that's fair.

in the 04-06, there's two pressure switches, an accessible filter, and the solenoids that can be replaced.

in the 07-08, there's three pressure switches, and no accessible filter. I am not 100% sure, but I think the solenoids are in the same place.

Solenoids are in the same place.

Solenoids... gotta love em. Which ones are recommended to be replaced?

As far as solenoids go (not the 3rd + 4th pressure switches), I believe there are two, along with valve screens located under the airbox for the 04-06 TLs. I have never replaced any of the solenoids or screens, but I'm now interested just for the sake of preventative maintenance. Hopefully somebody with experience can chime in with further info on it. Idk if I should bother cleaning/replacing if I don't really seem to have any issues currently. I did find a good video though (it's not letting me link it for some reason... but the youtube channel is MODS FOREVER and the video title is "how to clean or replace transmission shift solenoid tutorial" where he does it on an 04-06 TL

I just replaced my pressure switches and filter today. Correct me if I'm wrong, but I think the switches I removed are not OEM. Anyways, the car feels great! The filter was gross, but also intact; feels good to replace it.
