I have a 2002 tacoma and had an autometer gauge installed. The tech said he conected it to the overtemp sensor? I got the truck home and get a trouble code p0710 that is a sending unit malfunction. Also, the temp has not gone above 100F and the tech said that the gauges barely move. Doesn't seem right?
Can you connect the gauge to the overtemp sensor?
I'm going to bring the truck back in, but I want to educate myself.
what kinda temps ya getting not towing? or towing in Texas?
It verys... freeway driving alittle over 100 degrees, around town close to 180 degrees. This is without towing and with a TRD tranny cooler after the stock cooler. When i moved here at the start of summer towing about 4000 lbs with the tow package climbing mountain grades sometimes in second gear it got as high as 220.
This also taking temps before the coolers.

I have been looking at the Cyberdyne setups and might give them a shout to see if they can fit my Tundra with anything, they have some nice digital gauges and 2 or 3 group clusters. Idiot light and computers just do not do it for me. I was waiting till Scanguage did something with the tranny temp but they will not even answer my email so looking elsewhere! 220 is kinda high for ATF fluid i would check it really close for being burnt, color or smell!!
I don't think the overtemp sensor was correct at all, if it even exists on the Tacoma. There should be a temp sensor that you could tap and that should be the right one.

The most accurate location for the sending unit is in the tranny pan. I bought a 2nd pan and had the sending unit mounted inside, then swapped the old for the new. I have an Auto Meter 'A' pillar tranny temp gauge wired to it.
For the Tundra owners reading this thread, normal summertime (stop and go commute driving) non-towing temps on my Tundra are about 180 degrees. I'm running a larger aftermarket cooler with Amsoil in the tranny. I also installed a thermostatically controlled fan that kicks on at 180 degrees. This also helps to move the air when I'm wheelin on the trails and the speed is too low for good cooling air flow.
Towing our 26' Outback travel trailer (5,600 lbs) on the flats at 60 mph in the summer shows about 165-180. Going up a good long grade I've seen 225. I believe on the 1st gen Tundra's the warning light comes on @ 270. Regardless, I've never had the light come on. I now have over 125,000 on the clock and no problems! I love my Tundra!
