A LOT OF PEOPLE DONT KNOW BUT THEIR IS A STRONG AND WEAK T5 TRANS.THE WAY TO TELL WHITCH ONE YOU HAVE IS TO LOOK AT THE FRONT LOWER SHAFT BERING.DON'T WORRY YOU DON'T NEED TO TAKE IT APART,BUT IN MOST CASES YOU CAN'T SEE IT WITH THE TRANS IN THE CAR,THE BELL HOUSING MUST BE REMOVED.ANY WAY IF THE BERING LOOKS LIKE A FREEZ PLUG DROVE IN BACKWARDS IT'S WEAK,IF IT'S A TWO TONE TIMKEN BERIKG IT'S STRONGER.I DON,T KNOW HOW MUCH BUT I CAN SAY THAT I WENT THRU 3 OR 4 OF THE WEAK ONES BEFOR I FOUND OUT THIS DIFRENCE.THE STRONGER ONE I HAVE NOW HAS OUT LASTED ALL OF THE OTHERS COMBINED.
