fluid level was almost 2 QTS low when I bought vehicle. topped it off properly [warmed up running in neutral] worked fine except for long, slow upshift out of 1st, other gears shifted fine. then without any warning, heard high pitched whine while driving and by the time I had gone 10 miles or so, it wouldn't shift out of 1st at all. would rev to near redline, then acted like it was freewheeling in neutral when i backed off throttle and resumed 1st gear when re-applying throttle. no reverse, no shift at all now. no fluid loss apparent.
