I got the P1739 and P1740 codes a couple days ago, but they cleared and didn't come back.
Car running perfectly. But I've read in the DIY and Fixes sections
that some people replace the pressure switches as a preventative measure,
and that the car shifts a whole lot tighter after replacement.

Does one commonly replace only the 3rd and 4th gear switches?

I t'ink 3rd gear pressure switch is #13, and 4th is #12, in the image below.

And about the others?
What others are there?
Is there one for each gear?
Do most people replace just the two?
Generic comments to check the DIY scetion, or that this has already been covered,
go find someone else's thread to pollute. Thanks!

shall I point you to search~ you know there are pics and help in various threads if not in the real diy section
ck problems and fixes section is my guess for scrolling thru to find

many are simply removing and cleaning the screen w/carb cleaner (?)
others say `lets remove these pita bolts once and install new parts`
it may be budget related too

Gurus of trans servicing,,please advise and show external replacable atf filter too
thank you!! happy holiday~
