Question about 2005 Pontiac Grand Prix

2005 Grand Prix GTP tranny filter

I guess this is more of a question than a problem that needs to be fixed. I have a 2005 Grand Prix GTP Comp G (3.8 L) that has the TAPshift option on the tranny that gives you the option for shifting "manually" as they call it. The car now has 70,000 miles on it and is due for a tranny service. However, I think I read somewhere that b/c the transmission has the TAPshift on it, it comes with a different filter. I have looked all over the Internet, but can't seem to find anywhere that offers anything else besides the standard 3800 tranny filter. Was I just mis-informed and this is a "mythical" filter, or does something like that really exist and I need to track one down?

Any answers would be appreciated.

    Couldn't tell 'ya. It is my daily driver, so I can't just tear it apart and leave it apart while I figure it out. And I looking the the owners manual for info, but couldn't find anything there either...
