Hi all, I just got my first Comanche a few months ago and it's been an awesome truck for me so far. Until the other day I started her up and the clutch went down to the floor, and I could barely change gears. I checked my reservoir and it was dry, so I topped it off hoping that would do the trick. Nothing. I did some research online (including this site) and figured out it's probably one of the cylinders that went bad. The problem is I'm not sure which one. I'm really hoping it's the master, because unfortunately my truck has the dreaded internal slave cylinder, and I don't have the knowledge or tools to drop the transmission myself. Thing is, there's no visible leaking at either cylinder, so I'm completely lost as to which one I should replace. At this point I'm thinking of just doing the master myself, and if that doesn't fix the problem then I'll take her into a shop. But I would love to spare myself the trouble and cost of replacing parts that don't need replacing.... Any help would be greatly appreciated!! Cary

Hey guys, so I drive a 87 comanche 4x4 4.0L. It originally ran the peugot transmission and I never had any issues with the clutch in that, I was just eager to swap it and now have a NV3500 transmission in place. The master cylinder I am using is as far as I can tell meant for the comanche, http://www.autozone.com/drivetrain/clutch-master-cylinder/duralast-clutch-master-cylinder/jeep/comanche-4wd/1987/6-cylinders-m-4-0l-fi/69675_0_0/ The slave cylinder I use I believe is for a 2000 jeep cherokee 4.0L 4wd. I use a braided hose to connect the two. http://www.autozone.com/drivetrain/clutch-slave-cylinder/duralast-clutch-slave-cylinder/jeep/cherokee-4wd/2000/6-cylinders-s-4-0l-mfi/577903_0_0/ Finally to my issue! I have swapped out 4 slave cylinders and 2 master cylinders ever since I did the swap. Is there something wrong with my setup or does autozone just provide crap parts? Please help asap I need a new master cylinder cap and I know they're gonna make me by the whole master not just a cap. **Note** Just so you know if i'm doing anything wrong. I install my slave typically with the retaining straps still on and then I let the pressure break those straps on their own, maybe this is the wrong way to install? Also there is no bleeder valve on the slave and I've read a lot, seems like everyone just pumps the pedal to eternity and I did the same to bleed the system, seems to work for a little while atleast
