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://www.tremec.com/anexos/2018_Performance-Product-Guide.pdf NEW FOR 2018: TREMEC® HP-MTF™ 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-MTF™ H-igh P-erformance M-anual T-ransmission 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. PDS: https://americanpowertrain.com/pdf/124244 Specifications & Technical Properties: GL-4 SAE viscosity 75W85 Kinematic viscosity @ 100°C, cSt (ASTM D-445) 12.1 - !!! Kinematic viscosity @ 40°C, cSt (ASTM D-445) 71.6 Viscosity index (ASTM D2270) 167 Brookfield viscosity @ -40°C , cP 65000 Foam stability (ASTM D-892) (20/50/20) 0/0/0 Flash point - °F (ASTM D-92) 338 - Conventional Fluid??? Copper corrosion - 3 hrs @ 150°C (ASTM D130) 2B Kinematic viscosity % change @ 100°C (170°C @ 192 hrs.) 13.7 Kinematic viscosity % change @ 40°C (170°C @ 192 hrs.) 18.2 Minimum pour temperature - °F (ASTM D-97) -70 Maximum handling temperature - °F 158 Maximum storage temperature - °F 113 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.

You can keep using ATF like before, or you could use GM Synchromesh or RP Synchromax, or Amalie DCT Fluid. You do not have to spend $20 a quart on the Tremec brand MTF smile

When they said it was suitable for summer conditions, I expected it to be a synchromesh clone. Something like 9-10 cst @ 100. But 12.1?! [censored]. I'll stick to Pennzoil synchromesh in my t56

I had no intentions of actually buying or using this stuff. I am more interested in what made Tremec change their tune from only recommending a conventional Dex III based ATF 7-8 cSt fluid to that of a 12.1 cSt MTF. Why such a drastic change in fluid recommendation.

The TR-6060 is also used in the newer Camaro SS/whatever other RPO codes have a V8, 07-14 Mustang GT-500, Vipers, I'm sure other cars too. Then there is the aftermarket Magnum XL version that you want to pony up and buy if you are putting a TR-6060 in anything else.
