I have a problem when my pick up is cold like 0 degree weather cold it likes to stall when I shift in to drive or reverse or when coming to a stop light and its still not warmed up. I it never does it when it's cold. It never did this till I changed the tyranny fluid a couple months ago. I and recently I was having shifting problems when the trains was cold but that was due to my tyranny fluid being low. I know about the problem with the pan seal. I did remove the seal that was in there but I'm unsure if I got the new seal pressed in there good enough.

My question is could that pan seal be my problem? Or could it be somthing else? I am not getting any engine codes or trains codes. When I was having shifting problems when my fluid was low I was getting a TCM failure code and a loss of prime prime code in till the truck and trains warmed up. Do you think I should drop the train oil again and look at that seal or do you guys think it could be something else i have a 1400 mile trip coming up next week so I want to rule out any problems before that.

The truck will only do it when it sits outside in the cold for a few hours it won't do it after it's been sitting in the garage any advise is appreciated.
