I had my transmission rebuilt Jan '10. I had a BD torque converter installed, updated (older style) parts put in, and shift kit. I've done 10psi boost launches with no problems. Any more than that I would have started burnin' rubber. I wouldn't be running a tune over 75-100hp rated on a stock transmission if you want to keep that rebuild a couple of years down the road. Only thing left I want to do to it is the 6.0 transmission cooler, but I don't tow much so not a big concern right now.
Biggest reason why I have heared why JW and BTS come highly reccomended is because they cover the warranty (BTS is 3yr) with a modiified truck. I have also heard Brian will repair the transmission free outside of of the 3yr warranty....what's the point of having a warranty then??? The local transmission shop here rebuilt my transmission for $2100 and covered it with my mods with 1yr warranty.
