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 says Donax TX offers a high-performance optimized additive package that allows for extended drain intervals.
Shell Donax TX fluid has a drain period of 100,000 miles in regular service, according to the company, and 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 says it 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 if a Shell Donax TX lubricant failure is found to be directly responsible for equipment damage under proper operating conditions, Shell will repair the equipment.
According to the company, 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 6-speed CX31 transmissions; and 8-speed super-heavy-duty CX35 transmissions requiring GM Dexron III (H) fluids.
