TSB Question

[The Unabomber]

In regards to TSB#: 21-011-05 which you can look at here: http://www.wkjeeps.com/tsb/tsb_wk_2101105a.pdf


What was it that was causing the issue in the first place? Was it a bad seal, was it an inproperly installed seal? Anyone have any idea? Also I'm curious as to how exactly to determine if I need to be concerned about this TSB or not. I'm guessing first thing to do is make sure the seal is properly installed as described in the TSB. What does the shutter they are talking about feel like? How should I look/feel for it? Certain MPH etc? I hear the biggest issue is due to the condensation from the AC dripping right there around the filler tube. Thanks for any/all info.


Edit -

This tsb was replaced with the following tsb http://www.wkjeeps.com/misc/LX/TSB/TSB_2100306.pdf


It states this in the TSB:

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.


So since I have a build date of 4-05 does that mean I'm most likely not going to be affected? It was built before Dec. 05, but I doubt the transmission has a build date from July. Any thoughts?

NAG1 transmissions built prior to July 08, 2005 may have suspect fill tube seals, your transmission falls within the affected date so you'll need to have the tranny checked.

So after reading the revised TSB it looks like they are replacing the seal regardless of there being an issue. I'm wondering if I should get this done or just let it be. Appears they where having a huge issue with the old seals. This new one that they replace it with isn't even requireing the use of RTV anymore. Hmm. Decisions, decisions. Wonder if I should have them do it.
