VALVOLINE VV325 5 gal Drive Train fluid
VALVOLINE VV325 is a 5 gal bucket of Drive Train 30W transmission fluid designed for powershift transmissions. It meets Caterpillar TO-2 and Allison C-4 specifications for heavy-duty equipment. The amber fluid carries a viscosity index of 102 for consistent flow.
Sustained load viscosity stability
The fluid maintains its SAE 30 grade under continuous powershift operation where temperatures climb steadily. A viscosity index of 102 resists thinning so the transmission keeps proper line pressure through long shifts. Caterpillar TO-4 and Allison C-4 approvals confirm the additive package holds up in extended duty cycles.
Bucket handling and common issues
The 5 gal bucket pours directly into fill ports but its weight makes one-handed pouring awkward on tall reservoirs. A separate spout or pump reduces spills on hot components. Users sometimes confuse this 30W grade with lighter hydraulic oils; verify the transmission calls for SAE 30 before filling.

Questions about this item
How much heat does the 30W fluid handle during all-day powershift operation?
The fluid carries a viscosity index of 102 and meets Caterpillar TO-2 plus Allison C-4 standards, so it resists thinning under sustained high-temperature loads in powershift transmissions.
What transmission type must I already have for this 5 gal bucket to be the right fill?
It is formulated for powershift transmissions that call for a SAE 30 grade fluid approved to Caterpillar TO-2 and Allison C-4 specifications.
Will the amber 30W fluid mix safely with older TO-4 fluid already in the system?
The product meets both Caterpillar TO-2 and TO-4 standards, so it is compatible with existing TO-4 fills in powershift transmissions.
