1994 Chevrolet Astro

Transmission problem
1994 Chevy Astro 6 cyl Two Wheel Drive Automatic

I have an 1994 astro van. Problems begain at first the tranny would not shift gears on its own. I had to manualy shift gears by hand. Drove it for about 3 months like that. One day I was backing out of my driveway and it quit pulling all together. Would not go in any gear at all. Thanks for your help.

If the fluid is full and clean, it is most likely a problem with the valve body or the trans just needs rebuilt.
