Speaking of the 7AT I installed a trans cooler yesterday (ill be doing a DIY) but in the mean time does anyone know where to purchase the fitting for the tranny pan so I can add fluid at home insted of having to go to the dealer?

You don't need a "fitting" really, you just need a small-diameter plastic tube (they have rolls of it at hardware stores, buy a few sizes), to stick into the fill hole, and a way to adapt that small-diameter tube to your fluid pump (e.g. using some slightly-larger silicone hose that fits over it snugly or whatever).

The the thing that forces most to the dealer is the temperature issue, because only the dealer can read the official internal temperature of the TCM. Be sure to read up in the service manual about it. You can approximate it with an IR thermo though, details here:

nice! this may be my next mod. can definitely feel when the tranny is being pushed too hard.

what kit did you buy or did you piece together one?

think you're supposed to add the ATF to the radiator core prior to install to avoid having to go to the dealer.

If you pre-fill the new cooler (and the lines, with them pointed up in the air - 4 hands helps a lot!) and then swap all the connections around quickly, the level will be "close enough" to drive around for a while and not worry too much. However, even on the street (at least in Texas weather) that fluid looks/smells horrible after ~20K miles, so it's a good excuse to go swap all the fluid shortly afterwards anyways (either at the dealer, or DIY).

GTM has a chart at the bottom of their fluid swap PDF about fluid temps vs change intervals: http://www.gtmotorsports.com/Manuals..._Procedure.pdf . I haven't (yet!) had live trans temps to look at, but I'd guess in hot weather even street cars are bumping into that 215 range, and track cars probably go quite a bit higher without add-on cooling.
