The 6L45 and 6L50 transmissions are six-speed automatic transmissions that were manufactured by General Motors. These transmissions were installed in various BMW models, primarily in mid-engine vehicles.

• The 6L45 was installed in BMW models with less powerful engines, such as:
  • BMW 1 Series (E82, E88, E87) with four-cylinder engines (e.g. 118i, 120i).
  • BMW 3 Series (E90, E91, E92, E93) with four-cylinder engines (e.g. 318i, 320i).
• The 6L50 was used in models with more powerful engines:
  • BMW 3 Series (E90, E91, E92, E93) with six-cylinder engines (e.g. 325i, 330i).
  • BMW X1 (E84) with six-cylinder engines (e.g. xDrive28i).
  • BMW 5 Series (E60, E61) with smaller engines (e.g. 525i).

These transmissions provided smooth shifting and good fuel efficiency, which was important for cars with moderate power characteristics.
