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?

does the whistling start on a lower pitch speed up and move to a higher pitch as u push the stick harder right before it moves into gear? it does this goin into second in my car when im over 40mph if i use a little force and rest it against the second gear position right before it pushes over...not positive but i think its the syco...ur sycro on the 5th gear may have gone out so therefore the car couldnt shift it in without matching revs so this may have caused u to loose the 5th gears...
