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.
MODELS:
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.
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.
DIAGNOSIS:
1.
Determine if the original transmission fill tube seal has been previously replaced with fill tube seal p/n 05189087AA (or later).
2.
Has the transmission oil fill tube seal been replaced with p/n 05189087AA (or later)?
a.
If YES >> STOP. This bulletin does not apply. Further diagnosis is required.
b.
If NO >> Proceed to the next step.
