yea teh 15k service is nothing too drastic. ugh my 30k service is coming up here soon, that should be fun.

 

do you guys know what brand the fluids are? or can i just use any old fluid?

 

I'm pretty certain the manual only says CHECK tranny fluid, transfer case fluid and differentials fluids at 15,000, not REPLACE. Obvously if they're ****ty or low then yeah, replace, but not required... 30,000 is when it actually says replace right?

 

You, sir, are correct.

 

Use the OEM Diaqueen in the diff and transfer case. The transmission fluid is personal preference. Redline MT-90, BG SyncroShift, and Pennzoil Syncromesh are all different transmission fluids people have used. I myself just changed mine with the OEM MR Diaqueen transmission fluid. We'll see how it works out.
