This kit contains the following 45RFE/545RFE transmission components:
Kit P/N 68002342AB (1999-2003) contains the following 45FRE/454RFEtransmission components:
1 Solenoid assembly 52119435AB1 TRS cam plate assembly 04799654AC
Kit P/N 05170877AC (2004-2006) contains the following 45RFE/545RFEtransmission components
1 Solenoid assembly 52119435AB
A “quiet” (NVH) solenoid assembly was released for 2004 MY (and later) RFEtransmissions. This new solenoid requires a revised TRS cam plate assembly,which includes a deeper “trough” for TRS pin clearance in the Reverse PRNDLposition. The “deep trough” cam plate assembly (04799654AC) has also been inproduction since 2004 MY.
A new version of the NVH solenoid (52119435AB) may now be used to serviceprior model (1999-2003) transmissions, ONLY if the “deep trough” cam plateassembly is installed along with the solenoid.
Using the new NVH solenoid (52119435AB) with the original (1999-2003) camplate assembly may result in improper (intermittent or no) backup light function.Using the previous NVH solenoid (52119435AA) in 1999-2003 MY transmissions,EVEN WITH the new cam plate assembly, may cause invalid DTCs, limp-in, etc.and is not allowed. The “deep trough” cam plate assembly may be used with anystyle solenoid in any MY.
This kit contains the new NVH solenoid and the “deep trough” cam plateassembly. When servicing 1999-2003 MY transmissions, install BOTHcomponents from this kit as a set. The solenoid in this kit may be usedindividually ONLY in 2004 MY and later transmissions. Both parts in this kit arealso available as a separate service parts for use in 2004 MY and later units.

A missing #4 CK Ball will cause the oil in the O/D Circuit to leak into the switchvalve circuit (following page).
Off the manual valve, oil feed that is normally blocked by the #4 check ball feedsinto the O/D circuit. This oil ends up between the switch valve pucks forcingthem to separate and move the solenoid switch valve into the TCC position. Thiscauses the L/R sol signal oil to feed the Converter Clutch Regulator Valve causingthe TCC to apply.

RE Series AllGovernor Diagnosis
Finally, a complete guide to the RE Series electronic Governor diagnosis.
Although the system seem complex, it truly is not. With a brief understanding ofeach of the circuits as inputs we can understand how the computer responds incontrolling the regulation of Governor pressure. The system hydraulically is basi-cally the same as the RH (mechanical governor) when it controls movement of theshift valves. Line oil feeds the governor solenoid and is converted into governorpressure as the module regulates flow through voltage control.

Pressure testing the Governor: Chrysler uses a series of 6 tests to check thehydraulic circuits in the transmission. The governor test is 5 in the order. Whentesting, remember that governor pressure is used to move shift valves, (electroni-cally controlled) = road speed (diesel higher than road speed after 20 mph). Mustbe less than 5 psi standing still!
Test 5Checks governor operation by measuring governor pressure response to changein wheel speed (signaled by the OSS). It is usually not necessary to check gover-nor operation unless shift speeds are incorrect or if the transmission will notdownshift.
Drive vehicle on the road (important, make sure that the hose will not hit againstanything as the vehicle is being driven.)Idle in drive - Less than 3 psi.
Slowly increase vheicle speed. Pressure should rise in proportion of vehicle speed.Diesel applications will increase in a higher increment above 20 mph (almostdoubling wheel speed).

Vehicle speed must be greater than 25 mph before the transmission will up shiftto overdrive. Sensor is a Hall effect device. Sensor pulses 8,000 times per mile.Used for lock up and 4th gear, as well as a back-up signal for the OSS.
Sensor input is 2.5 volts DC10 mph—16Hz20 mph—36Hz30 mph—46Hz40 mph—56Hz
Starting in 1998 the Vehicle Speed Signal was moved from a direct input to ashared input. The signal from the VSS now goes directly to the ABS Module be-fore being shared via the Network with the other modules.

The TP Sensor determines what the load (driver demand) on the engine is. Sensorhas a 5 Volt reference, 0 volt ground, and a varying voltage signal sent back to thecontroller.
Gas:1 volt or less at idle 4.50 at full throttle
Diesel:1 volt or less at idle 3.50 volts at full throttle
Diesel 1998-on: TPS signal originates from the engine module (mounted on theside of the engine block) known as APPS voltage. From the engine module thissignal is mirrored and sent out as TPS voltage to the powertrain module.

