HOUSTON, Tex. — Shell Lubricants has launched a new heavy-duty semi-synthetic automatic transmission fluid.
The company says its new Donax TX offers improved performance and 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.”
Donax TX has a drain interval of 100,000 miles during regular service and 50,000 miles in severe service applications. Although the new oil doesn’t have formal Allison TES-295 approval, officials insist the fluid is suitable for use and will not harm Allison automatic transmissions.
