1st PrintingApril, 2011INTRODUCTION46RE, 47RE, 48RE,The 46RE, 47RE and 48RE family of transmissions by the Chrysler Group, are fitted behind a wide variety ofengine sizes, including diesel, and across various vehicle lines. They are also available in 2WD and 4WDconfigurations. Beginning at the start of production for model year 2005, Dodge trucks equipped with the 5.9Ldiesel and 48RE transmission were equipped with an electronically controlled Transmission Throttle ValveActuator (TTVA). This Actuator has replaced the previous Throttle Valve Cable and all associated linkage.A push-in Transmission Range Sensor was implemented in model year 2002 to replace the screw-in Park/Neutralswitch.The 46RE, 47RE and 48RE transmissions are all four speed fully automatic units with an electronic governor.They are equipped with a lock-up clutch in the torque converter. First through third gear ranges are provided by theclutches, bands, low-roller clutch, and planetary gearsets in the transmission. Fourth gear is provided by theoverdrive unit (rear section) that contains an overdrive clutch, OD/direct clutch, overrun roller clutch, and planetarygearset.These units contain a front (direct) clutch, rear (forward) clutch, and OD/direct clutch which serve as the inputdriving components. They also contain a kickdown (front) band, low/reverse (rear) band, overrun clutch, and theoverdrive clutch which serve as the holding components.We wish to thank Chrysler Group for the information that has made this booklet possible.No part of any ATSG publication may be reproduced, stored in any retrieval system or transmitted in any form orby any means, including but not limited to electronic, mechanical, photocopying, recording or otherwise,without written permission of Automatic Transmission Service Group.

Technical Service InformationGENERAL DESCRIPTIONThe 46RE, 47RE and 48RE family of transmissions bythe Chrysler Group are fitted behind a wide variety ofengine sizes and across various vehicle lines, as shownin Figure 1. They are also available in 2WD and 4WDconfigurations, as shown in Figure 2. Notice also inFigure 2, at the start of production for model year 2005,Dodge trucks equipped with the 5.9L diesel and 48REtransmission, were equipped with an electronicallycontrolled Transmission Throttle Valve Actuator(TTVA). This Actuator has replaced the previousThrottle Valve Cable and all associated linkage. Thepush-in Range Sensor was implemented in model year2002.The 46RE, 47RE and 48RE transmissions are all fourspeed fully automatic units with an electronic governor.They are equipped with a lock-up clutch in the torqueconverter. First through third gear ranges are providedby the clutches, bands, low-roller clutch, and planetarygearsets in the transmission. Fourth gear is provided bythe overdrive unit (rear section) that contains anoverdrive clutch, OD/direct clutch, overrun rollerclutch, and planetary gearset. Refer to Figure 3 for theinternal component locations and identification.These units contain a front clutch, rear clutch, andOD/direct clutch which serve as the input drivingcomponents. They also contain a kickdown (front)band, low/reverse (rear) band, overrun clutch, and theoverdrive clutch which all serve as the holdingcomponents.VEHICLEDODGE, VAN/WAGONGRAND CHEROKEEDODGE, DAKOTADODGE, DURANGODODGE, RAM PICK-UPDODGE, RAM PICK-UPDODGE, RAM PICK-UPDODGE, RAM PICK-UPDODGE, RAM PICK-UPThe driving and holding components combine to selectthe necessary planetary gear components in the front,rear, or overdrive planetary gearset and transfer theengine power from the input shaft through to the outputshaft. Refer to Figure 4 for the component applicationchart for which component is applied for each gear.First, second and third gear shifts are controlled by anelectronic governor solenoid, that is mounted on thevalve body assembly. The shift into fourth gear andtorque converter clutch are controlled by individualseperate solenoids that are also mounted on the valvebody assembly.The valve body is mounted on the lower side of thetransmission and contains the valves necessary forpressure regulation, fluid flow control and clutch orband application. The valve body assembly hasreceived several upgrades and changes over the years.The oil pump is mounted at the front of thetransmission and is driven by the torque converter hub.The oil pump supplies the pressure necessary for clutchand/or band application and transmission lubrication.VEHICLE APPLICATION 5-021995-022003-072003-075.2L (V8)4.7L (V8)5.9L, (V8)5.9L, (V8)5.2L, 5.9L, (V8)5.9L, (Diesel)8.0L (V10)5.9L (Diesel)8.0L (V10)COUNTRYTRANSMISSIONCAN, MEX,USA,USA,USA,USA, MEX,USA, MEX,USA, MEX,USA, MEX,USA, MEX,46RE46RE46RE46RE46RE47RE47RE48RE48RECopyright 2011 ATSGFigure 1AUTOMATIC TRANSMISSION SERVICE GROUP3

The OSS monitorsrotating speed of the output shaft.The OSS is triggered by the external park lugs on therear planetary ring gear to determine the exacttransmission output shaft speed. The OSS signal, andother inputs, are used by the TCM/PCM/ECM todetermine the required governor pressure for currentconditions. This has a direct effect on which gear ischosen for the vehicle. The controller also uses thisinformation to schedule torque converter lock-up.Should the OSS fail, the speed signal from the ABScontrol module is used as a back-up, and code P0720will be stored in TCM/PCM/ECM memory.The OSS sensor and wire schematic for Gas and Dieselis shown in Figure 6.PCM 1996-03ECM 2004-UP(GAS & DIESEL)(DIESEL)13 OUTPUT SHAFT SPEED SENSOR (ALL MODELS).14 OUTPUT SPEED SENSOR "O" RING SEAL.Copyright 2011 ATSGFigure 6AUTOMATIC TRANSMISSION SERVICE GROUP7

Technical Service Information6SIEMENS VDOEXTERNAL ELECTRONIC COMPONENTS (CONT'D)Transmission Throttle Valve Acuator (TTVA)Beginning at the start of production for the 2005 modelyear, all Dodge trucks equipped with the 5.9L dieselengine and the 48RE transmission, received anelectronically controlled Transmission Throttle ValveActuator (TTVA), as shown in Figure 7, for improvedshift control. The TTVA is mechanically connected tothe throttle valve in the valve body by the "D" shapedopening in the bottom of the TTVA shaft and retainedwith two mounting bolts, as shown in Figure 7. Thisrequired two added bosses to the transmission case.The TTVA has replaced the previous Throttle ValveCable and all associated mechanical linkage, on dieselmodels only.The TTVA consists of an electronic DC motor, twopotentiometers and a gear driven system that controlsall functions of the throttle valve in the valve body.
