Pretty sure its normal, mine does it every time until warm, just like you said.Hey,
This has been going on for quite a while, but I've had no other problems with the tranny so I wasn't sure if it was normal or not. For some reason, when my truck is cold and I go onto the highway, OverDrive won't kick in until the truck warms up (the temp gauge moves just barely into the "normal" range). Is this normal or should I be worried? I've checked the tranny fluid level (after 50 mile drive) and it is about 2 mm above the top 'dot'. I don't have any other tranny issues. Any info would be appreciated. Thanks...
