I had a leaky shifter input shaft seal just repaired recently. No mechanical problems with the tranny other than what was mentioned. Its lasted that long and everything is fine, buy it. It doesn't hurt to have evrything inspected. Ask when all fluids have been changed. I would change them anyway. Who knows what the previous owners habits were when it came to service. Buying anything used, you always have risks. You should be able to research all the service records at any dealership to give you piece of mind.
