I sent my tick master cylinder out to be replaced because fluid was leaking out the boot. A few weeks later my new master cylinder is doing the same thing. Anyone else have this problem?

My t56 has been having clutch issues since I did the swap. My trans grinds into third and fourth and sometimes doesn't lock into second. If I shift at low rpms I don't get any grind and the trans goes right into gear. Its been driving much better since getting the new master but now I notice its leaking again. I think the shifting issue is just air in the hydraulics but I'm not sure if the master needs to be replaced again

 

Make sure the pushrod is strait when going into the master. Most 3rd gens require dimpling of the fenderwell to clear the master for this

 

It looks like my pushrod is on a slight angle but I'm having trouble getting the seam on the fenderwell to dimple in enough to get it straight. How close does it have to be?
