Zf trans hard to shift
I got a 92 F350 with a 7.3 n/a and manual trans. My truck is really hard to put into 1st 2nd and 3rd gear and also even 4th sometimes. also grinds or doesnt go fully into reverse when I use it. I have no clutch slippage but a buddy told me it seems like my cutch is worn. Any ideas as to whats wrong with the trans so I can get an idea as to how much Im gonna have to save up for to fix it since my college seems to want every penny I have lol?

Is your clutch master cyclinder full of fluid? When you check it be sure to remove he rubber cup under the lid. If it is low it takes brake fluid. It sounds like the clutch is not disingaugeing when you depress the clutch peddle. Also check to see if you have any firewall flex when you depress the clutch peddle. Just a couple of easy places to check.
That said, not fully going into reverse sounds like the syncros or shifting forks are getting worn.

How much clutch pedal do you have does it feel like it always had, after checking what farmert said get under it and have someone depress the clutch while watching the amount the cylinder extend and make sure the tranny isn't moving back it just takes a hair movement in the tranny. I have also seen enough slack in the pedal assembly to cause this.

The pedal feels the same as it aways did. The clutch begins to disengage as soon as I step on the pedal. Im wondering if its the clutch tho because the clutch doesn't begin to engage untill I get about halfway off the clutch. Im gonna check these things out this afternoon when I get home.

I think I found the problem. The plastic piece that goes on the rod that connects to the slave cylinder rod basically broke apart and is almost non existent. the part that the slave cylinder rod connects to is also extremely worn out and is causing the clutch to not dissengage all the way. I stuck a piece of card board folded up in there to last. It seems to be working a lot easier now. Hopefully itll hold till the weekend so I can get to the junk yard and find a replacement. Do I need to find a specific diesel or is this the kind of part that i can pull of a gas ford and itll fit too?

Mine had similar problems, I replaced the master and slave shortly after I bought it, didn't do hardly a thing to help. Kept getting worse for two years, also my pedal effort was ridiculous! When I swapped my 4WD tranny in, I found the pilot bearing was completly shot, and the throwout bearing was dragging along the quill. My clutch would disengage completely, but the pilot bearing was causing the input shaft to still spin and it would always grind going into reverse, and I could tell it was really using the syncros for the other gears, even when it shouldn't have been.
That little plastic bit on the end of the slave cylinder doesn't really do much, its supposed to "lubricate" between the rod and the clutch fork. For how thin it is, it shouldn't affect clutch travel much at all, but that could be enough to make a difference, especially if other parts are worn as well.

I got another piece today from the local yard. They told me its called a Z bar. Im just having a real hard time getting to the nut on the clutch pedal side. I have it half loosened but it took almost 3 hours due to only being able to turn it in 1/8 inch increments. Any hints to get this nut off faster?

Nice work sticking with it. Sometimes that under the dash work can just wear a guy out.

Great When I was running my shop I had a hard time convincing customers that the pedal assembly was the problem. It does not take a lot of slack combined between the pedal assembly and push rod to mess with your clutch big time.
