Yes, Thats the symptom but only when fully hot with wheels off the ground, when clutch is depressed and in any gear, the output shaft still turnin the rear axle. It does not do this cold. Once I learned that the TKO 600 rev gear is not synchro'd. , when cold , if I select another gear before reverse, no more grinding into reverse, I get that part. The clutch disc now releases with pedal about 1 inch off the pedal stop. I must admit this testing is done with car elevated, no intertia load on drivetrain, have not yet go karted either.
