Alright boys I'm at a loss. So two weeks ago i was doing a sick nasty pull and a loud *** shuddering and kind of grinding noise happened from my car and i lost all power. The engine was still running but the wheels were not. I managed to coast it into a parking lot and while the car was rolling i heard a ratcheting plastic sound very rhythmic like. I get it back to my house and I lift the car up and i put it in gear and rev it and the wheels start turning. So i drop it and take it around the block and i give it a little bit of gas and it gets knocked out of gear and won't go move. When i'm in drive and give it gas i can see the dash telling me that i'm changing gears but the cars not moving. so I pull the transmission out and find some interesting stuff. There's some wear along the outer diameter of the torque converter which looks pretty sus. Also whenever i turn the tranny by hand it makes the same noise as when the car was rolling. Some background info, my car would shudder a little bit around the 2-4 shifts and around 20-40mph when just easing up to speed.
Here's a link to the sound it makes when rotated
W204 C200, BMW E30 M3, 1980Gt Mini, Toyota Corona, KTM 200 EXC.
I think the superficial scratches on the outside of the torque converter housing are the least of your worries must be something going adrift internaly, also I think you were rotating the converter backwards not sure if that make any difference?
