I can get the royal purple synchromax for free at my local parts place. (I use my truck for work occasionaly and my employer lets me get more or less what ever parts I need from the parts store for free).

I was wonderin if anybody had any experience with it?
It is made specifically for manual transmisions that call for atf so it sounds perfect for my g56 and transfercase.

All comments welcome.

 

I do light - medium hauling and have it in both my NV5600 and Transfer case with not a problem for 10k miles.

Does the 5600 call for atf?
