Two things you need to check; first you need to check your brake pressure there are parker fitting just under the frame on left side of engine close below the alternator. You also need to check your speed sensors for the trans mission. It really kind of sounds like the brake pressure is low not allowing trans to shift into higher gears. Another thing to check is the accumulator pressure, you have two one for brakes and another for the main hydraulics, they are located inside the frame in front of transmission on right side. You need to have someone that knows what they are doing to check and charge or rebuild the accumulators. They are charged with nitrogen and the pressure is 950 psi if I remember correctly.
