Just finished rebuilding a noisy transmission. The gears and syncro's were fine, two bearings just had the race's, it got quiet when that happened (it had been noisy for a long time). We DIDN'T get our rebuild kit from one of ZW vendors, & I was not impressed with that kit. No instructions or even same bearings. Get your kit from ZW vendor. Take photo's of open case to refresh memory. It is not difficult.
Installing Transmission this weekend.
