One more shouldve taken a pic question - transmission temp sensor

Folks, once again kick myself in the heine for not taking pics.....3 ports on the auto transmission. from YOUTUBE i discern that the 1st port nearest the bellhousing area is for the temp sensor and the other two are the cooler lines?

Is that correct? THNX!

It isn't 100% clear from the pictures I have, but that's what it looks like. The lines remaining in the truck should line up with things, so it will 'correct' you when you get there.

A quick a340f image search popped this up. Matches what is on my trans when I did my new lines.

The hottest point in the transmission is the nearest cooling line to the bell housing and the sensor like [MENTION=405460]2TH4IST[/MENTION] image shows.. There is where one would plumb in aux sensors if needed. 2nd option would be on that front line.
Pre 1999 do not have a Temp sensor nor the ecu circuitry to do more then when the sensor hits a certain temperature turn on the idiot light.
 
THNX FOLKS! I did not want to assume, and indeed Charlie the old trans lines ( which i need to have redone) do line up with the two more rearward holes,.

THNX 2TH for the pic.

The sensor is still there with the same specs as the '99+ transmissions - the ECU just doesn't report it out via OBD-II. It still uses temperature information to control shifting operations internally, and light the idiot light, as you point out.

Do you happen to know if the sensors are the same from 96 -02? As I am looking into putting another sensor in down the road for temp readings in the older 96 to 98 3rd gens.. I wish there is a way to easily pull that sensor data or parallel into it so one can just put a temperature gauge in. I am thinking they are not and why I have to plumb something else in in that area. 99+ you can just read the data out on an obd II software or like I hope to do with an andriod radio, just run it all the time on the radio screen. Most of my fleet though are 97 and 98.. Hence why I am curious..:-)

PN 89429-35042 (trans temp sensor) is the same part used on ALL 4Runner and Tacoma A340s from '88 to '04, along with T100 and Tundra V6.
