Q: Reinstalled my transmission and now I hear a ticking noise.

I took out my transmission to replace a bad internal slave cylinder. I'm almost sure I put everything back correctly, but when I started it up I could hear a constant ticking noise like metal hitting metal and the noise was accelerating and decelerating with the engine. I drove it around the block and it ticked the whole time,wether i was in gear or not wether clutch was engaged or disengaged and regardless of speed. i then parked it back in my driveway. The next day when I started it there was no ticking or if there was I couldn't hear it. I began to drive the truck and still no ticking when I got to a speed of about 45 miles an hour the ticking came back. When I'm going 45 and it's ticking if I let off the gas it stops ticking and if I gas it hard it stops ticking. I'm not sure if this is possible but it almost sounds like the flywheel is hitting the bellhousing dust cover. Or maybe the starter?
