What are a few common issues with the automatic transmission in the BMW 1 Series?

The BMW 1 Series has been facing issues with its transmissions, particularly in the 2011 models. Some owners have experienced problems such as the need to replace the oil pan and shifter, along with various stalling and gear issues with the 7-speed automatic transmission. These failures often occur at low mileage, with some occurring as early as 10,000 miles. Repairs have included replacing leaking O-rings and gaskets, while a software update has helped with erratic idling. Other reported issues include cracks in the shifter seals, clutch rattle, and the need for wiring harness replacements. One Technical Service Bulletin (TSB) addresses problems with the 8-speed shiftable automatic RWD transmission by recommending cleaning and clog removal. The cost of replacing the transmission pan gaskets alone can range from $450 to $500 in parts and labor if not covered under warranty.
