Fix Harsh shifting Chrysler

If you change the transmission fluid on a Chrysler product and don’t use the correct fluid, I can guarantee that you’re going to have shifting problems. The correct fluid for Dodge Caravans and most Jeeps is now ATF+4. If you’ve used any other fluid, drain it and refill with ATF+4. Sometimes you can get hard shifts even with ATF+4. Before you start thinking teardown and rebuild, get it to a shop and have them perform a “Quick Learn” procedure. That clears all the accumulator data and lets the computer relearn all the accumulator fill times and clutch apply information. If it still misbehaves after that, then you’ll have to do further diagnosis
