No I am not kidding, you are stuck in the old days where autos can not handle down shifing or up shifting. The toyo auto can do it well. I up shift or down shift at will with no ill effects. Autos can last longer if maintained, Just as you maintain the standard. The bearing on the side or counter shafts will wear even with synthetic. The manual has less contact area between teath and have more load on the bearing in a single spot. If the H151 is anything like it cusion the 4 speed, it has it problems like any manual tranny and will need some bearing in as little as 250kmiles. I have seen enough 40, 60 needing rebuilds before there time, as well as I have seen Autos needing rebuild before there time because of poor maintance.
The only two things you loose are about 10% less power, and 20% fuel consumption. no loss of control. The auto even may save you money over a clutch if it does not need the expence of a clutch job every 75k.
On road you are correct, the LC does not need a auto, but it is not hindered by one either. There is no loss of control on the road.

HZJ60 Why don't you just disconnect the front prop for a day ad run around with the CDL engaged to see what it would be like though I would not do this for too long because if the increased stresses to the diff and locking mechanisms. See how it goes but I think you are dead set on this conversion so just do it. I would advise taking more than one opinion on fuel consumption improvements though, and you should ask to see there fuel returns and calculations over a period of time because believe me I have brought up consumption figures up on other forums and in the pub and a lot of people will give you a lot of BS that is just out of there head which can not be substantiated

There is NO need for an auto on road in a land cruiser. No need at all.

You obviously haven't driven around the greater Los Angeles area!!!!

Seriously though, in heavy traffic - which is getting all too common on most of southern CA roads at least - I would make a strong argument that the auto is much better, more efficient, and will last longer than a standard. This point is made since you are referring to on road driving as your primary reason. I've driven literally thousands of miles in both std and auto trans trucks in these conditions and the accelerated wear on std trans due to constantly shifting, playing with the clutch, etc. gives you problems. You can smell your clutch giving up its life!

I could go on about why you'd want AWD all the time too but you seem to be set on having it be RWD w/ selectable hubs. I've got the hubs up front but for the purpose of trail breakages. But after trying what Robbie and others had done, it's just not worth it. The truck is what it is and I think I'm a little more safe with the handling AWD provides on and off road.

I guess the point is that there are many "real world" situations that make one or the other "better" but neither one is going to be just a black or white winner. I held out for nearly 10 years before getting an 80 for just this reason and tortured myself and family in a 4Runner and 60 (no offense!) before caving in. All I can say is that unless I move to Australia or Africa I won't be driving a stick again.

Good luck with your project though. Also, what about the new 6-speed that is in the new Tacomas? Is that an option for std tranny mating to any of the diesels?
