Tranny Flush
being a 97 you Should, or @ least May still have a torque converter drain as well as a pan drain.. turn the TC either w/ the crank nut or a large screw driver till the drain comes around.. both drains are 5mm. Open them

Drop the pan, clean everything, I'd pick up a trans pan magnet from the dealer JIC you don't have one..
have 8 qt's of MB 722.6 fluid on hand as well as a new filter and gasket.
Clean, Clean, Clean everything as best you can while it's apart...
You'll also need the dipstick took to check the level as your car will not have a trans dipstick..you can find them on ebay for 40$ or so..handy thing to have it you like to DIY.
