Just picked up and added to the collection of MJ’s with an 87 Comanche Chief. This truck is almost fully optioned out from factory with all the skid plates, Tow Mirrors, RollBar, Bedlight, 4wd 5spd, and Air conditioning. The body is 99% rust free, the plan now is to do a full day 1 restoration on this truck. Here’s a link to the guy I bought it from’s build thread

I've owned this truck for a couple years now, but never got around to posting, so here goes... This is Amelia, my 1988 SWB 4WD Pioneer. I picked her up in Tiger, GA with no visible rot and only minor surface rust. She had around 130k miles on the original 4.0 and BA10/5, and appeared to have sat under a tree for a while. Something special about this truck (that I found out months later) is that the original Vehicle Building Order page was still stuck to the inside of the driver's door panel. 30 years in Georgia humidity somehow weren't able to destroy it, and it's a special piece of this truck's history. Since purchasing, I've already changed, updated, and fixed a bunch of things, and will post some backdated updates as I have time. My goal is to restore to a factory-level, with small upgrades that I would have ordered if I bought this truck new off the line. In the meantime, I've enjoyed driving her around, playing in the garage, and researching what I'm planning to do.

Anyone have any tips or tricks for bleeding a new clutch system? This is on a Peugeot trans. I fear I may have blown out my brand new slave cylinder. Installed new clutch, master and slave the other day. Whenever I push the pedal in its dumping fluid out of the bottom of the clutch housing. Have a new slave on the way but don't want to pull the trans again if I don't have to. I filled the master with fluid and pushed the pedal in to fill the system, fluid went down and repeated then noticed it was pouring fluid out of the bottom. Not my first clutch but still new to manual trans maintenance. From what I have researched I feel like there was too much pressure in the lines and it blew the seal out of the slave cylinder. Thanks for any help.

I've just purchased my MJ a few days ago. I'm trying to figure out what transmission I have. My Comanche is an 88 and I've read that 88 was the year they started phasing out the ba10/5. I would check for the band that the ax15 is supposed to have but the MJ in question is several states away from me at the moment (long story). I know that the transmission in question has an internal slave cylinder (and it is broken). Is any transmission behind an inline 6, with an internal slave cylinder, ipso facto, a ba10/5? or could it be an early version of the ax15? how can I know for sure? Hypothetically, if I have a ba10/5 (which i am informed is trash garbage) just how bad are they? Ive read a lot that they are bad but why? (Id like to hear a horror story) Obviously I wouldn't want to sink money into a rebuild for it if it breaks outright, but right now it just needs a clutch kit with a new slave cylinder. Should I just save my money for a new ax15 instead of fixing this? (assuming its a ba10/5)

Hey guys, I got a problem on my hands with my 1989 MJ 4.0 2WD with the BA10/5 transmission. To start at the first of my problems, my clutch pedal started to feel soggy. I checked the fluid level and it was low, so I topped it off. A week or so later it was soggy again and low so I topped it off again. Doing this over and over I decided to check the master cylinder. It didnt look like it was leaking too bad but it was a little bit, so I changed that out and bled it. After I bled it, it felt great, but then after only driving it around the block it went soggy to zero pressure and then there was fluid leaking between the dust pan and tranny. So I figured it was the slave cylinder all along. I then dropped the transmission and replaced the slave cylinder, while I was in there I replaced the clutch and pressure plate as well. Now with everything back together and after bleeding the clutch I get good pressure, but when I start the engine and try to put it in gear it will not allow me to at all, and the clutch pressure starts to slowly fade away. After shutting the engine off it seems like the clutch pressure gradually builds up again. I then bled it again and then pushed in the clutch while I’m gear and had another person try moving the truck. It will not budge. I can hear the clutch moving a little bit by repeatedly pressing the clutch with the engine off. I tried bleeding it several other times and still the same issue occurs. The tranny shifts perfectly while the engine is off and it has fresh fluid. I am stumped on this one guys... as of this moment I am going to try leaving the reservoir cap off over night while the clutch is pressed all the way down to see if any air in the system can work it’s way out. I would really appreciate any of your guys help as I am trying to get this going as soon as possible. Thanks.

Finally joined the Comanche club a couple months ago. This is a 1988 4.0 5-speed 4x4 with 180k on the odo. Exactly, what I had been searching for... a shortbed, 4wd, manual with a 4.0. Currently, I am wrestling with some electrical gremlins and goblins. Learning Renix has been interesting, to say the least. Not on the road just yet but, once I am finished sorting out the wiring it should be good to go.

My transmission (BA10/5) is going out. I have a 87 Chief 4x4 5spd I6 4.0L I am restoring. If you could help me find a new used transmission to replace it with that would be the $#!&! Preferably the Ax-15 but Ill take anything that works right now.
