    I was watching the show today and got quite a bit of good info that will come in handy with my 4l60e.
    Maybe somebody can help me with one thing he said...... Ian was comparing the 700r to the 4l60e and said the 4l60e used a stand alone computer and without it the transmission would not shift out of 2nd gear. Thats my problem....My tranny wont shift into 3rd. Is there a way to check the system to make sure the computer is communicating with the tranny? I really dont want to rebuild it if I don't have to.
