Detroit Diesel Series 60 Engine/Allison 6 speed operating parameters
#1

Hi all,

lets help each other and newbies with what are the operating parameters for our engines and trannys. once we get a kinda consensus and list of things and ranges, i will collate the data into a single post. no warranties implied, use data at your own risk, etc.....just our combined experience.

please add as you want, what you want to know and what you do know

also if you are referring to the gauges or the vmspc (ddec)

Engine Temp
Oil Temp
Trans Temp
Oil Pressure
Turbo PSI
RPM's

Also how to operate the Allison tranny optimally. the modes and how to check fluids via the keypad.

Just thought I would post some of the operating parameters of my series 60 on a 78 degree day in hilly conditions. All of these are taken from my VMS as many of the gauges are unreliable.

Engine Temp--192 to 195 degrees
Oil Temp--187 degrees
Trans Temp--189 to 192 degrees
Oil Pressure--48 to 50 lbs
Battery voltage--13.9 to 14.1 volts

The "mode" button changes the shift pattern of the transmission. I have experimented with it over a ten year period and have seen no benefit and no performance difference.

This pdf will explain using your keypad to check the Allison transmission fluid procedure. Go to page 19 for most of our keypads.

Steve, that is good information on what to expect. I am interested in what alarm settings you put into your VMS.

Misunderstood what was being asked for. I have set up no alarm settings on the VMS as I monitor the readings regularly.
