MINI Cooper Transmission Axle Seal for most MINIs. This will solve the fluid leaking problem on most Gen 2 cars, that we have noticed more frequetly, here at the shop. This seal will fit most cars, other than Gen 1 S cars, you can find that seal here: inner & outer. This will fit the inside axle seal for most MINI's and the outside axle seal for some (see below chart).
This is a semi-easy job, that should take about an hour. It's handy to have a seal install tool when installing this seal into the Gen 2 cars. It's a very tight fit to the transmission, and you want the seal to go in straight. Do not bend the seal while putting it in. This is also a good time to also do a transmission flush to make sure the level is correct. Put in some quality fluid!
