So, what kind of fluid should one use in his/her CLUTCH-type LSD. A co-worker of mine has purchased a 1st-gen B16A with a "mystery" CLUTCH-type LSD in it, so we're trying to figure out what the best fluid would be for the tranny.

I KNOW the stock Honda LSD works well with genuine Honda Manual Tranny Fluid, but it's not the clutch-type.

I don't really know what brand it is - probably Kaaz, but not sure. He tore the tranny apart and inspected the diff - the fluid that came out smelled very strange and was pretty think.

Any help would be appreciated.

 

80w90 gear oil.

 

Kaaz makes gear oil specifically for clutch-type LSD's.

 

I use Redline, primarily because they sponsor my car, but if I had to buy it would be Redline. Ask anyone that has seen me drive the car, the tranny has taken some serious abuse. The last time the tranny was broke down, all the parts were in excellent condition (no wear). My $.02's worth. I believe it is Redline MTL.
