Diff and tranny change due?

mousitch · 04-16-2012, 01:43 PM

Got a diff and tranny fluid change next weekend. Warranty out by August but have over 27000 on both.Was going to change out with RP(tranny) and RL(diff). Both were excellent in the vert, with the RP really making a difference in shifting.

Do it now or wait for warranty to run out? What do ya think?

Do it! I did mine over a year ago, have close to 15k miles on the new fluid. Did the same thing you are planning on doing, RP in the tranny and RL in the diff. No issues here.

I'm planning to use RL in both in a couple of months.

I went with RL 85W-140 in the diff and a 50/50 blend of RL MTL and MT-90 in the tranny.
My Z4MC sees a lot of track time
