Can figure out what's wrong. After the car warms up... it doesn't shift into overdrive....The rest of the gears shift fine. The tranny was rebuilt last week, Also intalled were a PI 4400 stall, B&M tranny cooler, and a shift kit. Anyone have that problem?

Have the transmission scanned as the the problem occurs.A faulty 3-2 downshift solenoid can cause a no overdrive concern,assuming all other work was done correctly.

I had the same probelem with my truck. So i took it to the dealership and they said it was a valve that was stuck that wasn't allowing it to go into overdrive. They pulled out the valve body cleaned it and installed a valve and bearings and it was fixed.
