Purchased 2002 Toyota 4runner SR5 with 123000 on it. Love everything about it, except after about 1,000 miles there might be a transmission shudder. I noticed the tranny might be "hunting" between 30-40 mph and around 60 mph depending on load. I am a former VW owner with "drive by wire" gas pedal, so I am hoping this is nothing. Anybody with similar symptoms or experiences?
