Unfortunately, transmission replacements are not cheap. A 2011 Subaru Outback transmission replacement costs between $6,000 and $7,000.
Transmission replacements are one of the most costly and major replacements there are. In fact, transmission replacements are often considered a total in older vehicles.
The majority of the expense is the parts—a new transmission will cost around $5,000 or $6,000. The labor will cost around $1,000, as this is a time-consuming, intensive replacement.
