Valve Bodies and Intermediate Band Servo NOTE: If a transmission has been disassembled to replace worn or damaged parts and the valve body sticks repeatedly from foreign material, the torque converter must be removed and cleaned by using a mechanically agitated cleaner, such as Rotunda Torque Converter/Oil Cooler Cleaner 014-00028 or equivalent. Removal If solenoid valve body is going to be replaced: Remove solenoid body connector heat shield and loosen both bolts using an 8mm socket. Remove slotted heat shield. CAUTION: Do not attempt to pry tab with pry bar or screwdriver. Remove the heat shield from the transmission before attempting to remove the connector. Remove solenoid body connector by pushing on the center tab and pulling on the wire harness. Check electrical connectors for terminal condition, corrosion and contamination. Repair or replace as required. 1. Position a drain pan under transmission. 2. Remove all transmission pan bolts except the front ones using a 10mm socket. Loosen only the front bolts at this time. 3. Pry the rear of the pan down and allow the fluid to drain. 4. Remove front pan bolts using a 10mm socket. Remove transmission pan. 5. Remove pump inlet filter and seal assembly by carefully pulling and rotating the filter as necessary. If seal remains in bore, carefully remove using O-Ring Tool T71P-19703-C. NOTE: Discard pump inlet filter and seal. CAUTION: Use care not to scratch or damage aluminum pump bore. 6. Remove 11 accumulator body bolts using an 8mm socket and two nuts using a 10mm socket. Remove accumulator body assembly. NOTE: If separator plate is to be left on the transmission, use one of the reinforcing plate bolts in the hole shown to prevent front of plate from sagging and displacing balls. 7. Remove 14 main control body bolts using an 8mm socket and two nuts using a 10mm socket. Remove main control body. NOTE: Do not remove the two bolts as shown on illustration. This will keep the upper and lower control bodies attached as an assembly. 8. Remove nine solenoid body bolts using a T30 Torx® bit and one nut using a 10mm socket. Push down on solenoid body receptacle to remove solenoid body. 9. Remove solenoid screen by rotating and pulling it out. 10. Remove reinforcing plate bolts using an 8mm socket. Remove plate. 11. Lower separator plate and gasket carefully so that check balls, EPC ball and spring are retained. 12. Remove intermediate accumulator regulator filter and spring assembly. Clean or replace filter as required. 13. Depress retaining plate, remove retaining ring, retaining plate, servo piston and rod assembly and servo spring. Installation

Removal CAUTION: Do not drop hub components during removal and installation. 1. Separate cap from body assembly by removing the three capscrews, using Torx® bit TX25 or equivalent, from the cap. 2. Remove cap. 3. Remove the lock ring seated in the groove of the front disc brake hub and rotor (1102). 4. Remove the body assembly from the front disc brake hub and rotor. Automatic Locking Hub, Disassembled View, Typical 5. Remove C-washer or snap ring from stub shaft groove. 6. Remove spacers (three thrust washers) from shaft. 7. Remove cam assembly. Pull to remove. 8. If front disc brake hub and rotor and front wheel spindle (3105) are to be removed, refer to Wheel Grease Seal and Bearing, Front Replacement and Repacking in the Disassembly and Assembly portion of this section. Installation 1. Align the fixed cam retaining key on the cam assembly (garter spring inboard) with the keyway on the spindle. Firmly press the cam assembly on the wheel retainer nut. 2. CAUTION: Improper sequence of three-piece thrust washers will result in excessive wear of assembly. Install three-piece thrust washer set (first metal, second plastic, third splined) and retainer lock ring on C-clip. It may be necessary to push the axle outboard from backside of knuckle. Be sure retaining ring is seated in groove properly. 3. CAUTION: Rotate moving cam stop (use any one of three) to the one o’clock position in relationship to the fixed cam retaining key. CAUTION: Do not force body assembly into front disc brake hub on rotor if body assembly will not fit. Recheck alignment of all components. NOTE: The hubs should not be packed with grease. Too much grease will damage the hubs and prevent proper operation. Install body assembly into vehicle front disc brake hub and rotor by lining up the three legs outside the hublock body with the three pockets in the cam assembly. 4. Make sure body assembly is in far enough to see groove in rotor tube. Install large lock ring into groove of hub. Be sure lock ring is correctly seated. 5. Install cap to body assembly. Install three capscrews and tighten to 4-6 Nm (35-53 lb-in).

ISSUE Some vehicles built prior to 12/1/2001 may exhibit the following shift and engagement conditions: • No 2nd Gear • No 3rd Gear • No Engine Braking In Manual 1st. Out of specification pressures controlled by the transmission main control valve body separator plate may be the cause. ACTION Verify the condition, the main control valve body separator plate may need to be updated to the latest level. Refer to the following Service Procedure for details. SERVICE PROCEDURE CAUTION TO BE ADDED OR REPLACED FOR THIS TSB. 1. Verify that one or more of the following conditions exist. • Low Line Pressure While In Drive At WOT • No 2nd And/Or No 3rd Gear • No Engine Braking In Manual 1st • DTC P0732, P0733 Or P1762 2. Install Kit (3L5Z-7M203-JA) to update the main control valve body assembly, refer to the installation procedures found in the kit. 3. Reinstall the main control by continuing to follow the installation steps listed in the Workshop Manual, in-vehicle service, main control valve body. 4. After completing the procedure, verify the condition has been corrected.

The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve body assembly. The assembly consists of six solenoids that control hydraulic pressure to the six friction elements (transmission clutches), and the torque converter clutch. The pressure control solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly also contains five pressure switches that feed information to the TCM. OPERATION SOLENOIDS Solenoids are used to control the L/R, 2C, 4C, OD, and UD friction elements. The reverse clutch is controlled by line pressure and the position of the manual valve in the valve body. All the solenoids are contained within the Solenoid and Pressure Switch Assembly. The solenoid and pressure switch assembly contains one additional solenoid, Multi-Select (MS), which serves primarily to provide 2nd and 3rd gear limp-in operation. The solenoids receive electrical power from the Transmission Control Relay through a single wire. The TCM energizes or operates the solenoids individually by grounding the return wire of the solenoid as necessary. When a solenoid is energized, the solenoid valve shifts, and a fluid passage is opened or closed (vented or applied), depending on its default operating state. The result is an apply or release of a frictional element. The MS and UD solenoids are normally applied to allow transmission limp-in in the
