where can i find the AT sensor? I checked multiple web sites from the forum but no luck, i also checked the forums part section and still no luck on a part number.

MD609333. Here's a link to download CAPS . Pretty useful.

thanks DirtDriver!

well I spoke to my mechanic about replacing the A/T temp sensor. He told me the sensor cost about $45 to $100 bucks and that it is located within the transmission which will be expensive to replace due to the labor involved to get to it. I got the impression from the replies that the sensor was located on the outside of the transmission which made it somewhat easier to get too.

He's wrong. It's on the outside of the tranny, passenger side. Tee'd into the fitting that the line to the cooler hooks up to. It's tight, but doable, especially if you let him have it long enough to have a good cold catalytic converter. He just doesn't want to do something that hard that's that cheap. Go ask the mitsu dealership if they have a flat rate time for the job. Bet it's 1/2 hour or less...

You can see it's limited access. I think you'll need a crows foot, but with a hoist it should be fairly easy.

Thanks everyone for the help. I ordered the A/T temp switch from the dealer $45, and they will charge $95 to install it so see if he will install it for less.

I'm no mechanic and I did mine in about 15 minutes. If you have five digits and can hold a wrench you can do it yourself. Then you're only out the $45 for the part.

Rapha, thanks for the post. I had the dealer change it for me. I took a look at where it was located on the tranny, took into account that I haven't had any time during the week or weekends to do this myself. I know! I should have made the time, because it cost me $95 bucks for the dealer mechanice to replace in about 10 mintues. It took longer for the service tech to right up the paperwork. Oh well, at the least its done, no more AT temp light coming on, and I am also glad to report that the "fasten seat belt" light is now remaining off as well. Its sporadic, but no remaining on all the time.
