On a recent drive, my gearbox broke and i was fortunate to still have the 4th gear to get me home. I don't understand how this can be and not sure what is broken. Just before i lost my gears, there was high pitch/winding noise. Last year i rebuilt my engine and put new clutch in, but there was always a noise form the gearbox (not in 4th), which i assumed was my thrust bearing because everytime i de-clutched it went away.
Can anyone tell me what broke and whether i can fix it or why it broke. Any info would be a benefit
