The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Record by record

13 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

Symptom

Component named as the cause

Work done

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Known issues4L60-E / 4L65-E clunk on 2-3 upshift or 3-2 downshift (normal condition)1

  1. Manufacturer communication2005–2006 GMC YUKON XL ・ 2018-05-21

    2-3 Upshift and 3-2 Downshift Clunk Normal Condition

    1. 1Fault

      • A clunk noise can be heard on a 2-3 upshift or a 3-2 downshift.
      • The condition may be more pronounced on a 4-wheel drive vehicle because of the additional tolerances in the transfer case.

    2. 2Finding the cause

      Possible causes

      • During a 2-3 upshift the 2-4 band is released and the 3-4 clutch is applied; the timing of this shift can momentarily reverse the torque on the output shaft, which makes the clunk.
      • The same torque reversal can occur on a 3-2 downshift, when the 3-4 clutch is released and the 2-4 band applied.

    3. 3Correction

      Caution

      • For 2005 model year fullsize utilities and pickups, refer to Corporate Bulletin Number 05-07-30-012.
      • This is a normal condition; no repairs should be attempted.

    From the manufacturer’s document

    • Applies to：Applies to 2014 and prior GM passenger cars and light duty trucks with the 4L60-E, 4L65-E or 4L70-E automatic transmission (RPOs M30, M32, M70).
    • Caution：For 2005 model year fullsize utilities and pickups, refer to Corporate Bulletin Number 05-07-30-012.
    • Condition：A clunk noise can be heard on a 2-3 upshift or a 3-2 downshift.
    • Cause：During a 2-3 upshift the 2-4 band is released and the 3-4 clutch is applied; the timing of this shift can momentarily reverse the torque on the output shaft, which makes the clunk.
    • Cause：The same torque reversal can occur on a 3-2 downshift, when the 3-4 clutch is released and the 2-4 band applied.

    Open the manufacturer’s document (PDF) ↗ The points above were read from this document.

    Remedy
    This information was created to inform the technician that the 2-3 upshift and the 3-2 downshift clunk is caused by the releasing of the 2-4 band and application of the 3-4 clutch assembly during an upshift. Also during a 3-2 downshift, the releasing of the 3-4 clutch during the application of the 2-4 band, can cause torque reversal down the output shaft creating a clunk. This is a normal condition.

      Confirm

      • Test the 3rd accumulator checkball capsule for leakage; a leaking capsule is a leading cause of 3-4 clutch failure.

      Repair

      • Thicker heavy-duty backing plates that eliminate clutch pack flex are available in the aftermarket.

      Caution

      • An obvious leak such as a cracked apply piston should not stop further investigation.

Known issues4L60-E slip or no forward engagement right after input housing replacement (service part 17803687)1

  1. Manufacturer communication2000–2006 GMC YUKON XL ・ 2017-08-15

    Input Housing Inspection for Forward Range Slip

    1. 1Fault

      • A few transmissions may slip or have no engagement in any forward gear immediately after the Input Housing (621) is replaced.

    2. 2Finding the cause

      Possible causes

      • The Input Housing (621) from GM Service Parts may have an incorrectly drilled input shaft.

      Steps to confirm (in the document’s order)

      1. With the Input Housing (621) completely assembled, apply regulated compressed air to the 3-4 clutch feed hole and the forward clutch feed hole one at a time.
      2. Air should not leak out of the 3-4 clutch feed hole when air is applied to the forward clutch feed hole, and not out of the forward clutch feed hole when air is applied to the 3-4 clutch feed hole.

    3. 3Correction

      Repair

      • If air leaks between the two feed holes, replace the Input Housing (621) with one from GM Service Parts, ordering new housing part number 19125752.

    Automatic Transmission Oil Cooler Flow Test Essential Tool J-45096

    1. 1Fault

      • In flow mode, an electronic flow meter measures the flow capability of the ATF oil cooling system.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. On the 4L60-E, the cooler feed (exiting the transmission) is the bottom connector and the return (entering the transmission) is the top connector; J-35944-200 may be required.
      2. On the 4L80-E, the cooler feed is the front connector and the return is the rear connector; J-35944-200 may be required.

    3. 3Correction

      Repair

      • For the flow test and flush procedure, refer to Automatic Transmission Oil Cooler Flushing and Flow Test J-45096 in SI.

      Caution

      • Insufficient oil flow through the ATF oil cooling system will cause premature transmission failure; the required minimum flow rate depends directly on the supply oil temperature.
      • The oil in the supply vessel must be 18°C (65°F) or warmer for the J-45096 to operate.
      • Labor operations that remove the transmission for an internal repair or torque converter replacement include time to flow check and flush the transmission oil cooler system.
      • A flow test and flush uses between 4.7-7.5 L (5-8 qts) of DEXRON VI transmission fluid.
