T-5 Transmission noise

[Titan2175]

I have a '95 Gt coupe, the car has a good deal of engine work but retained the stock T-5. Rcently the car has been making a high pitch squeak, that starts when i get on the gas in gear, but does not occur at idle. I changed the differential fluid thinking it might be the diff, which it wasnt. I also WD-40'ed the universial joint and where the trans joins the driveshaft. Neither helped. I added some grease to the universial joint, which also had no effect. The noise sounds like its coming from about 6-8 inches behind the shifter.

Any ideas?

Thanks,
Erik

does the sound happen if the car is in neutral and you rev the engine?

No it doesnt, it only happens when there is a load going through the trans, with the clutch in or in nuetral it doesnt make the noise,
