Product Update: PCM Update for Lock-Up Clutch Function
(Supersedes 09-037, dated July 15, 2011, to revise the information marked by asterisks)
REVISION SUMMARY
*Under WARRANTY CLAIM IN FORMATION, the flat rate time was changed.*
BACKGROUND
A judder from the torque converter lock-up clutch may be felt while driving between 20-45 mph. To minimize the opportunity for the judder to occur, a software update for the transmission is available.
If judder occurs sometime in the future, after the PCM A/T software is updated, the torque converter may need to be replaced.
CLIENT NOTIFICATION
NOTE:
For the December 14, 2009 version of this service bulletin, only 2,100 notifications were sent to clients in four southeastern states as part of a limited campaign. Vehicles repaired according to the December 14, 2009 version of this service bulletin still need the latest PCM A/T software installed.
All owners of potentially affected vehicles will be sent a notification of this product update.
Not all vehicles within the affected VIN range have lock-up clutch judder. To verify vehicle eligibility, check for at least one of these items:
^ The client has a notification letter.
^ The vehicle is shown as eligible on a VIN status inquiry.
In addition, check for a punch mark above the third character of the engine compartment VIN. A punch mark in that location means this product update has already been completed.
Some of the vehicles affected by this product update may be in your used vehicle inventory. These vehicles must be updated before they are sold. To see if a vehicle is affected by this campaign, do a VIN status inquiry before selling it or returning it to a service client.
Should an unrepaired vehicle that was in inventory, or that came in for service after this service bulletin was issued, cause an injury or property damage because of the campaigned item, the dealership will be solely responsible to the damaged party, and will be required to defend and indemnify American Honda for any resulting claims.
CORRECTIVE ACTION
Update the PCM A/T software.
