Effects Of Burnt Transmission Fluid On Transmission

Transmission fluid works as a lubricant and keeps the transmission’s internal components running smoothly. Over time, heat generated during normal transmission operations can break down transmission fluid resulting in what’s known as ‘burnt transmission fluid’. When the transmission fluid burns, it becomes thick and loses its lubricating properties.

Here is the impact of burnt transmission fluid on the transmission:

  • Incorrect shifting: The transmission relies on properly flowing fluid to regulate the shifting’s timing and smoothness. Burnt transmission fluid can cause shifting to become delayed or harsh, causing your vehicle to jump or jolt unnaturally.
  • Slippage: The lack of lubrication caused by burnt fluid can make the clutch plates slip, causing gears to grind and producing a friction-like sound. This can cause the vehicle to fail to stay in gear, decrease its speed and even reduce power.
  • Overheating: When the transmission starts slipping, it works harder to compensate for the problem, which can lead to overheating. Overheating can cause other transmission components to break down or even fail prematurely, requiring costly repairs.

Impact Of Varnish And Deposits On Transmission

Burnt transmission fluid creates varnish and deposits on the transmission’s internal areas, leading to various problems. Here are the impact of varnish and deposits:

  • Clogs: Burnt transmission fluid creates particles and deposits that can build up clogging the hydraulic system of the transmission, which can lead to more significant and costly issues over time.
  • Sticky valves: Varnish formations and deposits can also affect the valves’ operation responsible for the regulation of the transmission fluid’s pressure. Due to stickiness, valves fail to function as per the requirement, causing the transmission to slip.
  • Heating the transmission: Varnish deposits can trap heat inside the transmission, leading to defective functioning and poor performance.

Irrespective of whether you’re experiencing slip or poor performance, you must always be vigilant when it comes to transmission fluid and its maintenance. By being proactive about your vehicle’s health and reacting promptly to any mechanical issues, you can save money and make your car more reliable.

Burnt transmission fluid can cause transmission slipping and additional mechanical issues. By understanding the effects of burnt transmission fluid and varnish/deposits on transmission, you can take the right steps towards maintaining your vehicle’s overall health. So, make sure to keep an eye on your vehicle’s transmission fluid levels and service it regularly to avoid such issues.
