Hi I'm having a problem with my Nissan micra k12 automatic gearbox 03 plate.
Every now and then the gears fail to change from 1 to 2. Nothing works unless you park switch off the car and turn back on and then it works fine. It's now starting to over rev at 40mph where it doesnt change from 3 to 4. I would really appreciate a diagnosis to this and see if it's worth keeping the car. Most people I've spoken to have told me to drive it till it packs up but I would rather salvage it as it works perfectly otherwise
Could be internal wear and tear on components or an external fault . Needs scanning for fault codes but better to take to a local , accredited , reputable Auto Transmission specialist for checking and assessment
