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

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

Many vehicles need this, check if your project requires it. I use it when necessary and it is a great additive.

works well, no chatter .

Only need 1 tube & no chatter

Even though I used GL-5 LS (limited slip) oil when I changed the rear differential oil in my Toyota Tacoma, it only took one short ride after replacing the old OEM differential oil to determine that something was not right. I heard noises and found that the rear wheels were locking up on sharp turns. So I parked my truck and did not drive it until I determined what was happening. After a fair amount of on-line research, I discovered that this additive is required even if the specified GL-5 LS is used. Concerned if this really would actually resolve the issue, I siphoned out about 7 ounces of the GL-5 LS oil and added Trans-X Posi Trac to the differential. Took my truck for a drive and the difference was noticeable after about 10 minutes. It does what its supposed to do. Live and learn.

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

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

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.

Works great for my Detroit Locker
