Hi! I own a honda city steermatic model with cvt transmission. I gave my car to mechanic for suspension, steering and axle work. Somehow he had to extract some gear oil and without knowing replaced almost 1 litre of gear oil with ATF transmission oil instead of CVT oil. Car total mileage is around 140k and never had any transmission issue. What should i do now? Go for transmission oil change or complete flush? I have heard that complete flush should not be done for cars with unknown service history. Please guide.
