Whine From Transmission? Please Help!

So i bought a 95 Cobra and it had a slight whine that sounded like it was the trans or possibly in the rear end. i took the car to a garage to have it looked at and i was told the rear end was bad and the output bearing on the trans was as well

so i spent around 2k on a rear end rebuild which covered everything bearings limited slip diff and ring and pinion. when i picked the car up the whine had gone from slight to the loudest thing ive ever heard the noise was still a whine but when from low pitched a semi quiet to the point where it over powered the sound of the exhaust.

so my mechanic that rebuilt the rear end told me the trans was most likely bad. ok so i bought a trans but i was tapped out so i picked up a t5 on craigslist and put her in myself. i just got the car down off the jackstands i take it down the road and i still have the same whine not as loud as after the rear end rebuild but louder than it was when i first picked the car up

so did i get sold a bad transmission by some ******* on cl? id like to think not but possible or did my mechanic jack up my car? any input or past experiences from you guys is much appreciated. i paid 5400 for this thing and im already into it for almost 9k with all the repairs and parts. PLEASE HELP! i just want my pony to gallop again:-(

yeah i replaced both

throwout bearing is from ford racing i ordered a ford racing pilot bearing and it didnt come in time so my mechanic said he had a few lying around and it wasnt a big deal cause theyre all essentially the same. so yes in the t/o bearing and im not sure what he used for the pilot

yeah i get out of work at 6 eastern ill try and take a quick vid or sound clip of the noise. thanks man

it doesnt want to let me upload this damn video of the noise...sorry guys
