Compression washer (seals) for the drain plugs on the transmission and convertor. Very cheap at dealer. Also, a 'dipstick tool' to set fluid level correctly - very important. Foolish to do service without it. Also, replacement plastic lock tab on cap for dipstick tube. Cap may stay on without it if o-ring inside is good. Some people have reported it came off while driving.
