I have to ask why you need something else to get anxiety over? Choices are to drill the pan and use a bulkhead fitting or drill the side of the housing and tap for the 10mm or 1/8-17 pipe thread for the sender chosen. These transmissions rarely give trouble and when they do repairs are not that hard. Overheating is usually a sign of failure or abuse.

Subject: Auto tranny cooling

I would like to install a temp guage to monitor the tranny oil temp but don't know how to approach this.  Has anyone done this ? Can you describe it or provide a link?

Thanks,

John
