Today I was pulling out of my driveway slightly uphill and suddenly felt the engine revving with momentum in the car slowing down I then realised the gears weren't catching or sliding was making these sounds too.. not loudly whizzing sound while in gear, pulled over had a pickup truck to a garage. During this time as we where lining up car to pick her up it was put in gear drove normally again only to lose momentan make same sounds as if the gearbox has just catching fresh air.
Was told by mechanic from what he seen that it could be the clutch or the gearbox. I asked what would make it drive again then suddenly revert back told could've been the teeth on gear box are broke where thrn not catching in gear, so he will not know until they open it up and see what's going on, I hope the small job, I'm not getting my hopes up ,probably the gearbox
2016 cx-3 diesel 130km. From what I said any idea if it's either clutch or even both
