DIY Tips for Changing Your Vehicle’s Transmission Fluid After 100k Miles

1. Check your owner’s manual to determine the type of transmission fluid recommended for your vehicle.

2. Park your vehicle on a level surface and ensure that the engine is off and cool before beginning work.

3. Locate the transmission dipstick and remove it from its tube, then wipe it clean with a rag or paper towel. Reinsert the dipstick into its tube and pull it out again to check the fluid level (remember that it’s bad to have too much transmission fluid in your car, too); if necessary, add more fluid until it reaches the “full” mark on the dipstick.

4. Place a large drain pan beneath your vehicle’s transmission pan, then loosen and remove all of its bolts with a socket wrench or screwdriver (depending on their type). Carefully lower the pan to allow any remaining fluid to drain into the pan; once drained, replace any gaskets or seals as needed before re-installing it onto your vehicle using new bolts (if necessary).

5. Refill your transmission with fresh fluid using either an oil pump or funnel; be sure not to overfill as this can cause damage to internal components in some vehicles. Once filled, start up your engine and check for any leaks around where you replaced/refilled fluids – if none are present, you should be good to go.

6. Finally, take note of how much new fluid was added so that you can keep track of when future changes are due (usually every 30k miles).

The Cost of Replacing or Refilling a Vehicle’s Transmission Fluid after 100K miles

The cost of replacing or refilling a vehicle’s transmission fluid after 100,000 miles will depend on the make and model of the vehicle, as well as the type of transmission fluid used. Generally speaking, it is recommended that transmission fluid be replaced every 30,000 to 60,000 miles. You can learn more in our guide on the cost of a transmission fluid change.

However, if a vehicle has reached 100,000 miles without having its transmission fluid changed or refilled, it is likely that more extensive work may be required. Replacing the entire transmission system can cost anywhere from $1,500 to $4,500 depending on the make and model of the car. In short, it’s far costlier than changing the transmission fluid.

This includes labor costs for removing and reinstalling the new parts as well as any necessary gaskets or seals. If only a portion of the system needs to be replaced due to wear and tear over time (such as an individual component), then this could cost significantly less than replacing an entire system.

Refilling a vehicle’s transmission fluid typically costs between $100-$250 depending on how much fluid is needed and what type of fluid is being used (synthetic vs conventional). It should also be noted that some vehicles require special types of fluids which can increase overall costs significantly.

In addition to these costs associated with replacing or refilling a vehicle’s transmission fluid after 100K miles, there are also other potential expenses such as diagnostic fees for determining what repairs need to be made in order for your car’s performance to improve again after reaching this milestone mileage mark.

Ultimately it is important for all drivers who have reached this point in their car’s life cycle to consult with their mechanic about what repairs are necessary to ensure their safety while driving going forward.
