The chart on MyMopar.com is for 904 and 727 transmissions only and not even complete for them. I have ran into some transmissions that didn't show up on it and they were made in the same time frame as the chart covers. It's still quite handy though as there is not much published on transmission numbers. I tried a search for the one you listed and it does show it's a A500. I can't tell the year though. Is it the one Paul has listed for sale?
