Allison not hot enough to check fluid level?

I have seen many mentions of using the shift pad to check fluid level in the Allison transmissions. As most folks know, the trans must be up to operating temperature before this function is available at the shift pad, and a lot of folks have said they have trouble reaching that temperature, especially in cool weather. Here is what I do.

Check your fluid after taking your coach out for its monthly "exercise" (assuming your coach sits a lot, like many of us). But if it still is not up to temp, hold the coach back with your service brakes, and with the trans in "Drive", apply a small bit of throttle. The fluid churning in the converter will raise the temperature very quickly and your shift pad will let you perform the fluid level check.

That's seems a but abusive to the Trans. The thermal expansion of transmission fluid is like 0.043% per 100 deg change in temp. Which most run at 175deg so 100 is about the normal increase in temp from ambient. But if you drive it and its less than 175 by a few deg it won't make that much difference.
For 5 gallons of fluid to get up another 25 deg will change the level about 1/5 of a quart.
Just my .02 cents

Why not check on shut down? Temp is up and unless you see a puddle at next start up there is no place for the fluid to go.

Ok. Can someone please tell me how to check the oil level in the tranny by the pad. I didn't know you could do that.
Thanks

Monthly "exercise" ??
Does anyone actually do that?
My coach sits for months each year, (some years for 5-6 months at a time), and has for 18 years.
It has never been "exersized", (unless it's going somewhere).

Both Cummins and CAT recommend that their engines remain "off" unless they can be brought to full operating temperature. There is no reason to turn them on. Ours wasn't run from the beginning of November last year through mid-March and it started up without any problem. Think about how many pieces of farm and construction equipment sit around for months on end awaiting the next growing or highway construction season.

The transmission oil temperature has to reach 140 deg. It's quick and easy to accomplish that by engaging the Park Brake, place the transmission in Drive, set cruise control for a gentle high idle (no more than 900 RPM). This will warm the transmission in only a few moments, and then the shift pad will work for displaying the oil level.

I'm going to have to do this sometime soon. My transmission has an electric cooling fan, and it is not engaging, which means the transmission oil is getting too hot when the transmission is under load on the road. To date, I can't find out why. The only way I can trouble shoot it is to warm up the transmission to the right temperature.

FWIW there is a dipstick. It has cold and hot ranges and will work to check level.

Rob what Van susgest on warming the Trans up will not abuse it, that is a simple way to warm it up.

Jim unless its been changed your cooler should be a Wax valve by Sauer Danfoss, I will past a link someone posted a year or so ago on a company in England that sell the Wax valve for less than 1/2 the price in the USA or they did at the time.

Allison recommends checking the transmission fluid level electronically.

The coach builder supplies the transmission fluid dipstick, (not Allison).
Unless your Allison dipstick has been re-calibrated there is a good chance that the "cold and hot" and/or "full/add" marks on it are WRONG.

(BTW, the same is true of the engine oil dipstick.)

To add on to what Mel stated about Allison dipsticks, some coaches only come with a "shorty" that cannot be used to measure the level. It's there to plug up the fill tube opening only.

Allison recommends using the shift-pad only as its algorithms are temperature compensated.
