Trouble Code P0720 trannsmission gearing down?
When driving my truck it keeps randomly down shifting and staying stuck there for 1-5 minutes before it returns to normal operation. The transmission light flashes when this happens. It doesn't happen every time I drive maybe once or twice a day the past two days. I pulled the code and all data said "Insufficient reading of Output Shaft Speed Sensor and Turbine Shaft Speed Sensor". My question is should I assume it's a bad sensor or something else. Anybody else dealt with this? Thanks
