Hey guys, I've got a 71 bronco, with a C-4 that was freshly rebuilt not to long ago, with the rebuilt i had them install a manual valve body. well the other day i take off from a light and shifted it hard at 5k rpm and it made a big bang and came to a stop, now the only gear i have is park, the truck still runs fine, I pulled the tranny out and the input shaft wasn't broken nor was the fluid burnt, there wern't even a metal shaving in the pan. So now i am stuck, what could of happened and how can i fix it?

Thank you

 

is it possible there is nothing wrong with the trans, and you blew the rear???

 

Well after the bang, I tried, putting it in 4x4 and it still wouldn't move, So thats why i'm thinking its the trans, Any other input would be great.

 

ok. it could also be the transfer case.

 

or maybe it's the torque converter

 

without tearing into it, its hard to say, it could be anything.
