Nissan Juke 2012 118060 km
I have had gear changed after the gear chain got cut. Since then the car can't climb any hilly ground. But can move on a flat or sloppy ground for a while.
Gear oil is changed, Spark plugs changed, coils changed, If it cools for sometime it can climb up to a certain limit then just stops and can't accelerate or show any check engine.
