Try a ecu reset. Disconect the battery for aprox 15min, then reattach it and see how the car goes. When was the trans fluid changed?? Does not sound good though. You could also try emptying the trans sump (5l approx) to check if there are any metal bits broken off from inside the box

I would check the colour of the fluid as well by pulling up the ATF dipstick. If there isn't any oil then you should fill it to the correct level using Mitsi SP3.

If it doesn't get any better after that (and an ecu reset) then I'd be doing what David said, dropping the sump and PRAYING my arse off that there is no metal chunks in there.

Hi guys.Fluid looks ok.level is ok.Does not smell burnt

 

[bradc]

Reset the ecu, then dump the sump contents into a clean bucket just so you can pour it back in afterwards if you want to.

 

[Guest]

any idea what would could cause this. Would it be advisable to have codes scanned first before disc battery

Do the battery, it won't hurt anything. Also check your AT fuses.

Limp mode can be caused by a few different things. It doesn't sound like overheating. There are a couple of sensors that may have failed as well -

Throttle position sensor
Output shaft
Input shaft

Start with the battery and fuses though, as I would assume that where your problem lies.

Good luck

Would you know fuse numbers and location Thanks

 

[pu-11-me]

Did you just want me to drive over and fix it too?

I'll take a look man and post back shortly....

 

[pu-11-me]

It should be the trans one next to your right knee when your driving.... I couldn't find a picture, sorry

 

[Guest]

Thanks I maybe a bit slow,but my hand book shows fuses and doesn't show a A/T fuse or lacation

 

[dimi_108]

Have you emptied the sump yet to check for metal chunks or are you ignoring Brad's suggestion?
It's definitely something you need to do.

Hi Dimi I will get some fresh oil and change to morrow and investigate the fuses
If at worst the box has to come out Can you recommend a trans guy who has the knowledge on these boxes

 

[Dr_Josh001]

Make sure it's Mitsubishi ATF SPIII or Amsoil SPIII, anything else will cause more problems. If you've had the car a short while do you know if it was freshly imported? The fluid may have been drained and refilled at compliance with incorrect fluid.

I think Castle hill motor sport rebuild dimis

Also try contacting MEEK. They can service our auto boxes now, plus they have a contact who is a master at automatic gearboxes. I forget his name, but owns a rare Monte Carlo HH VR4 automatic.
