I've searched the forum here, but haven't quite found what I am looking for. When my truck sits for a few days, the torque converter drains, and I go no where when I start up. I've read that it is a problem with a check valve spring. Does anyone know of a TSB number from GM to fix this problem? I'd like to have as much info as possible before calling the dealer.


Thanks,


Steve


PS. The truck is an 03 Dmax/Ally.

Very common problem, they should have no problem with it. Check the TSB section, I believe the TSB is posted over there
