Dipstick Tube Seal May Leak Causing ATF Contamination Or Transmission Shudder/Buzz
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.
2005 - 2006 (LX/LE) 300/Magnum/Charger
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.
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
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.
