4L80e in place of 4L60e,Better or Not?? I blew my tranny a few weeks ago behind my 408 
,Im still debating either to go TH350 full manual with updated drum,TH400 with upgraded internals,or my T56 that I have lying in my room with a LS7 clutch.But kinda dont want to lose my overdrive,I was also looking of going 4L80E full manual or keep the automatic functions with the speartech harness and reprogramming.I will be sparaying a 200 shot on this motor every now and then,its my daily commute to work.I just want to do this right the first time,I dont want to go thru 4 or 5 transmissions rebuilds before I learn $ wise.What's you all's best advise and any recommendations are greatly appreciated.
