Transmission Fluid & Automatic Transmission Fluid

Keep your vehicles and equipment running smoothly with transmission fluid from Keller-Heartt. Shop automatic transmission fluid (ATF), CVT fluid, synthetic transmission fluid, and multi-vehicle formulas for automotive, fleet, and commercial applications.

Choose from trusted brands including Truegard, Shell, and Spirax, with options ranging from individual containers and 5-gallon pails to bulk 55-gallon drums.

Find the Right Transmission Fluid for Your Vehicle

Transmission fluid helps lubricate internal transmission components, manage heat, support hydraulic operation, and protect against wear. Using the correct fluid is important because transmission requirements vary significantly between vehicles and equipment.

Keller-Heartt carries transmission fluids for a range of specifications and applications, including Dexron, Mercon, ATF+4, CVT, multi-vehicle, and synthetic transmission fluids.

Always check the vehicle or equipment manufacturer's specifications before selecting a fluid.

Automatic Transmission Fluid (ATF)

Automatic transmission fluid is designed to lubricate, cool, and support the hydraulic functions inside an automatic transmission. Different transmissions require specific ATF formulations, so the required specification should always be verified before use.

Shop Automatic Transmission Fluid

Dexron & Mercon Transmission Fluid

Dexron and Mercon are transmission fluid specifications associated with a wide range of vehicle applications. Keller-Heartt carries products designed to meet different Dexron and Mercon requirements, including options for professional shops and fleet operations.

Shop ATF

CVT Transmission Fluid

Continuously variable transmissions operate differently from traditional automatic transmissions and typically require fluid specifically formulated for CVT applications. Using a fluid that meets the manufacturer's CVT specification is critical for proper operation and protection.

Synthetic Transmission Fluid

Synthetic transmission fluids are formulated for demanding operating conditions and may provide improved performance across a wide temperature range. The appropriate formulation ultimately depends on the specifications required by the transmission manufacturer.

Bulk Transmission Fluid for Shops & Fleets

For automotive repair shops, dealerships, quick-lube operations and commercial fleets, purchasing transmission fluid in larger quantities can make inventory management easier while ensuring commonly used fluids remain available.

Keller-Heartt offers transmission fluids in 5-gallon pails and 55-gallon drums, along with smaller package sizes for lower-volume applications.

Frequently asked questions

Find answers to common questions about our products and services

  • Dexron and Mercon are transmission fluid specifications originally associated with General Motors and Ford applications. Multiple generations of each specification exist, so it's important to match the fluid to the requirements of the specific transmission.

  • You should only use fluid that meets the manufacturer's requirements for the transmission. CVTs commonly require specially formulated CVT fluid and should not automatically be treated as compatible with conventional ATF.

  • Using a fluid that doesn't meet the transmission manufacturer's specifications can affect lubrication, shifting, hydraulic operation, and component protection. Always confirm compatibility before adding or replacing transmission fluid.

  • Transmission fluid service intervals vary by vehicle, transmission type, operating conditions, and manufacturer. Follow the maintenance schedule provided by the vehicle or equipment manufacturer.

  • For shops servicing many vehicles, bulk transmission fluid can reduce reliance on individual containers and provide a centralized supply of commonly used fluids. The right quantity depends on the shop's service volume and the number of different transmission specifications it needs to support.
