I have a 500t and i am having issue with my clutch slipping/engaging when shifting and will pop out of gear. Small amount of oil in the case. (coffee can under her when she is parked) but i have cleaned and reassembled still having troubles. What are some next steps into fixing this issue? I am assuming the oil is playing a role in this just like the commandos, but i am not sure. Parts vendors that can supply some older single parts?
