The following new service information outlined in this bulletin will aid technicians in providing easy to follow valve body reconditioning instructions and new illustrations to simplify reassembly of the valve body. The service bulletin will also provide additional service information documents that are related to the 4L6x transmission family.

Important: If valve body cleaning is not required, Do Not disassembly bores unless it is necessary to verify movement of valves.

Inspection Procedure

  1. Using the exploded views in this bulletin, inspect each bore for freedom of valve(s) movement and evidence of debris. Pay particular attention to those valves related to the customer's concern.
  2. Verify movement of the valves in their normal installed position. Valves may become restricted during removal or installation. This is normal due to small tolerances between the valves and bores.
  3. If a valve is restricted and cannot be corrected by cleaning valve and bore, then replace valve body. Describe restricted valve on repair order.

Notice: Be sure all solenoids are installed with the electrical connectors facing the non-machined (cast) side of the valve body; otherwise, the solenoids will bind against the transmission case as the valve body bolts are tightened and damage may occur.

Disassembly/Reassembly

  1. If a valve is restricted by a metal burr from machining that bore, remove valve and burr, then inspect movement in the valve's normal position. If no other debris or restrictions are found, then reassemble valve body and install in the transmission.
  2. If the valve body has been contaminated with debris from another transmission component failure, then disassemble all bores for complete cleaning of all valve body components. If possible keep individual bore parts separated for ease of reassembly. Use the following illustrations in this bulletin for a positive identification and location of individual parts:
    Left Side Control Valve Body Assembly
    Right Side Control Valve Body Assembly
    Control Valve Body Assembly Chart, Valve Springs and Bore Plugs
  3. Using GM Brake Clean, or equivalent, in a safe and clean environment (clean aluminum pan) clean the valve body and dry it with compressed air. Use appropriate eye protection.
  4. Clean individual valve body components with GM Brake Clean, or equivalent. Coat each valve with clean ATF and reassemble in each bore. Check each valve for free movement during assembly of each bore.

    This PI has been revised to update include 2006 Model Years and different models. Please discard PIP3253A.


    The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

    Condition/Concern:

    Vehicle will not move in either direction. Transmission may show over full. Converter may be empty of fluid. The TCC Control Valve #334 may be stuck in bore. If the valve is stuck in the right position, the converter may not circulate fluid causing no movement.

    Recommendation/Instructions:

    1. Duplicate the concern with line pressure gauge installed to insure proper line pressure at start up.
    2. Check for any current or history DTCs.
    3. Check for proper fluid level.
    4. Check for the TCC control valve item #334 for being stuck in the right hand position. If the valve is stuck, the valve body should be replaced.

    Some teardowns have identified oil pump rings broken in no/low pressure situations. The PSM or Transmission Fluid Pressure Switch (03-07-30-021) and Driven Sprocket Support Sleeve turned (03-07-30-012) have also been the cause of some "No drive, No reverse" concerns.

    2004 model year valve bodies have updated #334 valve that is a larger diameter than the previous one.

    Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

    This bulletin is being revised to include additional diagnostic information and clarify model usage. Please discard Corporate Bulletin Number 02-07-30-013D (Section 07 -- Transmission/Transaxle).


    Condition

    Some owners may comment on any one or more of the following conditions:

    The SES lamp is illuminated.
    The transmission slips.
    The transmission does not shift correctly, is very difficult to get the vehicle to start moving or the engine lacks the power to move the vehicle.
    Poor engine performance.

    Cause

    The most likely cause of the various conditions may be chips or debris:

    All years--Pressure Reg. Valve (Bore 1) or Torque Signal Valve (Bore 4) stuck.
    On 2001-2002 vehicles, a plugged orifice on the case side of the spacer plate.
    ON 2003-2005 vehicles, restricted movement of the 2-3 shift valves in the valve body.
    On 2003-2005 vehicles, restricted movement of the 3-4 shift valves in the valve body.

    Technician Diagnosis and Correction

    The technician's road test reveals the vehicle launches in third or fourth gear (high RPM with slow vehicle acceleration).
    On 2001-2002 vehicles, a DTC P0756 or P0757 may be stored.
    On 2003-2005 vehicles, a DTC P0730, P0741, P0748 or P0757 may be stored.
    Refer to the appropriate Service Information (SI) for additional Diagnostic Assistance.
    With a Tech 2® connected to the vehicle, road test the vehicle and perform the following steps:

    If the above symptoms are present proceed with the following steps.

    1. With the valve body removed and on a workbench, carefully push the valve against spring pressure to check if the valve will snap back to the original position. Or for the valves seated in home position, use a small flat-bladed screwdriver and carefully pry the valve off its seat, quickly remove the screwdriver allowing the valve to return to its seat. If the valve does not snap back unencumbered, then the valve will need to be removed from the valve body.
    2. Once the valve is removed, inspect for any scratching or scoring.
    3. If any scratching or scoring is found, then the fingernail test will need to be performed.

      Important: It has been found that in most cases that the scratches are not severe enough to catch your fingernail.

    4. Using your fingernail, move over any scratches to see if your nail will catch on the scratch or score.
      If your nail catches in the scratches, the valve will need to be replaced.
      If your nail does not catch in the scratches, continue with the next step.

      Important: Clean the valve body with the machined side down so debris may escape.

    5. Clean the valve and bore using brake cleaner.
    6. Blow off with shop air.
    7. To verify free movement of the valve, dip the valve into clean ATF and install the valve back into the appropriate bore. The valve should move freely. If the valve moves freely, in most cases the valve body will function properly when reinstalled.
    8. Reassemble and retest .

    Subject:SES Lamp Illuminated, DTC P0741 - TCC Stuck Off (Reprogram the PCM)

    Models:2002 Chevrolet Malibu
    with 3.1L Engine (VIN J -- RPO LG8) and 4T40-E Transaxle
    Built between SOP and VIN Breakpoint 2M665370

     

     


    Condition

    Some customers may comment that the Service Engine Soon lamp is illuminated. The torque converter clutch is no longer operational. The engine speed seems to be higher than normal when driving at highway speeds.

    Diagnostic Tip

    The technicians may find DTC P0741 stored, (TCC stuck off).

    Correction

    Reprogram the PCM with the new service calibration available from Techline in March, 2002 on the TIS 2000 version 22.003 or newer.
