So it would appear that Tremec has come out with their own branded MTF for use in ALL Tremec Transmissions from 2008 and newer. I just stumbled across this yesterday and figured I would post about it to get some thoughts on it from the experts. All the of the Tremec transmissions I have owned T56 and TR6060 have called for a ATF (Dex3) type fluid. If you look at the specs below you will clearly see this is NOT like an ATF. This is from the Tremec 2018 performance Brochure: http:/
NEW FOR 2018:
TREMECÂ® HP-MTFâ„¢ MANUAL TRANSMISSION FLUID
We get the question all of the time, "What kind of oil do you
guys recommend?" And now, we're pleased to announce our
definitive answer --
"TREMEC oil, of course!"
Developed in conjuction with world-class automotive and
industrial lubricant producers, TREMEC's new HP-MTFâ„¢
F-luid is designed to
provide an ideal balance of rugged protection and responsive
shifting in accordance with the OEM-level standards of
TREMEC's own engineers.
Compatible with all TREMEC manuals produced from 2008-to-
current, HP-MTF is also yellow metal safe, meaning that it may
also provide benefits in non-TREMEC units, such as the early
3- & 4-speeds that TREMECs typically displace. Although
acceptable for use in all climates, HP-MTF is especially well-
suited to summer-like conditions; and while developed first-
and-foremost with street performance in mind, is capable of
supporting severe-duty use in competition applications.

This stuff retails for about $19 a quart so I am not about to run out and buy it for my TR6060 just yet. What this does tell me is that running a thicker fluid won't make your Tremec implode like many would have you believe. I also tells me that in high performance and severe duty Tremec would like to see a thicker fluid used. However, they due allude to summer weather performance so based on the 12.1 cSt this would not work well for winter use.
I doubt that this new fluid would be OEM approved for warranty use so until my warranty runs out I will make sure the fluid in my TR6060 drains out "red". But after that I am inclined to run something thicker such as Amsoil MTF or Redline MTL since I don't need to worry about cold weather performance. My SS Sedan is a garage queen when the temps get below 40F.
Would like to get some input from the experts on Tremec's new recommendation on a using a true MTF and a much thicker fluid than the typical 7-8 cSt ATF based products. What new alternative products does this open the door for using? Is there something special in the additive package? I doubt it but would be interesting to know. Unfortunately right now it is to pricey to buy just for a VOA. americanpowertrain.com/ pdf/ 124244
