I just got a gsr tranny with a phanton grip LSD. How do I know it has lsd? Thanks

 

You will be able to see through the differential. On non-LSD trannies, there is a bar that runs across that partially obstructs your view.

 

Yeah that's how I can tell as well. The bar is there BUT both tire marks are left every single time I burn out. Hummmm

 

The bar means that it isn't LSD.

 

Phantom grips are... not really LSDs as I understand them... Basically they're just something that clamps and forces the driveshafts to move together. They're POSs and I would remove a phantom grip LSD before it causes something to fail. Get a real heilical LSD

 

We don't call them Phantom Slip Limited Grips for no reason...

 

Clutch units are good too.
