Jackaroo problem - looking for advice.

Hi, I have a 94 Jackaroo 3.2 petrol auto which has an unusual and very intermittent (and hard to find) problem.
Very occasionally the 'Check Trans' light will flash, at the same time the voltmeter shoots right up to 16 and the idle drops or acceleration is affected. Sometimes the car cuts out completely and will not idle again once started. This may last from 5 seconds and then stop, or up to a minute before the car cuts out.
It doesn't seem to happen under particular conditions - just randomly, and can go days or weeks without doing it.
My thoughts are an electrical problem rather than transmission, and hopefully something real simple. I've had 2 mechanics check it out but of course the symptoms haven't happened while they've had the car!
If anyone has encountered this or has any ideas can you please share them.

Have either of these mechanics had access to a diagnostics scanner? If not then it might be time to find someone who does and have them scan the system for logged fault codes. Ultimately it could be the ECU itself.

Could be a dry or cracked solder joint in the ECU causing the intermittent fault, as RAY185 said use a scan tool to retrieve error codes should point you in the right direction.

The inhibitor switches on the Jack auto's apparently fail quite often as well.

exactly what he mentions happened to mine sometimes youd see it start to flash so you pull over shut it off restart & it'd be fine sometimes you'd be on the highway doin 100 ks & it'd just shutdown

I agree with your thought - I would not be looking too closely at the trans first up. I would guess that it is reporting the "check trans" fault just because of a voltage issue - bad connection, dying battery, bad alternator etc.
A lot of modern cars seem to report random faults in various major components when the real problem is just low voltage somewhere.

Thanks heaps for the replies - really helpful - I was pretty stuck for ideas before. Gives me a place to start.

you'll be better off asking it here - it's an american site for the isuzu trooper (if you feel like just searching, it's the 4L30-E transmission)
http://forum.planetisuzoo.com/index.php
there are over 3,000 owners there, all own petrols, most have automatics
ask it up, give it a few days and you will get an entire step by step procedure on how to fix it....
