2–1. PERIODIC INSPECTION AND CARE

a. Transmission Inspection. Clean and inspect the exterior of the transmission at regular intervals. Severity of service and operating conditions determine the frequency of these inspections. Inspect the transmission for:

• Loose bolts—transmission and mounting components.

• Fluid leaks—repair immediately.

• Loose, dirty, or improperly adjusted throttle sensor.

• Damaged or loose hoses.

• Worn, frayed, or improperly routed electrical harnesses.

• Worn or damaged electrical connectors.

• Dented, worn or out-of-phase driveline U-joints and slip ﬁttings.

• Clogged or dirty breather (vent assembly).

• Check transmission ﬂuid for evidence of engine coolant.

b. Vehicle Inspection. Check the vehicle cooling system occasionally for evidence of transmission ﬂuid. Transmission ﬂuid in the vehicle cooling system indicates a faulty oil cooler.

PREVENTIVE

MAINTENANCE

c. Welding.

CAUTION: When welding on the vehicle:

• DO NOT WELD on the vehicle without disconnecting from the

TCM all control system wiring harness connectors.

• DO NOT WELD on the vehicle without disconnecting TCM

battery power and ground leads.

• DO NOT WELD on any control components.

• DO NOT CONNECT welding cables to any control components.

A label describing on-vehicle welding precautions (ST2067EN) is available from your authorized Allison service dealer and should be installed in a conspicuous place. A vehicle used in a vocation that requires frequent modiﬁcations or repairs involving welding must have an on-vehicle welding label.

2–2. IMPORTANCE OF PROPER TRANSMISSION FLUID LEVEL

Transmission ﬂuid cools, lubricates, and transmits hydraulic power. Always maintain proper ﬂuid level. If ﬂuid level is too low, the torque converter and clutches do not receive an adequate supply of ﬂuid and the transmission overheats. If the level is too high, the ﬂuid aerates—causing the transmission to shift erratically and overheat. Fluid may be expelled through the breather or dipstick tube when the ﬂuid level is too high.

2–3. TRANSMISSION FLUID CHECK

a. Electronic Fluid Check Procedure. Fluid level can be electronically displayed when the transmission contains the optional oil level sensor (OLS). Fluid level can be displayed on the shift selector or Allison DOC™. However, no oil level sensor diagnostics take place unless the OLS is “autodetected” by the

Allison 4

Generation control system. Frequently check for the presence of oil level diagnostics if the transmission is known to contain an OLS. If an OLS is not detected during the ﬁrst 49 engine starts, the control system concludes that no OLS is present. If an OLS is known to be present, but has not been detected, then troubleshoot the OLS circuit. After the OLS circuit is repaired, reset “autodetect” (refer to TS3989EN, Allison 4

Generation Controls Troubleshooting Manual for

detailed troubleshooting procedures).

• Displaying Fluid Level Information. Use the following procedure to display ﬂuid level information.

— For a pushbutton shift selector: Simultaneously press the ↑ (Up) and

↓ (Down) arrow buttons once.

— For a lever shift selector: Press the DISPLAY MODE button once. — For the Allison DOC™ diagnostic tool: Refer to the Allison DOC™

User Guide.

• Fluid Level Display Criteria. As soon as ﬂuid level information is requested, the TCM checks to see if conditions are right to allow display. Certain operating conditions must have been met for a period of two minutes before ﬂuid level is displayed. These operating conditions are:

— Engine at idle — Sump ﬂuid temperature at 60–104°C (140–220°F) — Transmission output shaft stopped — Transmission in N (Neutral) — Oil level sensor functioning properly

NOTE: To optimize the accuracy of the electronic ﬂuid level measurement, be sure sump temperature is in the normal operating range of 71–93°C (160–200°F).

If the two minute period has elapsed before the ﬂuid level data request, information is displayed immediately. However, if the two minute period has not elapsed, there will be a countdown display before ﬂuid level information displays. The countdown display ﬂashes constantly on the monitor digit. Countdown starts at 8 and decreases sequentially to 1 during the two minute period. When ﬂuid level data is requested, and the two minute countdown is in process, the ﬂashing display shows the number corresponding to the countdown progress. For example—if the ﬂuid level data was requested in the middle of the two minute countdown period, the display would ﬂasha5ora4anddecreaseto1.

• Shift Selector Display. Fluid level information is displayed two characters at

a time as in Table 2–1:

Table 2–1. Fluid Level Shift Selector Display

Display Sequence Interpretation of Display

oL oK Fluid level is correct

oL Lo 01 Fluid level is 1 quart low

oL HI 01 Fluid level is 1 quart high

The shift selector display will also show “invalid for display” codes two characters at a time. An “invalid for display” code is returned when ﬂuid level data is requested, but an operational condition has not been met. The “invalid for display” condition interrupts the two minute countdown (momentary increase in engine speed does not affect the countdown). The “invalid for display” codes and their meaning are:

Table 2–2. Invalid For Display Codes

Display Sequence Interpretation of Display

oL–50 Engine rpm too low oL–59 Engine rpm too high oL–65 N (Neutral) not selected oL–70 Sump ﬂuid temperature too low oL–79 Sump ﬂuid temperature too high oL–89 Output shaft rotation oL–95 Sensor failure

NOTE: Report sensor failure to a distributor or dealer in your area. Consult the telephone directory for the Allison Transmission distributor or dealer near you.

