Do Cars Need a Transmission Flush Every 45,000 Miles?
The Answer is: No
Transmission flushes are not necessary for most cars and can actually do more harm than good. The vast majority of cars have sealed transmissions that do not require servicing. The fluid in these transmissions is designed to last the life of the vehicle and does not need to be changed. In fact, changing the fluid can introduce contaminants into the transmission and cause problems.
When to Get a Transmission Flush
There are a few cases where a transmission flush may be necessary:
- If the transmission is leaking fluid
- If the transmission is slipping or shifting erratically
- If the transmission has been submerged in water
How to Get a Transmission Flush
If you think your car needs a transmission flush, take it to a qualified mechanic. The mechanic will be able to assess the condition of the transmission and determine if a flush is necessary. If a flush is needed, the mechanic will use a special machine to circulate new fluid through the transmission. The machine will also remove the old fluid and any contaminants.
Benefits of a Transmission Flush
A transmission flush can provide several benefits, including:
- Improved transmission performance
- Reduced transmission wear and tear
- Extended transmission life
Risks of a Transmission Flush
While transmission flushes can be beneficial, there are also some risks involved. These risks include:
- Introducing contaminants into the transmission
- Damaging the transmission
- Voiding the transmission warranty
