On average, a 2013 Hyundai Sonata transmission replacement costs between $4,200 and $4,550—which isn’t exactly cheap, but still cheaper than the industry average. Ultimately, however, the exact price will depend on your state, the auto shop you visit, and a few other factors.
Most of what you’re paying for goes towards purchasing the parts themselves—a new 2013 Hyundai Sonata transmission sells for anywhere between $3,150 and $3,400, though it may be possible to find cheaper options depending on what is currently available and if you buy the parts used.
Labor costs make up the other $1,050 to $1,150, though the exact charge will largely depend on how long it takes the shop to replace your transmission—and even the fastest mechanics usually require at least a full day for this service.
