I have a question for you guys regarding my Tremec TKO500 Transmission. I just finished installing my engine/transmission and drive shaft. The trans is in neutral, but when I tried to move the rear wheels, it seems like it's in gear and doesn't move. I have not yet added fluid to the hydraulic clutch, so the clutch is not in working order. Tomorrow I plan on getting the hydraulic clutch bled and working. Is this normal or is there a problem with the trans being Locked up? The trans shaft did rotate before I bolted it to the bell housing. I'm just concerned that I could damage something when I start the engine for the first time.
