AUTOMATIC TRANSMISSION FLUIDS

Automatic Transmission Fluids

Automatic transmission fluids

The commercial vehicle engine technology has become more demanding and more complex following the big trends on emission legislation, fuel economy and extended oil drains. As a consequence, modern automatic transmissions have also become more complex trying to meet those vehicle needs.

 

In response to that, Castrol has designed a range of automatic transmission fluids that can help the vehicle’s driveline perform at its best. Our product range includes fully synthetic and advanced mineral products which have been designed to offer enhanced protection and help prolong component life.


 Always consult your vehicle handbook to make sure you find the correct fluid for your transmission.

ATF DEX III

Castrol atf dex III

Castrol ATF Dex III is an automatic transmission and power steering fluid for use in GM automatic transmissions pre 2005 and in many automatic transmissions in a range of makes and models where Dexron (II or III) or Mercon performance is required.

 

Application

 

It is fully compatible with earlier Dexron and Mercon type fluids and maybe used for topping up or completely replacing it.

 

Castrol ATF Dex III is dyed red to distinguish it from engine oils should leakage occur.

 

Features & benefits

 

  • Enhanced high temperature performance giving improved and more durable shift feel on gear changes.
  • Increased resistance to oil oxidation and degradation. Increased clutch band and clutch pack capacity.
  • Improved protection of copper and bronze components. Improved low temperature fluidity compared to Dexron IID, Dexron and type Suffix A fluids.
  • Longer transmission component service life especially in high load applications.
  • Enhanced life of copper alloy based components and improved fluid service.

 

Specifications

 

  • Dexron® III H, IID and II.
  • Holden HN 2126.
  • Mazda M III Fluid.
  • Ford Mercon IV.
  • Allison C4.
  • Ford M2C-138CJ.
  • General Motors Type A Suffix A.

For car and commercial vehicle applications.

 

An automatic transmission fluid specifically designed to meet the requirements of Volvo Trucks 97341, Allison TES 389, superseded General Motors DEXRON® III H, Ford MERCON® and Allison C4 specifications. Suitable for use in GM automatic transmissions pre 2005 and in many automatic transmissions where DEXRON® (II or III) or Mercon performance is required. It is also suitable for many earlier model Japanese vehicles where DEXRON® type fluids are recommended. It is recommended for other transmissions where DEXRON® and DEXRON® II fluids are specified except Mercedes-Benz, ZF, BMW, Voith and Renk.

 

Features & benefits

 

  • Enhanced friction durability prolongs transmission life and promotes smooth shifting.
  • Increased resistance to oil oxidation and degradation.
  • Increased clutch band and clutch pack capacity.
  • Improved protection of copper and bronze components.

Castrol transmax z

Castrol transmax z

Fully synthetic DEXRON® III type ATF with proven outstanding performance in high temperature and heavy duty applications.

 

Excellent for competition use, towing or high performance usage. Suitable for use where DEXRON® fluids are recommended, except where Castrol Transmax Dex VI is specified.

 

Features & benefits

 

  • Excellent resistance to oxidation thus assisting in prolonging the life of the lubricant
  • Extended oil drain potential resulting in lower operating costs,
  • Enhanced protection against deposits to extend transmission life,
  • Temperature reduction in severe conditions improves transmission and oil service life, and assists in reducing fuel consumption and emissions,
  • Optimised frictional characteristics to provide smoother gear changes and better protection against wear,
  • Outstanding cold flow properties materially assisting in reducing wear at start-up,
  • Proven performance in drag racing (e.g., Lenco drag racing transmission in Pro Stock).
  • Low foam – stable gear shift performance when transmission is hot,
  • Compatible with mineral/conventional automatic transmission fluids,
  • Better control of deposits – cleaner transmission – longer transmission life.

Castrol transmax offroad

Castrol transmax offroad

(Replaces tfc)

 

A range of transmission fluids specifically formulated to satisfy the requirements of Caterpillar TO-4. Suitable for  Komatsu Micro Clutch transmission fluid requirements. For use in powershift or manual transmissions in many types of earthmoving equipment. 

 

Although the SAE 10W, 30 satisfy Allison C4 requirements, most modern Allison transmissions recommend Castrol Transynd or Dexron® type ATF’s, TES-389.

 

Features & benefits

 

  • Transmax Offroad 30 prime recommendation for Cat. Powershift transmissions.T
  • ransmax Offroad 50 recommended for Cat. Final drives requiring TO-4.
  • Multifunctional in that Transmax Offroad 50 is recommended for most heavy truck manual transmissions where either SAE 50 engine oil or GL-1, 2 or 3 (straight SAE90 is specified).
  • Transmax Offroad series also approved against ZF TE-ML 03, 04, 06, and 14 in the appropriate viscosity grade.
  • Suitable for Komatsu equipment.

 

Specification / technical data

 

Meets or exceeds the requirements of:

  • Transmax Offroad 10: SAE 10W-20, 80W
  • Transmax Offroad 30: SAE 30, 85W
  • Transmax Offroad 50: SAE 50, 85W-90
  • Allison C4, SAE 10W, 30 only, off road
