GM Synchromesh - Friction Modified used on JDM s80 (gsr lsd)

soo, tranny ran a little low on fluid and ever since then everything has been a little rough. Tried chaning the fluid like 3 times, no change..

i talked to one of the high-performance mechanics at a dealership and asked told him about my problem and he said to use this stuff and get the friction modified. he said it should help refurbish the gears and he's had it work wonders for customers before.

Put it in yesterday. Holy ****. It made a huge difference. Every gear goes in better and the more and more i drive it it keeps getting a little better so far. I would recommend this to anyone. I am going to keep running with it and see how it goes.

also, how do you go about doing this.

i have heard like 80,000 - 100,000 km or so.

you just lift up the car, unscrew the drain plug at the bottom of the tranny. then, the easy way is to take off the check plug on the side of the tranny. you have to do this under the hood and your intake may be in the way... but just put a tube and funnel and start filling. i believe gsrs are around 2.2L to full, but you know you are full when it starts coming out of the drain plug.

I'll do it for you or help you if you need it.

yeah, use the drain plug at the bottom to drain it.... then plug it back up... then, there is a check plug on the side of the tranny facing toward the passenger side fender... you take it out aand fill through there. once its full it will pour out. then, put the check plug back into it... and there you go.


and its not a problem, i would be more than happy to help you out. let me know a time thats good for you and i will check my work schedule... we need 15-20 mins tops.

This **** once again proved itself for me. I was on the track yesterday and shifting was fabulous.

Once a year should be good enough. If you race hard, 10,000km or do it every second oil change.

Some people change regular Honda MTF at every oil change.

What the hell!

I called Queenston Chev Olds on hwy 20. 800ml bottle is 9 bucks

They say there is no such thing as gm syncromesh "friction modified"


Am i supposed to use it straight just the little bottles or use gm sycromesh fluid, then add the friction modified bottles?

I need to know cuz im doing my swap tonight

yeah, thats the same thing i got from a few dealerships. I think just regular GM synchromesh would be fine, but the friction modified was better for my purposed...

you just need the part number. call, the hawley cadillac and ask for the parts guy, he should remember me coming in... just tell him if he remembers some guy who came in, asked for it.... and then they sent him to another dealership, who then sent me right back... hahha, they have like 10 bottles left when i was there. it was 14.90/litre

use straight modified?

I got 2 litres of Synchromesh Trans Fluid (14.40)
114ml of Friction Modified Additive (6.49)

After tax It came to 22.14


I told thew guy about hawley bbut He didnt belive me. He says they only sell the small bottles

Meh. I guess the lil bottle is concentrated to mix with the synchromesh ****.

I guess I see hopw it goes, i cant see it being worse that honda mtx
