th350 accumulator piston cover leakage

[R72K5]

got a th350 that for some reason even after installing a new o ring it is badly leaking out the accumulator pison cover, as if is just too much pressure behind it or soemthing, leaves a trail on the road driving it,


anyoen have any ideas ??

the kid is a retard and has railed the truck a few times run it sideways on pavement, maybe he broke something especialyl since its a 2.73 ratio truvk, thats really super hard on tranny and driveline and mounts i know, so i dunno,


thanks
