Transmission Pan Fluid Capacity

The 42RLE transmission fluid capacity is 8.8 quarts (8.5 litres) when dry and holds approximately 4 quarts when drained via a pan drop. This transmission fluid is specifically designed for select Jeep vehicles and it is important to use the correct type of transmission fluid to ensure the proper operation of your Jeep's transmission.

The 42RLE transmission fluid capacity with the torque converter is 8.8 quarts

The 42RLE transmission is a four-speed automatic transmission developed by Chrysler and commonly found in Jeep Wrangler models. It is very particular about its transmission fluid, requiring ATF+4. This fluid is a full synthetic and must be labelled as such.

A complete fluid change will require just under 9 quarts of fluid. However, a simple pan drop and filter change will only need about 4 quarts. It is important to note that a pan drop will not include the volume in the torque converter and cooler lines. Therefore, it is recommended to do a complete fluid change to ensure the entire system is flushed and refilled with fresh fluid.

It is also important to regularly check the fluid condition and watch for any signs of wear or damage. The transmission fluid and filter in the 42RLE should be changed every 30,000 to 60,000 miles to keep the transmission in good condition. Additionally, the transmission fluid pressure sensor and pressure switch should be checked and replaced if necessary, typically after 25,000 miles or when changing the oil.

A simple pan drop and filter change requires 4 quarts of fluid

The 42RLE transmission pan is an automatic transmission system that requires specific ATF+4 fluid. It is very particular about its fluid, and only ATF+4 should be used. This is because the transmission system is designed to work with the specific friction modifiers and additives in ATF+4. Using a generic ATF or a "super" ATF that claims to be compatible with ATF+4 can damage the transmission.

For a simple pan drop and filter change, you will need about 4 quarts of ATF+4 fluid. This process will only change the fluid in the transmission pan and will not include the fluid in the torque converter and cooler lines. A complete fluid change, on the other hand, requires just under 9 quarts of fluid.

It is important to note that the 42RLE transmission system is sensitive to the type of fluid used, and it is recommended to only use ATF+4 fluid for both simple pan drop and filter changes as well as complete fluid changes.

A complete fluid change requires just under 9 quarts

The 42RLE transmission is a four-speed automatic transmission developed by Chrysler and commonly found in Jeep Wrangler models from 1997 to 2006. When it comes to fluid capacity, there are different figures depending on the type of fluid change being performed.

Pan Drop and Filter Change

For a simple pan drop and filter change, you will need approximately 4 quarts of ATF+4 fluid. This type of fluid change will only replace a portion of the total fluid in the transmission system.

Complete Fluid Change

For a complete fluid change, you will need just under 9 quarts of ATF+4 fluid. This involves replacing all the fluid in the transmission, including the torque converter and cooler lines. It is important to note that the 42RLE transmission is very specific about its ATF fluid. It must be ATF+4, and the bottle should clearly state this in big letters on the front label.

While a pan drop and filter change are easier and less messy, they only replace about half of the fluid in the transmission. Over time, the fluid in the torque converter and cooler lines can break down and degrade, leading to transmission issues. Therefore, it is recommended to perform a complete fluid change to ensure that all old fluid is removed and replaced with fresh, clean fluid. This will help maintain the transmission's performance and longevity.

It is generally recommended to change your transmission fluid and filter every 30,000 to 60,000 miles. However, some sources suggest that you can go up to 100,000 miles without a fluid change. It is important to check your vehicle's owner's manual for specific recommendations and to regularly inspect your fluid for any signs of wear or damage.

Benefits of Regular Transmission Fluid Changes

• Prolong the life of your transmission by reducing wear and tear on internal components.
• Improve fuel efficiency by ensuring smooth and efficient gear changes.
• Prevent overheating by maintaining optimal fluid condition.
• Avoid costly repairs by catching potential issues early.

The transmission fluid must be ATF+4

The transmission fluid for a 42RLE transmission pan must be ATF+4. This is because the 42RLE is very particular about its transmission fluid. It is not enough for the fluid to be a generic or "super" ATF that claims to be compatible with ATF+4. It must be ATF+4.

ATF+4 is a synthetic transmission fluid designed specifically for Chrysler-designed transmissions. It is a hydraulic fluid used in the transmissions of passenger cars, trucks, and sport utility vehicles. It is backward compatible for service fill where Chrysler ATF+3, ATF+2, or Type 7176 ATF is called for in all applications in transmissions, power steering systems, and hydraulic systems. It is fully approved by Chrysler for all brands.

When changing the transmission fluid in a 42RLE transmission pan, it is important to note that a simple pan drop and filter change will require about 4 quarts of ATF+4. For a complete change, you will need just under 9 quarts.

It is also recommended to clean the pan when changing the transmission fluid. Additionally, it is a good idea to change the other fluids, such as the transfer case (which also uses ATF+4) and the front and rear differentials.

When choosing an ATF+4 fluid, there are several options available, including Mopar ATF+4, Pennzoil Platinum ATF+4, and Valvoline ATF+4 Full Synthetic Automatic Transmission Fluid. It is important to follow the manufacturer's recommendations and change the transmission fluid at the specified intervals to ensure the optimal performance and longevity of the transmission.

The transmission fluid should be changed every 30,000 miles

The transmission fluid in a 42RLE transmission pan should be changed every 30,000 miles. This is because, over time, transmission fluid will deteriorate and become dirty and clogged with debris, compromising its ability to lubricate and transfer power. Heat is the biggest killer of transmission fluid, and certain driving habits can generate excess heat. These include stop-and-go driving, hauling heavy loads, or towing a trailer. For vehicles operating under "severe service" conditions, it is recommended to change the transmission fluid more frequently.

Additionally, it is important to note that not all transmission fluids are created equal. When it comes to the 42RLE transmission, it is very particular about its fluid. It requires ATF+4, which is a full synthetic fluid specifically designed for Jeep automatics. It is crucial to use only ATF+4 and not a generic or "super" ATF that claims to be compatible.

When changing the transmission fluid in a 42RLE, it is important to consider the type of fluid change. A pan drop and filter change will require around 4 quarts of fluid, while a complete change will require just under 9 quarts. It is also recommended to clean the pan during the service and inspect for any debris or metal shavings that could indicate wear in the transmission.

Furthermore, it is worth considering the use of an external transmission filter. This can make fluid changes easier and less messy, as well as provide additional protection for the transmission by filtering out smaller particles. Some mechanics also recommend adding an auxiliary cooler to help manage the heat generated by the transmission, especially in warmer climates.

In conclusion, maintaining the transmission fluid in a 42RLE transmission is crucial for optimal performance and longevity. By following the recommended service intervals and using the correct fluid, vehicle owners can help ensure their transmission remains in good condition and avoid costly repairs down the line.
