What does the 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 you replace a pressure control solenoid?
How to Replace a Pressure Control Solenoid Valve in a…
- Disconnect the battery. Remove the negative terminal with a socket set and wrench first, then remove the positive cable.
- Pull the oil pan from the bottom of the transmission.
- Unthread the bolts or screws on the fix plate and remove it.
Where is the pressure solenoid located?
They are usually located within the valve body, the transmission control module, or the transmission control unit. In most cases, solenoids are installed inside of the oil pan, connected to the valve body of the transmission.
What does a transducer do in a 47RE transmission?
The solenoid rapidly energizes and de-energizes to create governor pressure, while the transducer sends feedback to the powertrain control module (PCM) on governor fluid pressure and fluid temperature.
What happens when governor pressure overcomes line pressure?
When throttle pressure overcomes governor pressure, the transmission downshifts. When a driver accelerates to pass another vehicle, there’s an increase in throttle pressure, causing a downshift.
Can I put a 48RE replace a 47RE?
Premium Member. You can pretty much swap all the internals of the 47 to a 48 with little issue.
What may cause hard shifting?
Causes of rough shifting include: Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions.
How is the governor pressure solenoid packed in the kit?
The governor pressure solenoid contained in this kit is packed in fluid from the factory. This is the only way to ensure they are functioning upon installation, with no sticking valves.
What are the problems with a BorgWarner governor pressure solenoid?
The heavy-duty BorgWarner governor pressure solenoid included in this kit is a huge upgrade over OEM. The added 3-4 accumulator spring in this kit is also a major upgrade. These transmissions commonly had broken springs, which can cause 3-4 shift problems, or even transmission failure. Typical problem: Wrong gear start.
What does a BorgWarner transmission solenoid Kit do?
This kit will restore your transmission electronic function to better than factory level. The heavy-duty BorgWarner governor pressure solenoid included in this kit is a huge upgrade over OEM. The added 3-4 accumulator spring in this kit is also a major upgrade.
What years do shift control solenoids come in?
The shift control solenoids and sensors contained within this kit can all be installed with the transmission in the vehicle during a routine fluid change This full electronics set will work in the following years: 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, and 2008
