Transmission to ecu cable

Is there a plug in type of cable from transmission to either ecu or wiring harness? I feel the transmission temp sender is not connected to proper place. My scan gauge shows nothing for tranny temp. Thanks to all

 

You can try manually inputing these codes for you auto transmission temps with scan guage

Trans Temp (auto only)
TXD: 686AF101B4
RXF: 044105B40000
RXD: 2808
MTH: 00090005FFD8

 

Do these codes work for you? What year is your taco? Sorry my profile shows 04 taco and mine is actually 2000. There in lies the problem. Need someone to chime in that has 2000 taco and scangauge 2

 

I'm 85% positive that these are the codes I used on my 2003 DC auto transmission. I also added a cooler and my temps never run above 190 even in the summer.

 

I contacted scangauge tech support and they walked me thru every step in the setup. When we got to final step, TFT showed on my scangauge 2, but no value beside it. Just blank. His opinion is that 2000 model would not work with scangauge. No one can say exactly when this feature would work. My 2004 prerunner worked fine with same scangauge.

 

My 99 prerunner trans temp shows on obd fusion. Never tried scanguage. Some say 99 was first year available thru obd.
