[VAC] Re: Transmission Oil Temp and Use of OD

[Jim Dunmyer <jdunmyer@xxxxxxxxxxx>]

Mark,
 I've seen all kinds of recommendations on where to place the
temperature probe for your trans temp guage, including strapping it onto
the dipstick tube. Mine is in the pan because that was easier than
installing a 'Tee' fitting in a cooler line, and one theory says that
the pan is the best place because that's the temperature that the
transmission sees. It won't be "cool because cool fluids sink"; the oil
is circulating fast enough that it's all pretty much the same temp, or
at least close enough. In fact, you would probably have seen the
overheating condition in your transmission had the probe been in the pan
instead of the return line. If I was to place it in a cooler line, I
think I'd put it in the line TO the cooler.

You're right about heating the trans quickly when maneuvering at a
campsite, and I'll bet most folks would never guess that this is a
dangerous situation. One usually thinks of pulling a hill as being
dangerous for trans temps.

The most important thing is to have a trans temp guage and monitor it.
The exact location of the pickup probably isn't that important, but I
wouldn't have it in the cooler return in any event.
