Please help w/ Tranny problem
I have a 1984 F250 2 wheel drive with a 460 and a 4 speed tranny and i am having some troubles with the tranny if its cold its semi hard to get it to go into gear, and when it heats up its almost impossible. i cant figure out what is wrong with it, i can see the clutch fork moving the pressure plate when i take off the boot, it has a new clutch kit with only 5000 miles on it. Also i checked the fluid and when i put some in it worked great for about ten min. but when i checked it agian it wasnt low but it had air bubbles in it, any help is appriciated thanks. Also when i go into reverse it grinds.

If you saw air bubbles in the fluid, it means you have air in the lines and it's not letting the clutch fully engage. The fork will still move and engage the clutch a little, but not all they way and that causes the tranny to grind. The only fix is to bleed the system just like you'd do for brakes. The problem is finding out where the air is getting in the system. I'd start at the slave cylinder and look that over really good because it sounds like your troubles are there.

Not trying to be a smart a here, but this does need correcting - The clutch is always engaged. Air in the lines would not let the clutch dis-engage fully thus causing the grinding. Fluid pressure in this case thus causes a dis-engagement
Exact opposite of brakes which are nomally dis-engaged and thus required fluid pressure to engage. (or if you go way back, rods / cable / levers)
Good advice on the rest as far as looking for a cause of why the air is getting in there in the first place.
