So i got a 2003 Cadillac seville sts first off the transmission cooler lines just got replaced by myself because they cracked and fluid was all over my driveway I fixed it dropped the pan changed fluid since it has never been done to the car it worked perfect but 2 weeks later the car didnt wanna reverse or move in nuteral wouldnt roll back at all got in today and it was back to normal drove and drove but the longer I drove the more the trasnmsission slipped and would berly get power at a green light to go it starts off slow but soon as it gets going its normal again no codes are coming up no service engine lights are coming up nothing the only thing thats been popping up lately is low oil pressure shut off engine and when I floor it and look in my rear view i see a cloud of oil mist i think the oil switch leaking my car only gots 97k on her by the way never had problems with her she did sit at tow yard for a year and 2 months I just got her back 2 months ago also sometimes just revs

Hello, sounds like a transmission issue internally for sure. I can't say if it was or was not caused by the cooler line repairs. It's impossible to know. Also, it's impossible to know if it's due to the fluid change - perhaps even the incorrect fluid is in the vehicle? Did you use genuine General Motors fluid as specified for this vehicle?
As far as low oil pressure and blue smoke - sounds like internal engine concerns, not a switch concern.
