87 Bronco II with FM145 Difficulty Shifting Into Gear

[Segagee]

Hello all, new member from South Carolina here. Just purchased a 1987 Bronco II with the Mitsubishi FM145 manual trans on the cheap a few weeks ago. The truck initially had no clutch pedal (all the way to floor), but replacing the slave cylinder fixed this problem. Clutch pedal is fine now and the clutch seems to be disengaging properly when taking off. The problem is, however, I have difficulty shifting the truck into ANY gear while moving and have to pump the clutch in order to shift, and it is still very difficult to do so. The trans had fluid in it (90w gear oil), but I flushed it and replaced, which seemed to help the rough shifting only very slightly. I have also tried bleeding the system/clutch master cylinder from behind the pedal as well as the bleeder valve on the tranny. Neither has helped, and I am assuming the system is bled properly because there is no sponginess in the clutch pedal.

I have yet to replace the clutch master cylinder, but given I have a solid clutch pedal I'm not sure how to test if it "bad" or on it's way out or not. It is not leaking. Is it possible master cylinder could cause the difficult shifting? Just looking for some basic info before I have to tear into the tranny itself. I would be kind of surprised if the tranny itself was bad or all of the gear syncrhos went out at the same time. Not really sure how durable these FM145's are.

Thanks in advance for any help/advice.

Admins if this is supposed to go under the "Bronco II Specific" forum instead of the "transmissions" one please move it and let me know for next time. I am also aware of the BroncoII Corral website, however, these forums seem to get much more traffic.
