Did the BG for the differential already have a friction modifier in it for the posi, or did you have to add some?Changed mt-82 and 3.73 diff fluid with BG.
7500 miles on the car, I'm funny that way.
Trans fluid was pretty good looking coming out.
Diff fluid was BLACK, and there was a huge amount of deposit on the magnetic drain plug.
Butt dyno: the mustang pulls much more quickly and freely with the new fluid.
Revs up super fast and there is much less "engine braking"
Broke it all in on a 750 mile road trip. Impressed wit the newfound smoothness and it seems there is a bit less nvh during highway cruising.
Thanks OP Mustang!
