93 ford z5 speed issues
i have a 93 1 on dually(4x4) that has a 460 5 sp that lately hase been a pain to shift into reverse and sometimes second then other times it would shift great.
Lately to get it to go into reverse you need the truck to be in 4low to engage fully but has been getting worse as sometimes you really cant get it into reverse unless it rolls back on its own.
i have noticed that sometimes while pushing snow into piles that with the clutch pedal depressed sometimes it doesnt want to release the gear.
I have put 2 new slave cylinders and master cylinders on the truck withing a year and a half. the last was 2 months ago and cant get anymore air out of the system.
also, when you start the truck in the mornings alot of times the starter will stay engaged until you release the pedal and sometimes it does it when you shift.
i have checked and the flywheel doesnt appear to be loose or cracked. the tranny is bolted tight to the motor, etc..
Could the shift forks be bad, as the truck runs in nuetral you can wobble the shifter around pretty good and in some of the gears too.
or what else could it be?

Hydraulic Clutch Troubleshooting .: Articles Have a read here. Also inspect the firewall for cracking/flexing where the master cyl bolts up.

i looked at mine and where the push arm that comes from the master cylinder and attached to the drop arm has the switch over it and doesnt appear to have a adjuster there. is one inside of the switch?
the firewall also appears to be free of cracks and stuff as the pedal drop arm and linkage appears to have no free play whe depressing it slowly.

also, as of now when i go to put it into reverse is while rattle the gear as i try to put it into reverse and will move the wheels backwards but acts as if its on touching the outside of the gear and not engaging as it wont go backwards but it did once without problems a little bit ago.

while it was nice out today i went ahead and unhooked the slave cylinder from the belhousing and noticed the clips that hold the fork onto the pivot ball are broken. Would this be my culprit not giving me full motion of the slave cylinder?

also i noticed that is the transfercase is in neutral it will go into reverse fine(but the truck wont move), if i press the clutch in and then put the transfercase into 2hi/4hi/4lo it will quickly jump out of gear and growl/grind at ya till you move the shifter away from reverse.

The throwout lever certainly could be a problem if bent/worn. With the slave cyl disconnected how much free play do you have a the end of it?
Also your description of trying to get reverse would maybe indicate that it is not fully shifting into reverse, either because of a worn shifter or worn reverse gears. If you put it into reverse with the engine off, then start the engine and release the clutch, does it stay in reverse and operate normally?

Make sure your clutch pedal assembly doesn't have any cracks in it. May be worth a few minutes to pull your instrument cluster out and check the dash to make sure it's not moving or broken. Also, if your bushings are shot where your master cylinder rod attaches to the pedal that could be your culprit as well.....To me, this doesn't sound like a slave cylinder or synchronizer issue, this sounds like a clutch not fully engaging/disengaging issue.

today i went ahead and started pulling the tranny out of the truck. after taking the transfercase out of the truck i decided to go ahead and try starting the truck and now it will start without the starter dragging and shifts fine into reverse but will pop out if your not resting your hand on the shifter.
could the transfercase be the culprit or is the tranny still the problem?

Update! after i got the tranny out i noticed all the springs inside the pressure plate were all laying inside loose and the clutch disc springs were all gone.
I know the pressure plate is junk and less than a year old(under 2,000miles), but would it be the culprit of the reverse or is the reverse gear going out to?

Well, you have certainly diagnosed the clutch problem!
However jumping out of reverse with no load is not good. Could be worn shifter or worn reverse gears or bad shaft bearings. I think I would pull the shifter and have a good look at everything.
There are some real ZF5 experts here and it might be worth starting another thread such as "ZF5 jumping out of reverse" and see if you get some expert response.

I don't think you'll be able to see much of anything just pulling the shifter. My ZF popped out of reverse when I first got it, so I pulled it and rebuilt it. When I tore it down, I found that the reverse gear had worn the thrust faces on the mainshaft and the 5/R synchro hub. It required a new 5/R synchro assembly, the reverse gear, and the mainshaft, but I also replaced the other synchro assemblies too while I had it apart.
