My 88 astro with the 700r4 wont shift from 1 to 2 under normal throttle pressure it only shifts to second if i snap the throttle. The transmission fluid is fresh and full. It doesnt smell or looks burnt. I was told it needs a new valve body or a tv cable adjustment. can anyone tell me how to do the adjustment and what should i do next? Thanks for reading
