So today, after tackling a unknown battery issue, I finally arranged a battery from someone else (as mine has been submitted for warranty claim) started the car. Warmed it up, checked the functionality of the oil pump, checked for leakages, cleared all the errors and took it out. It worked well till I moved it out of the workshop, took it up an incline and brought it back down. Then took it out to the main road, as I gave it throttle, the vehicle jumped to neutral. I moved the lever around, backwards and forwards, the display showed change of gear but nothing as such was physically felt. Turned off the car, started it again, and it got into gear for a few seconds, moved forward and jumped back to neutral. Numerous such tries helped me get it back to the workshop, it gave the error code of the gearbox connector not connected, whereas it was, we decided to replace that, in the process, some gearoil was to come out.. The bit that came out, was burnt. So after having a discussion over potential solutions, we decided to replace it with a kabali replacement as it is in warranty.
