Storing a car for an extended period can have a detrimental impact on the quality of its transmission fluid. This is due to several factors that contribute to fluid degradation and potential damage to the transmission system.
Fluid Degradation Processes
- Evaporation⁚ Transmission fluid is a complex mixture of chemicals that can evaporate over time, especially in hot environments. This evaporation reduces the fluid level and alters its composition, potentially leading to friction and wear within the transmission.
- Oxidation⁚ Exposure to air and heat can cause the transmission fluid to oxidize, forming sludge and varnish deposits. These deposits can clog transmission components, hindering proper fluid flow and lubrication.
- Moisture Absorption⁚ Transmission fluid is hygroscopic, meaning it can absorb moisture from the air. This moisture can lead to corrosion of internal components, particularly in the presence of oxidation products.
- Seal Degradation⁚ The seals within the transmission can deteriorate over time, especially if the fluid has been exposed to extreme temperatures or moisture. This can result in leaks and fluid loss.
Consequences of Degraded Fluid
Degraded transmission fluid can have severe consequences for the transmission system⁚
- Increased Wear and Tear⁚ Insufficient lubrication caused by degraded fluid leads to increased friction and wear on transmission components, potentially shortening their lifespan.
- Sluggish Shifting⁚ Deposits and sludge can clog valves and other components, resulting in delayed or erratic shifting and reduced transmission performance.
- Transmission Failure⁚ In severe cases, degraded fluid can cause catastrophic transmission failure, requiring costly repairs or replacement.
Preventive Measures
To mitigate the effects of storage on transmission fluid quality, consider these measures⁚
- Regular Fluid Changes⁚ Before storage, it’s advisable to change the transmission fluid and filter. This ensures fresh fluid is present during storage.
- Top Off Fluid Level⁚ Ensure the fluid level is at the proper mark in the dipstick. If the fluid level is low, top it off with the correct type of fluid.
- Storage Environment⁚ Store the car in a cool, dry, and well-ventilated environment. Avoid storing the car in direct sunlight or extreme temperatures.
- Periodic Inspection⁚ Inspect the transmission fluid regularly during storage. Check for any signs of discoloration, odor, or deposits.
By taking these precautions, you can help preserve the quality of your transmission fluid and ensure smooth operation when you restart your car after storage.
