How To Reset Allison Transmission Oil Life

Video How to reset allison transmission oil life Often the key to a successful repair is simply a matter of experiencing the symptoms your vehicle is exhibiting or understanding the theory of how your system works. Processing. -, and now a 10-speed unit called the TC10. Many stores hesitate to offer some of the larger units, such as the Allison 3000 or 4000 series. Although these gearboxes are largely designed with their smaller brethren, the 1000 series units. and 2000 are slightly different in some areas. . The type your vehicle is fitted with is usually based on GVW (Gross Vehicle Weight), horsepower and engine torque.While most technicians are comfortable with the 1000, 2000, 3000, 4000 and B-series terminology, it’s not quite so straightforward. Allison also has sub-serial numbers, a good example is the 2000 serial unit number. In the 2000 series there are many sub-series units, such as 2000, 2100, 2200, 2350, 2400 , 2500 and 2550 just to name a few. The difference between these sub-sequences may or may not be significant. Alternatively, the unit can be one of five generations in that substring. Several generation updates are interchangeable; others do not. Some features may also vary from year to year as well as from model to model, so it is important to accurately identify the device. Like the other units, the Allison app has a tag that provides the serial number and model number on the original app. Later model units may not include the model number, so you may have to check the serial number to determine which model it is. The first two digits will help you identify the unit:

  • 63XXXXXXXX = Line 1000/2000
  • 65XXXXXXXX = Line 3000
  • 66XXXXXXXX = 4000 Lines

Another way to determine the unit is with your scan tool. The scan engine will usually list the Transmission Voice Model, such as 3000 RDS, 2500 PTS (figure 1). or the type of service the link is designed for. Let’s look at 3000 RDS as an example (Figure 2).lookforinfo 2If you are dealing with a feeder bus, it can become more confusing. Transit buses are designated with the prefix B followed by three additional digits. So the B 400 represents a unit that can be used in a city bus.

Many Allison computers are equipped with prognostic software, which can be turned on or off. In our 3000 series example, the system is designed to monitor liquid levels and DTCs across most applications. In 2009, features were added to the prognostic software, including:

  • Life flows smoothly
  • Filter life
  • Transmission Health

You can display prognostic information through your onboard diagnostics or scanning engine. When servicing the Allison, you will need to reset some prognoses or settable DTCs.Liquid level – Liquid level monitoring system by liquid level sensor attached to the valve body. The sensor is designed for 5 volts, with values ​​ranging from 0.5V to 4.5V, depending on the liquid level. Not all applications or years are equipped with a liquid level sensor. If the device is not equipped with a liquid level sensor, the liquid level will not be available.DTC – The computer can display the DTCs using the on-board diagnostic and scan data. How it formats and displays the DTC using the onboard diagnostics depends on the transmission generation and the design of the shifter.Fluid life / Filter life Similar to engine oil life monitoring, TCM uses a countdown timer to let you know when it’s time to change the transmission oil. When the timer reaches 2%, the system displays the message “change transmission fluid”. The system determines filter life by monitoring the pressure drop across the cooling filter circuit. If the filter is restricted, the computer will display the message “change transmission filter”.Transmission Health – Computer monitors shift adaptive values ​​to determine transmission clutch health. If the displacement adaptive values ​​reach 10% of the adaptive programmed maximum value, the TCM will display a “low line health” message. The prognostic system displays the status of each clutch used. When the computer recognizes that a prognostic service is needed, the wrench icon will light up on the shift lever display. Depending on what’s wrong, the wrench icon may blink (filter life), stay lit (line condition), or stay lit only for the first two minutes of operation (operating time). You can retrieve prognostic information with the scan tool or through on-board diagnostics. The on-board diagnostic system can communicate through the gear shifter. Several designs and generations of gear shifters have been used, so access to information will vary slightly. Button and lever designs were used. If the shifter does not use a cable, you can access the prognoses through the shifter display.

PUSHBUTTON SHIFTERS

You can access the button displacement prognosis by pressing both the up and down arrow buttons simultaneously (Figure 3). Once you have access to the diagnosis, you can choose what prognosis level, depending on how many times you press the up/down arrows.

  • Oil level: Press the up/down arrows simultaneously.
  • Oil life: Press the up/down arrows twice at the same time.
  • Filter life: Press the up/down arrows three times simultaneously.
  • Line Health: Press the up/down arrows four times simultaneously.
  • DTC: Press the up/down arrows five times simultaneously.

ELECTRONIC SHARE SET OF TYPE LEVER

You can also use a lever-type gear lever to access the prognoses, as long as they are not equipped with a cable. To open the menu, press the diagnostic button (Allison logo) on the lever.

  • Oil level: Press the diagnostic button once.
  • Oil life: Press the diagnostic button twice.
  • Filter life: Press the diagnostic button three times.
  • Transmission status: Press the diagnostic button four times.
  • DTC: Press the diagnostic button five times.

The 5th generation unit (2013 and up) is easy to understand, as all information is displayed in a language format.lookforinfo 3Generation 4 (2006-2012) units are a bit more difficult, as the screens are segmented. Previous generations only showed the oil level and the DTCs; you will need to access service information to help decode the screens. The oil level and DTC display will vary, depending on the computer.Oil level: Initial applications will require a chart to help you isolate any oil level problems. If the oil level is correct, it will be displayed as OL, OK or “Oil level OK”.DTC: Depending on the display design, the DTC will be displayed in the following sections: D1 = first code, P = powertrain code, 07 = first two digits, 22 = last two digits, first DTC set P0722 . If additional DTCs are set they will obey or pressing the mode button will access the next code. On later designs, the DTC will simply display as P0722.Oil life: Oil life will be displayed as a percentage, such as O, 50 O = for 50% oil life (GEN 4); Generation 5 units display as “50% Oil Life”.Filter life: The filter status on GEN 4 units is shown as F, OK, F = filter. OK indicates the filter is not restricted. On GEN 5 units, it will be displayed as “Oil Filter OK.”Transmission Health: Transmission health status on GEN 4 units is displayed as T, OK: T = Transmission, OK indicates transmission clutch is still active within parameters; The LO indicates that there are clutch-related problems. GEN 5 units will display “Transmission Status Ok” or “Transmission Status”. As with most integrated diagnostic systems, additional information is available through a scan tool. Although scan diagnostics is a desirable method, on-board diagnostics can be useful when a scan tool is not available.

RESET OIL LIFE, FILTER WITH TABLE DISPLAY

To reset the oil and filter life, you can use your sweep tool, but there are other methods. One way to reset oil life involves the Mode button on some shifter designs. After accessing the oil life display, press and hold the Mode button on the shift lever for 10 seconds. Another method is to turn on the key, turn off the engine and then move the shift lever between NDNDNRN. Filter life follows the same basic process, with one exception: shift lever movement to reset the filter screen. To reset filter life, visit the filter life screen. With the key on and off the engine, moving the shift lever between NRNRNDN As you can see, working on a larger Allison is not that difficult. Yes, there are a few differences, but for the most part, they are very much like little brothers. Until next time, remember: Success is where preparation and opportunity meet.
