6G Celicas Forums

Well i have a complete engine and tranny from an 1998 jdm non-beams blmzf 6gen celica.
I'm pretty sure that it has an lsd tranny (s54-06d) with it but i can't decide that it's a viscous or it's a helical lsd.
I have an st182 and i bought this engine just for backup. It happened that my original st182 tranny gave up (bearing sound) so i decided just to use the tranny from the st202 engine (my original st182 3s-ge is working flawlessly).
The LSD is there i'm sure about it, the wheel spinning (full throttle in first gear and steering full left and right) test is indicating this, although the cornering behaviour is totally different from the original st182 gearbox so the LSD is definitely there. What i can not figure out is the type of the LSD. Helical or Viscous ? I wants to know it just because of the oil type, i want to use the best oil for the gearbox.
Could you help me out at this ?
