* Cost of the used transmission: This can range from a few hundred dollars for a low-mileage, well-maintained unit to over a thousand for a supposedly better one. The condition is crucial – a cheap transmission might need further repairs soon after installation, negating any savings. You also need to consider the cost of having it tested if the seller doesn't provide a warranty.
* Labor costs: This is where the price jumps. Transmission removal and installation is a major job, requiring specialized tools and considerable mechanical skill. Expect to pay anywhere from $800 to $2000 or more in labor, depending on your location (labor rates vary by region), the mechanic's experience, and the complexity of the installation (some Tahoes have more difficult transmission access). Additional labor might be needed if unforeseen problems arise during the process.
* Fluid and filter: New transmission fluid and a filter are absolutely essential. Factor in at least $50-$100 for this.
* Other potential costs: There's always a chance of discovering other issues during the installation (e.g., damaged torque converter, worn mounts). These would add to the overall cost. A shop might also charge for a diagnostic scan before and after installation.
Therefore, a reasonable estimate for the total cost would be anywhere from $1000 to $3000 or more. Getting multiple quotes from reputable transmission shops in your area is highly recommended. Be sure to ask for detailed breakdowns of costs (parts, labor, etc.) and what their warranties cover. Consider the reputation of the shop and whether they specialize in transmissions.
Important Note: Installing a used transmission is inherently risky. There's no guarantee of its lifespan, and you might end up needing another repair or replacement sooner than expected. A rebuilt transmission or even a new one might be a better long-term investment, though considerably more expensive upfront.
