What causes my 1996 4l60e transmission that won't shift without letting off gas?

Answer 1

The first, and easiest, thing to check is the tranny fluid level and condition. If it is too high or too low it can throw off the shift points. Also, the tranny fluids I have always dealt with are a nice light red in color and look for signs of gunk or fragments of metal or other items on the dipstick. If you do see metal fragments on the dipstick that tranny is a basket case and needs some intensive care and work. The first, and easiest, thing to check is the tranny fluid level and condition.
