<font color='black' size='2' face='arial'>I DO NOT like the on-off toggle switch for the OD's as I would downshift out of OD and forget to toggle the switch to off so I went back into OD as soon as the third gear switch was reengaged. To combat this I used a standard electrical control scheme called "Three wire control" to engage the OD relay but drop it out when the shifter switch opened. To re-engage overdrive a pushbutton would activate the relay and latch itself in so the pushbutton was just momentary. Does that make sense? I can do a drawing if not clear. Steve

<div>For all of my 24 years of SCCA racing, I had the O/D switch mounted on my shift lever. Very convenient, and allowed for faster shifting.</div>
