You mean the little OD box after the 727 as used on vans? They was hooked by a regular switch on dash. /Sten

If it has two wires it's OD. If it has three wire it's OD with a lockup converter. It uses a key hot + and switches through the - wires to get lockup and overddrive. There is a pressure switch you can get from the dealer for under $20 that will make OD automatic. You DO NOT want to come to a stop and forget to take it out of OD! Bad things!

The LoadFlight is a 3 speeds cast iron.It was available in some trucks for a period. The Loadflite was a pushbutton box without a park position.  The only common piece between auto 727 and loadflite is the case. The planetaries and clutches are of much heavier duty. The output shaft rides on a bearing instead of a bushing. These things are very tough. I will remember I read that they mostly been used in heavy motorhomes. The cast iron TorqueFlite was later replaced by the aluminum Torqueflite. Maybe somone have some add ons. /Sten
