Transmission fluid breaks down and gets dirty over time. If you have either an automatic or manual transmission, you need to have it serviced on schedule to make sure your vehicle continues to run efficiently. Automatic transmissions contain a maze of passages that the fluid has to pass through to keep it shifting smoothly. If you choose to neglect transmission service, those passages can get clogged up and you will start to have problems. Neglect your transmission for too long, and it will fail. If you begin to hear clanking, thumping or screeching you should come into Advanced Transmission of Denver and we will give your vehicle a free computer scan inspection.
