Well, since money is kinda tight, I went the cheaper route and got some GM Synchromesh tranny fluid. All I gotta say is THE STUFF WORKS LIKE MAGIC!

Before changing, I would get a first gear grind nearly every time I came to a stop and put it into first before stopping. Then 3rd gear would be hard as hell to engage, occassionally grinding and downshifting to 3rd was a b*tch. I was running Redline, which turned out to be worse than Honda MTF. Anyway, Ive had the tranny fluid in for about 5 days now, and Ive driven the **** outta the car, and I havent grinded 1st or 3rd a single time. Not only is there no grinding, but it doesnt feel as notchy as it did before, its much smoother in and out of the gears. I HIGHLY RECOMMEND trying this stuff if you feel like your tranny is starting to get the infamous 3rd gear grind(and in my case 1st as well). Obviously it is not a permanent fix to the real issue, but it seems to be a great work around for the time being for someone with slight tranny or clutch problems that make shifting difficult. I plan to run the stuff even when my tranny is working properly.

 

How much did a tranny fuild change cost with the GM stuff?

 

I got mine from a local Pontiac/GMC dealer. Cost me about $9/quart. I picked up 3 quarts, used almost just over 2 quarts for the change.

 

Part number for the GM Synchromesh?

 

Almost 3 times the cost of Honda MTF, it better work well! I might try this stuff out soon.

This is for the friction-modified GM Synchromesh.

 

I DID NOT get the Friction Modified additive. I just got the regular fluid and it works great. Part number 12345349
I think the Modified is even more expensive.

 

Good to hear..
