Repaired my transmission not too long ago. Just the other day it left me stranded on the road. After paying an arm and a leg for a tow my mechanic told me there was a problem with the tail of the transmission.
I'm not very familiar with the working of said tail (output shaft in English?) But he did say some of the synchronizers were broken. Could anyone explain to me what those do and why those could break? None of my mechanic friends have been able to figure it out. Thanks a lot in advance.
The transmission is an Eaton fuller regular 10 speed and the truck is a 95 fld 120
Below is a picture of the broken part.
