i put a 91 si trannie in my 91 dx hatch about 3 months ago after i decimated the stock trannie and everything has been fine since. but tonight when i was riding around(grandma'ing it) my trannie went BANG and the car made a hard ass jerk and now gets stuck in every gear unless the car is off and not moving. also when it happened i was pulling off a green light and in the middle of a shift when it happened. my question is what happened? it snuck up out of nowhere when it happened because everything felt fine no more than 5 mins before.
