Understanding the 68RFE Transmission
The 68RFE transmission is a crucial component in many Chrysler vehicles, playing a vital role in ensuring smooth and efficient power delivery. Let’s delve into its design, functionality, and the various Chrysler models in which it is utilized.
The 68RFE transmission is a six-speed automatic transmission designed by Chrysler specifically for heavy-duty applications. Its primary purpose is to transfer power from the engine to the wheels, allowing the vehicle to move forward or backward. This transmission is commonly found in trucks, such as the Ram 2500 and 3500 models.
One notable feature of the 68RFE transmission is its robust design and construction. It is built to handle the demands of towing and hauling heavy loads, making it a reliable choice for drivers who require exceptional performance from their vehicles.
In terms of functionality, the 68RFE transmission operates based on a hydraulic system that relies on fluid pressure to engage and disengage the gears. It utilizes a torque converter, which acts as a fluid coupling between the engine and the transmission, allowing for smooth power transfer and efficient gear changes.
Chrysler has integrated the 68RFE transmission into various models, including the Ram 2500 and 3500 trucks, as well as the Dodge Ram 4500 and 5500 chassis cabs. These vehicles are commonly used in commercial settings, where durability and towing capacity are of utmost importance.
Common Problems Faced by the 68RFE Transmission
When it comes to the 68RFE transmission, there are a few common issues that Chrysler owners have reported. Let’s explore these prevalent problems and understand their impact on the performance of the transmission.
| Problem # | Issue | Explanation |
| 1 | The Torque Converter | Issues with the torque converter can cause transmission slipping, shuddering, or failure. |
| 2 | The High-Pressure Oil Pump | A malfunctioning oil pump can result in inadequate hydraulic pressure, leading to gear-shifting problems. |
| 3 | The Input Shaft | Worn-out or damaged input shaft can cause difficulties in shifting gears or loss of power transmission. |
| 4 | The Input Clutch Drum | Problems with the input clutch drum can lead to gear slipping, grinding noises, or difficulty shifting into gears. |
| 5 | The Center Support | Center support issues can cause excessive vibrations, gear slippage, or even complete transmission failure. |
| 6 | The Low/Reverse Drum | A damaged low/reverse drum can result in gear slipping, grinding noises, or difficulty shifting into low or reverse gears. |
| 7 | The Oil Pan | Leaking or damaged oil pan can lead to fluid loss, inadequate lubrication, and transmission overheating or failure. |
| 8 | The Flexplate | Cracked or misaligned flexplate can cause rattling noises, engine misfires, or prevent proper transmission engagement. |
Problem #1: The Torque Converter
The torque converter is a critical component of the 68RFE transmission. However, it is susceptible to problems that can affect the overall performance of the transmission. Issues with the torque converter can lead to symptoms like transmission slipping, delayed engagement, or shuddering during gear shifts.
Problem #2: The High-Pressure Oil Pump
The high-pressure oil pump is responsible for supplying hydraulic pressure to the transmission. If this component fails or malfunctions, it can lead to a loss of pressure, resulting in erratic shifting, harsh engagement, or even complete transmission failure.
Problem #3: The Input Shaft
The input shaft connects the engine to the transmission and transfers power between them. Over time, this shaft can wear out or become damaged, leading to issues such as difficulty shifting gears, strange noises, or even a complete loss of power transmission.
Problem #4: The Input Clutch Drum
The input clutch drum is responsible for engaging and disengaging the gears in the transmission. When this component experiences problems, it can lead to gear slippage, erratic shifting, or even a complete loss of power.
Problem #5: The Center Support
The center support is an essential component that provides stability and support to the transmission. However, it is prone to wear and tear over time. If the center support fails, it can lead to excessive vibrations, gear slippage, or even a complete transmission failure.
Problem #6: The Low/Reverse Drum
The low/reverse drum is responsible for engaging the low and reverse gears in the transmission. Over time, this drum can develop cracks or other forms of damage. When this happens, it can result in issues like gear slipping, grinding noises, or difficulty shifting into low or reverse gears.
Problem #7: The Oil Pan
The oil pan holds the transmission fluid, which is essential for lubrication and cooling. However, the oil pan can be prone to leaks or damage due to road debris or accidents. A damaged oil pan can lead to fluid loss, inadequate lubrication, and ultimately, transmission overheating or failure.
Problem #8: The Flexplate
The flexplate connects the engine to the torque converter. It is subjected to high levels of stress and can develop cracks or become misaligned. A damaged flexplate can cause symptoms like rattling noises, engine misfires, or even prevent the transmission from engaging properly.
