Toyota's toughness isn't just limited to the multifaceted pick-up trucks in their lineup. Some of these trucks developed super-specific skills like navigating challenging terrain without breaking a sweat. Enter the FJ Cruiser. This towering off-roader might not share the same skeleton as its pick-up cousin, the Tacoma, but both of these trucks share the same beating heart dispersing power and traction to dominate dunes, crawl through crevasses, and ford raging rivers, all of which are not places you'd want your transmission to give out.

Unlike the utilitarian-based Tacomas, the FJ Cruiser lacks the external support for maintaining transmission fluid temperatures. Both platforms utilize a heat exchanger built into the radiator's cold-side end tank, which manages the automatic transmission

The toughest trucks on the planet are typically sporting a Toyota badge. The Hilux might be the model responsible for Toyota's rugged reputation, but that same DNA runs through the oil passages of the trucks we see on and off the roads here in the States. Specifically, the multifaceted Tacoma has become our crowd favorite, from commuting to the office to hauling you and all of your things across the wilderness.
