Is this a new tranny? Check the governor gears. After checking try this method. New transmissions sometimes get stuck in first. Accellerate slowly. When is should shift to second, turn off the engine for a few seconds. Coast for just a few seconds. Throw it in neutral and crank it up. Accelerate. It should shift into second. Try a few times. If it fails to shift, you have problems inside the tranny.
