I just bought a 2001 5.9 off-road that has come with a 1740 code. I have found the code is tied to the tcc. For a few bucks I'll replace the filter,fluid and all the solenoid. My question is What is the easiest way to replace the tcc/od solenoid? Should I remove the valve body or just the thing at the end with the three torch. I know there are two springs in the second method that could make it a pita. Are there any issues with removing the valve body? I am handy but by no means a transmission expert.
