Destroyed shift fork after 500 miles. Ideas?
I just tore down my gearbox after having it rebuilt, and then losing third gear within about 500 miles.
Upon teardown I discovered that the shift fork has .107" play in the hub and has machined quite a bit of itself away. 3rd gear synchro seemed to be fine, not bottomed out and still giving good braking. Thrust measurements were .021 for 3rd and .026 for 4th. What would cause this level of shifter fork wear in this little time?
I am using the car for TT so I am driving it hard, but my average shift time is still pretty high per data, and I don't drive around with my hand on the shifter. What else should I look at here before I put it back together and potentially have the same problem?
