Frequently Asked Questions (FAQs)
1. What are the seals on an automatic transmission?
Automatic transmission seals are used to contain fluid pressure and prevent leakage. They can be made of metal, synthetic rubber, or Teflon. There are two types of seals: positive seals that contain all fluid and non-positive seals that allow a small amount of fluid for lubrication.
2. How many seals does a transmission have?
A transmission typically has two main external seals: the front seal and the rear seal. The front seal is located where the torque converter mounts to the transmission case. It allows fluid to move from the converter to the transmission while preventing leaks.
3. Where are lip seals used in an automatic transmission?
Lip seals are commonly used in automatic transmissions, particularly at the point where filters assemble into the transmission. These seals ensure a proper seal and may sometimes be referred to as O-rings.
4. What happens when a transmission seal goes bad?
When a transmission seal fails, it can lead to fluid leaks. These leaks can cause damage to the transmission and potentially lead to a complete transmission failure. It is important to address seal failures promptly to prevent further damage.
5. Are transmission seals easy to replace?
While many transmission seals are inexpensive and straightforward to replace, some may require extensive dismantling to access. For example, gearbox oil seals usually require removing the entire gearbox. It is advisable to seek professional assistance for these types of seal replacements.
6. What causes transmission lip seal failure?
Excessive temperature is a common cause of transmission lip seal failure. High temperatures can result in thinner lubricating film, leading to dry running conditions. Additionally, elevated temperatures can cause cracking or blistering of the elastomer material used in the seals.
