4l60e problems Need some help please. i have 03 Silverado z71 & about a year ago transmission went out.so bought a new one frm autozone. Well its been a year & i started modifying my truck.anyways i put a cheap Amazon tc in it.well first day took off frm stop lite and b4 it shifted it started clanging and went out.so under warranty got a new transmission about 3 weeks ago and i bought a hays 3200 stall converter becuze i was camming it well i did all that got it tuned a few days ago & today i took off frm a stop.& went threw 1st on to second gear and rpms went up to like 6 grand .now when i take off rpms are going real high have to let off for it to catch .& got a message on dash saying transmission is to hot so checked cooler and its as cool as out side.but tranny is hotter then hell so i pulled line off cooler and its jst dripping out. Now when i get in it it will take off fine in 1st gear but dont last long then its back to high rpms.kinnda like if it had no fluid in it.i jst put alot of time and money in to this damn thing .can anyone tell me whats probably wrong maby the pump went out.o and 2 days b4 this happened on way to work my transmission was screaming only when idle was high but was screaming like a wet serpentine belt but when i got back in truck when i got off it wasn't so dont know if that had anything to do with its demise. I was thinking the tc is bad but its brand new too so im at a loss here if anyone has any ideas i sure would be grateful & thanks

The rebuilt units that you can pick-up at your chain auto parts stores are not a quality unit, neither are the torque converters that you are using. But it sounds like you may have broken the pump gear when installing the torque converter.
Take one of the transmission cool lines loose from the cooler, have someone start the engine and observe now much fluid comes out. A lot should come out very fast.
