I have gone through 2 " bulletproof" th350's in the past year ( built with redline clutches and hardened sprags etc" and am finally going through the 3'rd one this week - I brought it in to the trans shop for a new build and can't figure out what to do... Should I have him build me a 4l60E and be done with it ( 1700.00 ) or should I wait for a 400 case ( 1200.00 ) to come available? I have a 900$ credit for the th350 coming because it has come apart 3 times -
