If you're doing any work on your transmission that requires you to drain the fluid:- Since the Beginning of the NVT350 the commended fluid has always been Dealer P/N 04874465. That was superceded by Mopar ATF+4.- ATF+4 is available at any automotive Part Store chain, just make sure it states right on the quart that is is for NVT350. - You will need 2 quarts.- There are alternatives such as Amsoil product Code MTFQT-EA.https://www.amsoil.com/catalog.aspx?GroupID=212- Some have reported good luck with Pennsoil Synchromesh.- One 2GNT member reported bad luck with BG SynchroShift.- If you choose any of the alternate Gear oils make sure one thing.....It states right on the bottle that it is formulated for the NVT350.
