I have an old HR215 SXA that runs perfectly, except. I recently moved and folded the handle while moving. Prior to that everything worked like new. After the move I went to use it and the transmission won't engage. I took it to a small town small engine repair and he said there was something broke inside the transmission. Looking at about $500. to repair it so I brought it home. Getting curious I turned it up on it's side and moved the gear selector handle. The little lever on the transmission doesn't move at all when the lever is moved. Does that indicate a broken cable? Both ends are still connected. Also do you have to take the transmission out to replace the cable? Thanks for any help. Howard
