Just replaced the transmission and torque converter in a 2007 h3 hummer. Everything bolted up nice; however the vehicle will not shift at 35 mph to next gear. Is there something that needs to be reset in the electronics?

No, what was the reason you replaced it?

Was the check engine light on?

Rebuilt unit or used?

The check engine light is on now.
I changed all fluids and flushed the whole system out
(Transmission fluid and Transfer case fluid)
It goes into all gears fine reverse ect.
