Sometimes my automatic transmission behaves a bit strange. It will only happen when I accelerate on a slight uphill road. One out of two things can happen, ruff gearshift or the transmission takes far to long to decide to shift gear. Usually I help it a long and shift manually, but if I wait long enough it will eventually change. It doesn't happen often, once or twice a month. Should I worry about it? Massive failure in progress?
