hi I have a 1996 2.2 s10 sometimes when it shifts from 2 to 3 gear it spins out like it is in neutral, let of the gas bang like you droped the clutch on a std shift. it don't do this all the time it shifts normal then some times it shifts but really hard. trans has got about 55000 on a 1300 dollar rebuild. its just this 2 to 3td I am having trouble with. any ideas? done a data log today it spun out when it caught I thought it busted the trans it caught so hard and I was off the gas pedal. finnaly got it to throw a code po 756? changed the a and b shift seleniods fixed it. trans only has 50,000 miles on it sense a total 1300 dollar rebuild that is with me changing the trans.
