I continued using my relay ,I cleaned it up working great, I eliminated the governor,kickdown switch and the coil wire. cleaned up my solenoid so it was working as it should. Put a toggle switch between the relay and the solenoid . When you are ready just through the switch while accelerating and let off quick and back on you are in OD Reverse action to go back into standard. No problems unless you forget to take it out of OD when you stop. Cant back up ND IT MAY ROLL ON YOU. Have to always remember how it works so you wont make that mistake. I love my OD It will cruise at 75 with no high rpms. My rear end is a 373 so it will do around 2300 rpms at 75 Happy driving.
