Just serviced the trans in a new to me 2009 grand caravan. 110K on it, factory filter, so I am pretty sure it hadnt been serviced. Trans oil didnt look too bad, neither did the filter. Typical accumulation in the pan/magnet. Filled her back up with Castrol ATF+4 and a new filter. She's running and shifting really nice. As many horror stories as you hear about the 41TE/Ultradrive, my experiences have been pretty good. The wife's pacifica has the same trans. No issues there either. I wish I could say the same thing about the follower/rocker assembly on the 3.5 in the pacifica!
