I have a Cat p6000 lift. Just resently recieved. Drove when unloaded now it has no forward or reverse and get a code e-43 on dash. It did have a seat switch, removed and 3wires were wired nuted together. Came that way. Running on LP. Forks go up and down. Does run little rough. Also can any one tell me what fluids are used for hydrolic and tranny. Both are low and not sure of grade or weight fo fluid to use.
