Yeah, I'd say you already got your money's worth. 200K on the original transmission.

Because of the age/mileage of the vehicle only you can determine if its worth it to repair. We don't know your situation on transportation or your priorities.

Research the cost difference between just replacing it with a used tranny vs a rebuild - assuming that a remanufactured is cost prohibitive.

If you've already replaced/serviced many parts along the way, it might be worth replacing/repairing the tranny and keeping the vehicle.
