So my youngest son came home with a low mileage 2015 Jeep Renegade 4x4 with the 1.4L and a 6spd manual transmission. I can't seem to find out a lot about the transmission. The manual calls for MOPAR C Series Manual & Dual Dry Clutch Transmission Fluid. The must think a lot of it because runs about $23 per quart. I see it is 75W and GL4. Is there something so special about the synchros that it requires this special fluid?
