So I got my jeep one year ago and she’s ran great till now. I was having issues with it running a little hot so I flushed the radiator and washed it off and it’s running better and have a new radiator on order. Since she’s a RHD, everything has to be ordered, lol. I am getting a LOT of heat from floor and she has thrown transmission codes. Transmission is running fine but could it be getting hot? And what can I do to help cool it?

I have a 6 cylinder 4.0 super tech.....don't know on trans
Super tech is the house brand oil and filters you find at Walmart. The Jeep 4.0L engine is a PowerTech, though rarely does anybody call it that -- almost universally it's just known as the 4.0L engine. Since your Jeep is kicking out automatic transmission fault codes, it's likely safe to assume you have the auto, which for a 2005 model would be the 42RLE transmission.
