Why is my 2006 Ssangyong Musso going into reverse when it's cold?
Asked by Graham
My 2006 Ssangyong Musso sports 4x4 diesel only goes into reverse gear first thing, when it’s cold, or when it wants to, could it be oil or electrical?

31 Dec 2021The one thing you haven’t told me, Graham, is whether your Musso has a manual or automatic gearbox. If it’s a manual, my suspicions would be with the clutch. If a clutch plate is damaged or worn, the clutch sometimes doesn’t fully disengage. That can lead to the gearbox not wanting to select gears from standstill with the engine running.
However, if the transmission is an automatic, then you could, indeed, be looking at a low transmission-fluid level. Unfortunately, the automatic gearbox in this vehicle doesn’t have a dipstick for easy checking of the level, so the first thing to do is take a look underneath the car to see if there are any leaks form the transmission. If there are signs of a fluid leak, then the vehicle needs to go to a transmission shop to have its level checked and the leak fixed.
Overall, the automatic transmission in the Musso Sport was a solid unit, but it’s now getting on a bit in years, so who knows what state the inside of the transmission is in. If you’re lucky, it will just need a service and a new filter and fluid. But there could be a lot more going on inside. Automatic transmissions rely on simple principles but very complicated assemblies. The valve body is a great example: While it relies on relative hydraulic pressure to choose a gear, the reality is a hugely complex circuit of hydraulic passages and valves.
