TRANSflo TO-4 is a premium transmission fluid specially formulated to meet the exacting requirements of Caterpillar's latest performance specification, TO-4 (Transmission Oil, level 4).
TRANSflo TO-4 is a high performance transmission oil using high-quality paraffinic base stocks with the very latest additive technology specially developed for use in Caterpillar drive trains. It satisfies the tough service needs of powershift transmissions, differentials and final drives. It is available in three SAE* grades that can be matched to any climatic conditions.
Caterpillar recommends TO-4 type fluids in all new and rebuilt drive-train components. Irving TRANSflo TO-4 can be used wherever Caterpillar recommends its ownbrand TDTO "or equivalent".
