The very crucial aspect of maintenance your jeep is checking the transmission fluid regularly. Whether you have a manual or automatic transmission, keeping an eye on your Wrangler’s transmission fluid is essential for optimal operation.
In this article, we will cover the steps for checking the transmission fluid on both manual and automatic transmissions for Jeep Wrangler.
Jeep Wrangler Manual Transmission Fluid Check:
The manual transmission in a Jeep Wrangler requires a special type of transmission fluid called “manual transmission fluid” or “gear oil.” It is important to use the correct type of fluid for your Wrangler’s manual transmission. Checking the fluid level in a manual transmission is a straightforward process that can be done in a few simple steps.
Tools Required:
- A socket wrench
- A jack and jack stands
- A funnel
- A container to catch excess fluid
- The correct type of manual transmission fluid (check your owner’s manual for specifications)
Step 1: Park the Jeep on a level surface
Before checking the transmission fluid, make sure that the Jeep is parked on a level surface. This ensures that the fluid level is accurate and not affected by the slope of the ground.
Step 2: Locate the transmission fluid dipstick
The manual transmission fluid dipstick is usually located near the back of the engine, on the passenger side. It has a yellow handle and is marked with “Transmission Fluid” on the top.
Step 3: Check the fluid level
Once you’ve located the dipstick, remove it and wipe it clean with a rag. Then, reinsert the dipstick and remove it again. Check the fluid level by looking at the markings on the dipstick. The fluid level should be between the “Full” and “Add” marks. If it’s below the “Add” mark, you need to add more fluid.
Step 5: Add Transmission Fluid (if needed)
If the fluid level is low, use a funnel to add transmission fluid until it reaches the bottom of the fill hole. Be sure to use the recommended type of transmission fluid for your Jeep Wrangler.

Manual Transmission Fluid low Symptoms:
If the manual transmission fluid level in your Jeep Wrangler is low, you may experience a range of symptoms, including:
- Gear shifting problems: Low transmission fluid levels can cause difficulty shifting gears or cause the transmission to slip out of gear. This can make it harder to accelerate, decelerate or maintain speed.
- Strange noises: Low transmission fluid can cause the gears to grind or make strange noises when shifting. This is a sign of potential damage to the gears and transmission components.
- Transmission overheating: Low transmission fluid levels can cause the transmission to overheat, which can lead to permanent damage if not addressed quickly.
- Burning smell: A burning smell coming from the engine or transmission can indicate low transmission fluid levels, which causes the gears to grind and create excess heat.
If you notice any of these symptoms, you should check the transmission fluid level immediately and add fluid if necessary.
Jeep Wrangler Automatic Transmission Fluid Check:
Once you’ve added enough transmission fluid, replace the fill plug and tighten it with a wrench or ratchet.
The automatic transmission in a Jeep Wrangler also requires a specific type of transmission fluid. Checking the fluid level in an automatic transmission is slightly different from checking a manual transmission, but it is still a relatively simple process.
Tools Required:
- A socket wrench
- A jack and jack stands
- A funnel
- A container to catch excess fluid
- The correct type of automatic transmission fluid (check your owner’s manual for specifications)
Step 1: Park the Jeep on a level surface and engage the parking brake. Place the jack under the vehicle and raise it high enough to safely crawl underneath.
Step 2: Locate the automatic transmission fluid dipstick. It is typically located on the passenger side of the engine compartment and is marked with a red handle.
Step 3: Start the engine and let it run for a few minutes to warm up the transmission fluid. This will give you a more accurate reading of the fluid level.
Step 4: With the engine still running, remove the dipstick and wipe it clean with a lint-free cloth.
Step 5: Reinsert the dipstick and remove it again. Check the fluid level on the dipstick. If the fluid level is below the “FULL” mark, you will need to add more fluid.
Step 6: Using a funnel, slowly pour the correct type of automatic transmission fluid into the transmission through the dipstick tube. Check the fluid level again with the dipstick to ensure it is at the correct level.
Step 7: Replace the dipstick and lower the vehicle off of the jack stands.
Safety Precautions:
When working with transmission fluid, it is important to take the proper safety precautions to avoid injury or damage to your Jeep. Here are some tips to keep in mind:
- Always wear gloves and safety glasses when handling transmission fluid.
- Make sure the Jeep is parked on a level surface and the parking brake is engaged.
- Always use the correct type of transmission fluid for your Jeep’s transmission. Consult your owner’s manual or a certified mechanic if you are unsure.
- Be careful not to overfill the transmission with fluid. This can cause damage to the transmission and other components.
- Dispose of used transmission fluid properly. Many auto parts stores and service centers offer fluid recycling services.
- If you notice any leaks or other issues with your Jeep’s transmission, have it inspected by a professional mechanic as soon as possible.
How Much Transmission Fluid to Add if Empty?
The amount of transmission fluid needed to fill an empty Jeep Wrangler transmission can vary depending on the year and model of your vehicle, as well as the type of transmission fluid recommended by the manufacturer.
In general, a Jeep Wrangler with a manual transmission may require approximately 3 – 3.5 quarts (2.8 – 3.3 liters) of transmission fluid when completely empty, while a Jeep Wrangler with an automatic transmission may require approximately 8 – 10 quarts (7.6 – 9.5 liters) of fluid when completely empty.
Can you Check Fluid on Manual Transmission?
Yes! you can check fluid on manual transmission and the guide of checking it properly is mentioned above in detail.
Can you Start an Engine without Transmission Fluid?
Technically, you can start an engine without transmission fluid, but it is not recommended. The engine will start and run, but the transmission will not function properly without the necessary fluid.
The transmission fluid is responsible for lubricating and cooling the transmission’s moving parts, including the gears, clutches, and bearings. Without enough fluid, these components can quickly overheat and wear down, potentially leading to permanent damage to the transmission.
Why Check Transmission Fluid when Engine is Running?
It is recommended to check the transmission fluid in a Jeep Wrangler when the engine is running because the transmission fluid needs to be at operating temperature to get an accurate reading. When the engine is running, the transmission fluid is circulated throughout the transmission and reaches its normal operating temperature. This is important because the level and condition of the fluid can vary depending on the temperature.
If the transmission fluid is checked when the engine is not running or when it is cold, the reading may not be accurate, leading to overfilling or underfilling of the fluid. This can cause damage to the transmission and affect its performance.
Conclusion
Checking the transmission fluid in your Jeep Wrangler is an important part of regular maintenance. Whether you have a manual or automatic transmission, the process is relatively simple and can be done with a few basic tools. Be sure to take the necessary safety precautions when working with transmission fluid and always use the correct type of fluid for your Jeep’s transmission. By keeping your transmission fluid at the correct level and replacing it as needed, you can help ensure that your Jeep Wrangler continues to run smoothly for years to come.
