G50 and NEWER (1987-On including GT2, GT3 and Turbo)
Anytime you change the gearbox oil in a G50 equipped car we have found where the G50 gearboxes are ultra-sensitive to the Driven GO gear oil.
It can cause rough shifting and synchronizer operational issues.
Do not put Driven GO gear oil into a G50 gearbox!
