1994 GMC k1500 Transmission Squeak?

Well after driving it for a little over a week, I dropped the pan and the oil still looks good so I'm assuming the transmission is fine for now. Thanks for all the help @NickTransmissions Side note, if it is wearing on the clutches more than it should, is there any adjustment that could be...

Hi I have a 1994 gmc K1500 240K km. Had a rebuilt transmission about 20000km ago. I just noticed a squeaking sound coming from either the transfer case or the transmission. I put it in neutral and rotated the driveshaft by hand. It squeaks only when its rotating forward, not in reverse. Cant...
