Transfer Case

[$howtime456]

Just a heads up for those pushing 70k+ on there gran coupe. Be aware of transfer cases. Been researching on all the forums and it seems these are the weak points on 640s, 550s, 4 series, etc. depending on the mileage and maintenence. Was very surprised that even ECS tuning has a repair kit. If your car is modded or just good old stock, if these go they are very expensive from the dealer. (3k+). The good news is they are alot going around used and 2,3,4,5,6,7 series all fit. Mines just went and shot a hold through the case. In for repairs tommorrow.

is there a transfer case fluid kit available for the 6 series? I don’t see one listed as compatible on any of the parts sites.
