have anyone tried upgrading the transmission on the prefacelift
after having the car for a few months I think if there was one thing to upgrade it would be the transmission
does the auto gearbox have a non locking type torque converter? (it feels like it does but doesnt make much sense for such a powerful car)
could that be the weak point of the transmission
has anyone upgraded it? how is the result?

Weistec has a TC, it upgrades the stall.

A few guys did it, one broke his axles at the track.

I believe it locks when in manual mode.
