New Holland 134D (often listed as M2C134D) is a universal tractor transmission fluid that works as a multipurpose lubricant across hydraulic systems, transmissions, differentials, wet brakes, power steering, and PTO clutches. You’ll find it specified for Ford and New Holland tractors ranging from vintage N-series models through newer compact units like the T1510.
New Holland WB NWH 410B is the branded designation for Ambra Multi-G 134 Fluid, which is essentially New Holland’s version of the Ford M2C-134D spec. For years, NH-410B (Multi-G 134) was the standard recommendation for everything from vintage N-series tractors through modern equipment. The 134D specification has since been superseded by CNH MAT 3540 (Ultraction), though 134D-spec fluids remain widely used in older equipment.
Because 134D cross-references with many industry standards, owners of mixed fleets often look for a single fluid that also serves as a John Deere Hy-Gard J20C and J20D Equivalent to simplify maintenance.
The OEM fluid isn’t always easy to source locally, and price can be a factor when you’re filling large hydraulic systems. That’s why finding a reliable New Holland 134D equivalent matters. Let’s look at which aftermarket options actually meet the spec.

Tractors that Specify New Holland 134D
New Holland 134D (and its equivalent specifications like NH-410B) covers a wide range of Ford and New Holland equipment, from vintage tractors through modern compact models.
The N-series tractors (9N, 2N, 8N, and NAA Jubilee) originally specified 90-weight mineral oil, but 134D is now the standard recommendation from New Holland. The Hundred series (600, 700, 800, 850, 851, 860, 900) and Thousand series (2000D, 3000, 4000, 5000D, 6000, 7700) use 134D for hydraulics and common sumps. Later Ford models in the 10 and SU series (2310, 2600, 2610, 3600, 3610, 4100, 4110, 4600, 4610, 4600SU) specify Ford 134 or equivalent. Modern equipment includes the New Holland T1510, T4.105, TN 95FA, and Boomer series, though Boomer models often use newer synthetic versions that supersede 134D.
Industrial and construction equipment like the Ford 555A, 555C, 545D backhoes, and utility models (5030, 4830) require 134D for wet brakes and torque converters.
Because 134D cross-references with John Deere J20C and Kubota UDT specifications, it’s sometimes used in Mahindra tractors (TC29D, E350DI), Kubota models (M8540), and other equipment like Volvo EC60E excavators.
Owners of vintage tractors like the 8N sometimes stick with 90-weight mineral oil if their systems leak, since 134D’s thinner viscosity exposes worn seals. For cold-weather operation, 134D is preferred because it flows immediately at startup.
New Holland 134D is the current standard recommendation from dealers and official manuals for vintage Ford tractors, including the N-series (9N, 2N, 8N, NAA Jubilee) and Hundred series models. The 134D specification itself has been superseded multiple times, with CNH MAT 3540 (Ultraction) now being the top-tier specification. Major manufacturers like Mobil Delvac, Valvoline UniTrac (VV813), and Shell Rotella still produce fluids meeting or exceeding the 134D spec.
Many owners of vintage equipment prefer the original 1939 specification of 90-weight GL-1 mineral oil for practical reasons. The 134D fluid runs significantly thinner (similar to 20-weight oil), which can leak through worn seals that heavier 90-weight oil would seal. In summer months or high-heat conditions, the thinner 134D can become too light for worn hydraulic pumps, causing the hydraulic lift to slow down. The heavier 90-weight oil maintains better performance in these worn systems.
The trade-off comes in winter operation. The 90-weight oil stiffens in freezing weather, leaving hydraulics moving slowly until the system warms up. The 134D stays fluid enough for immediate hydraulic response at startup, which is why it’s preferred for cold-weather operation.
If you choose heavier oil for a vintage tractor, it must be GL-1 mineral oil, not modern 80/90-weight GL-5 gear oil. GL-5 oils contain high levels of sulfur and phosphorus additives that attack the copper and brass components found in vintage hydraulic pumps and synchronizers. GL-1 mineral oil is safe for these yellow metals.
Closing Notes
The original Ford M2C-134D spec was written for a world of simpler gear geometries. Modern equivalents, specifically those meeting the MAT 3540 standard, use much more stable polymer thickeners. In a hardworking PTO or a differential under high load, the original 134D fluid shears (thins out permanently) much faster than a modern semi-synthetic equivalent.
This creates a compatibility paradox: a modern fluid like VISCOSITY Ultraction is technically compatible. But because it maintains its thickness under pressure better than the original fluid, it can change the feel of your tractor’s wet brakes and clutches. If your brakes feel grabby after a fluid change, it isn’t necessarily a failure of the oil. It’s often because the new fluid is providing a higher film strength than the worn mechanical surfaces were accustomed to.
If your gears have decades of play, a high-shear-stable modern fluid is actually your best defense against further metal-to-metal contact. For equipment that sees heavy PTO work or long hours under load, the superior shear stability of fluids like TRIAX AGRA UTTO Supreme (VI 176) or MAG 1 (VI 152) will maintain consistent hydraulic response longer than conventional mineral-based 134D fluids.
As always, check your equipment manual for the recommended service intervals and fluid capacity.
