Jackaroo problem - looking for advice.

[ash77]

Hi, I have a 94 Jackaroo 3.2 petrol auto which has a weird and very intermittent 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.

alternator issues,

either dodgy connections or it's on its way out

these are very temperamental about voltage, if you replace the alternator, make sure it has a long warranty, or is genuine... they have a habit of killing low quality alternators

Hey.
I have just bought a Jackaroo, and had the same issue. Sometimes while driving the check trans light would start flashing and the car would drive like a POS.
After some research it is a safety feature of the transmission. When the computer thinks there is a problem it goes into limp mode and if in "d" it stays in 3rd (from memory). L and 2 still work as normal. THe only way I could drive normally was to turn the car off, them start it again and it would be ok for a while.

I found that after a gearbox oil change I have not had the problem since. Someone else I read about removed a switch? from the side of the gear box, cleaned the contacts and hasn't had the problem either.

Hopefully this helps you too. Let me know if you need anymore info.
