Transynd Fluid Change Interval

 


Transynd

After years of TranSynd™ synthetic transmission fluid usage in all sorts of Allison automatic transmission applications, it has proven to exceed original requirements and expectations.

Depending on the vocation and duty cycle, extended drain interval guidelines for TranSynd™ are up to 300,000 miles/48 months/6,000 hours for general duty and up to 150,000 miles/48 months/6,000 hours for severe duty.

Compare that to recommended drain intervals for conventional transmission fluid – 25,000 miles/12 months for general duty and 12,000 miles/6 months for severe duty.

Purely remarkable endurance

Conventional transmission fluids have performance additives blended in – friction modifiers, anti-wear agents, antioxidants, dispersants, detergents, rust/corrosion inhibitors, seal swell agents, anti-formants and more. But, because the base fluid is petroleum, conventional fluids do not provide the thermal resistance of TranSynd™.

With extended use, petroleum based fluids react to oxidation much faster and more detrimentally, overwhelming the effectiveness of the dispersants and detergents. The oil thickens and becomes more acidic. Mechanical stress leads to shear, resulting in permanent viscosity loss. Thinner oil means less lubrication. Sludge and varnish deposits erode shift quality and clutch durability, causing increased component wear.

TranSynd™, on the other hand, is formulated from pure synthetic lubricants with inherent thermal and viscosity advantages. Performance additives are then tailored to the unique molecular structure and excellent antioxidant properties, resulting in a lubricant that is far more chemically and physically stable than other oils and virtually imperious to shear.

Nothing protects better

The fluid in an Allison Automatic is more than just a lubricant; it’s a critical component of the transmission. It literally transmits energy between the engine and driveshaft, removes heat, lubricates, enhances seals, protects, and acts to maintain constant friction properties between friction plates and reaction plates. TranSynd™ fulfills all of these functions far better than conventional automatic transmission fluids.

Liquid Asset

By greatly extending drain intervals, TranSynd™ helps lower the costs for maintenance and downtime. You save on the cost of transmission fluid, replacement filters, the disposal and liability of used fluid. Most importantly, you benefit from reduced wear, better performance and longer service life from your Allison Automatic. Bottom line: the superior lubricating protection of TranSynd™ results in even greater productivity and lower operating expenses.

NOTE: Change fluid/filters at or before recommended mileage, months, or hours have elapsed, whichever occurs first.

NOTE: Local conditions, severity of operation or duty cycle may require more or less frequent fluid change intervals that differ from the published recommended fluid change
intervals of Allison Transmission. Allison Transmission recommends that customers use fluid analysis as their primary method for determining fluid change intervals. In
the absence of a fluid analysis program, the fluid change intervals listed in the charts above should be used.

NOTE: General Vocation: Intercity Coach with duty cycle less than or equal to one (1) stop per mile and all other vocations not listed in severe vocation.

NOTE: Severe Vocation: All Retarders, On/Off Highway, Refuse, Transit, Shuttle Transit, 2000 MH, and Intercity Coach with duty cycle greater an one (1) stop per mile.

When seeking a fluid for your Allison transmission that is TES 295 approved do not fall to the claims of some companies that claim that their product is TES 295 approved. The statements infer that these products "are designed to meet", "are equivalent to", "meet or exceed", etc. When determining whether or not a fluid is TES 295 approved, look and/or ask for one of two things:

# The Allison TES 295 approval number

# The Allison Approved logo

SERVICE BULLETIN  - Foretravel 2003

Date: 08/26/02

Subject: Service Allison Transmission 6 Speed (3000/4000)

Bulletin Number: M001063

Models Beginning with the first 2003 model.
Foretravel uses TranSynd Transmission fluid as the initial factory fill. The use of the new gold series filters introduced by Allison Transmission will allow the transmission service intervals be extended to 75,000 miles or 36 months.

The initial main filter change will be required at 5,000 miles.

The next scheduled transmission service will be required at 75,000 miles or 36 months whichever occurs first.

The initial main filter change will require approximately 2-3 quarts of fluid for the MH3000 and 4-5 quarts for the MH4000 series.

2002 Model and Older Foretravel Motorhomes earlier than 2003, the following customer options apply.

If a customer elects to use TranSynd Fluid to obtain the extended service interval, the following applies:

(1) Make the initial change to TranSynd and the Gold Series filter.

(2) Change the TranSynd and filters at 12,000 miles or 6 months.

(3) After the second change, the intervals will be as listed for TranSynd users, or 75,000 miles or 36 months, whichever occurs first.

The initial main filter change will be required at 5,000 miles. The main filter can be identified having “MAIN” embossed on the filter cover.
The main filter will be located on the opposite side of the transmission from the drain plug.

The amount of fluid collected from the removal of this filter should be measured and that amount should be reinstalled in the transmission

This will complete the initial service procedure for the 2003 Model.

Part Numbers:

Main filter-29540496 (initial change with TranSynd only)

Full filter kit-29540494 (All changes other than initial with TranSynd)

TranSynd-27101CTCS (1Gallon Container)
