Max retarder temps?

[tommy.rountree]

When I thought I had a tranny issue on a long trip last Christmas,(temp went to
230 degrees and the red warning light came on) I stopped and called Allison. The
tech came out and inspected my transmission. Nothing appeared to be wrong.
Turned out it was the fan alarmstat. Anyway the Allison man said use the
retarder judiciously, preferably on "enable" rather than "apply" and run the fan
on "manual override" as the temp increases. He said the tranny could go to 350
degrees, but he strongly advised against it.

Now, new alarmstat, judicious use of the retarder on enable only and the fan on
override and I very rarely go over 200 degrees. For what it is worth.
