I get the feeling that they tried to put too much technology into this tranny. I just want to be able to step on the gas and have the car move accordingly.
All said, I'm not a fan of this transmission. The Caravan was better.
Do yourself a favor and find an open road area and pull the F60 fuse in the fusebox on the passenger side under the hood. Leave it out 30 minutes. Reinstall and do the following:
1. Drive at light to medium throttle (30-40% torque. Let it shift uninterupted through 8th at 50+ mph. Stay under 2k rpm.
2. Throttle off and paddle downshift 8th to 7th, wait til rpm drop below 1200, downshift to 6th and wait to 1200 rpm, repreat all the way to 3rd.
3. Repeat 1 & 2 two more times.
4. Drive conservatively as in step 1 for the next 10 shift cycles or so. After that, resume normal driving behavior.
This effectively does what the TSB outlimes for a service tech to retrain your tranny. Worked great on mine. It will shift funny for a few days here and there as it continues to fine tune.
