Hub and sliders are replaced on any rebuild through us. Most tranny shops skip this very important part. The hub and slider will make or break the quality of a shift. The pic below is of a slider that is worn. Note the teeth at the top are rounded off and worn out. They are supposed to have a clean sharp edge. This will make the synchro blocker ‘slip’ and make the tranny grind when shifting at high RPM. It will also give a ‘notchy’ feel:
This next pic is of the hub. This unit has what is called chatter wear. This gives the tranny a notchy feel as well:
We also replace all the keys and springs. When you get a tranny from us, you are literally getting all new synchro parts. Everything that makes the synchro work is brand new!
