How much does it cost to replace a transmission in a 2015 Chevy Silverado?
Typically, replacing the transmission in a 2015 Chevy Silverado costs about $3,000 to $6,000 installed, with higher prices if you opt for a brand-new OEM unit or if additional components must be replaced.
What affects the price
Several factors drive the final bill. The choice between a rebuilt/remanufactured transmission and a brand-new OEM unit, the specific transmission model used in your truck, regional labor rates, and the need for ancillary parts or repairs all influence the total cost.
Transmission configurations and options (2015 Silverado context)
GM offered several transmission options for the Silverado in this era. Costs vary depending on whether the vehicle has a 6-, 8-, or other automatic transmission configuration, as well as whether the unit is rebuilt/remanufactured or new from the dealer. The exact model of transmission and drivetrain (2WD vs 4x4) can shift pricing due to different parts and installation time.
Below are typical price ranges you can expect for installed replacements based on common choices. Prices assume standard labor rates and do not include state taxes or any additional repairs.
- Rebuilt/remanufactured transmission installed: roughly $2,500–$4,500
- Brand-new OEM (dealer) transmission installed: roughly $4,000–$8,000
- Used/remanufactured transmission from salvage or non-OEM source installed: roughly $1,800–$3,500
- Additional parts and services commonly bundled with replacement (torque converter, fluids, filters, cooler lines, wiring, and calibration): $200–$1,000+ depending on what’s needed
In practice, most customers see totals in the middle of these ranges, with dealership installations tending toward the higher end and independent shops offering more competitive labor rates. Regional cost differences, warranty terms, and whether auxiliary items (like a new torque converter or cooler lines) are included can shift the final figure.
How to save and what to ask
To avoid surprises, follow a structured approach when shopping for a replacement:
- Get multiple, written quotes from both independent shops and dealerships for the same scope of work.
- Ask what’s included in the price: core charge, torque converter, transmission fluid, filters, gaskets, cooling lines, and software calibrations.
- Inquire about warranties on the transmission itself and on labor (common protections range from 12 months to 36 months).
- Consider the trade-off between a rebuilt/remanufactured unit and a new OEM transmission, factoring in long-term reliability and warranty.
Choosing a shop with a solid warranty and transparent pricing can save money and prevent future headaches should any issue arise after installation.
What to expect during the replacement process
Most installations begin with a diagnostic assessment to confirm the transmission issue and to rule out related problems (such as cooling system failures or wiring concerns). The old transmission is removed, the new or rebuilt unit is installed, and the system is refilled with the proper fluid. A series of tests — including a road test and a software calibration check if applicable — verify proper operation before the vehicle is returned to the customer. The exact timeline depends on shop workload and the vehicle’s configuration.
Summary
For a 2015 Chevy Silverado, plan for a replacement cost in the general range of $3,000 to $6,000 for rebuilt or remanufactured units and $4,000 to $8,000 for a brand-new OEM transmission installed. Costs vary by model, drivetrain, region, and whether additional components are required. Shop selection and warranty terms are important levers for managing overall expense and peace of mind. Always obtain multiple quotes, confirm exactly what’s included, and consider long-term reliability when choosing between rebuilt and new transmissions.
