Hello, there is manufacture flow chart for this code, in which they have you replace the a/t clutch pressure control solenoid A, B, and C, then clear the memory, and test drive. If code comes back, they, have you replaced shift solenoids a, b, and c, clear the memory and test drive, if code returns, they want the transmission pulled and rebuilt the hydraulic system. So, in the long run, putting in another used transmission is obviously going to be a lot easier. These are decent vehicles if the engine is maintained. Oil changes and routine maintenance and they can go to 300k. With line pressures jumping all over the place it can be the pump or the control solenoids, but it's not worth the time or cost trying to replace all those parts. If you can find a decent used transmission, it can be worth it. It's a matter of what you want to spend. The used vehicle market right now is very high, so it depends if you think the rest of the vehicle is worth putting a used tranny in. One of the first things I noticed with these vehicles at that mileage was upper camshaft bearing noises. It sounds exactly like a squealing belt. If you don't hear any upper end noises, then it might be okay. Also, adjusting the valves in these is extremely easy and should be done every 30,000 to 60,000 miles. But by the sounds of that transmission, it will need to be replaced,
I would also have the entire system scanned for codes, not just the PCM, to see if there's anything else that would need to be addresses, i.e. airbag codes, ABS codes, etc. Hope this helps somewhat.
