Tremec T-56 Magnum 3rd Gear – 1.46 Ratio (Wide Ratio)

OEM Tremec 1.46 ratio 3rd gear for T-56 Magnum wide-ratio transmissions. Direct replacement for GM and Ford applications using TUET11011 and TUET11012 gearsets.

If you’re rebuilding or repairing a T-56 Magnum wide-ratio transmission, this is the exact 3rd gear Tremec designed it with—not a substitute, not a workaround, not a gamble.

The Tremec TUEE7581 is the 1.46 ratio 3rd gear used in wide-ratio Magnum transmissions, including TUET11011 and TUET11012. Whether you’re replacing a damaged gear, refreshing a high-mileage unit, or correcting a failed rebuild, this is the correct OEM solution.

Mixing ratios or using incorrect gears inside a Magnum is one of the fastest ways to ruin shift quality and gear engagement. This gear restores proper spacing, engagement, and durability exactly as Tremec intended.

If you’re already this deep into a Magnum, you don’t “close enough” it. You do it right.

Why OEM Matters Here

The Magnum is a precision gearbox. Gear tooth profile, spacing, and ratio matching all matter. Using the wrong gear—or an aftermarket substitute—can result in:

• Poor shift quality
• Noise
• Accelerated wear
• Premature failure

This gear eliminates all of that by restoring factory geometry and performance.

• Intended for professional rebuilds or experienced transmission builders
• Requires full disassembly of the transmission
• Not a bolt-on external service part

If you’re unsure whether your transmission uses the wide-ratio gearset, contact us before ordering.
