Gentlemen - the current spec for the Tremec 600 and all cousins is the GM stuff or Dexron III / Mercon ATF - much cheaper

I called the Tremec tech line a while ago and asked the same question. Their tech guy stated that Dexron III should be used for the first 1000 miles and then you can use the GM synchromesh. The tech guy stated its the same as engine. Would you use synthetic to break in an engine. The answer is "NO" in my book. Pennzoil makes the GM synchromesh. You can find it at AZ and its much cheaper.

Here read this:

www.5speedtransmissions.com/faq.html#BreakinProcedure

What is the proper break-in procedure for a TREMEC TR-3550/TKO 5sp?
A:

Put 3qt of good quality ATF (Auto Transmission Fluid) (Dexron) into the transmission. Pour in through shifter mount, or through one of the top plates. You can use the fill plug on the side of the transmission also (afterall, that's what it's for!). It's just easier to pour it in from the top if you can.
Put car on jacks, run the transmission up and down through all gears repeatedly for 15 minutes. This will allow the gears to break in properly (yes, with the engine running)
After 500-700 miles, drain the ATF, and put in 3qt of the GM Synchromesh fluid, the part number is 12345349. If it's a race car only, then switch to the GM Synchromesh after the initial break-in.
Don't use synthetic lube for 6000-8000 miles. In fact, we don't recommend synthetic, just stick with the GM Synchromesh.

Baby - my quote is direct from the 600 data sheet that arrived with the box this week, same as the one a year ago with the previous 600 - you may rely on a pre 500 or 600 web site, but I will go with factory recomendations................

Wow, you mean I put GM crap in my Ford?
No, not crap. Synchromesh! Crap would be too viscous, especially for break-in.

Cheers, John

I used the GM stuff when that was the only listed option. found it for $7 from a local Caddy dealer, but the world has changed. The operative words from the mfg ( quoting Baby ) you CAN USE, after breakin, the GM stuff. - why?
Guess it is OK, but so is Mercon. When the factory says Mercon, I have to ask - why should I pay more for some botique crap that I have no scientific basis for the premium price demanded. Thanks to TREMEC to the alternative choice.

I held that thing in my hand and was not sure why I'm putting anything with the GM name in a FORD! But I did it.

So get GM Syncromesh

There's some new ATF out there that's supposed to be really good stuff. I think it's called GM Synchromesh. Try that.

So, here I am several years later trying to answer the question "What is recommended lube for my TKO-500?" Thank goodness you beat this horse to death because otherwise I would not have found this. Here is my point: just because you've beaten a horse to death doesn't mean you have answered everybody's question...especially they mechanically impaired, such as myself.

I've run synchromesh (penzoil brand) in my TKO's and it works well. That being said I've also driven a car that had Mobil 1 synthetic ATF in it and could barely tell the difference in the shifting.

I have 1800 miles on my tko600 and I am getting ready to drain and refill the trans. My question is... what fluid do you guys recommend?

The answer is still Synchromesh...

Avoid the exotic products claiming added benefits.

The Pennzoil version is much less expensive and is found in the gear oil section at your local parts store...

The TKO series has bronze blocker rings. The synchromesh works well with those rings. Synthetics tend to be a little too slick for the bronze metal-to-metal rings...

So I take it that the 3 bottles of Pennzoil Synchromesh that Mike Forte sent with my TKO600 are suitable?

Pennzoil #7161193501 cost $8 at the parts store, same stuff made by the same company
