I have recently acquired a 1996 Cushman 3 Wheeled Truckster(I think), it’s a Type G with 2 different Model #’s: 1. 3WATM FLATBED 2. 898475A. It is powered by the 327 Engine & has an Automatic in it. I would like to identify the Make & Model of the Transmission along with locating Parts Diagrams & Parts Suppliers. Any and all help is very much appreciated.
