I subscribe to the Alldata service, which is a computer database of info of all sorts on cars. American Honda has restricted Alldata from getting TSB's, etc for a number of years. However, here is a list of known TSB's, dealer adjustments, etc, for the 1996 TL:

Note the familiar topics: paint, wind noise, transmissions seal installation, etc.

Here is a Honda perf FAQ summary that is primarily for the 4-cyl engines, but touches on many other questions as well. Cannot say I agree with the assessments in all cases, but it is pretty comprehensive:

Hope this is a bit useful.
