I have replaced the output shaft speed sensor and governor solenoid and transducer and still no automatic shifting but will shift manually to third with relay removed

My suspicion is that your intermediate band has failed (or the strut or anchor has fallen off), and you don't actually have 2nd gear. This happens often with the 48RE, but the 47 is configured the same way, so it's always a possibility. Guys will feel a late shift out of first gear once you get enough road speed, but they're actually feeling a 1-3 shift because it tried to shift to 2nd earlier, but there was nothing there.


Idling at a stop, pull the shift lever from Neutral into Manual Low, and then take off normally. Once you're rolling at about 12-15 mph, bump the shift lever up into Manual 2nd. Does it shift to 2nd?
