* Year and Model: The complexity of the transmission varies between Blazer models and years. Older models might be simpler and cheaper to rebuild than newer ones with more advanced electronics.
* Type of Transmission: Automatic transmissions are generally more expensive to rebuild than manual transmissions. The specific type of automatic transmission (e.g., 4L60E, 700R4) also impacts cost.
* Extent of Damage: A simple rebuild involving replacing worn parts will be far less expensive than a complete overhaul that includes replacing the valve body, torque converter, or other major components. A transmission that has suffered significant internal damage from neglect or abuse will cost considerably more.
* Labor Rates: Labor rates vary widely by geographic location and the shop's reputation. A high-end transmission specialist will charge more than a local mechanic.
* Parts Costs: The cost of parts can vary depending on the supplier (OEM parts versus aftermarket parts). Using used parts can lower the cost but may also increase the risk of future problems.
Rough Estimate: Expect to pay anywhere from $1500 to $4000 or more for a transmission rebuild on a Chevy Blazer. The lower end of this range is for simpler repairs on older models with less damage, while the higher end covers extensive repairs on newer vehicles or those with significant internal damage.
Recommendation: To get an accurate estimate, it's essential to get quotes from several reputable transmission shops in your area. Be sure to describe the problems you're experiencing with your transmission as accurately as possible so the shops can give you a fair assessment of the necessary repairs. Don't hesitate to ask for a detailed breakdown of the costs (labor, parts, etc.).
