Here are some steps which you should follow in order to diagnose this P073A fault code:

• Initially check the integrity of ATF. With the help of dipstick check its level while running and when idle. The process varies a little between different manufacturers. However, this information can be easily found with the help of service manual or it will be printed in the dick. Ensure that the fluid is fresh and free from debris. If you don’t remember doing a transmission service, it is always good to check your records and service the transmission accordingly. You will be surprised how dirty ATF can affect the functionality of your transmission. Always check ATF level on flat surface to obtain accurate readings. Ensure that you use manufacturer recommended fluid.
• Do you find any leaks? If your fluid is low, then it's probably going somewhere. Check your driveway for any signs of oil tints or puddles. You may not know, but this may be your issue. Either way, it's a better idea to address them as well.
• Check for damages in the transmission control module. If there is damage in the component itself or elsewhere, where it may be subject to the elements, visually inspect them for signs of water intrusion. This can more likely cause an issue in many possible ways. If you find any signs of corrosion on the housing or the connectors, they are a good indication of the problem.
• If everything seems to be perfect as now, depending on the capability of the OBD 2 scanner, you have to monitor the gear position and check for its functionality. If would be easy to let you know, if your transmission is shifting or not by its drivability. Is it floored and keeps accelerating very low? Then it could have been stuck in the high gear (4, 5, 6 and 7). You accelerate it as fast as possible yet the vehicle's speed never goes as fast as you'd like? Then it’s probably stuck in a low gear (1,2,3).

Common Mistakes When Diagnosing the P073A Code

• The internal transmission is faulty.
• The transmission control module is defective.
