The 545RFE transmission is used in a variety of vehicles, including certain models of the Jeep Grand Cherokee, Jeep Wrangler, and Dodge Durango. The oil pan on the 545RFE transmission is secured by 15 bolts, which need to be removed and replaced when servicing the transmission. While the specific bolt size for the 545RFE transmission pan is not readily available, it is important to note that the PML bolts for the Chrysler Dodge 68RFE, 545RFE, and 45RFE deep transmission pans are longer than the OEM bolts to accommodate the thicker flange and gasket.

What You'll Learn
There are 15 pan bolts on a 545RFE transmission
When performing a transmission service, it is important to loosen all the transmission pan bolts. This can be done by jacking up the front of the truck and putting jack stands under the crossmember. It is also important to block the wheels and engage the parking brake. To catch the fluid, place a pan under the transmission and lay a blanket underneath to absorb any spills.
After the fluid has been drained, the magnet should be pulled out of the transmission pan and cleaned. The gasket mating surface on the transmission and the transmission pan should also be cleaned and scraped. Sandpaper can be used to ensure that the surface is completely clean.
Finally, the gasket can be placed into position on the pan, and the bolts can be pushed through the pan and the gasket. The gasket will hold them in place as the pan is raised and threaded into position. It is important not to over-torque the bolts, as this can damage the transmission case or cause leaks.

The 545RFE transmission is used in some Jeep Grand Cherokee models
The 545RFE transmission is an electronically controlled unit that was used in several SUV and truck models from 2001 to 2012. This includes some Jeep Grand Cherokee models, such as the WJ, WK, and WK2, which were manufactured between 1999 and 2012. The 545RFE transmission was also used in the Jeep Commander, another SUV in the Jeep family.
The 545RFE transmission was specifically designed for higher-output Hemi engines, which are known for their powerful performance. This transmission offered six forward speeds and one reserved for kickdowns. It had a tall 3.00:1 first gear for initial acceleration, and the reverse gear was designed to match the first gear to handle heavy loads with ease.
The 545RFE transmission had a broad range of gear ratios within its class, and its computer-controlled system allowed for efficient directing of fluid to the proper clutch pack, ensuring smooth gear engagement. The transmission's capacity is 10.5-11 litres, and it uses Dexron 3-6 or MOPAR +4 fluid.
Over time, the 545RFE transmission was replaced by more advanced options like the 65RFE and 66RFE. However, it played a significant role in improving fuel efficiency and reducing noise in the Jeep Grand Cherokee models that utilised it.
To protect the 545RFE transmission in Jeep Grand Cherokee models, a skid plate can be installed. This skid plate is designed to shield the transmission from rocks, debris, and other off-road hazards, preventing costly damage and providing peace of mind when driving on rugged terrain.

The 545RFE transmission is used in some Dodge models
The 545RFE transmission, formerly known as the 45RFE, was introduced in 1999 and used in the Jeep Grand Cherokee. It is notable for its three planetary gearsets instead of the two commonly used in a four-speed automatic. The 545RFE transmission was used in several SUV and truck models from 2001 to 2012, including the Jeep Commander and Jeep Grand Cherokee with higher-output Hemi engines. It was also used in several Dodge Durango models within this period.
The Dodge Durango is an SUV model that falls under the Dodge brand, which is a division of Chrysler. The 545RFE transmission was also used in other Dodge models such as the Dodge Ram, Dodge Dakota, and Dodge Aspen. The transmission was a good fit for 2-wheel-drive vehicles, as well as all-wheel-drive automobiles. It was even used in Chrysler's entire fleet of rear-wheel-drive trucks, excluding sedans and coupes.
The 545RFE transmission was highly suitable for vehicles with large torque bands, such as the VM 2.8 diesel, Hemi V8, 4.7 V8, and 3.7 V6. It had six forward speeds and one reserved for kickdowns, with a tall 3.00:1 first gear for initial acceleration. The reverse gear was designed to be equal to the first gear to accommodate heavy loads. When it was launched, it had the broadest range of gear ratios within its class.
The 545RFE transmission has been described as pretty strong by some users, while others have experienced problems with the anti-drainback valve in the cooler line. It is important to note that the transmission does not have any transmission bands and relies on a solenoid switch pack to direct fluid to the clutch pack for smooth gear engagement. If the solenoid pack becomes defective, there may be issues with gear engagement and engine stalling.

The 545RFE transmission is used in some Ram models
The 545RFE transmission builds on this by utilising four gears on the upshift and introducing a new "gear", 2nd Prime, with a different ratio to increase versatility when downshifting. Chrysler refers to the 545RFE as a "multi-speed automatic". This transmission is used in some Ram models, including the 1500, 2500, and 3500. It is also found in Jeep models such as the Grand Cherokee WJ, WK, and WK2, as well as the Liberty KJ.
Dodge models that utilise the 545RFE transmission include the Dakota, Durango, and R 1500. It is important to note that not all vehicles with these model names will have the 545RFE transmission, as some offer different transmission options. The 545RFE transmission also has specific bolt requirements for the oil pan, with 15 bolts needed to attach the pan to the transmission.
When considering transmission options, it is important to take into account factors such as the year, make and model of the vehicle, mileage, and warranty coverage. Remanufactured 545RFE transmissions offer a longer warranty period of three years, while rebuilt or used transmissions may have shorter warranty durations. Additionally, the specific variations of the 545RFE transmission differ based on engine size, electronic systems, and solenoids, making it crucial to provide the correct vehicle identification number when ordering a replacement.

The 545RFE transmission is used in some Chrysler models
The 545RFE transmission is a five-speed automatic transmission that was used in select vehicles from Chrysler and Jeep. It was produced from 2003 to 2012 and offered improved performance and efficiency compared to its predecessor, the 47RE transmission. The 545RFE transmission is known for its durability and performance, and it continues to be a popular choice for those who require a capable and efficient transmission for their Chrysler or Jeep vehicle.
The 545RFE transmission was utilized in various Chrysler and Jeep models during the years 2003 to 2012. Some of the car models that utilized the 545RFE transmission within this timeframe include the Chrysler 300, Dodge Dakota, Dodge Durango, Dodge Ram 1500, Jeep Grand Cherokee, and Jeep Commander. It's important to note that transmission availability may vary by specific trim levels, engine options, and production dates within the model years.
The 545RFE transmission features an all-aluminum case and extension housing, hydraulically-controlled planetary gear sets, and electronic shift control. It includes overdrive and lock-up torque converter features, optimizing fuel efficiency and reducing wear on transmission components. The transmission has gear ratios of 2.45:1 (1st), 1.45:1 (2nd), 1.00:1 (3rd), 0.69:1 (4th), and 0.67:1 (5th). It is rated to handle up to 700 lb-ft (949 Nm) of torque, making it suitable for a range of applications.
In terms of design, the 545RFE transmission's hydraulic control system provides the transmission with PARK, REVERSE, NEUTRAL, SECOND, and THIRD gears based on the driver's shift lever selection. This design ensures the vehicle can still be driven ("limp-in" mode) in the event of an electronic control system failure or a situation that the Transmission Control Module (TCM) recognizes as potentially damaging to the transmission. The TCM uses data from various transmission and engine sensors to control transmission shifting, operating the solenoid pack to change hydraulic flow.
