Effect of engine overheating on an automatic transmission:
When the engine overheats, the following happens:
* Reduced Transmission Oil Pressure: Excessive heat causes the transmission oil to thin, resulting in a decrease in lubricant pressure.
* Damage to seals and gaskets: Heat can damage the seals and gaskets in the transmission, causing fluid leaks and system contamination.
* Clutch Burnout: Overheating temperatures can cause premature burnout of the clutches used to shift gears.
* Warping of metal components: Excessive heat can cause metal components inside the transmission, such as shafts and gears, to warp.
Consequences for the gearbox:
Overheating of the engine can lead to the following consequences for the automatic transmission:
* Gear Slip: Low oil pressure or burnt clutches can cause transmission slip, making shifting difficult or impossible.
* Difficulty Shifting: Damaged seals and gaskets can cause fluid leaks, making it difficult to shift gears.
* Warning Light Illuminates: Some vehicles have a warning light that illuminates when the transmission overheats.
*Transmission Failure: In extreme cases, overheating can cause the transmission to fail completely, requiring costly repairs or replacement.
Preventing transmission overheating:
To prevent the transmission from overheating, it is important:
* Maintain proper transmission oil level.
* Replace transmission oil and filter regularly.
* Avoid prolonged driving with high engine load (for example, on inclines or when towing).
* Immediately pay attention to any signs of overheating, such as slipping gears or difficulty shifting gears.
