The torque converter has a small flat plug with an aluminum washer that is removed with a 5(?)mm hex key.

By charge I mean "fill".

Check eBay for a manual. There are no online manuals.

My local auto supply store carries MB filters made by Fram (Part No. CH 6848), though I prefer to buy my supplies from FastLane, which is just a click away if you go to the top of this page. They not only support this forum, but they also give low competitive prices and the best service around. Talk to Phil, he'll get you what you need, especially if it's not in the online catalog.
