Buick 1999 Park Avenue OBDII Code P0742 Rough Shifting

[arekusu881]

I have a 1999 Buick Park Avenue with 243,xxx miles on it. My transmission started shifting rough on occasion. It comes and goes pretty randomly. Sometimes it's really bad and I'll get a service engine soon light with a P0742 "torque converter clutch circuit stuck on" code. Sometimes it will start shifting hard and clunking and I'll shut the car off for a few minutes. When I turn it back on it disappears. I ended up getting a transmission fluid flush and the problem went away for maybe a few weeks. It's back now and seems to be getting worse. Sometimes the transmission doesn't engage at all when I give it gas.Given the description I've given here, does anyone know what I can do about this? Unfortunately I am broke and I can't put any more money into it. 100$ yes, but anywhere north of that no can do

Show me what your fluid looks like and confirm the level when fully warmed up and after a 10 minute drive, follow the owners manual for how to check the dipstick. But I want to see this fluid, put it on a paper towel

Also did they change the filter with the flush?

Also it may have 243K miles on it if its the original trans. It may be past life support.

They didn't, I didn't have the money unfortunately
