Transmission problem
1994 Geo Prizm 4 cyl Front Wheel Drive Automatic
----------------------------------------------------------------
My differential oil seal was leaking, so i replaced it. drove the car around and everything worked beautiful. About 2 hours later I went back to my shop to rotate my tires and once I was finished I decided to go home. As I left my transmission wouldnt shift out of 1st gear. What could be causing this to happen when it has been driving , and shifting like new?

Check to see if it has a throttle valve cable, a cable that attaches to the throttle body cam and goes to the transmission. This increases hydraulic pressure to the transmission as the TB rotates.

The cable could be broke/kinked/out of adjustment.
