If it's not the drive chain, what else might be causing the noise?
Here is something I found on Wiki*
How can you remove a transmission from a 1997 Chevy Lumina at home to replace the drive chain inside?
In: Chevy Lumina [Edit]
I am kind of leery on anwsering this question, because if you aren't sure how to pull the tranz, I don't think that there is any reason that you need to be inside of it, but here it goes. I belive the you should be able to get enough clearance by removing the drivers side frame rail, and tilting the engine/tranz combo. Drain the tranz, pull the left axle, and pull the side cover. There you will be looking at the valve body. Pull the pump, shaft, harrness, and pressure switch assy. Then come the valve body and seperator plate. (Watch for falling checkballs) Dissconnect the manual valve, and unbolt the Channel Plate. When removing the channel plate the three accumutlator springs may fall out. If they dont remove the springs. You will need a 2 jaw puller to remove the output shaft sleeve. After removing the sleeve, pull the driven and drive gears out, and any pieces of chain that you might seeMake sure every thing turns freely and doesn't have excessive play, and make sure nothing got too hurt from the chain breaking, install new chain and gears, new output shaft sleeve, and reassemble. Drop oil pan, install new filter, flush cooler, refill with oil, and give it your best blessings. I would however recommend an overhaul, but the choice it yours.
