I presume this is like the difference between anyone's 20W50 motor oil and VR1 (IE I know the VR has additional Zinc), just wondering where the difference is that everyone is seeing.
We have run Cat HYDO for a long time for the same reasons mentioned here but it does tighten the converter up about 250RPM. This sounds interesting and would like some more information.

Also, where is the best place to purchase Transynd?


I'm interested in this question as well, is the Castrol, Mobil etc EXACTLY the same as the Allison Transynd. If I understand correctly Castrol makes the Allison labeled fluid so I think it would at minimum be the same but maybe I'm wrong. I would obviously like to save a few bucks if one was cheaper and the performance was identical.

if you want to best you have to pay.

Transynd and Mobil 1 Delvac are the only two trans fluids that have been meet the criteria of Allison's TEC-295 spec and passed that I am aware of. Others have claimed they are as good but haven't submitted their fluid for testing to that spec.

Per Tom...

" Mobil 1 Delvac It's good stuff. Equivalent performance to TranSynd. I personally worked with ExxonMobil to test it and approve it for Allison."

Looks like there are more than that touting 295 and this looks like an allison website but sometimes it's hard to tell if it's the actual company or marketing levels, looks legit. Thanks for the video, looks like it was made 5 years ago, they may have had multiple spec submissions and approvals by now.

Is he still with the company? Sounds like he would be the guy that would know without question. Thanks.

Tom, has been retired from Allison since '09

as I already stated...

I'll stick with the original and what I have used for 17 years, Allison's Transynd

I use this cooler in both cars with FTI fluid and it can be hot lapped all day long and never see higher than 170, usually runs about 130ish. With the high gear deal it has seen 220 running 20 minutes apart but it's about 190-200 with any realistic time between runs.

We have doubled both cars for years and the trans in the 565 dragster has been in the car for 5 seasons with one trans fluid change, we use only BTE Trans fluid. I know they don't make it, don't care. Never see anything over 180 no matter what we do. Like engine oils, we use New and Used oil analysis through Schaeffers Oil to monitor what we have.
As long as you like what you use, then keep using it if you have no issues. Taking the S10 up for 17 rounds in a day showed me what I needed to know about BTE Trans Fluid. Plenty GOOD!

17 rounds you da man! That's a sweet day at the track right there.

I agree the BTE is good it's a semi synthetic Lucas. Good stuff.

of course you will, you first read about it from me right here years ago.

You're welcome.


I agree with Steve. I should have used it years ago when you first posted about it. I won't use anything else again, that's for sure. My friend who owns a RV repair biz uses the "knockoff" but I will stay with the original. Gotta pay to play....

The spec is A295.
It means it is approved for use in Allison transmissions as an alternate to Allisons own Transynd fluid.
In the real world they cannot deny any warranty related claims to having the incorrect fluid as long as you can prove the A295 rating. A few players have had their formulation approved. Shell Spirax being one I know of.
Formulation between all the players will be close, enough that Allison would approve them for use as a substitute.
I have forever used "F" and got about 600 runs @over 1000hp and 2800# when the planetaries started to spall.F does not have "cushion" in it, it has lubricity but no resistance to friction or impact. It was never developed for what we use it for, but it performed great as far as clutch wear. Last freshen I switched to the Spirox A295 and do not have it back apart for any reason so the jury is out. However the "seat" says it does not seem as hot on the tunnel, I dont put a fan under the car anymore, but no actual temps or proof to say it it better.

The spec is TES-295, it was written by Tom Johnson of Allison and was the performance spec Castrol used to develop Transynd.

I used to run Transynd because my old boss let me take it from work, once per year. Since leaving, this is what I run now, and it's pretty much the same fluid. Looks and smells exactly the same. I just serviced the trans in my truck, had about 65k on it, with this fluid, and it looked the same coming out of the trans as it did coming out of the bottle....I was brutal to my stuff on my move too, had a cooling issue on my move back from florida and trans never saw below 225* from florida to colorado, back to florida, and back to colorado again, towing two different trailers. Trans works as it always has. Cooling issue has been repaired now, and trans doesn't see above 175* any more.....

Ed is right on this, even I'll agree, there isn't a better fluid available. Here's the link for the Amsoil version that I run:

Mark, just keep in mind that Amsoil is not TES-295 tested nor approved

Amsoil says it meets the spec, not Allison who is the author of the spec for their transmissions and built the test stand used to test all that applied.

So Amsoil IS NOT on the approved list and retail is cost much more than Castrol Transynd, why would someone want to use it then?
