Well I might have spoke too soon on that. I used to run ATF in all my race stuff. But according to A&A, I should be running ATF +4 for OD trans now that I am running their clutch pack....So we will be switching this year.


That's odd, I wonder why they recommend that? ATF +4 has added friction modifiers that allow the lock up clutch to SLIP on application to combat lock up converter shudder ...


One of the clutch packs they sent me has no grooves in the clutches, so I am not sure, but that's one thing I know was different on this build than past builds. We also squeezed more clutches in the pack with their setup...So maybe they need a thinner film...
