  1. Disconnect the battery to wipe the system memory clean (of course you will lose your radio presets and clock, but that's worth if it fixes the problem).
  2. Reconnect the battery [after a decent interval] and start the engine.
  3. Drive trying to maintain a constant medium throttle position as it accelerates up though all four gears (watch your tachometer). If the tranny is working correctly, you should only have to go to 45-50 mph. Do this from a standing start 15 - 20 times. You'll need a couple of miles of lightly travelled two lane.
  4. With the van below 25 mph, do 5 - 8 wide open throttle kickdowns to
1st from 2nd or 3rd. let the van run in 2nd or 3rd for at least five seconds between kickdowns and remember to kick it down from below 25. With the van above 25, do 5 - 8 part to wide open throttle kickdowns to either 2nd or 3rd from 4th. Again let the van run for at least 5 seconds in 4th between kickdowns. Kicking down from 45 or 50 mph should work.
