So my 300SDL has some shifting issues, but not at all times. It happens randomly and usually when it happens is out of first gear. Also what I have noticed is that the brake light will flicker on and off when this happens. I tried checking the kickdown switch but could not see anything. I did not try to remove the plastic covers under the steering wheel, but will do so later tonight. I checked the e brake and it is not loose when the brake light it flickering. If there anything else that could be going on?
