Tranny Fluid...

[BadMoJo]

Hey, I am gonna change all my fluids soon. What do you recommend for tranny fluid, as well as differential fluid?

[tristarx]

If you car is a daily driver that sees the track very rare, then just get the regular Valvoline or name branded 70w90 or 75w90, etc. diff fluid for your tranny and diff.

If you attend the track alot per year, then we recommend using the good stuff which cost alittle more such as Redline oils.

i personally use Mobil-1, can't remember the weight, Mobil-1 engine oil is excellent, so i trust them with the diff and transmission as well, it's $8 a quart, like tristarx said though, redline has quite an extensive product line and is very reputable, they are sure to have something to fit your needs, if i wasn't using Mobil-1, i'd use redline

[BadMoJo]

so, 70w90 or 75w90 for both?

[tnord]

i'm not sure what the weight is, it doesn't say on the bottle, but if you're getting Mobil-1, there's only 1 weight available to my knowledge, if you really want to know what weight is appropriate, call up redline, i'm sure they'd be happy to help, i'm sorry i don't know more

70w90, or 75w90 is fine.  Those are the most common ones, so anywhere in the range of "70"s w "90"s.

If you decide to use Redline, just grab the "MTL" for the tranny and 75w90 for the rear diff.

Some people like to mix and match adding 1/2 quart of MTL and 2 quart of 75w90 Redline in their tranny, just a matter of personal preference and what works for your tranny.