The countdown is restarted when the condition causing the “invalid for display” code is corrected. The countdown is not restarted if there is a momentary increase in engine rpm which may generate a code 59. “Invalid for display” messages are as follows:

• On Allison diagnostic tools, “Invalid for display” messages are shown in the Oil (±) ﬁeld of the Data Monitor.

Table 2–3. Invalid for Display Messages

DDR Message

OL — SETTLING TIME X OL — ENGINE SPEED LO OL — ENGINE SPEED HI OL — SELECT N (NEUTRAL) OL — SUMP TEMP LO OL — SUMP TEMP HI OL — OUTPUT SPEED HI OL — CHECK CODES

• Exiting the Fluid Level Mode. Exit as follows:

— For a pushbutton shift selector, press the N (Neutral) pushbutton once.

— For a lever selector, press the MODE button once or move the lever.

— For Allison DOC™, follow directions in the Allison DOC™ User

Guide.

b. Manual Fluid Check Procedure.

WARNING: To help avoid personal injury or property damage caused

by sudden and unexpected vehicle movement, do not check the ﬂuid level until you:

1. Put the transmission in N (Neutral).

2. Apply the parking brake and emergency brakes and make sure they are properly engaged.

3. Chock the wheels and take any other steps necessary to keep the vehicle from moving.

Clean all dirt from around the end of the ﬂuid ﬁll tube before removing the dipstick. Do not allow dirt or foreign matter to enter the transmission. Dirt or

foreign matter in the hydraulic system may cause undue wear of transmission parts, make valves stick, and clog passages. Check the ﬂuid level using the following procedure and report any abnormal ﬂuid levels to your service management.

c. Cold Check Procedure. The purpose of the cold check is to determine if the transmission has enough ﬂuid to be operated safely until a hot check can be made.

CAUTION: The ﬂuid level rises as ﬂuid temperature rises. DO NOT ﬁll above the “COLD CHECK” band if the transmission ﬂuid is below normal operating temperatures. During operation, an overfull transmission can become overheated, leading to transmission damage.

1. Park the vehicle on a level surface. Apply the parking brake and chock the wheels.

2. Run the engine for at least one minute. Shift to D (Drive), then to N (Neutral), and then to R (Reverse) to ﬁll the hydraulic system.

3. Shift to N (Neutral) and allow the engine to idle (500–800 rpm).

4. With the engine running, remove the dipstick from the tube and wipe the dipstick clean.

5. Insert the dipstick into the tube until it stops and remove. Check the ﬂuid level reading. Repeat the check procedure to verify the reading.

6. If the ﬂuid level is within the “COLD CHECK” band, the transmission may be operated until the ﬂuid is hot enough to perform a “HOT RUN” check. If the ﬂuid level is not within the “COLD CHECK” band, add or drain as necessary to bring it to the middle of the “COLD CHECK” band.

7. Perform a hot check at the ﬁrst opportunity after the normal operating sump temperature of 71°C–93°C (160°F–200°F) is reached.

d. Hot Check Procedure.

CAUTION: When performing the Hot Check procedure, the ﬂuid must

be at operating temperature to be sure of an accurate check and help prevent transmission damage. The ﬂuid level rises as temperature increases. During operation, an overfull transmission can become overheated leading to transmission damage.

1. Operate the transmission in D (Drive) until normal operating temperatures are reached:

• Sump temperature 71°C–93°C (160°F–200°F)

• Converter-out temperature 82°C–104°C (180°F–220°F)

• If the transmission temperature gauge is not present, check ﬂuid level

when the engine water temperature gauge has stabilized and the transmission has been operated under load for at least one hour.

2. Park the vehicle on a level surface and shift to N (Neutral). Apply the parking brake and chock the wheels. Allow the engine to idle (500–800 rpm).

3. With the engine running, remove the dipstick from the tube and wipe clean.

4. Insert the dipstick into the tube until it stops. Then remove it. Check ﬂuid level reading.

5. Repeat the check procedure to verify the reading.

NOTE: Safe operating level is within the “HOT RUN” band on the dipstick. The “HOT RUN” band is between the “HOT FULL” and the “HOT ADD” bands. Refer to Figure 2–1.

6. If the ﬂuid level is not within the “HOT RUN” band, add or drain as necessary to bring the ﬂuid level to within the “HOT RUN” band.
