Auto Trans questions
 

I have a 95 12v 4x4 with a auto and shifting from 1st to 2nd it doesn't shift until I let off the throttle and once it shifts into od it will kick in and out what would cause this? Thank you very much

Sounds to me like a throttle position sensor.

That would affect the Trans?

Yes.
