I am a new member here. I have been reading posts for a while and decided to join and be a part of an awesome site. I have a 2002 auto, 4x4 with approx. 180,000 miles on a stock trans. The torque converter is going out, I believe. The truck has been shuttering when I push it hard. Now it is shuttering even if I am just pushing the loud pedal to pass. My question is, do I need a full rebuild? I have an edge comp box (usually run on 3x50, 4" exhaust, workhorse intake, quadzilla guages. The trans guy says he can install the 2003 (48RE) parts in my trans and make it stronger?
