Transmission lsd ?

[mufflers of great justice]

Hey guys i need your thoughts on this. 

i dont know much about limited slip differentials or transmissions. however what i do know is that i hate the u660E transmission in the aurion. I stumbled across what claims to be a lsd conversion kit for our transmission.

That is probably the dodgiest "LSD conversion" I have ever seen. 

A bench grinder, seriously?

LSD a Front wheel drive, not good except for maybe the tyre manufacturers. Agree with Trent "bench grinder" that's dodgy as.

This is incorrect, there are muliple different types of LSD. The torsen LSD is nearly perfect for FWD vehicles due to the way it biases torque.

Is this one of those?

You had me 'til I saw the bench grinder. Jesus...

Sadly no. I was speaking generally, as you were. It's a clutch type setup and a poor example at that.

I'm a bit lost with this, clutch type LSD's generally require modified fluid otherwise they do not function as designed how would this be possible with WS auto fluid in the transmission.  Any suggestions?

It probably would not function well at all.

I read to the bench grinder bit too, and thought "wait, you're using a BENCH GRINDER to get the GRIP SURFACE ?!"  .  On the basis the insert uses spring pressure on the bearing surface, it would have to be very flat ....and the chances of getting that right with a bench grinder are somewhere between fat and slim....(yeah, an old joke of a mate of mine)

That's before ya even get to the oil and stuff... and wait, don't diffs have to be preloaded and all that stuff ? Or am I too old ....

The carrier bearings do. But they have no impact on the diff centre.
