HELP looking for a specific temp sender

yeah I knew that, I think 260* is when the trans goes into hot mode. I wouldnt really use it consistantly, just maybe momentarilly for a few seconds to get a quick idea what oil temp is.
Jon, correct, on the 03+ trucks, all of the sensor signals (save for the speedometer) are sent to the instrument cluster over the class 2 data bus.
01-02 trucks, I think has discrete signal wires (ie, the "old fashioned way instrument panels were wired") for everything except trans fluid temp...fuel level might be over class 2 too, but in general the 01-02 trucks data bus architecture is not half as integrated/steamlined as the post mid-cycle enhancment 2003+ trucks.

I see thanks for the info
there is another way to have a dsp for the TCM
Simon I thought of that, but I think when in "trans hot mode", the TCM changes more things (that are undesirable) than we can change in EFILive.
Ie, yes we can see SOME "trans hot" shift pattern tables, but there are additional converter lockup and pressure/timing tables that we DONT have access to.

I wasnt serious,but what kind of things have you noticed with hot trans?
are they consitant things? could we possibly bennifit from it? if we put in the effort?
I liked the idea,but think a gauge willl be what i go with
Im not sure, I have never had my trans go into "hot" mode. I beleive it changes shift points around and forces the converter to stay locked to try to bring temps down.
I wonder if, when in hot mode, it would force the converter to lock immediately, not like in normal mode where it waits for a specified difference in turbine vs input rpm...hmmmmm.... could be sort of a poor-mans co-pilot.

Jon I thought it was the complete opposite? eSI says it "applies the converter clutch to reduce heat". Where does it say it never locks the converter in hot mode?
If it does we can alter hot mode shifts,fool the sensor into thinking it's hot
and basically use it for a converter lock
Simon hopefully Brayden will see this one, he would know for sur.e
if thats the case then it would definetly be a clever idea!

When my tranny got hot, the converter wouldn't lock. Other than that, I don't know.
An unlocked converter flows way more fluid than an unlocked. FWIW

hmmmm thats wierd...when my buddy's LBZ trans got hot he said the converter wouldnt unlock "Like it was in tow/haul". WIerd??
Minimum calibrated temp. None of the sensors we use go to absolute zero (something less than -200*F) The lower the voltage (resistance) the lower the temp. At 0 Volts (0 Ohms) the sensor is as low as it goes. However, any decent control circuit will pop an error since the sensor would never get there if it was operating correctly.
thanks again fingers
I talked to a few more people Ben and they seem to agree with the unlocked converter To bad,I thought you might be onto something there
