The adjustment goes as follows: Disconnect the carburetor rod (unsnap at ball & socket next to switch) and move the detent sw. lever to closed throttle position until the lever hits the stop. Reconnect the carb. rod while holding the detent sw. in this position. After the carb. rod is reconnected, push the accelerator pedal to wide open throttle (you can do the same from under the hood by moving the carb. rod to W.O.T.). Let the carb. rod and switch lever mechanism return to the resting position. This should align the internal switch contacts into the proper operating position. Start up the car and give it a try. You should feel the stator solenoid working at idle (variable vane mode). You may feel the car tending to try to creep ahead when in gear and at idle. This is normal. As you accelerate, the variable vane will shut off. When you go to wide-open-throttle ("floor" it), the detent switch will engage the detent solenoid, locking up the torque converter vanes and causing the "downshift". If the engine is running at too many R.P.M.'s, the downshift may not occur due to a safety built into the tranny.
I installed two 12V indicator lamps on my lower-left dash to allow me to monitor the status of the detent switch. One side of both lamps are grounded to the chassis and the other leads are connected to the switched lugs on the detent sw. Keep me posted & good luck!! Jim
