That sucks man! I blew the tranny on my 7.3L 1 week after I bought it... shit happens. If you plan on towing with it a lot I would recommend doing every trans upgrade you can but it will cost around $3k. The other big thing is that Ford put a tiny cooler on it and these transmissions are very suceptable to heat. A larger cooler wouldn't be a bad idea. I solved my problem by selling that truck and buying an OBS CCLB with the 5 speed manual lol good luck!
