Tranny fluid

A//// Guy · 01-23-2007

Straight from Mobile One:

The GL-5 lubricant has high levels of EP additives which is sulfur and will erode yellow parts found in many transmission such as brass and bronze parts. Therefore Mobil does not recommend our product be used in any transmission using yellow metals under any circumstances.

States right in the owners manual... GL4 for the tranny and GL5 for the diff.

South Central Imports stocks the MT90 and MTL, going there after work today and getting some cheap GL4 to flush first from the nearby Checker.

3 quarts (2 mt90, 1 mtl) is enough for the tranny/xfer case?

3 is all you *should* need, but depending on how you're extracting it from the bottle it wouldn't be a bad idea to pick up a 2nd bottle of MT-90 just in case.

Fill tranny with 1 quart of MT-90, then MTL, and then top off with the 2nd quart of MT-90. Fill xfer case with leftover MT-90.

The xfer case doesn't have any yellow metals in it does it?
