Ordered and am having the 4L65E Stage 5 built for Oprah. Built up 4L60E aint gonna take it anymore. FinishLineTrans is building it. http://finishlinetrans.com/transmissions/4L65E-Level5.htm
Anyway. They recommend conventional ATF and not synthetics of anykind. Kinda suprising. So I got two cases ( Trannie Cooler and big ol trannie fluid spin on filter) of NAPA High Performance ATF conventional.
Never would have thought a dino ATF would have been recommended over a synthetic but I learn something new everyday I guess. Builders dont like the "friction modifiers" in the ATF synthetics. Looking forward to seeing the temps....with the 4L60E I run 160 degrees consistently....
