* Location: Labor rates differ dramatically by geographic location (rural vs. urban, state to state).
* Shop Type: Independent repair shops typically charge less than dealerships. Dealerships often have higher overhead.
* Mechanic Experience: A more experienced mechanic might charge more per hour.
* Complexity of the Repair: Unexpected issues discovered during the repair (e.g., rusted bolts, damaged surrounding components) can add to the labor time. A transmission replacement is a major undertaking.
Estimate Range:
While it's impossible to give a precise number, a *rough* estimate for labor *could* range from $800 to $2000 or even more in the US. The transmission replacement is the bulk of this cost. Replacing the motor mount is a relatively smaller job in comparison.
Recommendation:
To get an accurate estimate, contact several independent repair shops and dealerships in your area. Provide them with the specifics (2000 Buick Century, 3.1L engine, right motor mount and left transmission replacement). Ask for a detailed breakdown of the labor and parts costs. Compare their quotes carefully before making a decision. Be sure to ask about warranties on labor and parts as well.
