Hi, 
Tought it was time to change the ATF in my 85 Vanagon and was going to try 
some Red Line Synthetic ATF since I've heard fine good things about their products. But I am perplexed
on what to use for the Auto Diff. ( is that the same as a Transaxle?) 

Red Line offers a number of different ATF and Gear Oils.  And I want to make sure I' selecting the 
correct product for the environment. 

The average temperatures this winter around here will be about 40/80F.

Thanks all for the help.

Vince
