One of the best ways to increase the line pressure of a 68RFE transmission is by increasing the spring pressure on the Pressure Control Solenoid (PCS). This can be done with an aftermarket valve body, or by replacing the stock PCS with one that has greater spring tension. Additionally, installing a larger bore Transmission Control Solenoid (TCS) can also help increase line pressure.
Finally, installing a higher quality filter and/or upgrading to synthetic fluid will ensure that all parts are running at optimal performance levels and provide additional protection against wear and tear.
How to Raise Chrysler RFE Transmission Line Pressure — No Tuning Required
- Check Shift Solenoid Resistance: First, use a multimeter to check the resistance of the shift solenoids
- Generally, an acceptable range is between 11-13 ohms for all three solenoids
- If any of them are outside this range, they will need to be replaced before you can increase line pressure
- Replace Filter and Fluid: Next, replace your transmission filter and fluid with high quality products designed specifically for 68RFE transmissions
- This new fluid will help ensure that your transmission has adequate lubrication while increasing line pressure levels in the process
- Adjust Pressure Regulator Spring: After replacing the filter and fluid, adjust the pressure regulator spring on your valve body to raise line pressures across all gears by 5-10 PSI from stock settings
- You may need a special tool to make these adjustments properly depending on what type of valve body you have installed in your vehicle’s transmission system 4 Install New Governor Pressure Sensor: Finally , install a new governor pressure sensor if necessary as it helps regulate increases in line pressures more accurately than its stock counterpart does
68Rfe Transmission Line Pressure Sensor Location
The 68Rfe transmission line pressure sensor is located near the transmission pan, just underneath the vehicle. The purpose of this sensor is to measure the hydraulic pressure inside the transmission in order to adjust shift points and shift timing accordingly. This information helps ensure that your engine runs more efficiently and effectively while also extending its lifespan.

What Controls Line Pressure in a 68Rfe?
Line pressure in a 68RFE is controlled by the transmission control module (TCM). The TCM monitors data from various sensors and then adjusts line pressure accordingly. During normal driving conditions, the 68RFE operates at line pressures ranging between 40-200 psi, depending on vehicle speed and load.
These pressures can be monitored through an aftermarket scan tool and adjusted if needed with a tuner or other aftermarket parts. Additionally, the 68RFe has a series of solenoids that are used to regulate oil flow inside the valve body which also affects line pressure. Ultimately, proper functioning of these components is essential to ensure that your transmission performs reliably over time while providing smooth shifts as well as optimal fuel economy.
How Do You Increase Transmission Line Pressure?
Increasing transmission line pressure is an important part of maintaining a reliable and safe energy system. Pressure in the transmission lines affects the flow of electricity, so it’s essential to ensure that these pressures remain within acceptable limits. Several methods can be used to increase pressure in transmission lines, including adjusting valves on gas or steam turbines, increasing turbine power output by adding more fuel or expanding existing fuel sources, and changing electric generator parameters.
The most common way of increasing pressure is by installing a pump into the main line that increases the water level upstream from where it enters the pipeline. This raises both temperature and pressure inside the pipe which results in increased pressure downstream as well. Additionally, some modern systems employ sensors to detect changes in static head (the difference between two points along a fluid column) which can help regulate pressures even further when coupled with automated valve adjustments.
Using any combination of these strategies will help you maintain sufficient levels of pressure within your transmission line network for optimal performance and safety at all times.
Where is the Line Pressure Sensor on a 68Rfe?
The line pressure sensor on a 68RFE transmission is typically located between the valve body and the solenoid assembly. It is usually positioned near one of the external ports for fluid flow, though it can also be found at different locations depending on your specific model. The line pressure sensor measures the amount of hydraulic pressure that’s being supplied to various components within the transmission system.
This helps determine when certain parts need to shift gears or adjust other settings as needed in order to maintain optimal performance. By monitoring these readings, technicians are better able to diagnose any potential issues before they become major problems requiring extensive repairs or replacements.
What Causes Low Line Pressure in a Transmission?
Low line pressure in a transmission can be caused by several factors. The most common cause is a worn-out fluid filter, which restricts the flow of transmission fluid and reduces the pressure within the system. A clogged or restricted valve body may also reduce line pressure as it constricts the flow from various solenoids that control shift timing, torque converter lockup, and other functions.
Worn valves, springs, spools, and check balls can create restrictions in hydraulic circuits that prevent proper operation of clutches and bands resulting in reduced line pressures. Damaged seals or gaskets can allow fluids to leak out of hydraulic circuits reducing overall system pressure needed for effective shifting operations. Lastly, low quality lubricants or contaminated fluids may lead to poor shifting performance due to excessive wear on internal components leading to inadequate line pressures necessary for smooth shifts under load conditions.
Conclusion
Increasing 68Rfe line pressure is a great way to improve your vehicle’s performance and extend the life of your transmission. This blog post has provided important information on how to increase the line pressure, including what tools are needed and step-by-step instructions. With this guide you can easily raise the line pressure yourself without having to take it into a shop or pay for expensive services.
Hopefully this article has been helpful in giving you an understanding of how to make these changes safely and effectively so that you can enjoy improved performance from your vehicle for years to come!
