When I worked for the dealer back in the mid to late 00’s we couldn’t believe how the wave plates were breaking so often considering gm & Ford spent 3/4 of a billion dollars on this transmission. Also the engines had bad problems. We would see brand new engines with timing codes because the head was machined wrong so the cams had too much endplay.
Managed to get a rubber tube stuck in the dipstick canal of our 2008 Aura XR 6T70 so need to pull off the control module to try to get that tube out. I'm guessing some fluid will run out but how much not sure...
Hello David.. Man are you knowledgeable....question, my 6t70 has been making a soft shudder sound at 2 nd to 3rd shift and then goes away completely...barely noticeable. Torque convertor? 2014 SRX4 Cadillac Gordy
I have a 2007 Saturn Aura (3.6l), 6t70. I have an offer from the local Automotive College to rebuild it, if I pull it. I was a mechanic back in the day. Any thoughts on this scheme? The instructor was a GM technician.

What is average cost for this? Do you recommend doing a fluid change/flush? Mine has 80k and I’m positive the fluid has never been changed. I get there’s no way to swap the filter without cracking it open. I’m just trying to get longevity out of it. Thanks 🙏
great video, looking forward to the going back together video. Have you seen one of these stall the engine going from 6 gear to 5 gear shift with tcc unlocking at same time. at about 40mph coast trans shifts down from 6th to 5th tcc goes off but it lugs engine and stalls it leaving you coasting with no power steering. repeatable everytime. the work around for now is manual shift to keep tcc from locking so we can drive it until i can get to repair. everything else working well engine wise. i need to understand the tcc 6th to 5th logic any ideas thanks.
Im at 287000 miles on my 6T75. I've had converter lockup shudder since about 180,000. Multiple drain and fills can only do so much. Now it takes a moment to go into reverse. My question is can these transmissions be removed without the use of a lift?
Hey David I was wondering if you could help me out you having the past I have this application in a 2012 Chevy Impala and when I'm driving in the mountains I get a message on the dash that says put car at idle transmission is hot now should I just flush out the radiator transmission cooler and hook up an external cooler and run it after or just bypass the radiator cooler and go right into an external cooler for the transmission I've read a lot of different posts about it and some say that certain newer transmissions won't operate properly if too cool so what is your opinion on what I should do I'd really appreciate it if you could let me know when you get a chance thank you very much...
So was the filter the problem?also you mentioned that piston will cause nuetral to drive situations. That’s what my wife’s 2009 enclave is doing. I did the wave plates but didn’t change the piston. Maybe I should do that?
@@expressautotransmissiondav4207 got a question for you. Took the out the output speed sensor. It’s got copper end and it spins freely. Is that normal?
I have the exact transmission,in a 2008 Pontiac g6 gxp- 6 speed auto... I had the car serviced...and they flushed my transmission....the very next day,when i was driving it,there was no power...only revved up...i didn't get any lights..etc..or codes?? Seems if i turn it off...restart i can go alittle ways..and it does it again.... Any help would be awesome... Called for a new transmission...and its gonna cost me over 6 Grand...once its all installed.... Way more then what i want to spend..
@@expressautotransmissiondav4207 hi Dave no codes,in fact he rebuild put wave and all the goods, including valveboby and reprogram.works well sometimes.
@@expressautotransmissiondav4207 thanks Dave that was really important that I need to know the answer cuz I have one doing the exact same thing looks just like yours not much wear and tear inside the unit I suspect there was a problem with the converter itself. I'm going to recommend a converter a light kit and that Sonic's kit that you talked about thank you again. Keep the videos coming 😃😃
Yep that's the one and way I do it is with a pipe I machined down that fits inside and has a driver welded on the end. Way I was taught was with a rubber mallet and an aluminum block.
I was wondering if you could help me on my 6 t 70 in my 2012 Impala sometimes when I put it from Park to drive it goes in hard but other times you can't even tell what controls that so I can fix it
First thing I'd like to know is history of repair as well as miles on the vehicle fluid condition and level and verified engine mounts and if there are any codes I need to know them as well.
@@expressautotransmissiondav4207 it's a 2012 Chevy Impala with a 84,000 MI I just put a new transmission filter and new transmission fluid all factory recommended sometimes when I go from Park to drive it goes in hard sometimes it's so smooth like butter you can't even tell but I don't have any codes when I read the fluid level when it's cold and not running it's fine but when it's running the level of the fluid doesn't show on the dipstick
@@expressautotransmissiondav4207 like I said it doesn't do it all the time but I want to get to the culprit before it turns into a problem but when I had the transmission apart I'm inspected the tecum and everything went good
@@expressautotransmissiondav4207 I didn't want to overfill it cuz I put 10 quarts I'm going to put it back together I put a half a quart in the torque converter but I did completely flush and clean out the transmission when I had it apart I hope that's all it is and thank you very much for your quick response I'm most likely going to rebuild the transmission completely which brand of transmission rebuild kit would you recommend for the 6t70 for my 2012 Chevy Impala and thank you so much again for your help I really appreciate it
EDUCATIONAL AND INFORMATIVE
and I greatly appreciate your knowledge and time .....
Thank you I appreciate that a lot.
I dont know what impresses me more. The techs knowhow or the engineering that went into this contraption

