A few weeks ago my Lemans got stuck in 2nd gear….oem shift spring failure. I replaced the spring with the Chuck & Scud Super Duper Indestructible Spring. While I was in there, I also replaced the detent roller with a 688-2Z bearing (per Docc’s recommendation, I think) purchased from McMaster-Carr, they’re local to me. Polished the selector shaft, checked preselector plate, boss and cam clearance. Now I’m just waiting on a new shift shaft seal. Big thanks to those guys and the rest of you guys that contributed to the Shift Improvement thread and Re-Engineering the Shift Spring threads. Thank you!
So, the oem shift selector spring broke, after getting the selector plate off the trans I immediately replaced the spring with the Chuck & Scud Super Duper Indestructible spring (barely seen in photo). I then stopped and re-read the Shift Improvement thread and Re-Engineering the Shift Spring threads. After reading the threads again, I was more comfortable taking the assembly apart, washing, inspecting and doing the needful indicated in the threads.
