68Rfe Transmission Line Pressure Sensor Location

The 68RFE transmission line pressure sensor is located on the lower side of the transmission, on the driver’s side. It is a two-wire electrical connector that sends an electrical signal to the powertrain control module (PCM) to indicate line pressure levels in order to monitor and adjust shift points and pressures. The exact location may vary depending on make and model, but it should be accessible from beneath or above after removing some bolts from underneath.

It will also likely have a clip attached for easy removal when servicing or replacing this component.

The 68Rfe transmission line pressure sensor is an essential part of any 68Rfe transmission. It helps to monitor the fluid level and pressure in the system, ensuring that it remains within acceptable parameters for safe operation. The location of this sensor can vary depending on make and model, but typically it is located near or at the filter housing area.

It’s important to periodically check your vehicle’s manual to ensure you know the correct location of this critical component so that you can take timely action if needed.

Where is the Transmission Pressure Sensor Located?

The transmission pressure sensor is usually located on the valve body of the transmission, and it monitors the pressure within the transmission. Its main purpose is to alert you if there’s a problem with your vehicle’s transmission fluid pressure. The location varies depending on make and model, but it should be relatively easy to find as long as you know where to look.

In many cases, it will be located near other sensors in or around the valve body such as speed sensors and shift solenoids. If not, then checking your car’s owner manual can provide some guidance on exactly where it might be found for your particular model of vehicle. It’s important to keep an eye out for any signs that may indicate a bad or failing Transmission Pressure Sensor since this could lead to damage further down the line if left unchecked.

Therefore having knowledge of its exact location can help ensure that you catch any issues early enough before they become something more serious!

What Should Line Pressure Be on a 68Rfe?

When it comes to the line pressure on a 68RFE, there is no one-size-fits all answer. The correct line pressure for your specific application will depend on several factors such as engine components and any modifications you may have made. Generally speaking, the ideal line pressure for a stock 68RFE transmission should be around 150 psi during light throttle applications, and up to 175 psi under heavy load conditions.

However, if you’ve made any changes or additions that could affect how much power your engine produces—such as installing an upgraded turbocharger or tuning software—you should aim for higher pressures. Keep in mind that running too low of line pressure can lead to premature wear in the clutch packs, while running too high can cause excessive heat build-up within the transmission system which can further damage internal parts over time. It’s always best practice to consult with a professional before making any adjustments to ensure your setup is optimized properly.

What Causes Low Line Pressure in a Transmission?

Low line pressure in a transmission is caused by a number of different factors. The most common factor is the age and wear on the components within the unit, such as seals, clutches, bands and valves which can all begin to deteriorate over time leading to decreased performance. Other problems that could be causing low line pressure are worn or damaged solenoids, vacuum leaks, blockages in the hydraulic control circuits or worn-out pump internals.

Poor engine operation can also lead to lower than normal line pressures due to inadequate fluid flow from lack of power or improper valve timing resulting in insufficient volume being delivered through the system. Even leaking coolers and lines can produce excessive heat inside your transmission which causes fluids to boil off leaving it with less lubrication and thus result in reduced line pressures as well. Finally, if your vehicle has recently been serviced or rebuilt it’s possible that incorrect parts have been used during assembly resulting in poor performance when you try using them on an older model car.

How Do I Fix Code P0871?

If you are having trouble with your vehicle and the code P0871 appears, there is no need to panic. This code indicates that there is a problem in your transmission fluid pressure sensor circuit, which may be causing it to malfunction. To fix this issue, it’s important to first locate the Transmission Fluid Pressure Sensor (TFPS).

It is typically located on the side of the transmission near where the shift linkage connects. Once you have found this component, disconnect its electrical connector and inspect it for any signs of corrosion or damage. If present, clean or replace as necessary before reconnecting and testing again.

Additionally, check all wiring harnesses connected to the TFPS for breaks or corrosion as well as look for loose connections at both ends of all related wiring connectors. Finally verify that power and ground circuits are providing correct voltage levels when tested with a multimeter set to DC Volts mode. Following these steps should help resolve code P0871 and get your vehicle running optimally again!

68Rfe Line Pressure Sensor Failure

The 68RFE line pressure sensor failure is a common issue for Dodge Ram owners, resulting in symptoms such as transmission slips, jerks and hard shifts. This can be caused by an electrical issue with the line pressure sensor or its wiring harness, leading to inaccurate readings and improper shifting of gears. If left unchecked, this could lead to further damage to your transmission system and ultimately result in costly repairs.

It’s important that you have any signs of a 68RFE line pressure sensor failure checked out immediately by a qualified mechanic – doing so will help keep your vehicle running smoothly and safely!

68Rfe Governor Pressure Sensor Symptoms

The 68RFE Governor Pressure Sensor is an important part of the transmission system, and when it malfunctions, there are a few symptoms that drivers may notice. These include poor fuel economy, hard shifting or delayed shifts between gears, surging engine speed without corresponding changes in vehicle speed, and even illuminated dashboard lights warning of trouble with the transmission. If these issues occur, take your car to a qualified mechanic as soon as possible to have the sensor checked.

68Rfe Pressure Switch

The 68RFE Pressure Switch is an important component of the transmission system in a Dodge Ram truck. It regulates the pressure within the transmission, which helps to maintain optimum shifting performance and prevent damage to other components. The switch also helps protect against fluid leaks by monitoring fluid levels and alerting drivers if there’s too much or too little pressure present.

When functioning correctly, this switch can help keep your vehicle running smoothly for many years down the road.


In conclusion, the location of the 68RFE transmission line pressure sensor is an important factor to consider when working on or replacing a transmission. It can be found in the valve body and should be replaced if it fails. Knowing where this component is located can save time, money and frustration for any mechanic or automotive technician that deals with transmissions.
