Description
When your tractor starts shifting rough or you notice jerky operation during heavy field work, it’s often a sign that your transmission fluid needs attention. Lucas Sure-shift Semi-synthetic ATF is designed to handle the demanding conditions farm equipment faces—from the slow, steady grind of tillage to the stop-and-go work of loading and unloading.
What You’re Getting
- Semi-synthetic formula that protects better than conventional fluids while costing less than full synthetic
- Superior thermal stability to handle the heat generated during long days in the field
- Enhanced friction modifiers for smoother shifting under load
- Anti-foaming agents that keep the fluid working properly even during aggressive hydraulic operation
- Compatible with most automatic transmission and hydraulic systems on farm equipment
Built for Real Farm Work
This fluid works well in tractors with power-shift transmissions, combine harvesters, and other farm equipment that uses automatic transmission fluid. It’s especially useful for machines that see heavy use during planting and harvest seasons when smooth operation is critical for getting the job done.
Made to Last
Farm equipment puts transmission fluid through the wringer with temperature swings, dust, and heavy loads. This semi-synthetic formula holds up better than conventional ATF, maintaining its protective properties longer between changes and helping extend transmission life.
Good to Know
Always check your operator’s manual for the correct fluid specification before adding or changing transmission fluid. This quart bottle makes it easy to top off fluid levels or keep a spare on hand for field repairs. Store in a cool, dry place and keep the cap tight to prevent contamination.
