Anybody ever have issues with the hydro walk SD transmission? Got this unit from a customer who had just put a brand new engine on the unit(Why? idk). But, whatever the case, it’s a pretty clean unit that now has a new motor with a transmission that they don’t make parts for. It seems like it has plenty of power in reverse but like 1/2 in forward. Any input appreciated, if it wasn’t free and didn’t have a brand new motor I’d just scrap it.
