It is a good idea for a temp guage,I have a Gryphon programmer that can moniter the temp.As far as the cooler I have a 2002 F250,most people recomend to switch to a 6.0 cooler from a 7.3 a big differrence in size.I also tow a 44ft box trailer.

I agree with ford trans tech. I have my sensor mounted in the outlet line and belive its the best place because you see the max temp you transmitions internals are getting to and for how long. The fluid in the pan just came back from the cooler then gets sucked threw the trans preforming hydraulic functions as well as removing heat from the internal parts then gose to my sensor to tell me the temp of the parts.
I also belive in keeping the rad cooler. Ideling at a stop light with the trany in gear will cause a massive build up in heat in the trans and you have very litle air flow across the air cooler.

There is some great info in this thread, Thanks guys.
What is the max temp you should let it get to before pulling over to let it cool? What is the best way to cool it down? Pull over and let it idle or just completely shut it down?

160-175 deg. is considered normal and you can expect an oil life of 100,000 miles. For every 20 degree increase in temp. it cuts the oil life in half. At 195 oil starts to shelac or tarnish. At 250 seals harden and start to leak. above 250 clutches start to slip. Somebody in a post just a mth or 2 ago had a real nice chart, breaking it down real nice. Sorry I couldn't find it. Found this info after lots of searching on the net., from one of the oil manufacturers. None of them specify how long it takes at rated temp. to create damage but it's probably not long.
