Three washers in tranny filter kit for SL320?
I received a transmission filter kit (94 SL320) from FastLane containing the filter, pan gasket, 2 aluminum washers of equal size, and 1 larger copper washer. The torque converter and pan drain plugs each had a aluminum washer. The new filter cartridge inlet and outlet ports each had cork washers in place. Is the copper washer extra for this application? Or am I overlooking it's home?
