2003 5.9 Trans Cooler

[RamYourDaughter]

Have a 2003 2500 with 5.9 and the 48RE transmission. Found the cooler lines to be leaking so I will be replacing them and bypassing the heat exchanger on the block. I have found a Mishimoto direct drop in but it is 500 plus. I don’t believe the doorman replacement will be sufficient . Does anyone have any recommended direct drop ins ?

not sure I'm talking bout the same but on my 03 ram 2500, my mechanic found trans cool lines leaking. instead of me spending a ton, I replace the entire set of lines with high pressure 3/8" hose. with clamps. doesn't leak now. transmission cooler lines do nopt create high pressure, so hose that has 300psi/400 degrees will be perfect.
