how about torque converter? its a slow clunk. I had it in park, clunked while idling. I reved the engine to about 2k rpm and there was no clunking. I kept it at 2k for a few seconds and no clunking. once back at idle it starts clunking. When I started the car there was a bunch of clunking then goes to slow clunking. I put it in drive and as I was going through the gears the clunking became repeatedly and louder. I also have been noticing when I punch it around 60 and once the power hits I feel and grinding feel under the car. not much for a noise. So I was thinking torque converter

What would I be looking for with taking off the timing cover?
