I want to change the manual tranny fluid in the 2004 dodge 3500 Ram CTD with the 6 speed (this is the big cast iron sob tranny) if I read the book correct it takes the Mopar Manual Tranny Fluid. Is there an aftermarket maker of this stuff or do I have to go to Chrysler *******? Also how much does the manual tranny hold?

Book says 75w90 for the front and rear axles. This seems a might thin for the rear - am I missing something here? Also what are the capacity of the front and rear axle? I was going to go Mobil 1 is that good stuff still?

 

This is the same oil as Mopar, should be available at auto parts stores. For the NV5600 - PENNZOIL SYNCHROMESH FLUID is specifically formulated for synchromesh transmissions used by Chrysler transmissions requiring Part No. 4874464 (Specification MS-9224).

 

The MOBIL 1 (GL-5 )75W-90 will be fine for this application.
