A while back I posted some comments about my Chevy Silverado truck transmission. Just thought I would bring you up to date:
SO FAR, they have Greased the yoke............no change, changed the yoke...........no change, removed the pan and checked the valve body......no change, removed the pan again and re-checked the valve body....no change, pumped the transmission.......no change, adjusted the ring-gear and pinion....no change.
GM Field Engineer came and test drove the truck......no change, they have during the past week received 4 more 2013's with same problem.
GM Engineer test drove these and confirmed the problem.
Finally, yesterday, they said it is NOT a yoke problem, It is NOT a slippage problem, it is NOT a rear-end differential problem,......YEP.....as I tried to tell them from the start it is a transmission problem.
They now say that, exactly as I initially told them, the transmission is NOT shifting correctly.....wow.....makes you realize why they have 33 million recalls now.
End result....they now tell me that it is indeed a 2013 transmission problem and GM is working on a solution......and.......will put out a bulletin to that effect.
Stay tuned, I'll keep you up to date on it.
Thanks for all your prior comments.
