Anyone have any info on the 4L60E transmission temperature probe? I did a T56 swap into my '01 Silverado and would like to get a cluster with the trans temp gauge built in and put the probe into the T56. Or, is there an aftermarket probe that will work like an Autometer sending unit?

 

put the sending unit in place of the drain plug, I think it's 1/2" NPT, should come with the adapters you need

 

Are you talking about the factory 4L60E probe? Is it threaded?

I'm not sure if an Autometer (or other) probe would work with a stock cluster.

 

no aftermarket, I'm not sure what a factory trans temp sender looks like. Autometer sending can be had in multiple temp ranges, might find one the same as factory

 

Temperature range doesn't mean a whole lot. The probe resistance needs to be correct to be compatible with the gauge in the stock cluster.

 

they're sold in temp ranges, i.e. 100-240 F, 100-260 F etc... I would imagine if a factory gauge reads 100-260F then an Autometer sending unit 100-260F would work. Right ?

 

But the gauge interprets resistance from the sending unit I think (the resistance varies with temperature), so the aftermarket sending unit must have the same resistance properties as the stock probe or else it won't work with the the stock gauge.

I emailed Autometer to see if they have anything that would work.

 

Response from Autometer:

All of our gauges are made specifically for our sensors and due to our products all being universal, they are not compatible with any OEM/factory sending unit, just like our sending units would not properly operate a factory gauge/computer input. Our gauge must use our sending unit in order to function properly. In almost every case I've found, the range and resolution that our sending units operate in is far beyond any OEM/factory sensor I've found specs for. They are much different scaling and are not compatible.

Long story short, I probably have to use a factory probe in order to use the factory gauge. Anyone know where to buy a factory probe?

 

I'll be damned
