Toyota RC60 / RC60F

Toyota's six-speed manual for the body-on-frame vehicles — in the Fortuner and the Innova.

It is the R151's six-speed successor and shares its context: working vehicles, loaded, driven in traffic. Its faults are the faults of load rather than of design, and an enormous number reach very high mileages on nothing but the correct oil.

The recurring complaint is second-gear synchro wear, crunching on a fast cold change and nowhere else. A crunch into every gear is the clutch not releasing, which is hydraulic, outside the gearbox, and much cheaper.

It takes a gear oil to Toyota's specification, not ATF — the opposite of the Aisin AX-15, and the same rule as everywhere in this catalogue: read the plate rather than assume what a manual takes.