RPM sensor is a typical Hall-Effect sensor that sends a pulse signal to the modulein reference to engine RPM is. The sensor can be located in a wide range of areasfrom the front of engine such as a Diesel which is mounted in the side of theengine block reading a pulse wheel mounted onto the crank shaft. Signal voltageis similar to Vehicle Speed signal.

RE Series AllTemperature Sensors (ECT & TFT)
These sensors are variable resistance sensors. As fluid temperatures increase anddecreases a signal voltage wire advises the module as to what the temperature is.Early sensors had a decrease in resistance as temperature increased and startingin 2000 on the transmission sensor it was opposite. Resistance increases as tem-perature increases. Very important DO NOT mix these sensors up. Earlier yearsthese signals helped to determine when the transmission could go into TCC andOD. With the RE units these signals are still important for TCC and OD but alsofor governor control (part of the governor curve strategies). The TOT sensor origi-nally was riveted to the solenoid block (1993 1/2). Because of ease in manufac-turing and sharing the ground circuit with the transducer, the sensor was movedinto the governor sensor.

RE Series AllPark Neutral Switch
This is a safety switch that allows the vehicle to be started in Park and Neutral.Other responsibilities of the switch are to supply a signal voltage to the reverselights and also to inform the module when the shifter has been moved from parkor neutral into drive range. In Park and Neutral signal voltage in low (grounded)in Reverse and Drive ranges the signal voltage is high (battery voltage) allowingthe computer to recognize forward movement and governor control. If the moduledoes not get a correct signal from this switch, governor control is prevented aswell as shifts into OD and TCC.

RE Series AllTransmission Range Sensor
The Transmission Range sensor has 6 pins in which only 5 are used. Pins twoand five are used to signal the computer for each of the shifter positions. This newswitch works off of resistors to drop or raise voltage supply to the module inform-ing these actual positions.

RE Series AllQuick Reference Signal Voltages for
Governor ControlNote: When doing electrical testing, save yourself valuable time. Always discon-nect and clean battery terminals before doing any electrical testing.
At that time confirm that battery surface voltage is at least 12.45 volts (70% capac-ity of battery ability). Any ground locations, make sure that there is no voltage inthe ground wires (redundant visible grounds).
For testing, it is important to know that volt meter leads will be moved for testing.All controller tests with the exception of two (2) of the tests will be done with thenegative lead of the DVOM on the negative battery post and the module will beback probed with the positive lead.
The governor solenoid test will be done with the positive (+) lead of the DVOM onthe positive battery post and the module will be back probed with the negativelead to determine the working voltage on the governor solenoid. The output speedsensor (AC generator) will need both the DVOM leads on the two (2) computerwires recieving a signal from this sensor. Important, this is AC voltage.
Keep alive battery voltage should not be below 12.45 volts. Running voltages needto be no more than 14.6 volts (generally around 13.2). Computer grounds musthave no more than 0.02 volts. Sensor grounds can be a little higher than systemgrounds about 0.04. The Switches change state when a button is pushed (ODCancel). Normally there is voltage at the computer pin for the switch, and whenswitch is pushed (grounded) voltage will be pulled low and then will return tosystem voltage when released.
TCC and OD Solenoids Both the TCC and OD Solenoids will have battery voltagepresent up to the point that the module supplies the ground to energize thesolenoid. At this point, voltage will be pulled low as the solenoid is turned ON.

CLUTCH APPLICATION CHARTELEMENTS APPLIED
In total, the 62TE provides seven forward ratios and one reverse.
The underdrive compounder assembly has two modes of operation: Direct andReduction.
The 2-3, 3-2, and 4-2 shifts require a “double swap” shift. This occurs when twoelements are turned off while two different elements are engaged.
The clutch-to-clutch synchronization takes place within 40 – 70 milliseconds,producing a smooth shift. If the underdrive compounder assembly shifts too early(in relation to the shifts taking place in the main centerline), a shudder or harshshift results. If the underdrive assembly shifts to late, the driver experiences a“double bump” sensation.
To avoid a double swap shift in a 6-4 downshift, the transaxle shifts into 4th prime,which requires the deactivation of the OD clutch and the simultaneousapplication of the UD clutch.

The 62TE transaxle has eight solenoids. Six solenoids use ON/OFF or PWM op-eration and are part of the solenoid/pressure switch assembly. The TCC solenoidhas a VFS design and is mounted on the solenoid/pressure switch assembly. ThePCS mounts on the valve body and is a separate component.
In the event of a transmission/transaxle electrical fault, a “limp-in” mode proce-dure is programmed in the transmission controller. To achieve “limp-in” mode,the normally applied 2/4 and UD solenoids only allow fluid flow to obtain Park,Reverse, Neutral and Third in Drive.
