Hello:) Just bought my first lexus today and am unsure on a few things. When I am between the 40 and 45 mph range and trying to drive that speed the car jerks. Its fine if I go right through that speed all the way to
50 or higher. Could this be a transmission issue or maybe the throttle body that needs cleaning? It seems like the car is confused whether or not to upshift. Thanks in advance for the help!! :)Nat- posted
