I run this stuff in my Regal along with several other memebers on my Regal board and so far so good. It's a full syn ATF, which many may say is a no-no...but I've heard and experienced only good things about Amsoil products. Thoughts of running this in a TH350?
There is nothing no-no about running synthetic ATF. It handles heat much better, and Heat is what kills transmissions in everyday driving. I run Red Line D-4 in my SP 400
cool, ordering up the Amsoil then. Thanks. there are mixed feelings about syn ATF on the L67 motors w/ the HD-4T60, it may be the type of trans we have, not sure...but like I said, i've had it in for about 10k miles and havent had any problems.
