1991 Acura Legend Chain sound, thick smoke and an anti lock

Transmission problem
1991 Acura Legend V6 Front Wheel Drive Automatic 149000 miles

I am noticing a chain like sound in or under the engine. It sounds like its around the front right tire but it sounds like it travels to the RR as well. Like a bike chain thats off before realigning its teeth, or between gears. There is a noticible space and power misassociation shifting between gears 1 and 2 and it seems to almost blow through 3 but I am able to accelerate and decelerate normally except for the kick/lack between 1 and 2.

Also I am noticing thicker exhaust. It isn't dark or white and I'm not burning or leaking any oil.

The anti lock break light turns on after 2 minutes, and the anti lock breaks work.
