It's time to change the fluid in the rear end, and I can't remember which grade you're supposed to use. Does anyone have that info handy? I rmember that last time I used some Mobil 1 goop.



Thanks in advance,

I was planning on running the 75w90 in my 5600 trans also..... think it'll be alright in there too?... ... i know the 5600 calls for "mopar m/t fluid" but the 4500 just calls for 75w85

The 75W-90 is not recommended for the NV-5600 Transmission, as it is too thick, and has the wrong additives for that application as well. You could use the Amsoil (MTF) Manual Transmission Fluid. It will take about 4 Qts to fill.
