Dear All
I am new to this forum and I went through a complete rebuild on my Isuzu Mu
Wizzard, imported from Japan. The 3.1 Turbo diesel (4jg2) blew up.
Head cracked. The decision was to replace it with 4JB2? 2.8 Turbo
diesel. The saga came to completion last weekend. So I thought.
But we do not have expert Isuzu technicians in Botswana, Africa.
The Auto original gearbox do not shift gears at the right refs.
Need to get to 4000+ rpm before it shifts. I am not certain if it
goes into overdrive at all. I will destroy the new engine fast that
way. (less than 500 km on it.) The local guy here can not find the
fault. Apparently the communication is electronic and not
mechanical. The electronic sensor on top of the original diesel
pump was build over to the diesel pump of the 2.8. The question is
where are all the sensors connections, vacuum hose bits etc that it
will need to work, shift correctly. Any suggestions of a good
workshop manual I can import? Help urgently needed.
Changes made:
Different diesel pump
New engine (2.8) sub assembly
Different manifold
Different turbo
The vacuum harness is in a mess.
Electronic harness seems to be O.K.

Thanks
