Transmission help
My 2007 silverado classic is having a shifting problem. It seems to slip then grab between 1rst and 2nd at low throttle position, 25% to 50%. I noticed that it occurs if I increase the throttle position while the trans is shifting. It does not happen in tow mode or at full throttle. Wondering if anyone else has had this problem, or if anyone knows if this is a Ecm reprogram issue or if it is a internal issue.

I am sorry to hear about your transmission trouble. I have looked through my resources and am not showing any known transmission problems for 2007 Silverado's. If you PM me your VIN number, I can research your vehicle further. I may be able to find additional information.
Have you taken the vehicle in for an inspection yet? How often is this occurring? Is this a recent development?
I look forward to your reply.

Hi Louis, I have not had a GM dealer look at it yet. I am trying to diagnose as much as I can before I bring it in. The problem doesn't occur all the time, but enough to be concerned. The vin# is 2GCEK13Z771154140. It seems like its a delay in shift at lower TP. I have learned to prevent this from happening by letting off during the shift. I take really good care of this truck. I have done two t-techs in 88k. I hope that its nothing serious.
