Tranny Fluid Question

[Obsol3te]

Well, I have a TKO 500, and it's about time to change the fluid.
They reccommend GM Syncromesh for the tranny so I was wondering.
ACdelco Syncromesh=GM Syncromesh right?
I also heard that the Penzoil Syncromesh was the same thing as GM Syncro because they actually made it or something?
Penzoil stuff is a little cheaper and would go that route if that is indeed the case.

Anyone know?

It's really really hard to get accurate info about this - i did an long search some years back. To add to it, there are different flavors of the GM synchromesh fluid (that you'd get from GM) alone!

I wont begin to try and recall what I had found out because I'm sure I remembered it wrong.

I might get with the Tremec and ask them for a PART NUMBER of the fluid they desire you to use.

Good luck.

Yeah, guess I'll have to.
Curious, would they have it(GM Syncro) in stock at a local dealership(GM of course)?

The GM syncro mesh is recommended. I have a stock T-45 and a stock T-5 in my Mustangs, I have just used regular Valvoline Fluid ATF. I haven't had any issues, but it is really just up to you if you want to spend an extra few bucks a quart.

I wouldnt compare what fluids a T45 or T5 takes, versus a possibly brand-spankin-new TKO (with possible warranty concerns).
The way the post read [suggested to me] that any old ATF could suffice. I'd respectfully disagree.

I'd say check out Red Line. They have both kinds and I'm sure they could tell you which one you need rather than getting the wrong one.

Yeah I know what you mean, I am not trying to talk him into it. It just sounded like he wasn't sure to use that or not. I would use whatever the manufacturer says. A few bucks more is worth it.

I use the Penzoil Syncromesh. It's about $6.25 for a quart at Autozone. It says right on it that it's for use in GM manual transmissions requiring GM part # 12345349

You can use certain types of Redline and Royal Purple has a good one called Synchromax I think. If you want the part number for the GM synchromesh, D&D performance has it on their site under install tips for the TKO