@express auto & transmission David lee. is it possible to change the tcm without removing the transmission from the vehicle?
Great video. Only thing I would ask, how do you get the neutral safety switch out?

Where did you go? I haven't seen a video from you for over a year.
Do you see many issues with the gen 2 Tehcm's? On the 6t70 if so what kind of problems?
What is average cost for this? Do you recommend doing a fluid change/flush? Mine has 80k and I’m positive the fluid has never been changed. I get there’s no way to swap the filter without cracking it open. I’m just trying to get longevity out of it.
Thanks 🙏
I recommend 40000 mile intervals
Where can I get a 2GEN 6t75 rebuild kit is for a 2016 gmc acadia?

Absolutely reach out to me this week during business hours and I'll go through it with you.
how do i reach out to you during the week?
Call me at express auto transmission in Baxter springs

Absolutely. When I started this shop I only did them on the floor on stands it's not as fun but it's very very manageable.

What was the cost of this rebuild?
Make a farting song video as your putting the transmission back together
If only this unit wasn't done already
Alot going on inside.
So was the filter the problem?also you mentioned that piston will cause nuetral to drive situations. That’s what my wife’s 2009 enclave is doing. I did the wave plates but didn’t change the piston. Maybe I should do that?
It's a definite must. Also techem replacement is always a good idea
@@expressautotransmissiondav4207 tear it down it again. Thanks I appreciate the info. So you have a place to recommend to buy parts?
I buy a large majority of my parts from transtar.

@@hectormaldonado1091 I'm not sure off the top of my head
We are all having a blast daily....
Too bad you didn't cut open the converter to show the problem. I did not see any failures.
I have the exact transmission,in a 2008 Pontiac g6 gxp- 6 speed auto...
I had the car serviced...and they flushed my transmission....the very next day,when i was driving it,there was no power...only revved up...i didn't get any lights..etc..or codes??

Any help would be awesome...
Called for a new transmission...and its gonna cost me over 6 Grand...once its all installed....
Way more then what i want to spend..
what was the resolution?
Is It 1st gen 6t70 ? Or the model manufactured after 2013 ?
First is before 13
Hi Dave my friend has 6f50,harsh,rev,3rd,5th,he put other valveboby ,works well at times then melfunctions,any ideas.
Possible to have a broken wave plate. Do you have any codes and what's the fluid condition look like
@@expressautotransmissiondav4207 hi Dave no codes,in fact he rebuild put wave and all the goods, including valveboby and reprogram.works well sometimes.
@@robertnunez5036 was it reprogrammed to also what brand of techm was installed
So what was the failure??
This unit had a bad low piston and a broken diaphragm in the converter causing lock up shutter and slipping in low range

Whats the easiest way to install yoke sleeve on 700r4 and is parts #gm 8654063 the right one
Yep that's the one and way I do it is with a pipe I machined down that fits inside and has a driver welded on the end. Way I was taught was with a rubber mallet and an aluminum block.
@@expressautotransmissiondav4207 ok thanks ill find pipe try that i was thinking maybe heat it up but its pop can metal and would melt
