The gearbox of the Chevrolet Colorado is put through its paces on this compact pick-up, which shares its underpinnings with the GMC Canyon. Versatile and well suited to professional use, the Colorado wins fans with its load capacity and spacious cabin. On sale since 2003 and named Truck of the Year by Motor Trend in 2023, it remains a reliable vehicle, though certain components can deteriorate over time. EDEN BOITES explains how to get your gearbox repaired effectively.
What are the technical specifications of the Chevrolet Colorado?
The third generation currently offers only petrol engines: the 2.7-litre L2R and L3B Turbo units from General Motors, paired with the 8-speed 8L80 automatic gearbox. Earlier generations offered a wider choice, including a 2.8-litre turbodiesel producing 180 hp and up to a 3.6-litre V6 with 305 hp, available with either a 6-speed manual or 6-speed automatic gearbox. Drive is either rear-wheel or four-wheel, the latter adding a transfer case.
How do you get your gearbox repaired effectively?
Signs of a problem
- Slipping on start-off, difficulty disengaging the clutch, vibrations in neutral: worn flywheel or clutch.
- Resistance when changing gear: incorrectly adjusted gear cables; crunching noises point to worn synchromesh rings.
- Whining as the revs rise: deteriorated bearings.
- Noises under acceleration or engine braking: differential failure.
Why gearbox oil changes matter
Gearbox oil lubricates the transmission and dissipates heat, but it picks up contaminants over time. For automatics, change it every two years or 60,000 km; for manuals, every five years or 250,000 km. Our guide on how a gearbox works is there to help.
