2 speed jetaway pitch/switch adjustment

[oldcutlass]

Thanks ahead of time- I'm new to the site and have a 1967 Cutlass 2dr Holiday Coupe with a 330/ST300 2 speed switch pitch transmission.

I've read pretty much all the way through most of the tech here, and in a few places you come close to explaining when, where, and how the switch for the passing gear/pitch angle on the accelerator linkage is set but don't quite get there. How is it set up???

Welcome! The switch that cotrols the variable vane should be located on the firewall (driver's side). It is connected to the carb. linkage and is actuated by the movement of the linkage forward and back. It is round, about 3 inches in diameter, and has three 1/4" male terminals. it . One is the 12V feed, one is for the stator solenoid and the third is for the detent solenoid. These solenoids are located in the tranny. The two wires that plug into the switch and go down to the tranny plug onto two 1/4" male terminals which are 90 degrees from each other. The connector is located on the driver's side and towards the rear of the tranny. Make sure you have continuity from end to end and all connections are clean and tight. If you do remove any wires from the kick down switch, make sure you mark which wire goes to which terminal. There is a calibration proceedure to align the contacts inside the switch. The stator solenoid is engaged at low acceleration and pitches the angle of the vanes in the torque converter. It disengages as you accelerate. Then, at wide open throttle (WOT), the stator rengages at the same time the detent (kick down) solenoid engages, locking up the vanes and causing the downshift. If you are runnig at too many RPM's, the downshift won't occur due to a built-in safety. You get about 20% more torque at the rear wheels when the kick down occurs due to the action of the vanes in the torque converter. Keep us posted if you need any further assistance on this issue. Jim
