Your problem is: 4-5 gear driving at 40-50mph rpm moves +/-200 the LED's don't change. Your problem can be one of the following: 1. Vacuum tube from the throttle body. 2. Faulty torque convertor 3. Faulty valves box. Start with #1, then 2 then 3.
I don't think that there are faults there. When I got my car had some of the above + other. The problem was that the ECU forgot the settings due to the battery being removed. I guess that all you need to do is to program the ECU.
