Renault Koleos Gearbox & Transmission Problems

The best place to start for some professional advice is a transmission specialist. They’ll probably inspect the transmission in your car and will be able to work out whether it can be fixed or if it needs to be replaced.

If you do need a replacement CVT, there are three main ways to go. You could buy a brand new replacement CVT which is likely to be the most expensive course of action. The second alternative is to have the transmission shop recondition the one you already have. This will also be quite expensive.

The third option is to find a good, tested second-hand CVT from a wrecked Koleos and have that fitted. This will be by far the cheapest way to go. But the gamble with option three is that the same problems might happen again, and you’d be back to square one.

I agree that a 2016 model-year car is too new to be thrown away, but failures of CVT transmissions are more common than they should be. It’s something car makers need to look at when they consider future designs and engineering.

It sounds about right to me. Replacing a clutch in a car today is not a cheap exercise.

You don’t say what the transmission is, but I will guess that it’s a CVT, which was one of the automatic transmissions offered by Renault in 2011. I haven’t heard of such a problem with the transmission of the Koleos before, and it could be that it needs servicing and the oil replacing. Take it to a Renault dealer and have it checked.

You don't say which transmission it has; it sounds to me that it could it be a CVT? If so it might be the normal operation of the CVT you're experiencing. I would go back to your dealership and ask them to demonstrate how the transmission works.
