After puzzling over my Cat and Allison manuals, and getting nothing but confused, your explanation just made the light bulb light up. Now, why can't these clowns who write the manuals make it as clear as you have done? THANK YOU!!!!!

On our recently purchased 2005 Endeavor with 400 HP Cummins, pushing the mode button does not turn the light on. Don't know if supposed to or not applicable on this model.

Welcome to the FMCA Forum.

Easy to test:

Accelerate in power mode, noting max engine RPM in each gear.

Do the same with the mode button on.

If the shifts are at lower RPM with mode on, it is working-- and perhaps the bulb is bad???

Let us know what you find.

Certainly, any Allison dealer can connect their computer and tell you.

Have 2006 HR Neptune with an Allison 5 spd, with a Cummins ISB 300. Transmission manual recommends not using in economy mode in city driving or mountains. What is your opinion?

Welcome to the FMCA Forum.

You might go back to the first post in this topic-- it covers the HOW it works and my observation on how I use it.

The how it works is FACTUAL. The WHEN to use is is based on our individual preferences/opinions.

We just drove home from Albuquerque-- used economy mode 100% of the trip. If I had hit a passing situation on a two lane road where I would be happy to trade a lot of fuel for a little more performance, I would have selected power mode for that situation.
