So I bought a basic transmission temperature gauge so I could hopefully encourage myself to baby the tranny. The sensor that came with the setup is a simple threaded sensor, but i can't find where to put it, if anywhere (any ideas or pics?). Is the attached pic the tranny temp sensor? Can I tap into the OEM sensor wiring instead of using the supplied sensor w/the gauge? I do not have a cooler.

 

That the speed sensor.. temp sensor is by the thermostat housing, but nothing relate to transmission temp..

 

Is there anyway to get even an approximate temp of the tranny? Or does everyone with a tranny temp gauge also have a cooler

 

If you insist with the install, then you probably need to mod one on your tranny line that connect the the cooler, connector on the line that would fit your threaded fitting, so like a 'T' connector which then link up to your gauge. Maybe someone else have better suggestion.

I personally don't have any temp gauge for the tranny fluid.

 

Its not going to help you baby the trans. Trans fluid temp IS NOT the problem with these trans. You would have to get a way to monitor the temp of the 3rd gear clutchpacks to accurately monitor and baby the trans.

 

I know that a hot transmission is a result, not the cause of our failures, but I have a warranty for my rebuilt transmission that is valid as long as a certain temp isn't exceeded by the fluid. Knowing if my tranny is really hot (not necessarily exact temp) can help know if something is screwed up before my fluid gets scorched. Still wondering if I can tap into the OEM sensor wire for a ballpark reading, just can't figure out how to get to it...

 

I think it's doubtful that the values would be compatible. Try taking it to the trans shop that did the work and have them tap into the trans or make an adapter in your cooler loop. Someone recently posted an article on here from trans digest or from sonnax about excessive heat in gear at idle in these transmissions. It migh be nice to know. Realistically,though, like fsttyms said, it probably won't help.

 

If you're really worried, just do the 1x3 drain & fill of the tranny fluid more frequently.

 

Thanks, I'll talk to my mechanic and keep up with the tranny flushes

 

Im going to have to say that what ever shop you had rebuild it gave you a nice line BS about warranty only being valid if the trans fluid hasnt reached a certain temp and if the trans does fail again they are just going to use that line as reason NOT to cover it.

Like i said, a trans temp sensor isnt going to help you know. The trans temps will rise and lower normally due to shifting. The Fluid itself in the trans is NOT getting to hot and is NOT the cause of the failures. The LACK of fluid to 3rd gear is the issue causing the 3rd gear clutchpacks to overheat and wear quickly.

And the factory trans temp senor is located towards the bottom of the trans on the drivers side end. If you turn the wheel all the way and look thru the drivers side wheel well you will see it.

 

Yeah, even if I did realize there was a problem, I guess I'd had to tow my car all the way to the garage, which is a couple hours away... Another failure happening at 250K, i'll be ready to let go.. I'll just keep up with those drain and fill's.
