- In this video, i go through the 6T40 valvebody, also show check ball locations(Gen 1) Sorry for the short video, shop is packed and im off to work, trying to keep up.
what do You use to grinding valve body(my english not good enough,sorry if wrong terms use).
and whad do you do with checkballs???)))
Valentin Ivanov I use a fine stone to flat sand. The check balls seal off circuits so the oil gets directed correctly. The check balls have to be in there.
like Knife Sharpener!??!?))))
when you use fine stone?
only when there is gasket between? right!&
?
yes like that, not only when theres a gasket, every valvebody i flat sand, sometimes they tend to warp
Hi, I have a 2011 Cruze with a bad gen 1 6t40, no reverse, 3rd, or 5th. Is it possible to make a gen 2 6t40 from a 2013 cruze work in this car? Possible to swap my gen 1 valve body and tcm/solenoid unit into the gen 2 transmission? thanks
No, a lot of changes on the Gen2
Hi, I have an 6t40 generation 3, no forward gear, no error codes, only reverse working. Oil is dark brown but has normal oil smell. Can it be the valve body or tcm ?
I dont know if you monitor this channel but I'm doing a gen 3 6t45 and i have the rebuild kit im wondering if im supposed to scrape the gasket meterial off the separator plate because the kit came with just the paper gasket with no metal backing. I almost dont even want to replace it because scraping that gasket off just seems like a bad idea
If the gasket is good leave it, it's bonded to the plate
Wonderful video Gary.
Thank you
@@GaryFerraro does sonnax drum saver kit really help for worn hub in 6T40 ?
@@Dillipkiit I have never used it yet, but if that 3-5/Rev wave plate goes bad, that drum saver should work, i have heard good things, i think it's a little pricey thoiugh
@@GaryFerraro Thank you. But how much mile one can expect from rebuild transmission?
Hello Gary , my 2011Buick LaCrosse xl 2.4 transmission 3-5 n reverse went out . I had the tcm replaced with solenoids . Now it won’t take the reprogram. Do I need to change out the valve body like you did in the video? Any response is extremely helpful thanks
update?
Hi brother , plzzzzz
don't forget show video for reprogramming step by step
Thank you Gary great video
MOHAAD AHMED ok I will try next one I get. I just did about 5 of these I should get more
hello from Turkey. I am a chevrolet user with passion I have been using chevrolet cruze 1.6 for 8 years. and I love so much. When the engine is hot, it makes it very difficult to move back and forth when the vehicle stops. no problems when the engine is cold. what could be the reason. no fault code.
Sounds like the filter is clogging up
vehicle after making the road. When the engine stops hot, take the park back or forward, after 30 seconds the vehicle moves, difficult to get up,
No more problems after shifting to 2nd gear@@GaryFerraro
After attempting to remove the MLPS and move car, it was still just revving and going nowhere. I tried cleaning the valve body and starting car again, was getting code for no transmission communication, tried pulling the MLPS again and battery to try resetting and now car wont even turn over. Did I somehow screw up the TCM/ECM? I think I'm gonna chock this one up as a loss and get rid of it.
Something must have happened to the MLP, if it shows its not in neutral or park, the car wont start
Hello I am from turkey. I have a vehicle with a 6t40 transmission. my problem is, there is a knock when passing from 2 to 3. We adapt, then it knocks as it goes from 3 to 4. This situation changes with each adaptation. We renewed the solenoid valve body, but the part in the video did not change. only the solenoids have been changed. But the problem still exists. Could the part in the video cause such a problem? thanks a lot.
are there any codes present? is this after overhaul?
@@GaryFerraro There was no code before and after the repair. We changed the solenoid valves (with tcm unit) due to knocking, but the problem still persists.
@@gokhangul4908 you could have internal problem, when you say knocking do you mean trans is slipping?
@@GaryFerraro yes, I mean knocking, transmission slippage. That is, the gear changes, but there is a space in the gear shift and we feel a knock. In addition, we have never been able to complete the adaptation. When we want to adapt, it interrupts the adaptation.
@@gokhangul4908 If you did valvebody and solenoids and it did not fix, you have internal issue maybe bad clutch pack. How is reverse?
Man I know this is a old video but can I swap valve body from a gen1 into a gen 2 6t40 and use the gen1 tcm?
I have the same question, did you figure this out?
I swapped in 2 transmissions now. First was bad from junk yard. This one is in and I swapped in the valve body and tcm. And I have no codes but no reverse right now. And haven’t taken for a drive but I’m assuming it is because of the gen 1 valve body in gen 2 trans. I replace all my shift solenoids with tested ones and still the same.
