Ok so i finally couldnt take grinding third gear anymore so i found some synchromesh at a local buick dealer today and then went and swapped out the honda junk.....I was a lil skeptical but omg i couldnt believe the instaneous difference....i drove home roughly twenty miles and i would normally grind 3 to 10 times....My car shifts like butter now with no grinds ....its pretty amazing!

why doesnt any one believe????

"oh no, fuck the stupid "bandaid fix" I'll take it to the dealer" just to find out that they fucked up your car even moar.

should I just do a drain/fill and add syncromesh? where is the best place to buy it? what are other good choices? I have an 04 auto TL with 140K on her.

Lots of good the hundreds of threads talking about how good it works are doing........

No, no, no. GMSFM fluid is for manual transmissions, NOT automatics. Don't even think about using this stuff in your automatic TL.

I used ACDelco, same stuff as GM haven't had an issue with grinding in 20k.

The GM fluid is still standing on my nightstand next to my bed, with new washers. I really need to get around to this.

Heres a recap....had the magic juice put in on tuesday....i would normally grind or get locked out of third atleast a few times a day...Its now friday and i have not grinded or felt the slightest bit of resistance when shifting in any gear especially third...This magic juice ftw!

lowchief, did you just call all the GM dealerships around you until you found some? what is the part # and how much did you get??

i know i know i should search to find these answers

lowchef

ya basically i first called my local cadillac dealer who directed me to my local buick dealer who had only 5 quarts sitting on the shelf....You only need three quarts....and there and $15.00 a piece...part number is #12377916 make sure its friction modified!
i think it took 2.5 quarts roughly.

thanks guys...did you drain the old fluid and put in the new fluid yourself or did you take it to a shop?

JORTS

the local Chevy dealership has it in stock! $14.08/qt...going to pickup 3 qts today..need advice on the install!!

I may be wrong, but I believe that AC Delco is just the rebadged Canadian version of the stuff. I did find up here that there are two types of Syncromesh. The dealer I went to had the wrong stuff (I think label didn't say Friction-Modified and it absolutely had the wrong part number).

The AC Delco part number is #10953509.

Here's the how to everyone: Looks straight forward.

I have 3 bottles of the friction modified waiting to be put in. I can't wait!

I wonder if it will work in my 3 series. I hate 2nd and 3rd gear grind. Experts please chime in.

Gentlemen;

A drain and fill takes 2.3 quarts (U.S.). That's two quarts, ten ounces rounded. Do NOT overfill.

Also, you do NOT need to remove a slew of stuff on the upper end. In fact, you don't need to remove anything at all if you have the proper tools to do the job. Not the battery or its plate, not the ribbed throttle body coupling, not the air cleaner upper housing cover.... nothing.

I was one of the members who did some extensive writeups on this procedure so you might want to search for those.
