The solenoids were not replaced, the valve body was not disassembled.

I was thinking the reman converter was just a piece of chit. and it was the reason for the non lock up.Which is why I was asking about fluid fixes.

It has approx.30,000 miles since rebuild.

now I am thinking I should pull the solenoids and check the screens. And possibly replace?

I also had a caravan that set this code and put a new solenoid pack on it and it didn't fix that one so I have lost faith in the failing solenoid stuff. I considered that one a converter issue also, being a stock one with 200.000 on it we drone it another 75,000 with the light on.
