#117 of 118 Transmission/Torque Converter Problem
Nov 25, 2009 (10:34 am)
I have a 2006 Silverado 2500 4x4 with a 4.10 rear end and 6.0L engine. This problem is getting worse and worse. The truck shifts fine until I get up to interstate speeds (65-70mph) and then hesitates prior to going into overdrive. It will run 2800 rpm at 70mph on flat land. The only times it will go into overdrive is when just starting up a hill (sometimes). When in OD, it will hold 70mph up a 9% grade at 2400 rpm. As soon as the road levels off or starts down, the rpms will jump back to 2800 and it will no longer be in OD and will not return to OD. My interstate mileage has dropped from 14 to 10 with no load. Any ideas? Torque Converter issue possibly?
On a side note, the computer has been spewing out codes indicating 3 of the 8 cylinders are repeatedly misfiring. Dealer has cleaned the fuel injectors and ran some sort of GM fuel system cleaner through the system, but the problem persists.

Long time no post as these forums are a ghost town since these forums turned into a pro import/anti American vehicle site !
Still have my 07 Chevy 2500 4x4 gmt-900 now with a measly 56k miles.
No issues of any sort and the only maint. has been oil and filter changes, a new set of tires at 35k, brake pads all around and rear rotors along with a tranny service at 50k.
Still workin' it plowing snow in the winter and pulling the boat, camper or toy box in the summer.
Will wait for the 2014s for a new GM truck at this point...........................
