Hello, everyone. I am new to the forum so bare with me. I just got finished replacing my AC evaporator and heater core myself. I am an educator with little mechanical experience so that was quite an undertaking! I am happy that I have it all put back together and look forward to charging AC system soon. I still have yet to figure out how to repair my antenna which is in pieces in the passenger foot well. Any thoughts on that would be appreciated.

My bigger issue now is that my transmission is in limp mode. I had pulled off the throttlebody and replaced the TPS and idle air control when doing the HVAC box because I was having a problem with the transmission shifting from 2nd to 3rd when cold. Following these two new parts, my jeep is shifting great. The first time I drove it I failed to put a coolant hose clamp on properly and coolant went everywhere. A friend said that I could just hose off the engine bay to get all the sticky coolant off. When I got home I did that, and had gone for a drive afterwards and all was fine. The following day I started it and it seemed to have trouble Starting, it turned over fine but sputtered a bit. My check engine light came on and my tranny was in limp mode. I went to advanced auto parts today and when the transmission was cold it shifted normally. When it is hot it goes back into limp mode. The following codes came up: P0743, P0753, P0748, and 01765. I did some reading and checked my transmission fluid levels and the fluid is clean and level is perfect. It wasn’t 20,000 miles ago that I did a fluid and filter change on that. Do you guys think that the spring off with the hose could have something to do with these four codes? I am going to go out and unplug those as I remember unplugging them during my HVAC box fiasco. My thought is that maybe some water got in there and is causing some sort of short? Any help would really be appreciated. Have a great day!
