Question: how much does it cost to replace my transmission?
Answer: “Ninety percent of failures are caused by items [inside the transmission] that can't stand the wear and tear of 80,000 or 90,000 miles,” Avner says. Avner says the average cost of a rebuilt transmission is $2,800 to $3,800, and the average cost of a replacement transmission is $4,000 to $8,000.
