Okay, here's the story...cold notchy difficult to engage 1-2 shift when cold (no grinding). I tried Redline D4 (twice) with no improvement. Then as a result of input from Cobra drivers I tried <gulp> GM Synchromesh and presto...buttery smooth shifts! Give it a try it might just save your transmission from going under the "knife".

I believe Tremec specs GM Synchromesh for the TKO 5-speed. Sounds like it works well in the 3650 (does Tremec spec Synchromesh for all its transmissions?).

Anyone done dyno testing with Redline vs. Synchromesh vs. Amsoil, etc.?

 

[01GTCOUPE]

Hey, 2002gt, what was that part number for GM Synchromesh? Thanks for the post. I read the same thing about a year ago over at Corral.net, I think.

 

[TrueBlueBullitt]

I would like the part number as well. I was about to try this stuff...

What do you think?

how many quarts did you use? and where is the tranny fill plug? I think I found it back around above the crossmember area. Anybody with the answer reply.

 

[2002GT]

GM Synchromesh part #12345349. Fill plug is above drain plug on passengers side. With vehicle level, it took about 4 1/3 qts. You can find at any GM dealer at a little over $9.00 a quart. Will need pump to pump fluid up into fill hole. You can purchase at Autozone, Advance auto or PepBoys.

Thanks 2002GT, I appreciate the info.

Why not email them and ask them what differentiates their product from Mobil 1, Redline, and Synchromesh for the 3650 application?

 

[barry bullitt]

My car's at the Mobil station now having the GM syncromesh put in. Will let you know in a few hours but I also think it will alleviate the problem.

 

[Driven]

I changed mine yesterday to Royal Purple and I can't believe I waited this long to change it. It made a huge difference in the feel of the tranny. Shifts really smooth.

 

[barry bullitt]

Got my car back with the GM syncromesh but I've only driven it a couple of miles. Big improvement in 1-2 shift. Now just a snicket when before there was a grind if I shifted too quickly. All other shifts are like everyone else said, buttery smooth. Shifted flawlessly 1-2 after only a couple of minutes. Before it took about 10 minutes until the crunch went away. Basically the problem is solved.

 

[Bullitt4003]

Barry Bullitt, where did you have this done?

 

[barry bullitt]

At the Mobil station by where I work. They picked up 5 quarts of GM syncromesh from Cauley Chevrolet. The shifts are so much smoother I also recommend everyone switch.

I wonder what are the odds of Ford switching to GM Synchromesh from the factory? :wink: Before you laugh, it would certainly cost Ford less money in the long run...

Again, I'm having good luck with Redline D4 ATF (better, but not perfect), but I might try Synchromesh as that appears to be what Tremec specs (and perhaps used when designing the transmission).

 

[barry bullitt]

I understand Ford did switch transmission fluid on the 2002's. They dropped the Mobil 1. I forgot what they switched to though.

 

[NV02GT]

My 2002 GT Owner's Manual says that my T3650 tranny is filled with Synthetic Mercon ATF. Slight notchy 1-2 shift only for two or three minutes when the car is cold and temps outside are in the 20s. I can live with it for now, but if it starts to bug me, I'll go with the GM Syncromesh.

Maybe they did switch to Synchromesh :wink:. "Synthetic Mercon ATF" is a spec (not a brand), so it could be any synthetic ATF that meets Mercon specs...

 

[Hank]

I sent Tremec an email yesterday about using GM Synchromesh fluid and here’s the reply:

Henry,
The GM synchromesh fluid will not damage the seals or other components. The oil from the factory is Mobil 1 synthetic ATF, Texaco offers a non -synthetic Dexron III spec. ATF that you may also want to consider. Avoid any magic additives or snake oils , they can do more harm than good. I hope this has been useful.

Subject: Best fluid for TR-3650

I have a 2001 Mustang GT Bullitt with the TR-3650 transmission. Many people with this car and tranny are switching to GM synchromesh ATF part No. 12345349 as it seems to be better than the Mobil 1 ATF recommended by Ford. Will the GM synchromesh damage the seals or any other part of the transmission?

Thanks,
Henry Blattel

 

[Mus408]

Many thanks to all who have shared this info. I will make the change ASAP,to get rid of that cold grind into 2nd gear!

 

[Bullitt2981]

Tried the GM Synchromesh and I love it! It took care of my concerns MUCH better than the Redline D4 and the stock Mobil 1.
