I'm looking to change out my transmission fluid. I have the NV3550 transmission. Tj is at 55K now and I don't agree with the manual where it says that it never needs to be changed.
Dealer specifies Mopar Manual Transmission Fluid - Part #04874464
Though I've also heard glowing reviews for Royal Purple's Syncromax fluid. Their website lists it as an alternative for the NV3550.
Anyone around here use it, if so any pros/cons with it? Warranty issues?
