Hey all. Im going to be fitting my newly rebuilt CZM gearbox (with Wavetrac diff) on saturday. Ive been reading stories about some Gear oils coming with additives, that i dont want with a wavetrac! I was going to use Motul 300 75w90 (the non LSD stuff). Wavetrac recommend using whatever the OEM oil is. I've no idea what VW would have used in an early mk4 golf gearbox. Anyone here have a similar setup. If so what oil do you use, and has it been ok shifting from cold etc. thanks Richie K
