Hi everyone
I had also same Problem can you determine which sensor I need to swap on?
Big help
Thanks.

For your reference, the diagnostic manual is over 2000 pages long. Too large to send digitally. If you need a manual you will need to contact a local dealer.

I had this code on my truck also. After doing a lot of digging around, mine turned out to be a wiring issue to the sensor. The insulation on the output wire from the sensor, had cracked and split, where the wires entered the wiring harness. Moisture was causing a very minimal short to ground. It seems to me these sensors are very sensitive to ground shorts. Took all the plastic covering off the harness and used brake cleaner to clean everything up. Taped it all back up and the truck has been running ever since!

It was the sensor. I spent 2 days on it and they finally told me they had the code about 2 weeks earier and found no transmission fluid in it, so they filled it. Once I cleaned the sensor out it worked fine. spent about a week hunting down a manual just for a clogged sensor.

DTC 524225-4 - Transmission Forward 1 Pressure OORL

The sensor is probably bad. Swap the fwd and reverse pressure sensors. If the code changes to a 524223-3 (reverse sensor) the sensor is bad. If it stays with the same code, there's a problem in the harness or with the computer.
