Default Torque converter went bad?

Yesterday I was parked, started my 95 lt1 camaro up, and heard a winding up noise from somewhere under the back rear side of the engine, luckly I had a friend with me who is a good mechanic and at first said he thought the lifters went bad inside the engine, however when I gave it a little gas, the winding up noise went away, but would come back slowly then the sound would start speeding up. He told me to put it into drive, and the noise went away and the car was able to go forward, it wasnt until I put the car in reverse or neutral that the winding up noise would start and I wasn't able to go in reverse at all. After pushing the car and getting out, there was a little winding up noise when we were driving and i let go of the gas, but it hasn't made any more of it when driving. Him and someone else told me there think the torque converter went bad.

Later that night, I tried reverse and neutral, and the noise went away, but giving it gas in reverse didn't move the car, in reverse it would just slowly move back on its own.

This morning i tested it, no wind up noise in reverse or neutral, and at first it did move back on its own in reverse. I then put it in drive, moved up a little, stopped, put it in reverse, and it doesn't move at all. I also didn't hear the same winding up noise, but rather an alot softer almost fan like spinning noise.

I also will say that before when i would put it in reverse, there would always be like a 2-4 second delay and you could really feel something in the car move/turn over before going in reverse.

Could this be the TC? How much would one cost? Don't I have to get one with a higher stall speed then my lowest rpm or something? sorry for being such a noob

Have you checked the fluid level in the transmission?

When a torque converter fails it will send metal pc all thru the transmission so to fix it you are looking at a rebuild of the trans.

This does not sound to me like a converter failer. Remember the engine and converter turn only one way. Reverse happens much farther into the transmission. The torque converter does the same thing in forward as it does in reverse the only differents is slightly higher line pressure.

Ok.

Now when i give it gas in reverse, the spinning noise will start and stay as long as im holding down the gas
