K&W 402508 Trans-X Posi Trac Limited Slip Gear Oil Additive - 7 Fl Oz

Great product for stopping or at least slowing shakes and shimmies in the transition.

good product

Application: 1982 Mazda pickup (manual transmission) that was hard to shift from first to second when cold. This more sllippery gear oil has improved the ease of shifting. The hard-to-shift-when-cold probllem was long standing and had been cured before with a similar product. In my last transmission oil change, the mechanic did not add a limited slip gear oil, and the problem came back. Adding this oil to the tranny resolved the problem.

I had to replace all of the side gears, spider gears and clutch packs in my 8.8 Ford Trak-Lok. On opening the box I was worried about this products validity, as it did not smell like a rotting half dead cats peed in the box. The stuff from Ford typically does smell wicked awful. I went ahead and used it to soak the clutch plates ahead of time, and then added the rest of the tube to the gear oil as it went into the differential housing. It seems to work fine, the rearend has not chirped, clunked or barked a tire since.

Followed the directions and no issues here with my 2006 Toyota Tundra

I picked this up in a pinch for my 2008 Ford Mustang GT when I was changing our the rear end gears. I couldnt get my hands on the Ford friction modifier, so I picked up a tube of this instead. I was a little skeptical because I knew nothing about it. However, is been two weeks since I put this in my differential, and everything has been just fine. I dont get any chatter from the limited slip differential. Everything feels normal with the car. I would use this again.

I don’t like the way the bottle is shaped, I had to use some tools I had around the house to get the tube in the rear dif hole 2011 camaro ss rs The sound from the rear differential is slowly going away after just 20 minutes I will update if I real care but so far so good I hope it works like the comments Next day the chatter has went down a lot !!! I would say this work just it completely hasn’t went away so now I think I have some other type of damage in my dif but yeah I’m happy

I use this and 3 quarts of Mobil1 75w90 LS gear oil in my 2002 Tundra. Without this additive, the LS clutches will chatter.

Works great for my Detroit Locker
