Preventive Maintenance Overview
To keep the vehicle running properly, it is important to perform preventive maintenance on vehicle components. This
ensures the vehicle and its subassemblies will operate properly throughout their useful life. To cover preventative maintenance completely, you must review the following subjects in detail:
1.Recommended Lubricants
2.Maintenance/Lubricant Change Interval
3.Inspecting the Transmission
4.Changing the Fluid
5.Vehicle System Effects
Recommended Lubricants
Where transmissions are concerned, lubricant is possibly the most important part of keeping a vehicle operating.
Lubricants which meet the Eaton E500 (PS-164) specification are required in the AutoShift transmission. Lubricant
must be approved by Eaton Corporation to qualify for the 5/750,000 warranty. For a list of Eaton Roadranger approved
lubricants, order publication TCMT-0021.

Page 8
General Information
Maintenance/Lubricant Change Intervals
IMPORTANT
Transmission filters should be changed durning regular lube intervals. Inspection of the transmission filter should
be conducted during preventative maintenance checks for damage or corrosion. Replace as necessary.
Transmission inspections and lubricant changes depend on the type of lubricant used and whether the vehicle is used
On or Off-highway.
On-highway Lubricant- Vehicles operated on paved roads, interstate highways, and turnpikes are designated as onhighway vehicles. Lubricant change and inspection intervals are the most generous for on-highway vehicles using synthetic lubricants.
Off-highway Lubricant- Vehicles operated in off-highway applications such as coal trucks or mining vehicles, it is more
important to use time rather than mileage to keep the transmission within its proper preventative maintenance schedule. Off-highway applications are divided into two categories, severe and normal. “Severe off-highway” is the designation used when there is excessive dust and dirt. “Normal off-highway” is for applications where dust and dirt are
minimal.

Transmission Inspection
When performing preventive maintenance (PM) inspections, several items must be checked. It is important to perform
every step to ensure the transmission will meet its life expectancy. Proper PM consists of the following steps:
1.Check Lubricant Level
2.Inspect for Loose/Missing Bolts
3.Check for Air Leaks
4.Check for Lubricant Leaks
Check Lubricant Level
When checking the transmission lubricant there are two important points to know: where to check the lubricant and
what the proper lubricant level is. Always be cautious when checking the transmission lubricant as it may be hot.
Checking Location- Checking the lubricant at the lubricant fill plug located on the left side of the main transmission
case.
Proper Lubricant Level- The lubricant is at the proper level when it is even with the bottom of the fill hole. When you
remove the plug to check the lubricant level, lubricant should seep out. Do not use your finger to feel for the lubricant.
Even if you can touch the lubricant, it may not be at the proper level. In a transmission, one inch of lubricant level equals
about one gallon of lubricant.

Inspect for Loose/Missing Bolts
While you are under the vehicle checking the lubricant, make a quick check for loose or missing bolts. Check all bolts on
the back box, PTO covers, shift bar housing, clutch housing, and transmission controller. Replace any missing or broken bolt with the proper bolt as specified in the Illustrated Parts Listing. Follow the procedure defined in the transmission Service Manual when tightening any bolts.

Page 10
General Information
Check for Air Leaks
Two steps are required when checking for an air leak: inspection and repair.
Audible Inspection for Leaks- To find air leaks, make sure the vehicle air system has at least 90 PSI air pressure. Then,
listen for leaks, making sure a vehicle leak is not mistaken for a transmission air leak.
Refer to Troubleshooting Procedures- Once you find an air leak, use the Troubleshooting Guide to isolate the air leak to
the faulty component.
Check for Lubricant Leaks
A lubricant leak could cause a catastrophic transmission failure. Check for leaks first at the gasket surfaces, then the
input shaft, the rear seal, and the transmission cooler.
Gaskets- Visually check each gasket to insure that no leak is present. Typically a moist spot is acceptable; however drips
or larger wet areas are not. Check for leaks at the rear housing, PTO, shift bar housing, shift tower, and clutch housing
gasket surfaces. It is also important to ensure that the leak is indeed coming from the transmission. Make sure the oil is
not being blown back from the engine or another vehicle component.
Input Shaft- Check for leaks around the input shaft. Leaks in this area could be caused by a faulty gasket, input shaft, or
pressurization of the main transmission case by the air system. If you find a leak at the input shaft, make sure the air
system is not leaking into the case before looking for leaking gaskets.
Rear Seal- The rear seal is very important in maintaining lubricant in the transmission. If the seal is improperly installed
or has failed, the transmission may experience a catastrophic failure. Check the rear seal by performing the following
steps:
General Information
Visual Check for Leak- Visually inspect the rear seal for a leak. If a rear seal leak is suspected, proper isolation is necessary.
Verify the Leak Path- Other leaks may give the impression the rear seal is leaking. One possible cause is the vehicle
speed sensor. Any lubricant leak above and in front of the rear seal could cause lubricant to collect around the seal.
Wipe the seal with a clean rag, operate the vehicle, and recheck to verify the leak path. More information can be found in
the Seal Maintenance Guide (TCSM-0912).
Transmission Cooler Leaks- If the vehicle is equipped with a transmission cooler, make sure there are no leaks at the
lubricant cooler, hoses, and fittings of the cooler circuit.

