GM Syncromesh

This product from GM was suggested as MTF for my B16 cable tranny by Steve from Hmotors. I was gonna send it back to him it was behaving so badly, this stuff took care of all the whirring and syncro problems that were causing it to pop out of gear. I have not seen anyone post about it before so I figured I would throw it out to yall. You can only get it from a GM dealer parts department so you may need to shower 3 or 4 times after getting it but the mental anguish of entering a GM dealer is well worth it now that my tranny behaves properly.

The GM syncromesh is great. My old tranny (5-speed) would grind when shifting and make whirring noises also until i added syncromesh fluid into it then it was very smooth and quiet. GM does soak you for the fluid for $$$ but it is worth it. i just did the jdm h22a w/ lsd tranny swap and that was the first fluid i bought.

nice find man, sounds like it does wonders.
