MODELS SHIFTING

1997 GMC Other

Transmission problem
1997 Other GMC Models V8 Two Wheel Drive Automatic 4L60-E 169XXX miles

169XXX, The transmission failed to shift from 1st. The fluid and filter was changed (it was badly burnt)
It will shift with the wheels off the ground, but will only shift when you let off the throttle when the wheels are on the ground, then it shifts hard from 1st to 2nd. Again the same thing for 2-3 shift, but have to get it up to high speed to shift then. Then when you let off the throttle it shift to 1st again and you have to go through the whole throttle on-off again to get it to shift to 2nd. There wasn't much clutch/band material in the pan when I changed the fluid/filter, and no metal.
