I REALLY NEED SOME ADVICE, I OWN A RED 91 FIREBIRD (5.0L 305) AND JUST ABOUT A WEEK AGO I FOUND OUT AS I WAS GETTING ONTO THE STREET AND I SORTA HALFWAY FLOORED THE PEDAL, THE TRANSMISSION MADE A NOISE. IT WAS AS IF A ROCK HIT THE CAR FROM UNDER, I CHECKED THE TRANSMISSION FOR FLUID AND TO MY CARELESS MISTAKE IT WAS LOW, I REFILLED BUT STILL THE POP OR BANG OR CLUNK OR WHATEVER IT IS STILL OCCURS IF I STEP ON THE PEDAL HARD, OTHERWISE THE TRANSMISSION IS DOING GOOD. I'D GREATLY APPRECIATE ANY ADVICE OR IF SOMEONE KNOWS WHAT THE CAUSE OF THIS IS.

THANK U

You should get under your car and see what the trans mount looks like. If it is torn or broken get a good poly one from ES.

 

i would say to check the trans mount and crossmember.
