All CTD's have it.... even the manual trannys!
It's in all gauge clusters, but disconnected if not an automatic.
Actually that's the light. You asked about the sensor, which I assume is also included in all 50 prong CTD wiring harnesses. Would make sense since, when mfg. engines, they don't know which engine will go with which tranny.

Mine is in the hot line, regular cruising with ambient air temps ~85°F, I will see trans temp between 155-160°. Highest temp I've seen is 195° in stop and go traffic.

As said before, you should pull over when the temp hits 210°. Pull over, shift to NEUTRAL, and idle the engine 1200-1500 RPMs to circulate more tranny fluid through the coolers. If you pull over at 210° and cool off, you can safely continue to use the current fluid in your tranny. 225° is the danger temp, if you haven't pulled over by now, you really should. The protective qualities of the fluid start to degrade around this point. 250°+ and you are now scorching the fluid, and some tranny internals begin to wear out at an abnormal pace, namely the clutch packs. Fluid will smell burnt, and will need to be replaced soon after, as the fluid has lost much of its protective and lubricating properties.

 

I cant fine the factory sensor on my truck which is why I was asking.

 

On '96 and newer the factory sender is internal to the tranny.

 

That would be a good reason I cant see it.

 

The tranny temp light will come on about ten minutes after the tranny is toast!! Get a gauge and use it , especially when backing a load for any time at all! I had to install a deraile fan on the front of the existing cooler up front on a dash switch for backing loads. With no air flow it gets hot in a big hurry!

 

Normal city driving I see between 160-180*. Cruising down the highway my needle just sits on 140*. I really need to get a lower reading gauge.

 

does anybody have the steering coloum mount on a 94-97 truck with pic and does it cover up much of the dash?

 

I've had my guage pegged at 280+ for 10-15 minutes, and the stock tranny warning light never came on.

My sensor is in the hot line, no idea where the stock sensor is.

Fluid smelled, as my son put it, like burnt toast.

I have my fuel pressure gauge there on my 02. let me know if you want a pic. I'll snap one real quick.

I does cover some of the idiot lights but not much of the speedomiter. Hang on I'll go take a pick so you can see what I'm talking about.

 

Here they are

This is a view behind the gauge, kinda blurry but you get the picture



Here is what I see, the gauge looks bigger and blocks more of the cluster in the picture than in reality, camera is closer to the gauge than my head.

 

thankyou thats what I was looking for.

 

The owners manual says the O/D OFF light comes on at 270*, and if temp goes up from there, the TRANS TEMP light will come on.

So, I agree with the above.
