Transmission Fluid Leaking Problems of Mini Cooper Convertible

While driving to work on hwy 270 going south between manchester rd and dougherty ferry rd in rush hour traffic sometime between 4:30 and 5:30 pm my 06 Mini Cooper Convertible was reving up as I press the accelerator but yet barely moving. Right before the the dougherty ferry exit it "kicked" into gear and began driving at about 40-50mph. I thought I may have accidentally hit the gear shifter and put it into sport drive but when I looked the gear was still in drive. So as I was traveling to work in arnold, mo the transmission would rev up and then "kick" into gear. When I got to work I explained to a CO-worker (initial "j. R. ") what happen while I was driving and we went out on our break to take a look and see if I needed transmission fluid. We were unable to find the transmission dipstick so on my laptop I tried looking it up to see where it was located. We learned that's there's a plug underneath but the transmission is "sealed for life" meaning it shouldn't really have any leaks. So I called home to let my wife to let her know that I was going to try and make it home in the morning when I got off at 6am. After driving up to hwy 270 and manchester going north at about 630am traveling at about 40 mph on 4/4/13 the car begin revviing up again whenever I pressed the accelerator. So rather than go home I headed straight for the Mini of st. Louis dealership. I got to the dealership before they opened and didn't have an appointment so they stated they would try and squeeze me in. So I went to drive the car up to the entrance to the service bay and the car was "bucking and jerking" and barely moving. Upon talking to the service department Mini I was informed that I needed a transmission and it was $8k but if I wanted to they could get me into another Mini right away. On April 9th my wife purchased a new 2013 Ford fiesta in place of the Mini.
