Its the same auto as the Jeep and a lot of Toyotas. Very few actual breakages but all the usual things about autos applie ie extra cooling, dont let water in etc.
Swapping auto to manual is a painful exercise but can be done. If your cheap rockcrawler is a second hilux transfer case you can also do this to the manual.
lower gears result in less strain on the engine and trans but 37 inch tyres will even this out.
Why do you want such big tyres

How are they done? If they work well and the price is right he might be able to make a few sales

The only issue I've ever had with the Auto off-road is how far it hangs down. The same model MU with a manual box has a lot more clearance.

I had a auto and it was great for off road as Nick said it hangs down bloody low. I did put a manual in mine and it was the best and easiest mod I have done, everything bolts up perfectly and it uses the same amount of fuel running my 33's as it did with my 31's with my auto.
If you are worried about loosing your crawling ability when in 4wd then just put some low ratio diffs in (assuming you have put lux axles in) like 5.29 which I think brings it back to standard gearing with 37's.

Im running 4.88 lux diffs, i cant change these because im using a LJ71 High Pinion front diff  my crawl ration is good atm, on 33s i think i scored a Mu 2day for cheap, its too good to chop up (110kms on speedo) everything feels real tight like the locks and handles, hinges etc ;D after getting the quote on 37s iv decided on 35s, hell of a lot cheaper, Now heres a question!! the mu body im looking at is a auto, will my manuel still be ok etc, how hard is changing the pedal box and fitting mastercyl?? |

The manual bolts in piece a piss. Un-bolt the auto trans ecu and take of the little cover behind it then just bolt on the master cylinder and the clutch pedal box. The hardest part is fitting the clevis pin for the clutch pedal, I found swearing loudly helped  . Is this a road legal truck? if so you will have a mountain of paper work to do for the body swap |

yes im waiting for the cert plates to turn up clevis pin?? looking up there scares me big time!!!  so will the accelerator and brake pedal need to be changed, the body i got was a auto with a blowen engine, so i just want body swap only, Body swap wont be a problem as its a standard item, all i have to change is the colour when getting a new rego. |

When you do the swap keep the plates off the firewall from the old car. These match the chassis no stamped near the rear wheel. Also a little know id thing to watch out for is that when they vin the car they also etch the vin into the rear window so you might have to swap the rear window as well

It's not that bad it's just fiddly, it took me a couple of beers to do it with my fat mitts You don't need to change the brake and accelerator pedal but it is worth cutting the brake pedal so it's smaller so you can get your foot on the clutch. |

Oh and one more thing, you have to bridge two wires in the auto transmission loom that goes to the neutral switch so you can start your engine. It's easy to find what wires you need to bridge by using a ohmmeter on the loom coming out of the auto while moving the selector, I'll go have a look and see what the colour codes are to make it easier.

Heres a picture of the clutch pedal box, it uses the same mounts as the ecu. The large loom is the autp loom to the ecu  The black cable on the right goes to the ignition barrel, it's what stops you from taking the key out if it's not in park. Heres the wiring loom that goes to the auto  The two wires you need to bridge are in the medium size plug, the colours are green/black and black/white, they are the ones that have been cut |
