Is the 42RE valve transfer plate a new body?
The 42RE valve body transfer plate is completely new. It is redesigned to accommodate a new governor body and different hydraulic circuitry. The governor pressure solenoid and governor pressure sensor are mounted on this body.
Where to find the part number on a 42RE transmission?
Look for the transmission part/identification number and date code. According to the 42RE service manual on Scribd.com, the codes are located on the driver’s side of the transmission, stamped just above the oil pan gasket surface. The first group is the assembly part number, followed by the manufacturing date.
How are servo valves similar to proportional valves?
Servo valves are a close relative of the proportional valve and are based on an electrical torque motor which produces a small deflection proportional to the electrical current through its coil. They commonly use feedback between the main and pilot spools to give precise control. A typical device is shown in Figure 4.40.
What causes a servo valve to move to the left?
A change in electrical signal moving the pilot spool to the right reduces pressure at the left-hand end of the main spool by bleeding fluid back to the tank. This causes the main spool to move left until, again, pilot sleeve and pilot lands are aligned.

How to identify a sonnax Chrysler 42RLE valve body?
Prior to this, the 604, 606 and 42RLE were fixed line pressure transmissions. The transmission can be identified from the outside by an additional electrical connector sticking out of the case, next to the range sensor connector. It will either be 6 pins or 5 pins. Early connectors had 6 pins, with the #1 pin not being used.
Is the solenoid pack still used with the 42RLE?
The solenoid pack is still used with this valve body, just as it was with the non-variable line pressure units. While Sonnax makes every effort to ensure the accuracy of technical articles at time of publication, we assume no liability for inaccuracies or for information which may become outdated or obsolete over time.
What kind of clutch does a 42RE have?
The 42RE (A500SE) uses electronic components to create governor pressure and the 42RH (A500) uses a mechanical governor to create governor pressure. First through third gear in the 42RE (A500SE) are provided by the clutches, bands, low roller clutch and planetary gear sets located in the transmission main case.
How to find the valve body layout in sonnax?
Look up make and unit, or search all layouts. Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. Each layout:

What kind of transmission does a Chrysler 42RE have?
Updated January, 2003 1 The Chrysler 42RE (A500SE) is a 4 speed automatic transmission. Mechanical and hydraulic components in the 42RE are similar to those found in the 42RH (A500) transmissions. The major difference between them involves the method they use to produce governor pressure for shift control.
What is the valve body on a Jeep Grand Cherokee?
The valve bodies utilize pressurized hydraulic fluid levels for determining which gear set, which is also known as the band servo, to choose when the vehicle changes speeds. And our online store can aid you in choosing the right Jeep Grand Cherokee automatic transmission valve body.

Where can I find the 42RLE transmission number?
The 42RLE transmission can be identified by a barcode label that is affixed to the upper left area of the bellhousing.
How does the ZIP valve body repair kit work?

What kind of transmission system does a 42RLE have?
The 42RLE (Fig. 1) is a four-speed transmission that is a conventional hydraulic/mechanical assembly controlled with adaptive electronic controls and mon- itors. The hydraulic system of the transmission con- sists of the transmission fluid, fluid passages, hydraulic valves, and various line pressure control components.
