T5 Borg Warner into an A body???

I have an '88 Mustang LX 5.0L, 5 speed, convertible I bought new. I can not count how many time I have power shifted the car (hold gas pedal to the floor and shift quickly). Not one single problem with the trans, it still shifts perfectly to this day. Car currently has 46,000 miles on it. I ran the car at the strip and it ran a 14.1 ET with street tires. Car has never had slicks on it and I still run the stock shifter. I don't believe the T5s aren as weak as people keep saying. Now if you shift into third like you are trying to knock the headlight out yes they will break. And they probably won't last long with a 400 plus hp V8 and sticky rear tires either. But for a mild V8 with street tires in a lighter car it should last a while.
