Most of the improvements have to do with shift control via the valve body. AOD INSTALLATION STEP-BY-STEP. STEP 1. Disconnect the battery, drop the exhaust and tailshaft — stick a bung up its bum to prevent oil spillage. Then disconnect shift linkage, kick-down cable, vacuum modulator hose, starter neutral switch, speedo cable, starter motor and the bellhousing's dust cover. The metal pipe is 3/16 so if you can fit a 3/16 id rubber tube over a 3/16 steel pipe that must be a tighter fit than a 1/4 tube. I'm ordering 3/16 to replace the carb advance pipe that looks tired so I'll just add a few inches to do the modulator when I next have the car on the ramp. The resulting loss of power will increase the demand on ignition. The Electronic Control Module will overcompensate, leading to engine surging.
