Genuine Toyota R151 Gearbox

Overview of the Genuine R151 Gearbox

The R151 Gearbox is one of Toyota’s most trusted manual transmissions, known for its strength, reliability and ability to handle upgraded power in popular 4×4 builds. This genuine unit is designed for owners who want factory level performance rather than reconditioned alternatives. Whether your vehicle is used for touring, towing or weekender trips, the R151 delivers smooth shifting, confident torque transfer and long service life. At Hassard Industries, we prioritise genuine drivetrain components for customers seeking durability without compromise, and this gearbox represents the highest level of OE quality available for Toyota diesel platforms.

Why Choose a Genuine R151 Gearbox

The R151 has a long reputation across models, especially when paired with engines like the 1HZ . Unlike many older R series transmissions that have seen decades of wear, a genuine replacement restores proper gear engagement, synchro performance and noise levels. This is essential for vehicles carrying heavy loads or running larger tyres. Toyota’s build quality offers tighter tolerances, smoother bearings and correct clearances, which means better heat management and improved gearbox longevity. Choosing a genuine unit reduces the likelihood of future rebuild costs, saves downtime and ensures fitment matches factory specifications.

Fitment Compatibility

This R151 Gearbox suits a wide range of Toyota 4×4 models that originally came with the R151 transmission. Common applications include:

• HZJ105

What You Receive

Performance Notes for Customers

The R151 is known for strong torque handling. It pairs extremely well with quality clutch packages, especially NPC Performance Clutches that we commonly supply and install in-house. When replacing or upgrading your gearbox, we recommend inspecting your rear main seal, spigot bearing, clutch, engine mounts and transfer case oil levels to get the best result from your new transmission.
