Transmission oil temp sensor location??

[jwalka51]

I currently have a borg warner 72 series in my boat. Gonna be re-powering soon with a john deere 4045 and a twin disc 5050. But in the meantime, I am going to need to run what I have until I can afford to do the change over at the end of this season.
So, I would like to add a transmission temperature gauge so that I can moniter the tranny and catch trouble before it really gets bad. I am trying to locate where the temp sensor should go. I am not sure if there is a port right on the tranny where I could install it. If there isnt one, would it be ok to put a tee in the oil line going to the tranny cooler(the feed line of course) and put the sensor in the tee??? Has anyone ever done this?? And will I get an accurate reading.???? Thanks guys

how about just putting a pressure gauge on?

Yes I did it that way and it works great. I also installed thermostatic valves and pall filters becuase I have trolling valves. The gears stay right at 150.

My only regret was not using murphy switch gauges so I have no alarm on the gear temp.

By the time you loose pressure the gear is fried. If you see the temp going up and shut it down you could save it.

Because I want to know if my gear is over heating. Thats the first sign of a problem and if you can catch it early, then you may avoid completely destroying the gear. I dont really care about pressure. If the gear looses pressure you will notice it slipping, Generally it will lose pressure after it has already overheated.

I think your best bet is to get the HP rating of your gear & the HP rating of the 4045 you have selected. next do not run the vessl at a higher RPMs that the gear is rated for.
As far as the gauge goes this is how I did mind and it work fine. I Tee it off the pressure line of the oil cooler
