Castrol Transmax Offroad 10W is a transmission lubricant using highly refined mineral oil, designed for use in powershift transmissions, final drives and wet-brake systems in off-highway equipment — earthmoving machinery, mining equipment and other heavy-duty off-road applications.
The SAE 10W single-grade viscosity is the lighter powershift transmission viscosity specified by Caterpillar for cold-climate or cool-ambient powershift operation. The product is positioned within the Caterpillar TO-4 powershift transmission fluid class — the off-highway powershift specification covering powershift transmissions, final drives and wet brakes.
Approvals and performance levels include Caterpillar TO-4.
The Castrol Transmax Offroad range covers SAE 10W, 30W and 50W in the Caterpillar TO-4 class.
This drum format is suited to workshop bulk supply, fleet service and high-throughput dispensing via a workshop pump or filtration cart. Store the drum on its side in a bunded area, with the bung uppermost to limit moisture and contamination ingress around the fitting.

A. Castrol Transmax Offroad 10W is designed for powershift transmissions, final drives and wet-brake systems in off-highway equipment — earthmoving machinery, mining equipment and other heavy-duty off-road applications.
A. A powershift transmission is a heavy-duty transmission used in off-highway equipment (loaders, dozers, dump trucks) that allows gear changes under full load without disengaging a clutch — using internal hydraulically actuated wet clutches. Powershift transmissions require a specific transmission fluid (typically Caterpillar TO-4 class) with the right friction characteristics for the wet clutches.
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.
A. Castrol Transmax Offroad 10W meets Caterpillar TO-4.
A. Caterpillar TO-4 is Caterpillar's specification for powershift transmission, final drive and wet-brake fluids used in off-highway equipment. The TO-4 specification covers the friction characteristics required for powershift wet clutches and the EP performance required for the final drive in Caterpillar (and many other OEM) off-highway machines.
A. Caterpillar TO-4 powershift fluids are typically supplied as single-grade SAE 10W, 30W or 50W — the absence of viscosity-index improvers gives the friction stability required for powershift wet-clutch operation. SAE 10W (this product) is the cold-climate or cool-ambient grade.
A. Both are Castrol Transmax Offroad Caterpillar TO-4 powershift transmission fluids. The 10W is the lighter single-grade for cold-climate or cool-ambient powershift operation. The 30W is the heavier single-grade for general powershift service in warm conditions.
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.
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.
