one thing that bugs me a little is, his profession isnt lubrication.
I dont know whats in manual trans fluid compared to ATF, thats why I posted this here. I was kinda hoping the real professionals in lube would chime in on rather or not the zddp is needed or helpful compared to ATF4. there have been tranny failures, but I havent found a single incident that had proof it was ATF related. People just say Owell and send off their tranny to get rebuilt for 5k+ instead of finding out what went wrong. On the other side of the coin, there T850 trannys that have a couple hundred thousand miles on them using ATF4 without problems.
I still plan to keep using my Redline C+, this is just curiousity.
