Mini Cooper S Problem Report
Mini Cooper S Service Recommend for "Sealed For Life" Transmissions
Failure of the automatic transmission is common. Even though the automatic transmission is advertised as "sealed for life," our technicians recommend the automatic transmission fluid be replaced every 30,000 miles with only the approved Mini/BMW fluid. Our technicians recommend thorough troubleshooting before replacing the transmission because programming procedures can affect how the transmission shifts and there is a special procedure to refill the transmission.
