Guessing that it is this stuff:

 

Changing it is pretty easy.

Diff is self-explanatory. Top bolt is fill, bottom is drain. 24mm for one, 23mm for the other.


Trans, remove the butterfly brace and aluminum tray thing. Drain and fill are on DRIVER'S SIDE. DO NOT REMOVE THE ALLEN BOLT ON THE PASSENGER SIDE.

Top is fill, bottom is drain. Both are 24mm.

2qt in trans, 1qt in diff.

I used Amsoil MTG in trans, SVG in diff.

It's an improvement over the Redline bullshit i had in it before, but i think i might need to try the Motorcraft in the trans.

 

Good stuff. I'm reading that others are doing back flips over this motorcraft stuff. There are a few different types and I wanted to make sure and get the right stuff.

I know various gear lubes make a HUGE difference on these little cars. I switched my 91 from new stock fluid to redline and the third gear noise went away. People are saying this stuff is MUCH better.

Can anyone verify that this is the right stuff?

 

Verified that this is in deed the correct stuff.
