I had that setup behind an inline 6 250 motor in my old '67. I got 21 MPG on the highway. I'm not sure how the electric shift solenoid was hooked up from the factory, but mine was wired to a switch on the dash. I'd push the T handle in to make the overdrive unit freewheel like a bicycle. Then I'd throw the switch, lift my foot off the accelerator, and as the RPM of the motor slowed down, the overdrive unit would kick in. It was kind of tedious to engage the overdrive unit this way. I'm assuming that the factory setup must have been a little less idiot-proof.
