Hello,

Upon acceleration my 91 240 makes a substantial "tinny" sort of thin metallic clatter sound. If I let up on the throttle the sound mostly goes away. I initially thought it was loose exhaust bits, but after removing the thin exhaust shrouds from the header pipe and the preheat hose area the sound remains. I even replaced part of the exhaust. It is coming from the torque converter area. No other symptoms, doesn't make any sounds at idle, and has made the sound in neutral, park, and drive - all I need to do is press on the throttle - both stationary and moving. However, sometimes in park or neutral it will not make the sound (a bit inconsistent). I looked at the flex plate and the bolts are tight / no metal cracks. Fluid level is correct. Car drives fine for the time being, even on the highway.

Any ideas? My plan is to at least prepare by learning where to get a torque converter and which one I need to get.

Does anyone that has done this already know where I can buy a torque converter for the AW-70 online, and which specific one (so far there seems to be a few different types, bolt patterns, etc.)? I don't plan on visiting a pick 'n pull, I'd just like to order one online and have it here ready to go.

Thanks, Joe
