It is similar in design to the six-speed transmission found in the 2010-2014 Outback. Subaru stopped offering the Crosstrek with a manual transmission starting with the 2024 model year. [14] This transmission is desirable for its low first gear ratio and compatibility with older Subaru platforms, such as the 3rd generation Outback (2005-2009). [15]
