DI AGNO SING TO ‑ 4 T Y PE P OW E R SHIF T T R A N SMI S SION PROBL E M S Improper use of an ATF or tractor fluid in power‑shift transmissions will often produce burnt and/ or slipping clutches, inadequate holding capacity for both brakes and clutches, and insufficient wear protection for gears. Caterpillar pioneered the TO‑4 for its off‑highway powershift transmissions. Fluids meeting this specification have been factory fill on all CAT powershift transmissions since 1991. Combined with the anti‑wear properties and added gear protection, a premium TO‑4 fluid maximizes powershift transmission life and operating efficiency. Agricultural vehicles like large tractors also employ powershift transmissions. The friction material of the shifting clutches are selected to function properly with tractor hydraulic fluids, which have a low static coefficient of friction to prevent chatter or squawk in the wet brakes used.
