Date: February 18, 2006
Models: 2005-2006 LX (300/Charger/Magnum)
NOTE: This bulletin applies to LX/LE vehicles equipped with a NAG1 transmission (sales code DGJ) that were built prior to December 2005 with a TRANSMISSION build date of July 08, 2005.
Subject: Dipstick Tube Seal May Leak Causing ATF Contamination Or Transmission Shudder/Buzz
Overview: This bulletin involves tests to be performed on the transmission to determine the integrity of the transmission oil fill tube seal. Dependent upon test results: the oil tube seal will require replacement, the transmission may require a flush procedure, and/or the transmission torque converter may require replacement.
Symptom/Condition: Water may leak past the transmission oil fill tube (dipstick tube) seal. Dependent upon the amount of water accumulation in the transmission oil, the customer may experience a transmission shudder vibration and/or an audible high frequency buzz-like sound. The shudder vibration or buzz-like sound may be most noticeable during light acceleration where partial application of the torque converter clutch (TCC) in 3rd, 4th, or 5th gear occurs.
The shudder/buzz condition may be due to the torque converter clutch and a “stick-slip” condition caused by contaminated transmission oil/fluid. The transmission fluid contamination may be caused by water intrusion past the transmission fill tube seal.
