Shell Lubricants Introduces Shell Donax TX

March 6, 2006

HOUSTON – Shell Lubricants has introduced Shell Donax TX, a heavy duty, semi-synthetic, automatic transmission fluid, designed for use in Allison Heavy-Duty Automatic Transmissions and those of other heavy-duty transmission manufacturers. Shell Donax TX fluid offers a high-performance optimized additive package that allows for extended drain intervals.

“Shell Donax TX fluid was developed in response to Shell customers’ requests for an extended-drain fluid for use in Allison Heavy-Duty Automatic Transmissions that recommend the use of a TES-295 fluid,” says Dan Arcy, technical marketing manager, for Shell Lubricants. “This new heavy-duty transmission fluid responds to those requests by allowing for extended drain intervals up to 100,000 miles in normal service.”

Shell Donax TX fluid has a drain period of 100,000 miles in regular service. Field trials of equipment fitted with Allison Heavy-Duty Automatic Transmissions have shown a drain period of 50,000 miles in severe service to be appropriate. If operators wish to extend the drain period beyond 50,000 miles in severe service, used oil analysis is required to determine the condition of the oil.

Shell Donax TX fluid does not have formal Allison TES-295 approval; however, Shell Donax TX fluid is suitable for use and will not harm Allison transmissions. Further, Shell guarantees the performance of Shell Donax TX fluid when the lubricant has been recommended by Shell for a specific application, and the lubricant is selected and maintained in accordance with the conditions required by Shell and is used under normal operating conditions in mechanically sound equipment. If a Shell Donax TX lubricant failure is found to be directly responsible for equipment damage, Shell will repair the equipment.

Shell Donax TX fluid is suitable for use in applications calling for:

  • Allison C-4
  • GM DEXRON®III (H) (H-36203)
  • Voith
  • ZF
  • MAN
  • All Allison transmissions requiring DEXRON-III, Allison C-4 or TES-295 fluids.
  • CAT six-speed CX31 transmissions, and eight-speed super-heavy-duty CX35 transmissions requiring GM DEXRON III (H) fluids.
