Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
The first thing you need to do is scan the engine and trans computers, ECM and TCM for codes set.
Can you get this done at a workshop during your trip to Brisbane?
Does the vehicle have an auxiliary transmission cooler?
What size caravan are you towing, plus passengers and luggage etc?
Ok, hopefully not a big issue.
There will a code set in the ECM, so can we get that checked please?
Do you need any further help?
I hope my advice has been of assistance to you.
