What is a line pressure solenoid?
The line pressure solenoid is a variable force-type solenoid and is an integral part of the solenoid pack. The TCM controls the variable force solenoid by increasing or decreasing the duty cycle to obtain the pressure necessary. When duty cycle is at its lowest range (5% or solenoid off) pressure rises to maximum.
Where is the transmission pressure sensor located?
The Transmission Fluid Pressure Sensor/Switch (TFPS) is usually found attached to the side of the valve body inside the transmission, although sometimes it may be found screwed into the side of the transmission case/body itself.
Is the 545RFE a good transmission?
The 68RFE is just a 545RFE with upgraded internals and slightly lower gear ratios. They are great transmissions when properly maintained and get even better with a bit of tuning.
What does a governor pressure solenoid do?
The computer uses the governor pressure solenoid to generate governor pressure relative to road speed, emulating what the hydraulic governor did in older ‘RH’ series transmissions. The computer varies the duty cycle to the PWM governor pressure solenoid to achieve the desired output pressure.
How do I know if my transmission pressure switch is bad?
Top Signs of a Failing Transmission Position Sensor
- Car fails to move out of park. When your vehicle is unable to shift out of neutral or park, this is a clear indication that there is a serious problem somewhere in the transition system.
- Transmission shifts into the wrong gear.
- Vehicle becomes locked in a single gear.
What is the difference between 45RFE and 545RFE?
The 45RFE and 545RFE are identical mechanically. The difference is in the software. Before you drop the transmission, though, pull the trans oil pan off and look at the valve body. On the passenger side of the main valve body is a cover plate that covers the accumulator pistons.
How much HP can a 545RFE handle?
Stock Hemi LX’s usually do 180-200 hp at the wheels (same engine components), but they have a better exhaust, which helps. Yes, a longer stroke means more torque, but usually won’t rev. as well. Torque is what you need more of to haul the heavy WK around.

What are the electronic components of a 45 / 545RFE transmission?
The electronic components of the 45/545RFE transmission consist of various sensors and switches as input information to the TCM, that the TCM uses to determine the appropriate gear ratio and shift schedule points.
