Once put in gear it does not shift to next gear. I have changed the transmission and transfer case three times same reaction. Need your advise!

The power train control module operates both the engine and transmission. I would check to see if the wiring to the transmission is okay. Check all fuses. If they all look good I would suspect the PCM is bad.
