What is the operating temp for a Automatic transmission for the C5?

Patches

There is a temp sensor in the tranny that monitors temp and sends a warning if it exceeds a certain level:

"High Trans Temp"
This message is displayed when the PCM detects a transmission fluid temperature (TFT) equal to or greater than 130°C (266°F) for 5 seconds.

The tranny can work in any normal environment where this temp is not exceeded, although, keeping the temp considerably lower will dramatically extend its life. I added an aftermarket tranny cooler when I swapped in 3.42 gears and a high-stall torque converter.



Here are the temp sensor specs

Sorry to dredge up such an old thread, but I have been scouring web searches and every manual I could get my hands on for days to get a chart like this.

I am converting my T56 Caprice to a 2002 Z06 PCM. The wiring harness has the wires and the PCM pinout shows the sensor, but buying a new one and the associated connector is going to chew through some serious $$$ and I am wondering if I can substitute something more common sensor and connector. Having the temp/resistance table is the key. The title of the image says A4. Do you know if this is the same spec for the M6 sensor?

Thanks, Scott

It's been a while since I read up on this but, IIRC, the A4 and Z06 use the same sensor. Here's the Z's schem.
