Interesting update from Tremec

limp · Apr 25, 2022

Sent a comment to Tremec about using Mobil 1 or Amsoil Syn ATF fluid in my TKX. Previously they had recommended dexron III/Mercon, and I wanted to ask them about using a synthetic fluid instead....
This time they recommended a " synchromesh" fluid ......

Interesting! That seems like the new "go-to" for performance transmissions now. Did they say anything about adding friction modifier?

I've been running Royal Purple in my Z-spec T5 since I opened it up in 2010 to change the speedo drive gear. A colleague who works in heavy machinvery transmission development made the recommendation and I never would have believed it made a big difference, but it shifts noticeably smoother.

Tremec seems to flip flop on it's recommended fluids all the time. Not the first time i've seen them go back and forth.

No, their comments are pretty brief....
Nothing against Royal Purple, but its ONE of the fluids tremec has not tested in their transmissions, at least not since I last checked..... T5 specs and TKO/TKX/Magnum take different fluids....

It would be my luck to pick the one that didn't work.....LOL
$120 for 4 qts of Tremec HP-MTF... if you can find it....

Put a Tremec in my car 15 years ago and Syncromech was what was recommended.

From what I understand, the TKO's are different?

Tremec likes Synchromesh. Not a secret.

Heres the kicker for me...They say if you're not racing them its a fill for life deal....It can't possibly be a fill for life transmission if theres a break-in procedure...LOL

The instructions I got with mine say to break them in for 1500 miles with Dexron-MerconIII than drain and swap out to Syncromesh but doesnt state which brand is preferrable for maintaining the warranty.....

When I called about preferred Synchromesh brand they told me to use Tremec HP-MTF..When you read the MTF information it shows all of the brands its supposed to replace so like others have stated it varies.................LOL

High quality transmission fluid suitable for use in any TREMEC transmission. Available in single quarts or 4-quart cases, enough for a full oil change on Magnum, TKO, T-56 or T-5 TREMEC. Check your capacities. Intended for use in manual transmissions that require GL4 75W85 MTF, synchromesh, or DEXRON®-III/MERCON® fluids. Not compatible with automatic transmissions or hypoid gear differentials.

Improved load carrying capabilities at all temperature
Stable viscosity
Engineered for Magnum, TKO, T-56 or T-5 TREMEC transmissions
Provides good shift performance in cold temperatures
Compatible with yellow metals and carbon lined synchronizer materials
Improved dynamic seals performance and reduces leaks
Excellent wear protection at high temperatures

The part that throws me off a lil is the high temperature protection part..I have a temp gauge on my TKO600 and it reads 66 celsius on the highway which is about 150 farenheit...

Pennzoil Syncromesh was recommended for my tk0 600. Still put Dexron 3 in my 2.3 T5.

JMG9350 · Jul 2, 2023

Any updates on the use of Royal Purple Synchromax?

limp · Jul 3, 2023

I ended up using dexron 3 in my gear box...Not running yet though... " its a hobby" .... LOL....
After re reading this I do want to stress that while the TKO models took syncromesh, the TKX and T56 do not.... At least thats what I read...

KZGUNS · Jul 5, 2023

They told me syncromesh for my tko600 as well and it all i've run the last couple years

I would send your question directly to Tremec.. They have responded to all of my emails....

Hanlon just told me not to use Royal Purple specifically. Dex 3 non synthetic for break in, Penzoil Synchromesh after 500 miles.

Hanlon told me my SROD bellhousing would NOT bolt up to my TKX.......

JMG9350 · Jul 30, 2023

I did call Tremec. They recommended their Tremec MTF or Mobil 1 Synthetic DexIII. And that they do not recommend Synchromax.

That's clear as mud.

Yeah, ... I am going to run my Dexron III/Mercon for 500 miles or so than change over to a synthetic ATF.. Mobil 1 probably, maybe Amsoil... If I find some of the MTF maybe that..... TKX.....
