Light Toggle between 4th & D
 

Those of you with the toggle of lights for the transmission between 4th and D,try cleaning and Tape around the connector to the coil. I don't know if they sell new connector covers so I used Hi voltage electrical tape around the coil connector make sure it is tight, and the problem went away. Suspected it was in that area as I changed the plug boots previously and toggle went away for a bit then came back.Voltage must be leaking to ground causing that toggle,go figure. (The coil covers are old and loose fitting)
