Mitsubishi Triton Gearbox & Transmission Problems

Why does the speedo in my 2004 Mitsubishi Triton bounce up and down and make a weird noise?

Answered by CarsGuide 8 Feb 2021

The cable that drives the speedometer is a likely candidate for this in some cars, Aaron, but mainly older ones than your Triton. The cable will eventually run out of lubricant, at which point it can bind up and won’t turn smoothly (the cause of the hyperactive needle) while also making a dry squawking noise (the budgies). But, from memory, your car has an electronically-driven speedo, so the cause is more likely that the speedometer itself is worn out and causing internal friction (for the same set of symptoms).

Mitsubishi Triton 2000: Problems putting it in reverse

Answered by CarsGuide 16 May 2020

There are three (generally speaking) things that can be causing this problem, Mark. You could have a problem with the clutch, the gear selectors or something internal in the gearbox itself. A worn or collapsed bearing or mangled gear cluster could cause this, but I’d expect other symptoms like horrendous noises and the refusal to select some gears at all, not just randomly. If you’re lucky, the cause could a simple mal-adjustment of the selector mechanism.

Meanwhile, you’ve told me you don’t think there’s anything wrong with the clutch but, to be honest, I’ve seen these same symptoms before on cars with worn out clutches. Sometimes the actuating fingers of the clutch break, other times there’s just too much wear for the clutch to function properly. Sometimes it’s as simple as a leak from the clutch’s hydraulic system or a stretched clutch cable. But either way, clutch problems can certainly cause this sort of grief.

Reverse can be hard to select because the clutch is not disengaging fully, so try this experiment: Turn the engine off and try to engage reverse. If it goes in easily every time and only baulks when the engine is running, that’s a classic case of a dying clutch.

It could be a number of things, and the only way to establish the cause of the light flashing is to have a mechanic check it.

Answered by CarsGuide 19 May 2017

It could be a worn synchro, but I would suspect it’s more likely to be a worn clutch. Have a mechanic check it for you.

Mitsubishi Triton 2016: Transmission shuddering

Answered by CarsGuide 4 Nov 2016

Without knowing more about the vibration you report it's hard to diagnose a cause, but we note that other Triton owners complain about a vibration on takeoff, which I suspect could be what you experienced. If it is I understand the problem has been referred to Mitsubishi in Japan for a fix, and that it could be a result of the changes made to the rear suspension on that model. We can't say it will get worse with age or when towing, but if you are concerned about it then you perhaps you shouldn't buy the car.

Mitsubishi Triton 2011: Clutch wear

Answered by CarsGuide 15 Feb 2016

Sorry. Clutches, like brakes and tyres, are always regarded as wear-and-tear items. It's the same for new cars. Without doubting your driving, many people are very hard on their cars.

Mitsubishi Triton clunking noise

Answered by CarsGuide 17 Jan 2014

It does sound like it could be a problem with the differential. At this stage you should continue to seek a solution with the dealer and Mitsubishi. We will contact Mitsubishi on your behalf and see if we can enlist higher up help.

Mitsubishi Triton: Will it overheat when towing like the Toyota Hilux and Prado?

Answered by CarsGuide 28 Sep 2010

There is nothing to suggest there is a problem with the Triton, but it’s worth checking the owner’s manual to familiarize yourself with any recommendations Mitsubishi makes about towing with the Triton. That way you will minimize the risks of having a problem.
