I have few quick questions about the g20t's lsd 1) when changing the tranny fluid, do i need add a friction modifier? 2) does the g20t have a sealed lsd like the se-r lsd? 3) i have hearing bad gear winding noise, i am hoping changing the tranny fluid fixes it. if it doesn't, any other suggestions?
