I have my overdrive hooked up to relay, governor, and solenoid, but a toggle instead of the kickdown switch. I usually leave the toggle on all the time and just let the overdrive kick in after 30 mph by lifting off the gas to lower the rpms. I think I heard Jay Leno say to just flip the toggle on over 28-30 for a better response. Can anyone verify this. I don't want to mess up my coveted overdrive. Thanks
Based on my speedometer, the overdrive is enabled at 30mph, and disabled at 25mph.
I am a supporter of letting the automatic overdrive work automatically as designed. There is sufficient protection in the governor/solenoid/relay system to ensure proper operation, and the kickdown feels just like an automatic transmission.
