Getting a couple codes on the transmission
 

On my quadra trac tranny I'm getting the P0731 and P0734 codes. I know in need to replace the input shaft sensor, but will that give me those codes as well. Just picked up the jeep a couple weeks ago. I knew I would need to put some work in and that's fine by me. I would just like to get some other more experienced jeep owners advice as well. The tranny fluid looks and smells like new. The whole system has 231,000 on it. Any advice would be appreciated.
