WHEN AUTO GEARBOX GETS WARM, IT ONLY ENGAGES 1ST GEAR AND DOES NOT WANT TO MOVE IN ANY OTHER GEAR.

1997 Ford Ranchero • 244,000 miles

When cold operates all gears. As gearbox warms up, it only engages 1st gear so have to drive very slowly, This is a reconditioned gearbox put in at 200,000kms

The most likely causes for the shifting issue is as follows; Blown fuse to the PCM controller
Faulty vehicle speed sensor (VSS)
Shorted second gear control solenoid
Faulty transmission controller (PCM)
