5th gear crapped out Options

[FSX_Celica94GT]

I was driving from my friends house up to my dads work to drop off his bomex back bumper *which was cracked in like 5 different places when we got the package after waiting a month* and was driving in fifth gear just fine, then i stopped, and when i accelerated up to 40mph, i shifted to fifth gear, and i heard a grinding noise when i tried to go, i tried it again, and it still grinded, all of a sudden i couldnt use my fifth gear when i just used it 10 seconds ago. Anyone know what could have caused this? Also, my transmission makes a whistling noise through all the gears, but starts out real soft in first, but then you can really hear it in fifth, i think that might have something to do w/ my 5th gear goin out, but i dont know what the whistling noise is, any help would be appreciated thanx.
also, we're lookin at buyin a new transmission, are the transmissions from the camry's the exact same as our celicas 5sfe transmissions? if so, would it be cheaper to get one off of a camry? how much do 5sfe tranys go for usually?

guess i'll have to since ive never touched a tranny in my life lol. But its prolly the best to get a new low mileage one w/ my new low mileage engine. Lasted through 176k miles, the little trooper, especially going through 2 of my aunts kids and one of them doesnt give a s*** about anything, so im guessing hes part of this problem im having.
