I replaced my clutch, pressure plate, slave cylinder, and had my flywheel resurfaced. I bled my slave cylinder twice following Haynes instructions, and I'm still having problems which I don't even think stem from my new clutch.
I cannot shift gears at all, with the truck NOT running, or with the truck running. I have inspected the throw out bearing push against the pressure plate from underneath the truck through the inspection port under the bell housing, and I can see it move against the pressure plate.
But what really makes me curious is the fact that even when the truck is not running at all, I cannot shift out of neutral into any gear with or without pushing the clutch pedal down. This issue should not be connected to the clutch at all because the truck is not even on and I'm not even engaging or disengaging the clutch. It makes me feel as though there is now something wrong with my transmission, but it was fine before.
Here's another kicker! After I start the truck, if I take my foot off the clutch pedal, the truck stalls!
My guess would be that somehow the transmission input shaft (mainshaft) is jammed hard against the flywheel. Either due to a wrong pilot bearing or wrong/distorted clutch plate.
If it was me I would pull the transmission again and have a look.
