do you think it will work if i just replace it ? Or chances are that will need relearn of the ecu with the TEHCM. Many thanks !
Ask a transmission shop. Could be allot of variables. Mounting holes, gearing, electronics compatibility. I only know info for this one. Its allot of work to findout the hardway. Thanks for the comment.
@@ThinkBuildTest many thanks
Well as someone who works for Partec for gm the solenoids are not serviceable except as the whole tcm
Exactly all these foreign sounding TH-cam channels are in on the scam!
Try telling me how to fix my Ford F-150 Triton V8 engine transmission the bands are sleeping just a little bit it's a 2001 it goes in the park reverse and neutral perfectly but when I go into drive I have to race the engine up to get it to go into gear do you have a solution to that
Also sounds like a solenoid but maybe the symptom of too much metal shavings causing failure. That age of a vehicle probably has 200+ thousand miles. Everything wears out. Cheap fixes are probably temporary fixes. I don't know this model personally but that is a fare assessment of any 22 year old vehicle. I am going to keep investing in my old vehicle so a transmission rebuild for 3000 was worth it. I will rebuild the engine when it needs it because the interior is still really nice. If I had a ton of issues I would have sold it for parts.
Sounds like your forward clutch drum has issues. You should have the 4R70w tranny in it.
Having same issues finding trim b solenoid for my 2004 Allison Transmission
Sorry to hear that.
Try wit or transtar parts house. They got them.
They don't sell them on Rock Auto?
Let me know if they do.. People act like they are new but they aren't. They are sold as a unit with the tcm.
12:58 " they come from China and not original parts ?" If you go on rock auto and look at the TCU they have one from "GM Genuine " and you zoom in it clearly says "made in China " lol
My Boss stepped back and fell in. It wasn’t good for him. I almost crapped myself
Hes ok 😊
Thats why we are building the elevator floor. It wont be an open hole on the daily.
Your wrong telling these people you can't buy new solenoids without having to buy a tcm. I know trans star, wit. Phoenix, or any reputable transmission parts house carries these new.you may have to buy all 7, but they will be new.
There are other transmissions there are definitely solenoids for. But look online and shop for these on a 2011 terrain 2.4. Read the reviews. Most have someone talking about the rings having wear marks. They are repacking used parts and selling them as new on ebay and amazon. GM only sells the tcm as a whole. 600 dollars. Plus. You should be able to buy them individual but I can't find them. All my local transmission shops sell the full tcm only.
Well,you're asking the wrong people. I just did one and inquired about one particular sol. He told me they only the whole set. They had them NEW, IN STOCK, for 540.00. That parts house was Wit. They do mail order.
Thank you so much for your video
Hopefully it keeps someone from waisting thier time also!
What was the transmission doing prior to removing the solenoids
Getting stuck in shift between 2nd and 3rd. Reving up with no power.
@@ThinkBuildTest my 2013 Cruz is not getting stuck just shifting odd, like a small delay 2-3 gear
@@GM-gj8hs sounds like the beginning. Flush the system soon and you may get some more miles. Just sucks we can't replace the filter of these transmissions. Good luck.
@@GM-gj8hs my Chevy Cruze is doing the same thing. Was just told today it needs a new transmission. I don't think I believe that.
These units will also have a ck. Ball stuck in the plate of the valve body like the old 4l60e always did. It will effect shift slipping.
I know it's a pain but why not buy the new tcm and and swap all the brand new shift solenoids with your programmed tcm that way they are all new and no need for programming and going to tyranny shop for a 3000 fix??
200k miles on car all the shavings that can clog a new 800 dollar module +300 for the tune. If I had less than 100k miles I would probably do just the module swap. These transmissions have no filter you can change so they are particularly dirty. 3000 and now I can go another 200k miles. I may have only got 5k miles and had to rebuild the transmission anyways that would have been a waste.
