I have a 1966 Pont StarCheif Executive w/ a th-400 out of a 66 Olds.... the stock one was bad, and now sitting in my trunk. Well the Olds th-400 is in and work, but i have one problem... it won't kick down. I have replaced the modulator valve.. and checked the vaccume, all good there. The only other thing i can think of is there is a switch in the trans that my be bad... but i see no wires other then my reverse plug. any help would be great, thanks
