Does Car Need to Be Running to Add Transmission Fluid?

Introduction

Transmission fluid is a vital part of your car’s transmission system. It lubricates the moving parts and helps to keep the transmission running smoothly.
When the transmission fluid level gets low, it can cause the transmission to slip, shudder, or even fail.
That’s why it’s important to check the transmission fluid level regularly and add fluid as needed.

Can You Add Transmission Fluid Without the Car Running?

The answer to this question is yes, you can add transmission fluid without the car running.
However, it is important to note that the transmission fluid level should be checked with the car running and the transmission in park.

To add transmission fluid without the car running, follow these steps:

1. Locate the transmission fluid dipstick. It is usually located near the back of the engine, close to the firewall.
2. Pull out the dipstick and wipe it clean with a rag.
3. Reinsert the dipstick and pull it out again. The fluid level should be between the “full” and “add” marks on the dipstick.
4. If the fluid level is low, add fluid through the dipstick tube. You can use a funnel to make this easier.
5. Check the fluid level again and add more fluid as needed.
6. Once the fluid level is correct, replace the dipstick.
