* Labor costs: This varies greatly by location (rural vs. urban, geographic region) and the specific shop (independent mechanic vs. dealership). Expect to pay anywhere from several hundred to over a thousand dollars in labor alone.
* Transmission type: Is it a rebuild of your existing transmission, or a replacement with a used or new unit? A used transmission will be cheaper than a new one, but carries more risk. A remanufactured transmission falls somewhere in between.
* Parts cost: A new transmission is the most expensive option. A remanufactured transmission is less expensive, and a used transmission is the cheapest. The cost can range from several hundred to several thousand dollars depending on the source and condition.
* Additional repairs: Often, other components related to the transmission might need attention during the repair, such as the torque converter, fluid cooler lines, or seals. These add to the overall cost.
* Shop fees: Shops may add fees for diagnostics, disposal of the old transmission, etc.
In short, you could reasonably expect to pay anywhere from $1500 to $5000 or more for a transmission replacement in a Cadillac DeVille with a 4.9L engine. To get an accurate estimate, you'll need to contact several reputable transmission shops or mechanics in your area and provide them with the specifics of your vehicle and the problem you're experiencing. Getting multiple quotes is highly recommended.
