When they changed the flex plate and the intermediate steering shaft the first time what was the reason you took it in for service?

Took it in for the recall on tailgate supports rusting

I'm pretty sure I'm going to be S.O.L on this one. Maybe I'll do a newer Gen 6.0 motor and 6l80e swap because I'm already screwed

Funny your said that. My wife's car has a known issue fur the same thing and the new part looks different. Here is the link. Also her car has the l76 6.0 and 6l80e. I haven't seen the issue on hers but it was a known issue on the forums.

The reason I ask is. If you didn't take it in for a flex plate or a shaft problem why are they changing it without notifying you. Could be that they put a flex plate and a shaft in another truck and charged it back to yours. Or they might have punched in the wrong VIN. In either case maybe this is the first time for the flex plate problem. In which case wouldn't be out of the norm.

So 80,000 miles is the new norm for flexplate failure? My suburban suggests otherwise with a wimpy 4l60e and 200,000 rather poorly maintained miles lol! Could my truck need a flexplate spacer and not have one hence causeing failure.

By the way, this failure is not just a small one. It's got seven major cracks. I'll try to post a picture

Great pic, I would say it was honestly cracked. As for the previous plate that was supposedly changed at 40K, not buying you would not know until now that is was replaced along with some steering parts. My two cents, parts break, owning vehicles cost, and if there was a known systemic issue with the flex plates it would be all over this page, but there isn't. Buy the new plate, take the 4 hours to change it, and enjoy your Chevrolet as your vehicle is well past the warranty and the "I Care" range for Chevrolet to even offer you an oil change or consider your issue a problem.

I absolutely see your point in saying you don't buy that I didn't know but I really didn't. It was years ago though and back in 2006, even if I did see a flexplate on the repair write up, I would have no idea what a flexplate was. So I probably saw it and just shrugged it off thinking it was normal. My only concern at this point is if I put a new plate in, what will stop it from breaking again?

Maybe this TCI flexplate would fix your problem? http://www.summitracing.com/int/parts/tci-399754/overview/

servantsalesmen · September 3, 2014

I have read that putting in a bigger plate would just pass the issue to the trans. Is that true? I had looked at that plate already and was pretty much sold on it. I'm just holding out to buy parts till I'm done fighting with GM lolololooooololooooooolololol even though I'm going to lose

Man this has turned into a sloppy mess. I really can't understand why I'm having this problem. Maybe my truck accidentally got a corvette motor and truck tranny and flexplate and it can't handle 600 hp! I'm taking the plate to a transmission specialist to see what he can tell me.

You should make sure the plate is not stressed when tourqued between mating surfaces, you may be able to get a donor bell housing to make things easier and will be ablle to feel the binding better if thats the case. The best thing would be to check the mating sufaces with a straight edge if even possible. I would take the advice and look for an after market part from a 4X4 shop.

Best of luck!!

servantsalesmen · September 12, 2014

I just got a tci plate. Rated for 8000 rpm and machined from high strength steel. Looking at both mating surfaces and with a level on them, they appear straight. Local mechanic said he changed a number or these plates in the past year and he thinks it's just because gm uses crappy stamped steel on them.

The link to the plate I purchased is somewhere in this thread if you care to look at it.

Thanks!
