Well, the old Torqshift kicked the bucket a little while ago. In two days it went from shifting fine to limp mode, slipping, and some nasty looking fluid. Got P2703, P2701, P0766, P0757, P1744, P0741, and most likely unrelated p2199. Seeing as I don't have the cash to get a built transmission or have a reputable rebuilder anywhere nearby, I have scored a donor from an 06 F550 with the torque converter for a whopping $375 @ 140k miles. I am acutely aware of how necessary it is to do a thorough flush of all the lines and the cooler, but my question is what other little pieces of advice can anyone here offer that has caused them a headache or wished they had done differently? Gonna be taking this beast on next weekend, and would like it to go as smoothly as possible.
Also, as a side question, has anyone heard of a transmission dying this quickly and what might cause it? My truck has a pretty stout tune on it, but it is pretty lightly modded. Stock turbo/injectors, studs, BPD cooler, egr delete, and BPD FICM. I get on it pretty good here and there, but compared to the abuse my buddy's 6.0 has endured I would say it has had an easy life and he has had very minimal problems.
