The reason I began this thread begins at page 9-10 of the owner's manual, which states fluid capacities for the MIEV. Included on that page is transmission fluid type DIAMOND ATF SPIII. Plus in the warranty/maintenance PDF version at page 21 (PDF) and page 18 hard copy under regular maintenance schedule, the book calls for a check transmission oil level and condition every 12 months or 15,000 miles. To me that implies a "dipstick" to check. Obviously, there isn't such a dipstick, and I am guessing the gearbox is located in the electric motor room located at the rear of the MIEV. By the way, the owner's manual and maintenance manual never do call for a drain/replacement of the transmission fluid.
