I have a 03 trailblazer EXT 4.2 l-6. Transmission worked good until I removed motor and transmission to install a new motor. After installing new motor and reinstalling the transmission I pulled out. I refilled with new fluid. it won't shift past second gear. Any ideas what it could be?

Codes? CEL on? Does it just stay in second?
Sorry I'm just now responding I've been working. When I first crank it and start driving it shift fine after it warms up it starts slipping out of third gear. Haven't had a chance to check codes yet but I will do today since I am off work
