Same ATF+4 specification as the quart bottle, supplied in a gallon so a full fluid and filter service does not mean juggling four containers. ATF+4 is not interchangeable with Dexron or Mercon style fluids, and the friction modifiers in it are what the shift calibration was developed around.

Fluid Specifications:

• Meets Chrysler Material Standard MS-9602-F.
• ATF+4 specification fluid for select Dodge and Ram automatic transmissions.
• Fully synthetic with the factory friction modifier package.
• 1 gallon, 128 oz. bottle.
• Do not substitute a universal or multi-vehicle ATF where ATF+4 is specified.
