* Fluid and Filter Change: This is the most common type of transmission service. The old transmission fluid, which degrades over time and use, is drained and replaced with fresh fluid. The transmission filter, which traps debris, is also replaced. This is preventative maintenance to keep the transmission running smoothly and extend its life.
* More Extensive Service: If the car has higher mileage or is showing symptoms of transmission problems (rough shifting, slipping, etc.), the service might involve more than just fluid and filter. This could include:
* Fluid flush: A more thorough process than a drain and fill, designed to remove more of the old fluid. However, some mechanics advise against power flushes as they can dislodge built up deposits that might not cause problems.
* Inspection of the transmission: A visual inspection might reveal worn or damaged parts that need replacement or repair.
* Seal replacement: Transmission seals can wear out and leak fluid, requiring replacement.
* Internal repairs: In more serious cases, internal components of the transmission might be worn or damaged and require repair or replacement. This is usually a much more expensive undertaking.
In short: "Transmission service" for a 2000 Impala is a broad term. To understand the exact nature and cost of the service, you need to ask the dealer for specifics. Inquire about:
* What exactly needs to be done? (fluid/filter change, flush, repairs, etc.)
* What parts will be replaced? (if any)
* What is the estimated cost?
* What are the consequences of delaying the service?
Ignoring needed transmission service could lead to more serious (and expensive) problems down the line, even transmission failure. Getting a second opinion from another trusted mechanic is also a good idea before committing to any major repairs.
