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.
