Case IH Hy-Tran Equivalents: MAT 3505 & MS-1209 Alternatives

VISCOSITY ULTRACTION Original Transmission Hydraulic Fluid

VISCOSITY ULTRACTION Original THF SS is an aftermarket semi-synthetic transmission hydraulic fluid that meets CNH MAT 3540. This makes it compatible with modern Case IH and New Holland agricultural and construction equipment, including CVT-equipped machines. 

The zinc-free formulation is designed for wet brakes, transmissions, final drives, and hydraulic systems sharing a common reservoir.

The viscosity characteristics sit at 9.1 mm²/s at 100°C and 57.0 mm²/s at 40°C, with a viscosity index of 140. The pour point of -43°C provides excellent cold-weather performance, while the Brookfield viscosity of 3,700 cP at -20°C confirms superior low-temperature pumpability. 

The semi-synthetic base oil formulation offers better thermal stability and oxidation resistance than conventional mineral oils.

VISCOSITY emphasizes the fluid’s water tolerance, which addresses a common problem in off-road equipment where water contamination can cause hydraulic system degradation and unplanned downtime. The friction modifiers target brake noise suppression and smooth clutch engagement, both critical for equipment operating under heavy loads in severe conditions.

MAT 3540 is the latest CNH specification, replacing earlier standards like MAT 3505. Since MAT 3540 is backward compatible with MAT 3505 and MS-1209, this fluid works in both legacy and current Case IH equipment. While the fluids listed above provide gear protection, it is important to distinguish GL-4 vs GL-5 gear oils, as the latter often contains sulfur-phosphorus additives
that can damage the yellow metals found in tractor transmissions.

Equipment Using MAT 3505 and MS-1209

Modern equipment built after 2012, including the Case IH Steiger, Quadtrac, and Magnum series, has shifted to MAT 3540 as the current engineering specification. MAT 3540 maintains backward compatibility with MAT 3505 and MS-1209, so fluids meeting the newest standard work in older equipment. Always verify the specific capacity and specification in your operator’s manual, as requirements vary by model year and configuration.

High-Horsepower CNH Tractors (MAT 3505)

MAT 3505 is designated for higher-horsepower equipment. Steiger articulated tractors and large-frame Magnum tractors (such as the MX Magnum series) require this specification. New Holland TG tractors also use MAT 3505 because they share transmission designs with the MX Magnum platform.

Mid-Range and Utility Tractors (MS-1209)

MS-1209 covers nearly all generations of Case IH and CASE equipment. Compact models include the Case DX24E and DX55. Utility and row crop tractors like the Case IH 504, 606, and 685 fall under this specification. 

Legacy International Harvester models (766, 806, 966 Hydro, 986, 1066, 1086, 1206, 1256, 1456, and 1466) were originally specified for MS-1209 compatible fluids.

Case IH combines with hydrostatic systems have always called for Hy-Tran. The Case 580 L series 2 backhoe also uses MS-1209 specification fluid. Third-party fluids meeting these specs work in equipment from other manufacturers, including certain John Deere models (4430 and 7720), Branson (2400H), and Kubota tractors.

Oil Capacities

Capacities vary significantly based on frame size and whether the tractor has auxiliary hydraulic tanks. The Case DX24E holds 36 quarts for the combined transmission and hydraulic system. The Case DX55 front differential takes approximately 1.5 quarts for a top-off. 

The Case 580B shuttle system traditionally calls for TCH fluid, though some owners use MS-1209 compatible fluids for maintenance.

The Farmall Cub “Touch Control” hydraulic system requires minimal oil compared to larger tractors, though exact capacity isn’t standardized across all units. For legacy International Harvester models like the 1456 and 1086, technicians often recommend running the reservoir 1 to 2 inches above the full mark on the dipstick (roughly 5 gallons over full). 

This overfill compensates for oil movement when operating on hills or slopes, keeping bearings properly lubricated under angle.

Closing Notes

Choosing an equivalent tractor fluid means managing the chemical environment inside your machine. Legacy tractors like the 1066 were built with heavy iron and wide tolerances that could handle less precise fluids. Modern CVTs operate with surgical precision where even microscopic lacquering from inferior additives can cause sluggish performance or outright failure.

Water management remains the critical issue Case IH owners face. When selecting an aftermarket fluid, prioritize products that explicitly replicate the zinc-free, moisture-suspending chemistry of Hy-Tran. The 1% water tolerance is the difference between moisture dispersed safely throughout the system and water pooling on metal surfaces.

If you’re running equipment still under warranty, stick with OEM Hy-Tran or fluids explicitly approved by Case IH. Once the warranty expires, quality aftermarket fluids meeting the proper CNH specifications will serve you well. As always, maintain reasonable change intervals and monitor for contamination.
