SNIP so, i just bought that t86/r10 overdrive.. does anyone know what gear ratio is in the 62 classic 196 rear end? or did they come with several? SNIP Dunno, but I can look it up in the AM I think if you'd like SNIP i found a wiring diagram for the overdrive. all these switches and crap the guy had everywhere. is there a simple, more stock looking way they were wired up? SNIP I have a wiring diagram for your year, I would have to make a copy and get it into a format that I could send to you. As far as simple, the factory parts are to the best of my knowledge at this time (to be verified); The O.D. relay used to turn the unit on or off. 3 wires The Kick Down Switch, manually operated used to drop out of over drive for acceleration, 4 wires The O.D. Governor used to keep the overdrive from functioning under a given miles per hour, I think about 30 or so mph. 2 wires. The O.D. Solenoid, used to shift the over drive in and out as it functions as a 2 speed transmission. 2 wires And one wire going to the distributor used to short out the ignition so the engine will not run while the O.D. transmission is being shifted. This simulates (rather crudely but effectively) the action of taking your foot off of the gas pedal and depressing the clutch while shifting gears as you would for a standard transmission. John thanks for all the help everyone. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
