My 1989 D-150 has a 3-speed automatic transmission and the 3.9L Engine. Here in the Houston area, this truck lacks gearing to keep up with traffic on the freeways and toll roads. I want to retrofit a 42RH transmission to give this truck overdrive so the engine can keep up with high speed demands. Any and all help to get sources for a transmission to anyone who's done this type of conversion would be helpful!
