I had to replace my transmission cooler/condenser a year or so ago. I don’t remember which one I used but more importantly, you’ll lose some transmission fluid and all of your refrigerant when you pull it. I noticed my transmission fluid was extremely burnt. I replaced my filter and needed six quarts of mopar fluid. Use mopar fluid. I used castrol the next time and my transmission acted strange. Just did it again using mopar fluid and all is good. An auxiliary transmission cooler is also a good idea as these things seem to run pretty hot, especially if you tow with it.
