Help another new problem appeared. The power shift transmission won't shift past first and second gear, I replaced the speed sensor thinking that will fix it but no luck.

    May be problem in shifter or shift solenoids. Need to test voltage at solenoids and ohm them out.

    That is a good place to start. thank you. What should the ohm reading be on a good solenoid.

    I’m thinking somewhere around 30-50ohm’s but not real sure. But they all should be close to each other. As far as ohm reading.
