Need help with trans/diff fluid change
Ok, finally going to change the trans fluid and rear diff fluid in my '06 M6, and I need a couple pointers...
For the trans, I'm going with Royal Purple Synchromax, 4.6 qts. This should be a simple drain&fill operation, correct?
I have a little pump to fill up the trans w/ new fluid. Anything I need to know beforehand?
For the rear diff, I'm going with Royal Purple Maxgear 75-140, 1.7 qts with no additive required, right?
I've looked at the diff but the only thing that looks like a drain plug is a BIG plug about halfway up the right side, am I missing something? Or do you have to pull the whole cover off to drain it?
I called Royal Purple this morning, these are the fluids the tech recommended and said they meet or exceed all GM specs so there shouldn't be any warranty issues.
I have done some extensive searches on the forum, read a lot of opinions on various brands but haven't quite found the "how to" I'm looking for. Thanks for the help!
