Sir......I know this thread is old, but I need my 2014 Z51 torque converter and the Chevy dealer says it takes 16 hrs at over $125 an hour to change it....I find that to be totally redicilous to make me think that the man is going to stand under my car for 16 hrs....no lunch, no smokes, no bullshitting around! ?that is hwy robbery....he says he has to take out the trans to change the converter....I can't picture that is necessary...he says he has to take out my American Racing Long tube headers......do you have any knowledge of where I can find something in writing to take down there to show that they should not have to pull my trans to change the converter? And are you familiar with that stupid cost and amount of hrs to do the job? Appreciate any info from you on this....Thank you...

It took them 2 days to do mine. The rear suspension, transmission, exhaust, torq tube all had to be removed... Guess that's not what you wanted to hear.

they are correct. Most of the lower rear of the car had to come off including the tranny.

Maybe if it's their first TC change out. Otherwise I dont believe it would take a professional mechanic with a lift 16 hours to perform this job if he is already familiar with it.

Just my .02. Sucks your PT warranty it gone

My C7 had the same problem (among many others) took it to the dealer and the tranny guy showed me a service bulletin that talked about this problem and blamed it on a bad torque converter stator. I took the car in and for some reason they replaced the whole transmission under warranty. problem went away and 10,000 miles later its still good.

The TT Change in my C7 takes one day here in Germany

8.30 in the morning I arrived at the dealer, 5.30 in the evening they finished the work.

Congrats. What GM dealers are still operating in Europe? I thought GM sold Opel and Vauxhall to PSA. I have lots of fond memories of my years in Germany.

We have a 2016 Z51 coupe and developed the dreaded shudder at 11,100 miles (more or less). Took it to my nearby dealer yesterday (01/10/2019). They were able to confirm the problem. The service bulletin for this still calls for the triple flush as the first attempt to remedy the problem. And it appears to have worked -- so far. I am to drive the car for 200 miles and then take it back in to be reassessed.

BUT, the reason I wanted to post this was that the service agent mentioned when I first came in that he thought there was a "brand new fix" related to the stator. But it's not an approved policy as yet. :-(

I'll get back here after another 197 miles and let you know what's up then. :-)

Same story here. I dropped my 16 Z51 off a couple days ago after putting 200 miles on from a flush. Now they say they have done another flush and to drive it 200 more miles. Personally Im tiring of GM's game pretty quickly. It's like running over rumble strips, its not gonna fix it. Other than waste my time dropping it off. Was strongly considering a Z06 upgrade but im certain this is my last GM car.

I had my TC changed on my 2015, along with a 3x flush, two years ago and the dealer showed 13 hours on the invoice. It was a warranty job.

In the German Corvette Forum somebody wrote yesterday - GM has terminated all contracts with GM dealers/vendors in Germany / whole EU

I hope, they will care for the warranty in future - my car has another 2 years warranty.

Default Torgue converter

[color=left=#000000]I have experienced most of what you have listed, the tech verified my complaint and found bulletin # 16NA175. The torgue converter oil was changed. Changing the oil is not a simple procedure, they have to drop the exhaust system to perform the oil change. As of right now every thing seems to be much better. However after reading about these problems I do not think that this is going to be a permanent solution.
I bought this 2016 Stingray from a small dealer, the service rep said that this is the first Vette that they have done this repair.[/color]

Default Torque converter problems

OK I've been following this tour converter problem for sometime now because I have a 2016 C7 automatic. The general reading of all of the large number of these threats of this thread it appears you wash it out three times and problem goes away well I'm sorry but I don't think that's really the answer it's a temporary fix but it's not the answer imho. The prblem is the change from V4 to V8. This seems to cause "metal shavings" in the transmission fluid.

Then the 3x flush washes them mostly out of tranny But not all of them!

When you spin a bearing do you drop the pan. Dump the oil on the pan. Pull the head, drive old piston out replace the bearing? NOT ON MY CAR YOU'RE NOT!!!

They shudder in “M” mode also. The Camaro forum had a post regarding a class action lawsuit being started by a law firm in Palm Beach Gardens, Fl.

I think the real answer is to trash the V4 mode and just keep the damn thing in V8 mode all the time. It seems simpler to just reflash the ECM than deal with all these TC and transmission replacements. I don't think GM is going to do that though.
