Tranny questions
Have a 66 F100 with 300-I6 that is going to be running 190+ horsepower. Will the 3 speed overdrive hold up?? Also have a AOD automatic trans from a 86 pick-up. Anyone converted to this? What has to change?? Thanks Bob

The T-85 OD is the model that was originally designed for the Lincoln engines and is very strong. It has a "crash" low, and to use it you need a kickdown switch, an overdrive relay, and wiring to the governor and the solenoid on the transmission, and a lead to the ignition coil. (shorts the coil during kickdown). Since Ford used it with 6 bolt engines, you can use the passenger model or the truck model. However, to use it with a 53-60 truck, you would have to use a third party bellhousing that has the truck motor mounts on it, or you would have to use a passenger or later truck bellhousing with the passenger main drive gear and use a tailshaft transmission mount and side engine mounts. You would have to use this with the AOD as well, and for all I know you may be using this now to accomodate your 300 Six.
