thanks again to xviper for the tutorial. My fluid is only 2.5K miles old - but was already gray, sludgey and my plug was covered in shavings. I added one step to your process though - I temporarily put the drain plug back on and pumped a little left over 75w90 fluid from another change into the diff and let it sit for a little bit and then drained it out before continuing on. Same sort of premise as pouring some oil through the filler tube while the drain plug is out when changing your oil - gives me that little bit of extra security that I got every bit of the old fluid out...

took the car for a nice drive by the beach today and overall it just feels great with the new tranny and diff fluids in...partly psychological - but mostly the MT-90 making things smooth. I love rev-matching in this car...

oh yeah - I did this all without jacking the car up because I'm lazy...

what kind of difference, if any, did you rally feel after swapping the two fluids?

I did mine last week and used Mobil 1 75W-90. I don't exactly know how to describe the difference to you but it is clearly there. I would say it feels like the rear end spins quicker and with less friction.

pretty much what I said in my first post - overall just smoother...mostly psych. probably - but I feel a lot better really winding it out on back roads and keeping the revs high to stay in the power band...

How did you change your tranny oil without jacking up the car?

by only changing my rear diff fluid

I did the tranny fluid a couple weeks ago and jacked from one corner...

An honest answer. I can't imagine anyone telling the difference between diff fluids, brand vs brand or new vs old, unless they are one hell'va lot more sensitive than than the average male!

Check back in a couple weeks, and I'll let you all know if I can tell any difference. I just bought a few quarts of Redline 75w90 today.

It takes less than 1 quart to change the diff fluid.
