C5 z06. Trans cooler install. Temp sensor in drain rather than return?
Hi. Just finishing my trans cooler install. Similar to the DRM kit.
As standard the temp sensor goes in the fill hole. This becomes the return from the cooler typically with a t piece fitting to accommodate temp sensor and return oil line.
In this configuration the sensor is no longer in the gearbox and it would be reading the return oil temp not bulk box temp.
Any reason not to move it to drain / cooler feed location? Now your measuring bulk box temp. Only issue I can see is having the bulky t-piece in a more vunerable location on bottom of box.
