Classic Car Transmission Fluid

What is Transmission Fluid?

Transmission fluid is a type of lubricant that is used in manual and automatic transmissions to reduce friction and wear between moving parts. It also helps to cool the transmission and prevent the formation of sludge and deposits.

Types of Transmission Fluid

There are two main types of transmission fluid: automatic transmission fluid (ATF) and manual transmission fluid (MTF). ATF is designed for use in automatic transmissions, while MTF is designed for use in manual transmissions.

ATF is typically red in color and is formulated with detergents and anti-wear additives. MTF is typically yellow or amber in color and is formulated with extreme pressure additives.

When to Change Transmission Fluid

The frequency with which you should change your transmission fluid depends on the type of transmission you have and the type of driving you do. For automatic transmissions, it is generally recommended that you change the fluid every 30,000 to 50,000 miles. For manual transmissions, it is generally recommended that you change the fluid every 60,000 to 100,000 miles.

However, if you do a lot of stop-and-go driving or towing, you may need to change your transmission fluid more often.

How to Change Transmission Fluid

Changing transmission fluid is a relatively simple process that can be done at home with a few basic tools. The following steps will guide you through the process:

1. Gather your materials. You will need the following:
• New transmission fluid
• Transmission filter (if applicable)
• Transmission pan gasket (if applicable)
• Drain pan
• Funnel
• Wrench
2. Park your car on a level surface and engage the parking brake.
3. Locate the transmission pan. The transmission pan is usually located at the bottom of the transmission.
4. Place the drain pan under the transmission pan.
5. Loosen the transmission pan bolts and allow the fluid to drain into the drain pan.
6. Once the fluid has drained, remove the transmission pan and inspect the pan for any signs of wear or damage.
7. If the transmission filter is accessible, remove the old filter and install the new filter.
8. Clean the transmission pan and the mating surface of the transmission.
9. Install the new transmission pan gasket.
10. Reinstall the transmission pan and tighten the bolts.
11. Add the new transmission fluid to the transmission through the fill hole.
12. Check the transmission fluid level and adjust the level as necessary.
13. Start the engine and run it for a few minutes to circulate the new fluid.
14. Check the transmission fluid level again and adjust the level as necessary.

Conclusion
