Anyone heard of GM Syncromesh Transmission Fluid?

[Mike Spataro]

I recently read some good reviews on MTX transmission fluid sold by General Motors for FWD vehicles with manual transmissions. I cannot find any info in the search function so it must have been on a non SHO related web site. I understand Honda S-2000 owners love it. Has anyone tried this product ? I contacted a local GM dealer and was quoted $ 9.91 per quart, GM direct is about $ 5.75 per quart. Must be a synthetic product for that $$$.
Any comments? Thanks, Mike

If I am not mistaken the guys at Redline make it for Tremec for use in their T-56 trans. I believe it is the same or at least very similar to, their D4 ATF synthetic ATF fluid. I had received a couple of gallons of this fluid as a sample and have it in my '95 MTX right now. It has only been in the trany for less than a thousand miles, but it makes the shifts nice and smooth. The 1st gear syncro is still a bit reluctant at times, but overall much better than with the stock Ford Mercon fluid.

my friend just put it into his turbo laser... absolutely night and day difference in the way it shifts now.

Thank you all for the replies. I will order some and give it a try. Mike

I started with Mobil 1 ATF in my rebuilt MTX and it wouldn't shift worth a damn. So I tried the Ford friction modifier and it didn't help. Then I heard about GM synchromesh so I thought I'd give it a shot. Well it worked! She shifts great now.

Be careful when you pick some up though. There are a couple different kinds of GM synchromesh( some have additives and friction modifiers). I believe the proper numbers are:

GM part# 12345349
GM specification# 9985648

Read the labels on the bottle, it should give you some idea of which is the right one.

FYI Synchromesh is also available through Penzoil... i know its available through o'reilly auto and is around 3-4 dollars a quart.... i keep it in my store and have used it and love it for all the reasons stated above
