Castrol TFC 400 SERIES

A range of lubricants specially formulated to satisfy the requirements for automatic, powershift or manual transmissions. Recommended in Allison C2, C3 or C4, Caterpillar TO-2 or TO-4, Komatsu Micro clutch, API GL1, 2 & 3 or when CF engine oils are specified. 

The Castrol TFC Series are also suitable for use in hydraulic systems where the appropriate SAE grades are specified. Castrol TFC 450 supersedes CRB 50 and ST 90 in heavy duty truck transmission applications.

Castrol TFC 460 is recommended for use in some Caterpillar final drives, and only in equipment which is involved in continuous operation; this being due to the lengthy start-up procedures specified by Caterpillar when using SAE 60 oils.

The Castrol TFC 400 Series is available in five viscosity variants.

*Allison no longer recommend any C4 fluids for use in any on-highway transmissions.
