@Thomas @Guardian it could be argued that jeep cherokee's break down less often than tanks lol.

but I will say that the transmission issues are actually fairly straightforward.

owing to the modularity of components (more so than a lot of vehicles I've found actually...).
it literally is just a matter of putting a jack underneath the transmission, unbolting it from the engine, various hoses, the drive shafts, and the shift lever, and then swapping it, install in reverse to how you put it in.

theoretically it can be done by one person but it's far easier with two.

Torque converter transmission

It would be much better for two just because of the weight of the gearbox. Have you also thought of a new converter? If you were to remove the gearbox some screws would be required. Often it is not the transmission, but the converter, I remember manufacturers say that transmission oil lasts a lifetime, but that is not true, according to the transmission manufacturer ZF, says transmission oil change every 80,000 - 100,000 t km and "converter" I don't know 99% of 180,000 t km is defective whether that is the right word for torque converter gearbox

A picture is worth a thousand words :-)
