Re: 86 4 spd won’t shift

The squarebody hydraulic clutches were a pain in the neck to bleed out.
You can do it with just the slave off. Tip the slave to put the bleeder at the top and push the slave plunger in and out.

The new parts quality was poo in the late 1990's. I went through five new master cylinders and more slave cylinders before I got one that didn't leak on my 1985 C10.
