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

It is in the axle and the gears are turning. No noises, thumping, or cracking, so it must be working.

Works great. Took the chatter away from the clutch pack.

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.

Makes slippery things slipperier

This trans-x limited slip additive works very, very well in place of factory additives/modifiers. I had put this fluid in my 04 Chevy Express 3500 with the big ole 14 bolt rear end, and all the chattering that was going on was taken care of after throwing this stuff in during a fluid change. Its very well priced and seems to work just as well as comparable OEM fluids.

Only need 1 tube & no chatter

Diff sounds good

Easy to get into rear diff with the package design

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

trans-x posi track additive have used this for years with no bad results
