I currently have a 44re in my 1998 d with a 5.2 I do a good bit of towing and my trans just went out so while I’m replacing it I would like to go ahead and purchase a more stout trans with a good warranty. Any suggestions?

Hi All, I have found a ton of info on these forums, and I did my own heater core replacement (among other things) with the help from these forums. I am now running into a problem that started "around the time" that I jump-started another vehicle, but I can't say that they are related for sure...
