Tranny Problems
 

Hi I have a 1994 Gmc Jimmy with a 4.3 Vortec.
When i'm taking off from a start the trans doesn't seem to want to shift from first to second gear. If I let off the throttle after accelerating and then tap the gas the trans shifts and is drivable. When it does shift it does not shift into gear hard it shifts with ease. I was wondering if this could be the trans computer or the shift solenoid?

Ttt!!!!
