mtx tranny fluid besides redline?
 

Hey all. Just got a big gift card to advanced auto. Curious if anyone has ran Mobil 1 , royal purple, or any Castrol 75w90 products with luck ? Just got my car 2 months ago with 25k. Thought I'd try and use this card up if I can. Any of these for the rear diff ? Have no problem buying redline its what is 100% recommended I just don't have much else needed at an auto store at the moment. I haven't seen much posted on here that's not a diy or redline post. Thanks!

Unless you're tracking your vehicle routinely, you'll be fine with any of the major synthetics. I've used most all, including Redline in Z06's and Vipers (both T-56's), and noticed little if any difference in shift quality. Get your money's worth out of the card.
