Sunshell couldn't have been the problem as it holds in reverse, 2nd, and 4th. It is directly linked to the reverse input drum and controls motion of the rear sungear... either by the reverse input clutch coming on (in reverse) or by the band holding the reverse input housing in 2nd & 4th (actuated by one of the two servos you see in the passenger side of the trans). It breaks by stripping out the splined end holding the rear sun gear.
It's best to use the SPX/Filtran Beast sunshell and use the wider sonnax bushing for the rear sungear (you can't use the beast with the factory bushing... it'll wear it out too soon).
It sounds like there were multiple failures in the valvebody and rotating assembly to get the conditions you described.
Glad it worked out for you though.
A sunshell can fail at any time,, given they usually fail when you are gassing it in reverse.. I had two sunshells fail in the same tranny,, and after they installed a beast, it's been bulletproof! Glad they fixed your issues!
