Should I Change Transmission Fluid after 100k Miles

Before finding out about when should I change transmission fluid after 100k miles, beyond 100k or earlier, first need to go through about transmission types and their mechanical system.

Most people doesn’t know exactly about too much of transmission technology and their importance of right time to change fluid oil, therefore in this topic we try to present in detail to make it more informed and right time to change fluid oil.

First Types of Transmission:

Three types of transmission are using in vehicles.

  • Manual (MT)
  • Auto Transmission (AT)
  • Continuous Variable Transmission (CVT)

Manual Transmission

The manual transmission, which is also known as a “standard transmission” or a “stick shift”, is a type of transmission that utilizes a driver-operated clutch to regulate torque transfer from the engine to the transmission.

The clutch is typically engaged or disengaged by a foot pedal or hand lever. Because they are the simplest, mechanically speaking, of the three types of transmissions, they also often have the longest lives, because there is less to go wrong.

They also often offer the best fuel economy and manual transmission vehicles are typically a bit cheaper. Some drivers even enjoy driving them more.

Auto Transmission (AT)

Auto transmission is simpler than CVT technology to understand, the car has gears which shift by itself using a fixed proportion of speed and RPM, the system called planetary gear set is the device that makes this possible in an automatic transmission.

Continuous Variable Transmission (CVT)

A continuously variable transmission (CVT), also known as a shiftless transmission, steeples transmission, pulley transmission, it’s an automatic transmission that deliver seamlessly acceleration through a continuous range of effective gear ratios or you can say without interrupting for gear shift.

Now let’s come to the point of when Should I Change Transmission Fluid After 100k Miles

Each vehicle brand manual tell schedule miles to change fluid oil which we usually don’t bother, we only do attention when we feel something is happening on to the gears, that one lead to various issues on Transmission, Most Common signs are:

Caution:

  • Avoid from being in that stage as stated above problems, because it only happens when your transmission damaged permanently due to low oil or from expired oil.
  • Those who suggest to change oil when transmission indicator symbol pop up on your dashboard then they are totally wrong, indicator only pop up when there is problem in it, such as damage, low oil sometimes only pop up when zero fluid oil therefore don’t go on that symbol.
  • 80 percent chances that transmission will not back to normal health regardless of Flush, new oil or whatever experiment your mechanic do to make it as it was, it only requires replacement.

Apart from Fluid oil, look at a best engine oil for over 100k and 200k

A little detail of which oil is better synthetic or conventional engine oil for your car.

Recommended Time to Change Oil

  • Every time you change engine oil always ask from mechanic or make sure by self that your vehicle fluid oil not leaking from underneath, however you can also diagnose this problem by checking fluid oil gauge and from your car parking garage where you can see any leakage of oil.
  • Average time to change fluid oil for all vehicles except heavy towing vehicles are from 40,000 miles to 50,000 miles, if you want your car to run smooth and fast, some brands said of at 60,000 miles, but it’s up to you, however must change oil before it being dark brown or smell like burn.

 Should I Change Transmission Fluid after 100k Miles

  • Always follow the advice of manufacturer schedule time to change oil and what grade of fluid oil would be best at a stage of oil interval.

In addition transmission fluid oil time to change depends upon weather, area and vehicle usage.

  • Weather: not affect so much
  • Area: Affect a lot, require to change oil earlier than said time by manufacturer of a vehicle is on dusty place.
  • Vehicle Usage: for vehicles who use their cars, small trucks, suvs frequently for towing than they might need to change their oil as recommended time by manufacturer, don’t lazy on this especially for these types of vehicles, however for normal vehicles you can bet on your luck, sometimes cars wouldn’t cause any problem after 100k or some having an issue under 100k.

 Be wise rather than Foolish

Verdict:

Should I Change Transmission Fluid After 100k Miles definitely not, always took the advice of manufacturer schedule maintenance time, and stated above caution and recommend time to change fluid oil.
