I installed a FRPP aluminum drive shaft on my 2002 GT this morning. I broke the 4 shaft bolts loose with a twelve point socket and a regular hammer. Instead of using a pry bar to lock the shaft in place I just pulled the parking break and put the 5 speed in first. When I took it for a test drive I had a slight high pitched whine coming from what seems like the transmission, I'm positive that the sound wasn't there before. What do you guys think? Is it possible I damaged the tranny with the hammer blows. I had to wack the bolts pretty hard to break them loose.Maybe the output shaft or bearing? Any help would be appreciated! Thanks
