I recently broke my shift fork in my tranny. My friend has an archer brothers transmission. Does anyone know anything out them?Or if its just a stock transmission?

From what I've been told all the "built" transmissions are made of machined OEM mitsubishi parts. None of them are "stronger" than stock stuff is if you built it in your own garage.

Buy a new shift fork and be done with it if you didn't torch all kinds of other stuff inside your slush box.
