Air in clutch?

I've done some searches but I'm still confused....before I pulled my tranny, the clutch seemed fine--now that everything is back together, It doesn't seem to disengage completely. I can get into gear, eventually, but it's not easy. The tranny is about 1000 miles old now, so the syncros should be broke in, I imagine. I've opened the bleeder on the slave cylinder and let it run---even pushed the slave piston back in by hand in case there was some air in there...nothing. Thing is, it worked before---do cylinders just go bad overnight? I don't mind buying a new setup--what I have appears to be factory mopar stuff, but I don't want to throw parts at it either. I've bled prolly a pint or so through it. Any thoughts?

If it is air in the clutch sometimes it is hard to get the air out. I use a vacume setup to bleed hyd systems. For really stuborn clutches I use a pressure bleeder. They work the best. I found it very hard to bleed a clutch with the pump and open the bleeder method. On one car I even had to reverse pressure bleed the system.
Good luck
Dean

The same thing happened to me. I pulled everything apart, measured everything - it all checked out OK. Peter at SBC said hydraulics before I dismantled everything but I'm a little hard headed so I checked it out myself. I tried replacing the slave cylinder with 2 different ones - no luck. I finally replaced the whole thing with a Dodge master/slave cylinder ($300.00 plus) and that pretty much solved my problems. When the temp is in the mid to upper 20s it gets a little hard to shift. I have found that plugging in helps - don't know why??? BTW I had no luck bleeding the system. Hope this helps.

Mine did the same thing, but I can't get it to shift into any gear while runnin. I hope I got the clutch in right. How hard would it be to take a system off of my 92 and put it on my 93?

When you pulled the trans, did you disconnect the line to the slave? If not you may have put something together wrong. Did you remove the clutch? Maybe the disc is in backwards. Did you grease up the pilot bearing or replace it? If you over greased it the excess grease will get all over the disc and hang it up, and will get grabby or chatter while letting out the clutch. Maybe when you were sliding in the trans the input shaft caught the fingers of the pressure plate and bent them. If you did remove the line to the slave, you probably have some air left in there.

Didn't remove the line to the slave. Some of the fingers were bent, how do i fix this and how much is it gonna cost. I put some oil on it, but it took about 45 minutes before the tranny was back in. Gonna have to get a tranny jack. Saw a lot on ebay for around $150. Will any tranny jack work? My driveway is a lil rough, will that matter?

The trans weighs less than 250 lbs, a 450 lb jack will be fine if it raises up high enough. Lay down a sheet of 3/4" plywood so you have a smooth surface, you don't want the jack to "trip" on a bump and fall over.

You will need to buy a new clutch cover. You can't straighten the fingers without re-tempering them.

Yo should also check out whatever you hit them with when you were assembling the transmission, and make sure that you didn't do any damage there.

Good luck with it.

The input shaft on the tranny. When you said "cover" do you mean the whold pressure plate? Might just buy another clutch, this one's only rated to tow under 8,000 lbs.

The old clutch has been sittin outside for several months. Is it gonna be worth messing with? Soon after I find a way to haul my 92 I can start parting it out. Mabye just take the pressure plate out of it. Would the 92's pressure plate work with an aftermarket clutch?
