Hello .. Just got the trans fluid changed at a Chrysler dealer and used Mopar full synthetic trans fluid. Never used synthetic before, should I expect a difference in towing performance? Towing a 6,000 lbs travel trailer. Have 84,ooo miles on dodge. Had cooling system fluid changed too . Had been showing an increase in temp. No boil over or steam but the extra cooling started running until temp came down.
thanks

 

The ATF fluid (the original ATF transmission fluid from the factory) is full synthetic. This is the only fluid that should be run in your transmission
