Wanted to get some feedback regarding synthetic trans fluids.
Should I go with the Mopar ATF+4 or some other make ?

 

Go look around in the 3rd gen engine and drivetrain forum, there are a number of active threads concerning syn ATF for the 48RE.

 

Those of us who are concerned with our warranty have for the most part decided to just use the Mopar ATF+4. It was $14.50/gal at my local dealer which wasn't too hard to swallow.

If you aren't worried about preserving your warranty and want to use synthetic, several folks are happy with the amsoil universal atf, and others are using the redline c+ atf.

I would probably choose the redline over the 'universal' amsoil, but chickened out a few weeks ago at my first fluid change, and just used the Mopar stuff. I think if you're just doing a pan fluid/filter change, there isn't enough fluid removed to effectively switch brands. If you're going to switch, I'd suggest a full flush.

 

I have not been able to find a ATF+4 anywhere beside the dealer.
