Transmission Fluids

Coastal DexMerc® ATF is a multi-purpose automatic transmission fluid (ATF) and is recommended as a replacement fluid for automatic transmissions meeting original equipment manufacturer’s (OEM) performance requirements of General Motors, Ford, and other domestic and imported passenger cars, vans and light trucks where Dexron II, Dexron II-E, Dexron III-G, Dexron III, H Revision, Automatic Transmission Fluid, or Ford Mercon fluids are specified. It is also, recommended for Allison TES 389, C-3, C-4 applications, and Caterpillar TO-2 applications. Coastal Automatic Transmission Fluid DexMerc is not for use in transmissions requiring Ford Type F fluid.

Coastal Type F Automatic Transmission Fluid is blended with highly refined base oils and a specially balanced additive package that combine to give outstanding performance in the areas of high temperature oxidation resistance, corrosion and rust protection, and dispersancy and detergency. Coastal Type F Automatic Transmission Fluid meets the requirements of Ford specification M2C33-F and is recommended for use in all Ford passenger car automatic transmissions prior to the 1977 models, as well as many 1977 through 1980 models. Please check the recommendation in the owners manual to determine the correct fluid, as misapplication may cause severe performance problems.

Coastal Type A Automatic Transmission Fluid is blended to provide outstanding performance and is recommended for use in all automatic transmission fluids requiring Type A fluid.

Coastal ATF+4 is the recommended fluid for use in Chrysler group automatic transmissions. It is formulated to meet ATF+4 specification MS-9602, ATF+3 specification MS-7176E, ATF+2, and ATF. It is recommended and licensed for all transmissions that call for ATF+4 fluid.

Coastal Multi-Vehicle Synthetic Blend Automatic Transmission Fluid is a new generation automatic transmission fluid recommended for use in automobile and truck transmissions, power-shift transmissions and other types of service requiring Ford MERCON®V, MERCON®, DEXRON® III-H or Allison C-4 automatic transmission fluid. It is approved for use in Voith Transmissions. Approved for ZF applications TE-ML 03D, 04D, 14B, 16L & 17C. Coastal MULTI-VEHICLE SYNTHETIC BLEND ATF is also recommended for service fill in Mercon, Chrysler, Honda/Acura, Hyundai, Jeep, Mercedes-Benz, Mitsubishi (Diamond SP-II or SP-III), Nissan (Matic D, J or K)/Infiniti, Saturn, Toyota (T-III & T-IV)/Lexus/Scion, VW/Audi, most European vehicles including BMW & Volvo, most Asian vehicles including Daewoo, Isuzu, Kia, Mazda, and Suzuki. Coastal MULTI-VEHICLE SYNTHETIC BLEND ATF is not for use in transmissions requiring Ford Type F, DEXRON® VI, MERCON® SP, LV or in Continuously Variable Transmission (CVT) applications. Always consult your owner’s manual where specific automatic transmission fluids are recommended.

Coastal DEXRON-VI ATF is the latest generation automatic transmission fluid approved by General Motors for use in vehicles with automatic transmissions. This unique fluid is specially formulated to provide twice the service life of DEXRON-III (H) ATF and offers improved performance for new and older transmissions. It is formulated to provide improved oxidation stability, shear stability, friction durability, and wear protection to help meet warranty protection requirements in late model vehicles.


When compared to DEXRON-III (H) ATF, Coastal DEXRON-VI provides the following benefits:

* Extends the life of the transmission
* Improved oxidation and thermal stability
* Enhanced foam control
* Outstanding low temperature performance
* Superior anti-wear protection
* Improved torque transfer


Coastal DEXRON-VI is recommended for all GM vehicles with Hydra-Matic automatic transmissions. It is fully back serviceable for DEXRON-III (H), (G), and IIE applications. Meets GM specification GMN10060. General Motors DEXRON-VI ATF License Number: J-60318 Always consult your owner’s manual for specific recommendations.


Coastal TO-4 DRIVE TRAIN OILS are formulated to meet the stringent performance requirements of the Caterpillar TO-4 specification. These fluids are recommended for equipment where specified TO-4 qualified oils are required in order to maintain the Caterpillar equipment warranty. Coastal TO-4 DRIVE TRAIN OILS are blended to provide superior gear wear protection and excellent thermal stability while maintaining a delicate balance of static and dynamic frictional characteristics with a variety of materials to give smooth transmission power transfer under high horsepower conditions. The balanced additive package provides substantially improved load carrying capacities and durability and reduces brake chatter.

Coastal TO-4 DRIVE TRAIN OILS are recommended for the lubrication of heavyduty equipment in both highway and off-highway service that require a lubricant meeting Caterpillar TO-4, Allison C-4, Komatsu KES 07.868.1, Komatsu Dresser, Komatsu Micro-Clutch, ZF TE-ML 01, 03C, 07F, Eaton Vickers EH-1027C, Temec/TCC, Dana Powershift, or API GL-3 specifications. Coastal TO-4 DRIVE TRAIN OILS provides excellent service in all Caterpillar powershift transmissions, final drives, hydrostatic transmissions, torque converters, hydraulics or any system which specify TO-4 qualified oils. The SAE 10W and SAE 30 grades can be used in all applications requiring and Allison C-4 qualified oils.


• Extends component life
• Excellent gear protection
• Oxidation and thermal stability for long life
• Excellent rust and corrosion protection
• Compatible with crankcase engine oils
• Improved friction and anti-wear performance compared to TO-2 fluids

Coastal TO-4 DRIVE TRAIN OILS do not contain friction modifiers or viscosity index improvers and CANNOT be used in farm tractors, and are not designed to be used in engine crankcases.
