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

17 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.

How it is said to have ended

  • says it held for a while1
  • says it did not fix it1
  • result not stated8

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.
    • Condition：The condition may be more pronounced on a 4-wheel drive vehicle because of the additional tolerances in the transfer case.
    • Caution：This is a normal condition; no repairs should be attempted.

    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.

Known issues4L80-E / 4L85-E planetary gear whine in first and second gear1

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

    Planetary Gear Whine Noise in First and Second Gear

    1. 1Fault

      • The 4L80E/4L85E automatic transmission may have a planetary gear whine noise in first and second gear, typically louder in first gear than in second.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. If the noise is judged abnormal and the transmission was built after 9-01-03, perform the Rear Unit End Play Check (SI Document ID # 52027).
      2. The correct end play is between 0.127-0.508 mm (0.005-0.020 in).

    3. 3Correction

      Repair

      1. If end play is out of specification, inspect and replace the output planetary gear set (661 - Output Carrier Assembly and 650 - Sun Gear) as necessary.
      2. Set the rear end play with the correct selective thrust washer (674), targeting between .010 and .015 in.
      3. If end play is within specification, replace the transmission assembly, referring to bulletin 02-07-30-029A before ordering it.

      Caution

      • This planetary gear whine can be characteristic of the 4L80E/4L85E; compare the vehicle with an identically built vehicle (same GVWR) before attempting any repairs.
    Read the sentences of the record

    From the manufacturer’s document

    • Applies to：Applies to 1999-2007 GMC Sierra and Yukon XL (among other listed GM trucks and vans) with the 4L80E (RPO MT1) or 4L85E (RPO MN8) transmission (note: the Yukon XL range runs to 2007).
    • Condition：The 4L80E/4L85E automatic transmission may have a planetary gear whine noise in first and second gear, typically louder in first gear than in second.
    • Caution：This planetary gear whine can be characteristic of the 4L80E/4L85E; compare the vehicle with an identically built vehicle (same GVWR) before attempting any repairs.
    • Confirm：If the noise is judged abnormal and the transmission was built after 9-01-03, perform the Rear Unit End Play Check (SI Document ID # 52027).
    • Confirm：The correct end play is between 0.127-0.508 mm (0.005-0.020 in).
    • Repair：If end play is out of specification, inspect and replace the output planetary gear set (661 - Output Carrier Assembly and 650 - Sun Gear) as necessary.
    • Repair：Set the rear end play with the correct selective thrust washer (674), targeting between .010 and .015 in.
    • Repair：If end play is within specification, replace the transmission assembly, referring to bulletin 02-07-30-029A before ordering it.

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

    Remedy
    This Preliminary Information communication provides information to the technician about vehicles that may have a planetary gear whine noise in first and second gear. Technician should compare the noise to a like vehicle. Technician will need to check the build date of the transmission, if it was built after 09/01/2003 and it is determined that a vehicle has an abnormal amount of noise, perform the rear unit end play check. Technician will replace the output planetary gear set if end play is out of specification. The transmission assembly will need to be replaced if the end play is with in specification.

Known issuesSingle-cylinder misfire (P0300-P0308) and/or chirp, squeak or tick at camshaft speed: worn cam lobe / lifter, valve or valve spring1

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

    Service Engine Soon Lamp, Misfire, and Engine Noise Information

    1. 1Fault

      • With the SES light on, a P0300-P0308 DTC is found with misfires counting on a single cylinder that may or may not be felt.
      • A verified noise is not eliminated by canceling fuel injectors and occurs at camshaft speed (half of crankshaft speed); it may be a chirp, squeak, squeal or tick and may increase off idle.

    2. 2Finding the cause

      Possible causes

      • When SI diagnosis does not isolate the cause, it may be a worn camshaft lobe and/or lifter roller, a sticking valve, valve leakage, a broken valve spring, or a collapsed AFM (Active Fuel Management) lifter.

      Steps to confirm (in the document’s order)

      1. During the noise, press with a wooden hammer handle on the valve side, push rod side and side of each rocker arm; if pressure on the valve side changes the noise, it is most likely a lifter and/or cam lobe concern on that cylinder.
      2. Measure cam lobe lift at the push rod side of the rocker arm and compare with other rockers on the same bank; the misfiring or ticking cylinder should have clearly less lift if a lifter roller and/or cam lobe is worn.
      3. A good indicator of a sticking valve is misfires that continue to count on an aggressive deceleration with engine braking.
      4. For a suspected sticking valve, snap the valve onto its seat and confirm it comes off easily; if force is needed to tap it off the seat, excessive carbon build up exists, which may be repaired by decarboning the engine.
      5. The Cylinder Leakage Test outlined in SI should isolate valve leakage by finding excessive leakage past an intake or exhaust valve compared with the others.

    3. 3Correction

      Repair

      • If a worn camshaft lobe or lifter roller is found, replace the camshaft and all lifters per SI, and also replace the plastic lifter guide for the lifter that had the damage.

      Caution

      • A worn cam lobe is easy to overlook through the lifter bores, and unworn lifter rollers do not mean the related cam lobes are okay; both must be carefully inspected.
