issue Transmissions Issues/Problems

14SLTZ71 · October 28, 2014

I actually printed that and brought it to the dealer, it , so they told me applies to Mexican made transmissions, not mine made in Toledo. No codes= no problems.

Thanks for your suggestion.

Your truck must be a DoubleCab.

Yes my dealer checked my vin to locate where the tranny was made. SO they told me.....

Your truck must be a DoubleCab.

Does that make a difference? It is a double cab.

99% of CrewCabs are built in Mexico.

Double and Regular Cabs are built in Indiana.

Edit: of course just because that PI doesn't apply to your particular truck doesn't mean your transmission doesn't have internal issues.

Dealer just called me to say their shop Forman drove the truck around and found zero issues with the transmission. I guess Iam not surprised. Anyway will head over there this evening so we can test drive it together.

Nothing like paying 50+k and having problems that dealer doesn't want to address.

What are you gonna do? Give me specifics , do you have more pull then the service manager ?

End of day , you learn lessons and this will be my last gm product. Just too much bs from y'all.

There is an obvious issue with my transmission, and the only response I get when I bring it in is that there are no codes when they hook up the computer. Does GM not have any mechanics on staff? What happened to the guys who take the care out for a spin and can feel or hear something wrong with the vehicle. I guarantee if I brought my truck to my self employed mechanic he would absolutely notice something off with the transmission. I am about to make my third appointment for my transmission, I am bringing in the copy of document with the service action for my issue, it is for the one guy that actually had his car fixed without any BS. I have researched this issue and found that it pertains to any vehicles built in Mexico based on the vin numbers. Mine matches up perfectly, I'll let you know what the excuse this time is for why they didn't fix it.

The sad part about this is I am not a Ford fan at all, and my company just bought a bunch of Ford trucks for company vehicles, and they shift flawlessly. I hate the interior of it but to not have to deal with a jerk every time i shift into second gear or down from third into second, i am almost willing to deal with it. I have owned Chevy and GM vehicles my whole life, and I figured I would be treated better than this when i had a warranty issue. The plastic on my running board is cracking where i step up to get in the vehicle and I have the bumper to bumper warranty, wonder if they will fix that.

If the running boards were on your truck when you bought it they should fix them.

I am right with you on being pro-GM, but my 2014 Sierra SLT Z71 6.2 L Crew Cab (Built in Mexico 1-2014) is having the same transmission issue. In addition, the excess lash in the differential makes any driving in stop & go traffic an absolute nightmare. The transmission takes on a life of its own and the clunking in the rear when the load changes is enough to want me get rid of an otherwise great truck. My last three vehicles, a 2003 Tahoe Z71, a 2002 Silverado Duramax and a 2008 Sierra SLT Duramax were all flawless. The big test is later today as I get the results from the third time it is in for the same above complaint. I'll report back on the results.

GM now calls that “Torque Management” and they will hand you a copy of a service bulletin that says “working as intended”.

Don’t worry its “learning” your driving style. ~ Sarcasm ~

Does anyone have it accel more than intended? I was just doing a U turn and in the middle it wnet faster for second make a slow smooth turn jerky. It will also do burnouts in the morning. I back up and barrly push the gas to go forward it sometimes spin the tire. Then when I make my turn I go around the corner with a locked diff chewing up the grass. I have a huge drivway and to concrete it would cost this trucks value to do.

i notice sometimes that on first startups the gas pedal is a little more touchy for a few second. And it feels really "fast" but then it sinks back down to normal.

If they were part of the original sale then 3yr/36k coverage. Purchased after sale, then 12mo/12k

Now that I read this, I realize it is only happens when I try to get going right after starting. Never when I start and do anything before putting it in gear.

Maybe my weird overspeed issue is related to PIP5175B. I've noticed some real sloppy slip shifts and when flooring the accelerator at ~ 40 I get a good downshifts but intermittent upshifts that either don't happen (feels like i'm hitting the rev limiter) or it slips like an old TH350 into the right gear.
