Torque Converter problem

[sdouglas2004]

I hope this info is helpful to others. My 2009 Sierra SLE (4x4 crew cab, 5.3L) started shuddering a few weeks ago when it entered 3rd and 4th gear. It was especially pronounced when going uphill or on hard acceleration. I suspected the torque converter based on other posting I've seen here on the board. I called the GMC customer service center (the truck has 47K miles and is still under warranty) and was very pleased with how they handled my case. The customer service rep (Joan) took all my info and had me on hold while she set up a diagnostic appointment with the closest dealership. I took it in and it turns out the torque converter needs to be replaced. Joan called me back right after I spoke to the dealer and told me everything was covered by warranty, how long it would take and when she would call again to follow up. I'm almost 50 years old and looking back on all the vehicles I've owned, I can't think of any car dealership that has gone to that level of effort for their customers- especially if a warranty claim was involved. My advice to others who are having mechanical problems on a vehicle is to start with GMC customer service...my experience has, so far, been excellent.

 

I'd also like to say thanks to all the other folks who take the time to post to this board...I can't begin to list all the helpful info, tips and tricks I've discovered just by reading through the forums.
