Transmission is from a late 90's (E36) M3. I'm partial to Redline MTL, personally. Redline's site recommends D4 ATF for the application, but I despise the idea of putting ATF in a manual gearbox. Simply doesn't protect the synchro's. I see some people are running Royal Purple SynchroMesh, but I've enver trusted RP products. IMO, just like Mobil 1 - overstated, and underperforming. FYI, factory recommended fill is BMW's MTF-LT2.
So. Any recommendations? Doesn't need to be long life, it'll get changed every 30k tops. Thanks!!
