TF999 Cooling & Temp questions

What's the best way to know if your trans is running hot? I have a newly installed auto in my rig and had no radiator connects so I bought a aftermarket cooler and installed it in front of the radiator as far as possible. But is that enough?
Should I add a electric fan to it?
How can I monitor the temperature?

That is more cooling power than it has ever had before. I would not worry about it.

Sure would be nice to see the temp wouldn't it?

It would be a gauge that would probably be boring to watch. I guess you could install an inline water temp gauge using a water temp sending unit.

Newer cars have a trans over temp monitored by the automatic tanny brain

Think about this for a minute.... Most cars go to the scrap heap with a ton of miles on the odometer and no one has ever pulled the tranny dipstick.

Tranny fluid is a highly refined oil that does not suffer from the ill effects of combustion. It gets hot but from friction not combustion.

I did pick up a deep pan from quadratec last week. Its deep enough to drill and weld in a bung for a temp sensor. I just need to find a metal one I can weld in. I think it would be a good tool to see how hard the trans is working.

There could be an issue with a temp sensor hanging down from your transmission base pan. Most transmission base pans are all but flush with the base of the transmission. So your trans temp sender would be exposed downward towards the pavement. Think about the possibility of snapping it off if you drive over a curb or if you hit a pot hole. Forget about any off road use.

If I wanted to check the temp of my tranny fluid I would install a threaded brass T to screw in the temp sender inline where the tranny fluid goes to the radiator to be cooled off.

No I already spent some time locating the best location. It would screw in the rear horizontally. Nothing would be hanging down at all. I'll include a right up with pics when I go forward.

If you have the room in the base pan where the sending unit doesn't hang down proud of the trans base pan face that would be good.

Auto meter and Stuart Warner make Tranny gauges. A water gauge wouldn't go high enough. Most trannies run high. Aw4's run 200- 350 a lot especially off road.
I used an auto meter gauge and put the sensor in a tee connector at the Tranny on side that goes to the cooler.
