Transmission Noise

I have a 1987 GTA with a 700R4 transmission it shift great but it develop a rubbing noise only in drive and increases with speed. No change when I pull the TV cable. I change the fulid and tried 2 bottles of lucus honey teatment and no change. I have taking the rear tail of the trans off and by turning by hand it make a sqeaking nosie. So I confirm it no the driveshaft or rear end. I'm thinking it a be a internal bearing or bushing. Any help, ideas or suggests would be greatly appreciated. Don't what to take trans out of car.I haved the car for two years and it just started making the noise. It doesn't may the noise in park or reverse. the sound only increase with speed not RPM's.I check the pressure reading and they are as follow
park 45lbs.
R 90lbs
N 45lbs
OD 45lbs.
D 45lbs.
2 160-170lbs vibrating
1 160-170lbs vibrating
park just pull TV cable 155 release drop to 75 and back to 155lbs.
the mount is in good shape.
I have the car up on jacket stands with drive shaft and tail end off and by turning the out put shaft of the transmission by hand it make a screaching noise.
Could a clogged filter cause this problem??