I read on a equinox forum someone doing it and it worked fine
The only info I found was on the Cruze forum with a senior member stating he has heard its possible but never seen it successfully done. I am considering digging into my trans and seeing if it was the 3-5-R wave plate that came apart as it sounds like this is the most common failure. It appears sonnax makes a 3-5-R drum saver kit with a modified wave plate to fix it if the damages aren't too severe.
Mine is a 2011 Cruze (gen 1 6t40) and I have access to a 2013 Cruze trans (gen 2 6t40) Or my brother has a 2011 malibu transmission if I can talk him out of it, I'm assuming that one would be a gen 1.
Thanks for posting, I am about to take my first crack at an automatic trans and the 6T40 videos are great insight. 2 questions on this one: I believe you called it the Techm(?) It looked like the TCM and solenoid assembly. Is this a standard replacement item on the 6T40 or what dictates replace or reuse? I am also curious about the reprograming statement, does the dealer have to do this or is it something that I can do with a scanner. I have found this assembly at my local vendor, about $360, would rather not replace if not necessary, but do not want to go back for repeat of work either.
I always replace them as part of rebuild procedure, they do give problems. The one at your local vendor, who's is the maker of the Tehcm(tcm) is it OE or Doorman?
This one is a Delco Pro, surprisingly, it is cheaper than the Dorman.
Still a little concerned about reprogramming capabilities (not sure if my scanner is up to this, still looking). Is replacing the solenoids a reasonable option as opposed to whole assembly?
@@evansg7124 I wouldn't use the dorman. I really never replaced just the solenoids, not sure how much they are. Does that Delco pro come programmed?
@@GaryFerraro It does not say in description, I do not think I have bought an ECM in the last 10 years that did not require programming. One of those things that the frequency of needing has made me buy the interface to do this.
Please help me to programming my TCM 6T40 for Chevrolet Malibu 2010
My 6t40 has a very erratic shift into 5th gear only, both up and down. Valve body or solenoid assy? Thanks!
Any codes present?
Man thanks for the quick reply! We are a used car lot and took it on trade. I never drove it long enough to throw code? I did see that the shift timing would correlate with the weird shifts. I pulled the solenoid body off and all the solenoid screens look good etc. Feels like a valve body issue but my trans parts house has told me their solenoid kit rebuild or something like that? It has probably been 5 years since I've been into a trans kinda of fun.....well if I fix it.
@@cletusharbuckle The rebuild kit is for the pressure switches. How is 3rd and reverse. there is a 3-5/reverse drum, usually if something is wrong with 5th there may be issues with 3rd and reverse
Replaced tehcm, 4qt came out 4 went back in, can drive for ten minutes until warm then I have nothing at all no gears just act like its in neuter all, every now and again you can feel it slip but will go right back to nothing. Turn the car off and back on works perfect for a minute or two then nothing again. Throwing no codes, fixed the original solenoid codes with new tehcm then this started. Any thoughts
Your filter is clogging up.
Trans will have to come out, something is coming apart and clogging the filter
Gary Ferraro not even a spec a metal in two fluid changes since new tehcm, I'm assuming it's all in the filter but also hoping for a cheap option. For a rebuild kit where do you recommend getting one, confident in doing the job just want to make sure I get a kit that includes everything filter and all the sensors etc and will reuse my new tehcm. Since the tehcm is already programmed I shouldn't need to worry bout that when I'm done right. Can I get parts thru you some how so you can benefit from giving me great info?
Where are you located? Once the TCM is programmed , it will be ok.

hey gary first time really trying to fig out whats going on with trans 2010 malibu if i reset codes it will go into gear and take of then 25 to 50 feet code pops up car goes into neutral
ive not ran the codes yet just bought the car could that be the tcm
Would like to know the code number
@@GaryFerraro heck ya brother would greatly appreciate it very much
@@russellmckay1655 There is a place you could get it scanned
@@GaryFerraro I'm prob gonna do it today I have a snap on solus my friend has the new zeus if there is something specific to look for being the Tcm I just bought it from him so I've never scanned it myself to see but will today do you know what code is for tcm bad
@@russellmckay1655 Just scan the TCM and ECM to start, lets see what codes are present
Do you replace TECM every time, or can I reuse mine if it was clean?
If it's clean give it a shot, what was the problem with the trans?
@@GaryFerraro 3-5/reverse cushion plate and the snap ring was broken, they must have shut it down quickly as there were no metal shavings up by the tecm or filter. It did damage the input planet and sun gear. when I cleaned the valve body saw no shaving and also no shaving at tecm screen. Thanks again Garry
@@oldschool9746 If everything stayed confined to the rear of the trans you may be ok. How many miles?
