transverse transaxel Problem !!

[KcGsXrated]

So this is the second time that my transverse transaxel or Transmission is "messed up" on the backside of the tranny it became seperated again, i can see half of the dowl pin.... It was fine before I rebuilt the motor, and the transmission has been giving me preoblems ever sense. i was driving normal and all of a sudden it wouldnt let me shift out of gear or get into any other gears.

Does anyone know how i can keep the back side of the tranny flush with the motor, And yes all the bolts that hold it on are tight.