General Information
Changing Lubricant
When it is time to change the transmission lubricant, there are only a few steps to follow: Draining and filling the transmission, draining and filling the cooler (if equipped), and changing the lubricant filter (if equipped). Remember to be
careful when changing the transmission lubricant, as it may be hot.
Drain the Transmission
1.Locate the drain plug on the bottom of the transmission case.
2.Place a drain pan under the drain plug.
3.Remove the drain plug and allow the lubricant to drain completely.
4.Once drained, reinstall the drain plug and tighten to 45-55 lbs.ft. (61.0-74.6 N•m). Sealant is not required on
the drain plug threads.
Drain the Cooler (if equipped)
1.Remove both cooler lines at the transmission.
2.Pressurize one line with 30 PSI of air pressure to force the lubricant out of the cooler.
3.Once drained, reconnect the coolant lines to the transmission. Make sure the lines are not crossed.
Fill the Transmission
1.Remove the transmission fill plug and fill the transmission with approved lubricant.
2.The transmission is full when the lubricant starts to flow out of the fill hole.
3.Replace the fill plug and tighten to 60-70 lbs.ft. (81.3-94.9 N•m).
Fill the Cooler (if equipped)
1.Place the transmission in neutral and start the vehicle.
2.Release the clutch to rotate the input shaft of the transmission, allowing the pump to fill the cooler.
3.Run the vehicle for one minute.
4.Shut off the vehicle, recheck the transmission lubricant level and add lubricant as required.
Change the “Spin-on” Filter (if equipped)
1.Remove the filter from the “spin-on” casting.
2.Catch any lubricant that seeps from the filter.
3.Clean the casting surface.
4.Install a new filter and hand tighten.

General Information
Vehicle System Effects
Some vehicle systems can affect the transmission operation and possibly cause a failure. The air system is a major system that can affect the transmission components.
Air System- If the air system is not given recommended preventive maintenance, it can cause problems for the transmission system. Although the transmission has an Air Filter/Regulator, it can only protect the transmission from contaminants for so long. This is why it is important to follow OEM recommendations for air system preventive
maintenance. It is important to regularly drain air tanks and ensure lubricant is not being pumped into the system. It can
cause corrosion or, in cold climates, it could freeze and prevent the shift mechanisms from operating. If lubricant is
allowed into the system, it could fill the air system components and cause them to lose valuable air volume, slowing or
preventing movement.

Check Lubricant Level
When checking the WetClutch model, there are three important things to know: where to check the lubricants, what is
the proper lubricant level, and what is the proper lubricant type. Always be cautious when checking the transmission
fluid since it may be hot.
General Information
Checking WetClutch Lubricant
The WetClutch portion is checked using a dipstick located in the engine compartment.
Proper WetClutch Lubricant Level
WetClutch lubricant level should be checked when idling in neutral, with the transmission temperature between 60° F
and 120° F (15.5° C and 48.8° C) and when the vehicle has been idling in neutral for at least two (2) minutes. Proper
lubricant level is obtained when the lubricant is between the cold ADD mark and the cold FULL marks on the dipstick.
Due to thermal expansion of the lubricant, it is not recommended to check the level when the transmission is above
120° F (48.8° C).

Proper Gearbox Lubricant Level
The gearbox lubricant is at the proper level when it is even with bottom of the fill hole. When you remove the plug to
check the lubricant level, lubricant should seep out. Do not use your finger to feel for the lubricant. Even if you can
touch the lubricant, it may not be at the proper level. In a transmission, one inch of lubricant level equals about one gallon of lubricant.

