A 2013 G37 transmission replacement costs between $5,850 and $6,300, though the exact price will largely depend on the state you live in, the replacement parts you’re able to acquire, and the auto repair shop you visit.
When compared to other vehicle makes, this is slightly higher than average but fairly normal for Infinitis in general. Expect to pay roughly $4,500 to $4,850 for the parts themselves—just know that it may be possible to find cheaper options, especially if you decide to buy the parts used.
The other $1,350 to $1,450 goes towards paying for the mechanic’s labor, as replacing the entire transmission is no small feat—even the most skilled mechanics usually require at least a day to complete the procedure.
