True just curious if a bad torque converter can cause metal like that looks like copper bushings mixed with some steel
It can. Or it can be from the old trans, worked it's way into the old convertor, and then worked it's way back out into the rebuilt trans.
A long time ago I had a 65 mustang. Talk about being a newbie. I thought those things sticking out the side of the c4 were drain plugs. Wrong, they were the band adjustments. It was slipping badly after that.
So a guy I knew had a good used c4. Got it cheap, got a neighbor to help me put it in place, it ran ok but I could not see out of the rearview mirror, something was out of balance. Looked the torque convertor over, I could see a spot welded place with nothing there, I think a balance weight must have come off.
So I go get the old torque convertor from the old transmission, and swap it in myself. I got two long all-thread rods, screwed them in either side, and dropped it down and slid it back on the rods enough to take the torque convertor out. Put it back in, patting myself on the back, went to start it and the starter sounded terrible, but it started. I got under it while it was running without the inspection plate on it, it was wobbling around like crazy. I had bolted the torque convertor back in place without making sure the drain plug for the convertor was in the hole in the flexplate. I said I was a newbie didn't I?
Well the vibration was gone, seemed to shift fine, except reverse hesitated and made a buzzing noise. It got worse and worse.
So I found another used c4 to swap in. Took it down to my Dad's and he helped me put it in. I hadn't learned my lesson yet, and used the old torque convertor again. But when we went to bolt it up it lacked about 3/4 inch mating up to the 302. My Dad with a little more experience said we need to reverse course, something is not right. That is when we pulled it all back apart, and he looked down in the convertor and saw a mysterious washer floating around in the torque convertor, sort of chewed up. So I need a new torque convertor.
Go down to a shop local to my Dad's place, there is a old guy who had been working on these trannys for years. I told him the problem and he asked what year trans I had bought, I told him a 1973. He said Ford had changed the pump driveshaft size, and that was the reason I would not go in all the way. He even showed me the two different shafts, you could hardly tell the difference. He sold me the correct rebuilt convertor.
Put it all together again (by now I am a expert and taking this thing out and putting it in place) and everything is working, and has been working for 30 years, I still have the car with that tranny in it.
So yes, the torque convertor can go bad inside and mess things up.
