well i do agree on the stock water gague being an idiot light, i was more talking about moving the sender to the hottest place in the water path. In any event a temp gauge is better than no gauge.

It is a pretty good investment and reads about 20 other parameters.

Did a search and here are some direct quotes from the Pro's:

I've always been taught that the sensor needs to be mounted in the return cooler line or in the oil pan. In these locations you will get a much more accurate reading of oil temp. The reason is because the temp of the oil is fairly close to over all trans temp. Cooler oil is lube oil pressure/flow and this is what is used to cool and lube the parts. The temp of that oil is much closer to accual trans temp. I hope this makes sense. I do know that main line pressure tap is the easy way to go but IMO not correct.

Putting the Tap into the cooler line gives you the true temp right out of the converter, which in my humble opinon is the temp you wanna monitor. However there are those who choose to install the tap into the lube circuit (upper or return oil), this gives you the temp of the lube (cooled) oil. Putting them in the pan just makes a mess/however is a better place than the pressure port....but still not as true as the cooler/ lube return lines...hope this helps Dave

Very easily read at night, since it is an LED backlit gauge.

This is all the info/pictures I have. It's been a while since I did this, so I don't remember the size or anything, I just took the sending unit to Lowe's and matched it with a brass T-fitting. One side is bigger because the factory rubber line is smaller than the 3/8" line supplied with the cooler. The rest is pretty self-explanatory. Just have to remember to run the proper ground wires. The instructions are a little vague that come with the temp gauge. Hope this helps.

As said somewhere above, the pcm reads from a stupid place, it takes the pcm a while to read the temp changes,, i.e heat it up by stalling up and the temp rises some 30 secs later. using the aeroforce gauge.
