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.
Unless I missed something you do not specify if you actually get lockup or not. You said it shifts funny.
Drive it in third gear - OD off and see if it drops engine speed of approx 200 Rpm up a slight grade after it gets in to 3rd.
If it’s does then try it in 4th. If it’s does then you have lockup.
If it does in 3rd but you get no OD then that’s different animal.
Need way more info.