Inspect for Loose/Missing Bolts
While you are under the vehicle checking the lubricant, make a quick check for loose or missing bolts. Check all bolts on
the PTO cover, inertia brake, shift bar housing, clutch housing oil pan, output flange, and transmission controller.
Replace any missing or broken bolt with the proper bolts as called out in the illustrated parts listing. Follow the procedure defined in the transmission service manual when tightening any bolts.
Check for Lubricant Leaks
A lubricant leak could cause a catastrophic transmission failure. Check for leaks at the gasket surfaces, lubricant lines,
flywheel housing, rear seal, and the cooler.
Gaskets
Visually check each gasket to ensure that no leak is present. Typically, a moist spot is acceptable, however, drips or
larger wet areas are not. Check for leaks at the rear housing, PTO cover, shift bar housing, clutch housing to main case,
inertia brake, and clutch oil pan. It is also important to ensure that the leak indeed is coming from the transmission.
Make sure the lubricant is not being blown back from the engine or another vehicle component.
Lubricant Lines
There are three external lines for lubricant on the UltraShift HP transmission. One lubricates the inertia brake and the
other two are for the oil cooler. Check the lines to ensure they are not leaking.
Flywheel Housing/Clutch Housing
Check for leaks around the flywheel housing/clutch housing mating surface. A faulty seal or loose fittings could cause
leaks in the area. The UltraShift HP transmission has what is called a “wet housing” which means that the clutch housing is used as a sump for the WetClutch lubricant. Any leaks here could cause a transmission failure.

•Draining and Filling the Cooler,
•Changing the Lubricant Filters
WARNING
Remember to be careful when changing the transmission lubricant, as it may be hot.
Drain the Transmission Gearbox and WetClutch Housing
1.Locate the drain plugs at the bottom of the transmission gear case and on the clutch housing oil pan.
2.Place a drain pan under each drain plug.
3.Remove both drain plugs and allow the lubricants to drain completely.
4.Disconnect both cooler lines at the WetClutch housing.
5.Pressurize one line with 20 PSI until all lubricant is forced out of the cooler.
General Information
6.Reconnect both cooler lines.

General Information
Change WetClutch Filters
Change the lubricant filters when the transmission lubricant is changed. Detailed information can be found on removal
and replacement of the oil filters in this service manual.
Fill the Transmission
1.Install the transmission gearbox drain plug and tighten to 45-55 lbs.ft. (61.0-74 N•m). Sealant is not required
on the drain plug threads.
2.Install the clutch housing oil pan drain plug and torque to 34-48 lbs.ft. (46-65N•m). Sealant is not required on
the drain plug thread.
3.Fill the transmission gearbox with the recommended lubricant until the lubricant seeps out of the fill hole.
4.Install the fill plug and torque to 25-35 lbs.ft. (34-47 N•m).
5.Slowly fill the clutch through the dipstick tube with a maximum of 18 pints (8.5 liters) of the recommended
lubricant.
6.Place the transmission in neutral position and apply the parking brakes. Start the engine and let idle for five (5)
minutes, (this allows oil to fill the WetClutch system and cooling system), add oil as needed to obtain a level at
the proper temperature range. Total oil quantity should be approximately 24 pints: this varies depending on the
cooling system capacity.
7.Increase the engine idle slowly to 1500 RPM for two (2) minutes. Next, recheck the oil level at normal idle
speed in neutral, again adding oil to obtain a level at the proper temperature range.
8.Replace the dipstick and tighten securely.
Clutch Calibration
The UltraShift HP system automatically provides for clutch wear. The system will initiate a clutch calibration once per
vehicle power up, when certain vehicle conditions are right. Of these conditions, the most important ones include: when
the engine is running at idle speed, during normal operating temperature, when the vehicle is stopped, and when neutral
is selected on the Shift Control. During the calibration, the clutch is partially engaged until the engine begins to slightly
lug down. It will then disengage the clutch and repeat this process several times. The calibration process usually takes
as little as thirty seconds but can take as long as two (2) minutes. The calibration will be aborted when any position
other than neutral is selected on the Shift Control.
If it appears that the vehicle is not engaging smoothly from a stop, it is possible that the clutch needs to be re-calibrated. If it has not been previously calibrated during the current power up, stop the vehicle with the engine idling at its
normal operating temperature and place the Shift Control in neutral and wait two (2) minutes. If the calibration is being
performed you should hear the engine slightly lug down and then return to its no load condition several times.
If calibration does not occur a Power Down/Power Up will initiate a calibration.
