Most problems with the automatic transmission result because Mini manufacturers say that their transmissions do not need fluid changes. This is not accurate. If you do not change the transmission fluid regularly, it will cause it to fail early. Changing the transmission fluid every 30,000 to 40,000 miles will save thousands of dollars in repairs. The CVT transmissions installed before 2008 should have regular oil changes. The 5 speed automatic transmissions used on most Minis are much more reliable. If the transmission warning light shows a ! then it’s in limp mode, you can drive at a reduced speed to have the transmission checked. If there is a temperature symbol (thermometer) in the middle do not drive.
