How much does it cost to fix the governor pressure sensor in a dodge durango?

I have a 1998 Dodge Durango. The check engine light is on. The diagnosis is P1762 and P1763 indicating the Governor pressure sensor offset voltage is too high or low. About how much does it cost to fix this? The truck only has 78,000 miles on it.|||It is a little costly because you have to replace the gov pressure sensor and transducer at the same time of repair, at that time a service to the transmission is required. All the work is inside the valvebody of the trans, Only quailified techs recomended. 350 to 450.|||a local transmission shop is going to charge you anywhere from 150-200 bucks to repair it,good luck
