Dear Mr Kilmer, I'd really appreciate your help and advice on a persistent issue that I have with my car. It's an automatic 2016 Suzuki Hustler (82000 km mileage). The issue started with the gearbox light coming on and I've taken it to a local garage that recommended me to have it changed. So I've replaced the gearbox (a reconditioned) and drove for about 20k kilometres. The garage said that they'd cleaned the valve body and later changed that too with another valve body hence to eliminate any issues with the previous valve body. The light came back on after about 30 kilometres but there's no issue as such while driving. My problem is the warning light that keeps coming back up and don't really understand what the problem is. They also said something about the gearbox control unit being faulty but didn't replace that as it seemed fine after the valve body. I am from Sri Lanka but I'd really appreciate your help on this
