So in my 1966 cj5 my t866 has been having some issues. Ive narrowed it down to the synchros being the issue, and I want to get all the info I can on them before I buy new ones. I found a synchro unit for sale a few days ago but i couldnt find them today. How many synchros are there in this tranny? Just first gear or? Would the 100 dollar synchro unit be all i need and if so does anyone know a good place to buy new ones?
