You are already there; If anything is floating inside because of this problem, it has already doing damage. Don't go very far without 'AAA' coverage.
Forward gears shift great yet, sounds like I will lose reverse at some point and it might damage everything right ? I will have to make the decision to fix or sell for parts as the car has close to 300,000 kms
Time to make plans.
