BigRedMJ89 Posted February 2, 2020 Share Posted February 2, 2020 Just bought my first 89 4.0 Comanche with the ax15 that’s shot I’m sure.. what auto trans can I convert over?.. & what all will I need beside trans,Tcase, drive shaft. ( I live downtown Houston,. Having a standard vehicle is a pain in the traffic ) Link to comment Share on other sites More sharing options...
Eagle Posted February 2, 2020 Share Posted February 2, 2020 AW4 You will need the transmission computer (TCU), wiring harness, kickdown cable, and possibly one or two other things I'm drawing a blank on at the moment. Oh -- and you'll need a shifter. The MJ would have had a column shifter. IMHO, it's much easier to get the floor shifter out of a Cherokee.

Almost better to pull from a Donor Xj wouldn’t u say... if so what years would I be looking for?. Donor Comanches.

What years were they column shifters? Link to comment Share on other sites More sharing options...

Quote if so what years would I be looking for?. Donor Comanches. Are a rare find in Texas You have an '89. That's in the series we call "Renix." You should look for an 87 - 90 XJ Cherokee.

Pete M Posted February 3, 2020 Share Posted February 3, 2020 the link in my sig has links for all sorts of swapping info. and just a point of clarification to what Eagle said, all years of MJ could come with either floor or column shift. both options were available.

omega_rugal Posted February 3, 2020 Share Posted February 3, 2020 can´t you take the column shifter from a S10? Link to comment Share on other sites More sharing options...

The steering column is the same -- GM Saginaw -- but the cable connection to the transmission might be different. And you won't have the instrument cluster with the PRNDL window. Don (Hornbrod) had his set up with an aftermarket PRNDL in a tombstone mounted directly onto the steering column, so there are ways to do it. My opinion only -- it's a LOT less work to just get an XJ floor shirter and use that. No need to change the steering column, no cables to run, no PRNDL to worry about.

Unless you have a love or need for the bench seat/middle seat, or you really like being able to shift from forwards to reverse without removing your hand from the wheel.

Minuit Posted February 3, 2020 Share Posted February 3, 2020 You still have cables to deal with on the floor shifter. At the bare minimum, the shift cable itself runs from the shifter, to the driver side of the transmission tunnel (the hole may or may not be already there - it was on my 91), then around to the transmission. For a column shifter, the hole for the cable is located in the very top left of the firewall. If you want to do it right, there is also a park interlock cable that runs from the shifter to the left side of the steering column. I can't say for sure, but I give it a 99.99% chance that there is no provision for this on the manual transmission column in his truck. This will result in being able to shift the trans out of park without the ignition being turned on, and being able to take the key out with the transmission in gear. This is all handled inside the column on a column-shift column. I like the floor shifter and bucket seats a million times better, but it's a toss up if it's any easier than swapping to a column shifter. Link to comment Share on other sites More sharing options...

Get a column shift steering column out of an S-10, and you get the other parts for an S-10 with a GM engine and tranny, not for a Jeep MJ.

This is all handled inside the column on a column-shift column. The manual tranny steering column has the steering wheel lock built into the column. It doesn't need any connection to the transmission or to the floor shifter. Just don't use the Park interlock.

The bench seat works with the manual transmissions and the mini console. The XJ floor shifter is no different in how much space it occupies -- it fits the same mini console.
