here is how i bleed the system, which has always worked well for me:

- remove the clutch fluid reservoir cover.

- using a small punch, knock the roll pin out of the slave cylinder and pull the hydraulic line out of it. inspect the o-ring for damage.

- unbolt the slave cylinder from the transmission (2 13mm nuts). you will need to depress those two small plastic tabs to remove it completely.

- holding the slave cylinder at a 45* angle, slowly fill it with DOT-3 brake fluid. when it's almost completely full, hold it at a 90* angle and fill it completely. set the slave cylinder aside keeping it upright so no fluid leaks out.

- fill a small clear container with new clean DOT-3 brake fluid. fill it enough so that you can submerge the end of the line in the fluid.

- have a friend *slowly* pump the clutch pedal. you should see dirty fluid and air bubbles come out of the end of the line. make sure you keep the reservoir topped off with new clean DOT-3 brake fluid while you do this to keep air from re-entering the system.

- after the air bubbles stop coming out of the end of the line, have your friend keep the clutch pedal to the floor while you pull the end of the line out of the clear container and insert it back into the slave cylinder.

- keeping the clutch pedal to the floor, push the roll pin back into the slave cylinder so the line stays attatched.

- top off the reservoir and try it out

hope this helps!

Definately use Synchromesh, it enabled me to have a 2nd gear still even when I blew out the synchro at the track.

the Getrag 5-speed in my Turbo Dodge calls for 5w30 motor oil....i wonder how it would like GM Syncromesh? it shifts great with 5w30....hmmm....

(i've only used GM Syncromesh with my 282s but $10/quart....jeez)

for my clutch to bleed it i vacuum bleed the system (mine has no bleed screw)

Could you go into some detail on vacuum bleeding? I recently replaced the clutch on my 282 and when I reinstalled the slave cylinder (the newer external style) and pressed the clutch pedal it just kinda flopped to the floor and stayed there. Feels like there is loads of air in it. I removed the slave and bottomed it out by hand. I put most of my weight on the pintle and had someone press the clutch. The slave pushed me up about a 1/4" and no more. The pedal in the car feels dead. There is no resistance on it. I'm not sure how air got into the system or even if air is the problem. I did neglect to support the clutch pedal while the slave was out of the trans case and the plastic straps that retain the pintle were broken so it went to its full extent. Does this seem like a sign of a malfunctioned slave or master cylinder or air in the system? The resovoir is full and there are no leaks. It is not even damp by the clutch pedal. Don't mean to hijack the post... just looking for more info and I'd like to try to bleed it first, but there are no bleeder screws. I've successfully bled the hydrolic system in my 284 by repeatedly compressing the slave cylinder until it bottoms out with the resovoir cap removed. This method is not working on my 282 system.

Thanks,
John

that wouldn't cause a problem nor would have allowed air into the system. when i had my s/c removed mine fully extended also. bleeding the clutch hydraulic system is easy...way easier than bleeding brakes. you need to remove the hydraulic line from the slave cylinder to bleed it.

to vacuum bleed buy a Vacuum Pump, you'll also need an old clutch resevoir cap to modify or use a special vacuum bleeder rubber seal piece... hard to explain. to bleed the clutch you need something that seals off the top of the resevoir so that it can suck the air out of the system.

you can take an old cap, drill a hole in it and intall and seal up a vacuum line fitting through the cap to use the vacuum pump with, or you can buy a large rubber piece that has a steel tube that goes through as well.

i have a Blue Point vacuum pump kit.

if the slave cylender rod is all the way out does it need to be bled? , i just put my trans back and my clutch pedal is really soft, do i need to bleed it? why is it soft?
