A 4L60E can hold a bit more than 400rwhp fully built (maybe 475-550 or so), don't think you need a 3/4 ton tranny for ~400rwhp...it's silly at this point.
It's 85% builder, 15% parts IMO. Shitty builds entailing not checked clearance on the clutch packs, poor valve body setup, 2-4 band clearance, overly hard/soft shifts, endplay, general slop, etc. all cause failures. You've gotta pay to play when it comes to big power, pay for a good build.
