And for the differential - 75W-85 just does not exist around here. I found synthetic (I beleive it was Mobile 1) 75W90 all over town as well as 75W140. Book calls for 75W85 - just how critical can it be? I mean, isn't replacing 7 year old fluid with ANYTHING CLOSE better than 7 year old brake and diff fluid?
I picked up two quarts of Mobile 1 5W20 for the transmission tonight. I want to do it all before the Dragon - which is 5 1/2 days away. Gonna end up paying NTB or my local independent garage - I don't live where cars can be worked on in the driveway anymore.
I replaced my diff with Amsoil 75W-90, and swapped out my tranny fluid with Amsoil 5W-20, both full synthetic. Can't say anything about the rear, but the gearbox is definitely a lot smother when shifting.
Don't know anything about the brake fluid since I haven't changed that yet.
P.s. you spelled "Ultraguage" wrong in your sig
