WHAT CAN CAUSE THE LOCKOUT NOT TO DISENGAGE?

1999 Dodge Ram • 240,000 miles

I have a 99 Dodge Ram 2500 Diesel 4x4 (240000 mi)with an automatic transmission. The problem I am having is that the 4th gear lockout does not disengage. When I put it in gear it is like trying to move in 4th gear. It stalls a lot. I changed the lockout solenoids and it has not changed. I rerouted the coolant lines to see if that was the problem and it is not. Do you have another suggestion?

Have you had a transmission diagnostic scan done, not all set codes will bring up the check light, the problem does sound electrical, I would start here.

Yes a scan was done and no codes were showing.

I would be thinking that the TTC is stuck on, I would get a trans specialist to check this first hand to confirm the diagnosis.
