In order to give good access to the TCM, the vacuum reservoir assembly needs to be moved. A long phillips screwdriver will remove the two bolts holding the unit to the fender. Once this is complete the two 10mm nuts holding the TCM bracket to the inner fender need to be removed and the bracket can be unmounted to give better access to the TCM connector. The connector is removed with an 8mm socket (counter clockwise to loosen). After a few turns while the bolt feels like there is still resistance it helps to pry on the tabs with a flat screwdriver to make sure the connector is coming out evenly. It also helps to wiggle the connector and assist pulling it out a bit. After the connector feels loose, the bolt should be able to turn using the socket and your hand. Now remove the TCM and bracket from the vehicle and remove the bracket from the TCM (3 bolts). Installation is in the reverse order. Below is a link to several pictures detailing the removal process.

I would like to add that I was able to remove and reinstall the TCM with little effort, with simply a 10 mm x 3/8 drive socket, and a 3/8x8 inch 88 tooth ratchet (matco part number BFR88T) and a 8 mm nut driver, I did not have to loosen the vacuum reservoir. It took longer to clean the mud off of the TCM and connector than it did to remove. I did have to slightly bend the bracket lip (the part that slides in to the pocket) slightly outboard in order to reinstall it. There is just barely enough room for this process, not a millimeter to spare, I also had to remove the vacuum modulator/vgt controller and vacuum solenoid. (these are loosely mounted to the reservoir and easily removable by hand, no tools)

It is perhaps easier to remove the reservoir.

Keith just be aware that the TCM location on export right hand drive KJ CRDs is on the other side of the vehicle and mounted on the firewall near the ECU. From what I can tell by looking with my little mirror it is going to be impossible to remove without some major effort (the AC canister is right in front of it).

Reaching the 2 vacuum assembly phillips screws (note they also have a hex head but I forget the size) as noted requires a really long #2 phillips screwdriver AND it's best if the screwdriver has a magnetic tip as the screws are way hard to reach to remove or install. Better yet is to remove the bottom of the air cleaner box before trying to remove the vacuum assembly. Simply pop the air box top clips, remove filter, detach the 2 electrical connections (1 has a sliding clip and the other has a tab retainer that need attention before they will unplug) and the turbo hose from the air box top and set the top to one side, the bottom is held in place by 3 plastic plugs (much like those that secure the plastic engine cover) the reverse of which can be seen in the 3 indentations in the inside bottom of the air box. I found removal of the air box requires a rather firm bit of tugging and wiggling "up" from the left rear (closest to the TCM) to release the first plug and then the other 2 pop loose fairly easily. After the air box is removed the vacuum assembly is a piece of cake. Reinstall in reverse order (TCM, vacuum assembly, and finally the air box bottom). Note that the rubber pieces the air box plugs fit into may come out when you remove the air box in which case you have to put them back in place and also that replugging the air box bottom in place requires about 5 minutes off wiggle, feel, fit before it can be pressed into proper place but it's well worth the effort.

Be sure to plug the turbo hose to keep debris out on the turbo while the TCM is off being flashed.

I have managed to get the TCM installed in the right hand drive export model. Anyone wanting TCM install instructions for the right hand drive export models please contact me through Private Message on Aus Jeep Offroad (AJOR) or LOST, and I will send you a copy of the RHD install procedure (It is different).
