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

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.

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
