Hi - I've been to archives and pajero forum, but thought I'd try a post here before joining paj forum. I have a coupla of questions:

. 5-speed box in 88-91 pajero was supposed to be a bit weak, particularly in fifth - are post-91 5-speeds considered durable? Would prefer engine braking of manual, but would go to auto is it's considered to be more durable.

. do the 3L V6s and 3.5L SOHC V6s have similar fuel economy?

Thanks

The 3.0 L V6 and the quad cam 3.5 have similar fuel consumption. In 1996 a mate and I drove from Mt Dare to Birdsville and both used 89L.
I don't know about the SOHC motor as it came later.

Mate, the only problem with the manual box in these models was 5th gear was a little weak. However if you follow the owners manual's advice and don't use it under 85kph they're not a problem.

The 3.5l SOHC uses more fuel than the 3.0L, in my experience, about 2Lt/100 difference from an NH (92 model) to the NM (2001)

Personal opinion, in an early model I'd take the manual (that's what I used to have), in the later model the auto is unbeatable.

Cheers......

I presume the NM is quite a bit heavier than the NH which could also explain economy diff...

A little. The twin cam 3.5 was in the NL which was not much difference in weight to the NM. The single cam engine came in the NM, slightly less powerful, runs (supposedely) better on lower octane fuel (the twin cam liked high octane) but likes to drink more of it, and is cheaper to produce.

The 3.0 Lt is not a bad engine when it comes to fuel economy, but it does lack a bit of low end grunt. Likes to be kept in the power band (above 3grand) to work properly, particularly in sand.

Might pay to check further but I'm almost 99% positive that they said the 5 speed box in my 1990 NG PJ was from the Canter's ?

Anyway , I have had no troubles with mine.

Apparently the trick is to run a special Caltex oil in them VXM from memory (M for Mitsubishi) , the standard stuff is VX.

I thought the Canter box was used in the turbo-diesels only, but if also used in the V6 I'd be happy with that as it should be reasonably durable coming out of a truck...

AFAIK , both the V6 and Diesels used the same gearbox , from the Canter. Thats what I was told when I had some work done on mine (not the gearbox).

It was the 2.6's that had the sigma box.

Whether its 100% correct , you now have me wondering . . . I have a manual at home , I'll check.

Happy to have some prove otherwise.

The 85 NB I had had the 5th gear bearing problem.
This was the 2.6l 4 cyl model. Not sure if the later 3.0l V6 had the problem, as it was a different gear box in the MK I shape.

The problem is the needle roller bearing with too few rollers,I think the fix they did about 87 or 88 increased the rollers from about 35 to 42.

The MKII body, 90 to 99. The 3.5l V6 and the 2.8l td had a bigger gearbox than any previously. And the diff and axle were bigger too.
Mitsu lifted the body 20mm off the chassis compared to the 3.0l V6 to fit the gear box under the body. It is still tight under there and it is common to see a little reforming of the tunnel if they have come out and gone back in again.

Not sure about the NM/NP MK III shape gearboxes.

I don't know if you are looking to buy one, but I am selling an 88 5-speed turbo diesel. I think it is the second last ad in the trader section.

It is a great little car, bought specifically for its great condition. We are only selling it due to a company landcruiser being driven now.

Let me know, as the price has dropped a bit (I can't seem to change the ad now).
