I could be wrong here, and I'd welcome any corrections from the experts, but I believe the reasoning for us not getting that option had to do with the import taxes in this country. This so-called "chicken tax" meant it was only economically viable to bring the 80 series here in its top-spec form: the equivalent of the VX Sahara trim overseas. To my knowledge, the Sahara models were only offered with automatics since they were meant to be luxurious and easy to drive for well-heeled buyers.
Anyway, I had mixed feelings about the A343 in my truck. On the one hand, they're very sturdy; you hardly hear a peep about them having issues here on the forum or elsewhere. In some situations, like steep technical climbs, they're also more user-friendly and forgiving than a manual on a heavy vehicle like the FZJ80. On the other hand, it is still a very antiquated design by modern standards, and makes the Cruiser more sluggish and inefficient compared to an equipped 80 series. I also found it left a lot to be desired on the trail: its shift patterns felt awkward in 4lo, almost like it was slipping. Engine compression was also subpar for steep descents.
However, I have also heard reduction gears are good to have in a manual 80 series, since the stock crawl ratios are not that great from the factory.
