I have a performance 2004R built with all the high performance parts (billet input shaft, HD clutches, etc). The vehicle is not driven much except when nice. I did a fluid change (Dexron Mercon) and added a Hughes Aluminum pan. I noticed that the 1-2 shift seems softer than it was before, almost a slight flare when at higher RPM's. The 2-3 is quick and firm as is the 3-4 shift.
The TV Cable is fully adjusted properly and is fully extended when at WOT. Trans temps are 160-180F max
What controls the 1-2 shift and if something is starting to go bad, what signs would be present?
Is Dexron Mercon the best fluid? (Former fluid was really good, red with no debris) (trans was built by Perfromance Trans in California - Bruce Toelle - Many years ago).
