Default Blew my Tranny because of a servo!!

Well here is the run down... my cam,headers,410 gear come in on monday... i take it to my dads shop and everything but the gears are installed on wednesday so i take the truck to go the exhaust done (3' full exhaust with a dynamax bullet) then after that i take it to flaco to go get it tune which ran great by the way. so the next day i take it back to my dads shop installed the 410's and then we put the servo in exactly how it is suppose to be put in. i drive around the block and its shifting pretty firm but nothing drastic to how it was shifting after flaco tuned it. so i leave from houston goin down 225 get of on the beltway and once i get on red bluff it just stops shifting. i give it a little gas in it just revs up? i pull over and oil is leaking pretty bad were the servo was put in. we look underdeath and the servo is still in place a little bulged out but the around the servo the transmission case is cracked!

basically it was a horrible friday and i have no idea why this happend? any suggestions to why this happened? bad news is im out of a truck for a couple days... good news is we are gonna go head and put a 3500 stall and look for a new tranny cause i doubt the tranny is fixable?

you didn't install the snap ring all the way in and probably cracked the tranny case.

Common error, and an expensive one.

It's not the servos fault it wasn't installed correctly. This has happened several times on here.
