Hi guys I've got a Ford 655d that is new to me. I've been doing a lot of work such as rebuilding the engine Etc but I'm having an issue when you put it in forward or reverse it jerks and starts pulling at low idle. I tested the controller and the voltage slowly goes up to 7 volts but because I haven't put brakes on it yet it makes it very difficult to operate. Does anyone know what would cause this issue? It will literally slowly climb a hill at idle to a point. Thanks for any and all input
