Not sure why I got a dislike, my info is accurate.How do the clutches look that you can see straight above the pan, any delamination? Does the rad look original? It is the original OZ code trans? Those trans will have firmer shifts and higher shift points, even at part throttle. Water/antifreeze is what pink ATF says to me, maybe give it a taste. I think the M1-206 oil filter will fit the best with your full length headers.
