Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / February 2005Rough downshift after fluid/filter change
2003 Dodge Grand Caravan, 3.3L engine, 30K miles On Saturday I changed the transmission fluid and filter on our van. Relatively straightforward job. Used Mopar ATF+4 fluid and Mopar filter. Ever since, the downshift from OD to 3 has been fairly rough - more like a bump than a smooth downshift. It was noticeable before, but now it really gets your attention. All other shifts - up and down - are smooth. Is this normal? Would the new fluid properties cause a change like this? BTW, I only changed the fluid that drained from the pan.

Disconnect the battery for at least 5 minutes, reconnect, then do the fast learn procedure described under "Retraining your Chrysler Transmission" at http://www.allpar.com/fix/trans.html DS Do you have proper fluid level? Filter insatlled correctly? Larry >> 2003 Dodge Grand Caravan, 3.3L engine, 30K miles On Saturday I changed >> the transmission fluid and filter on our van.

The filter was fairly easy - no screws holding it in, just two plastic inserts that snapped into holes on the underside of the transmission. When removing the old filter, I noticed that the old o-ring didn't come out, so I removed it by hand. The new filter had its o-ring intact. I'll try the "retraining" procedure tonight.
