Wonder if anyones heard of it? I noe its made for heavy duty automatic turks. but can i use it in my tranny or lsd diff if i mix in solution wiht a thicker weight gear oil? has anyone every tried it? its supposed to help creat more friction so things work better. not sure about using it in the tranny but diffenately wanna try it in my LSD for my cressida.

Friction modifier doesn't increase friction. It keeps clutches from chattering in a limited slip, so I would actually guess it reduces friction.

 

Use regular gear oil with any LSD additive (friction modifier) or you can get some really expensive gear oil. Best stuff I've used is SWEPCO 201, doesn't require additive, and I use it straight in the diff and cut it 50/50 with ATF for quicker shifts in the transmission. Works great, about $40/gallon, you can find it in European parts stores and Porsche shops.

Here at work if we flush a transmission that has had accesive clutch wear and the transmission no longer has enough clutch material to keep the cluthes from slipping we add GM's Limited slip additive. It is a little 8oz bottle of friction modifier. I have seen first hand where a car couldn't even move from the bay "fixed". I do not however reccomend adding it to a heathy transmission to make it shift faster. It can be a bandaid for a failing transmission though.

That's bizarre. I've heard from many people over the years that if you put FORD friction modifier in it will make an LSD more aggressive. I always thought that was BS.

 

When I worked for Randy's R&P, I was told that it was all the same stuff, GM, Ford, Chrysler, makes no difference at all. We sold Ford stuff because it was the cheapest. I believe Randys, and I KNOW that it is used to reduce chatter, but maybe it doesn't actually reduce friction, just stiction, assuming that's even possible. Anyone who has driven a clutch style posi with no additive then added the friction modifier can tell you that it makes a big difference and that it reduces chatter which to me always implied that friction was being reduced. Maybe it has some other effect in transmissions that I'm not aware of.
