I had a complete transmission rebuild, torque converter replaced, transfer case and new pump installed. Bobby's transmission cannot seem to figure out what is casing this and I am looking for some guidance. When I reach 45-50 mph it can see the front (green) TOD lights flash and then I can hear the front wheel drive engage. In addition to this I have noticed the check engine light turn on. the closest Isuzu dealer is a good 4.5 drive to SLC, UT. Does anyone have any advice???

Possibly a wiring problem when it was all put back together (broken or smashed wire, missing connector, etc)
Have you checked to see if any CEL error codes have been generated?
