Q 1. What transmissions is Castrol Transmax ATF DX III Multivehicle designed for?

A. Castrol Transmax ATF DX III Multivehicle is recommended for GM automatic transmissions pre-2005 (Dexron II or III specification) and commercial vehicle automatic transmissions specifying a Dexron-style ATF.

Q 2. What performance class does Castrol Transmax ATF DX III Multivehicle meet?

A. Castrol Transmax ATF DX III Multivehicle is positioned to the General Motors Dexron II and III automatic transmission fluid specifications.

Q 3. What is an OEM Specification?

A. An OEM Specification is the lubricant requirement set by a vehicle or equipment manufacturer (e.g., MB 228.3, VW 504.00). When an oil lists the code, the oil manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a lubricant engineered for your machine.

Q 4. What is an OEM Approval?

A. An OEM Approval means the oil has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 228.3). An Approval confirms the oil is recognised by the equipment manufacturer for service use in their machines.

Q 5. What OEM manufacturer approvals does Castrol Transmax ATF DX III Multivehicle carry?

A. Castrol Transmax ATF DX III Multivehicle carries MAN M339 L, V and Z; ZF TE-ML 04D; and Allison C-4.

Q 6. Can Castrol Transmax ATF DX III Multivehicle be used in modern Dexron VI transmissions?

A. Dexron VI is a different specification superseding Dexron III in modern GM passenger car service. Castrol Transmax ATF DX III Multivehicle is the correct selection only where the equipment manufacturer specifies Dexron II, III or equivalent — not where Dexron VI is specified. Always check the vehicle handbook.

Q 7. Is Castrol Transmax ATF DX III Multivehicle suitable for commercial vehicle automatic transmissions?

A. Yes, Castrol Transmax ATF DX III Multivehicle carries approvals for MAN M339 L/V/Z, ZF TE-ML 04D and Allison C-4 — making it suitable for specified commercial vehicle and bus automatic transmissions.

Q 8. What is an API/ACEA classification?

A. API and ACEA are the universal lubricant performance standards every reputable oil meets. They are your baseline check — match the code your handbook specifies (e.g., API CI-4 or ACEA E7 for heavy-duty diesel) and the oil is technically suitable for your machine. Every oil on our site lists its API and ACEA classifications.
