The gearbox of the Chevrolet HHR plays a central role in this retro-styled compact estate, inspired by the manufacturer's SUVs from the late 1940s. Sold between 2005 and 2012, the HHR shifted over half a million units. Like any vehicle, its internal components can deteriorate over time, and the transmission is no exception. This EDEN BOITES guide explains how to manage its repair effectively.
Under the Bonnet of the Chevrolet HHR
The HHR was produced in a single generation. Three engines were offered, all petrol, inline four-cylinder, with engine capacities ranging from 2.0 to 2.4 litres. These Ecotec units developed by General Motors produce between 155 and 260 bhp. Drive is sent to the front wheels across the entire range. Drivers had the choice of three gearboxes: two 5-speed manuals (the Saab F35 and the Getrag F23) and a GM 4-speed automatic.
Good Daily Habits to Keep Your Gearbox in Shape
Good Driving Habits
With an automatic gearbox, never change gear until the vehicle has come to a complete stop, and do not use the P position as an engine brake. With a manual gearbox, which is more vulnerable to driver error:
- Do not rest your hand on the gear lever.
- Select neutral during brief stops.
- Guide the lever smoothly and depress the clutch pedal fully.
Warning Signs
Take any sign of wear seriously and describe it precisely to your mechanic:
- Unusual noises (squealing, grinding, clunking) and when they occur.
- Excessive vibrations inside the cabin.
- Stiffness in the clutch pedal or gear lever.
- A gear jumping out or refusing to engage.
- Loss of performance on an automatic.
- Oil leaks beneath the vehicle.

A Professional Diagnosis for a Stress-Free Repair
Some repairs are straightforward: low transmission fluid or a worn component that needs regular replacement, such as gears. In more advanced cases, the mechanic will need to replace the entire gearbox. Sourcing a second-hand unit independently remains a gamble, as its condition is unknown before fitting, while a new gearbox means long lead times and a high price tag.
