Tremec's New HP-MTF Transmission Fluid

[Jim Vander Wal]

TKO-600 new in 2004, Liberty mods in 2011 or 12. 65,000 miles or thereabouts.

Started w/ Dexron as recommended, ran Cobra Valley's Ultra-Shift, Royal Purple SynchroMax and finally Red Line MTL. I didn't notice any real differences in shifting with the various fluids although others have indicated a difference. Liberty didn't mention any serious wear issues during the rebuild/mods. Planning on continuing with MTL when I complete the current build.

I too have heard about running the fluid a bit low, perhaps a third of a quart low, sorry don't remember the exact amount Supposed to improve shifting due to less fluid for the gears & synchros to turn through.

Well, I know that Ford and Tremec issued a TSB many years ago for the TR3650 clarifying that "The full fill level is approximately 19 mm (0.75") below the fill hole." That can be found here: http://www.stangnet.com/images/stori...s/04-15-06.pdf Now, I don't know how different a TR3650 is from a TKO, but that could be the origin of the urban myth. It would be helpful if someone would post "yes, I experimented with different levels extensively over the summer of 2010 and found that 1.3" below the fill hole gave me the best performance in my TKO600." But, that probably won't happen....
