The first extended-range electric Opel, the Ampera was launched in 2011, sharing its technical underpinnings with the Chevrolet Volt. Named Car of the Year 2012, it nonetheless failed to find its audience and was discontinued in 2015. Beneath its compact silhouette lies an unconventional automatic transmission. This practical guide explains how to maintain the Opel gearbox in your Ampera and what to do if something goes wrong.
A unique automatic gearbox
The Ampera is fitted with the Voltec 4ET50 continuously variable automatic gearbox developed by General Motors. No version has a clutch pedal: the selector lever is used only to choose between the alternative drive modes, which greatly reduces the risk of driver error. This architecture sets it clearly apart from a conventional manual transmission; our comparison of the differences between manual and automatic gearboxes explains this operating logic in detail.
Maintaining the Opel Ampera gearbox
Simple everyday checks
Never engage an alternative drive mode — such as reverse or park — until the Ampera has come to a complete stop, as doing so risks damaging the transmission. Also observe the manufacturer's maximum towing weight of two tonnes to avoid overloading the drivetrain.
Gearbox oil changes
Make a habit of checking the oil level using the reservoir dipstick. The level should sit between the two markers; if it falls below the lower mark, a leak is likely and should be addressed without delay. Check the condition of the oil too: blackened fluid is saturated and loses its effectiveness. This fluid lubricates the internal components and dissipates heat, and a lack of it can cause temperatures under the bonnet to rise sharply. Because an automatic gearbox is more sensitive than its manual counterpart, this maintenance task deserves careful attention.
Repairing the gearbox: your options
When a fault occurs, the first step is to have a professional mechanic carry out a diagnosis. Describe any noises, vibrations, power loss or slipping sensations you have noticed. Most faults can be dealt with in the workshop, but severe deterioration may require a complete gearbox replacement. Rather than a new unit with long lead times or an uncertain second-hand part, choose one of our reconditioned gearboxes, available in our reconditioned gearbox catalogue and the Opel gearbox range. For other models, see our advice on the Opel Corsa gearbox or the Opel Insignia gearbox.
Good habits specific to an electrified vehicle
The Ampera stands out for its electrified drivetrain, which changes the driving experience. The absence of gears to change manually is no excuse for heavy-footed driving: smooth, progressive acceleration protects the entire transmission and maximises range. Pay close attention to the vehicle's behaviour during deceleration and report any unusual change to a professional without delay. Respecting the maximum load of two tonnes prevents unnecessary strain on the drivetrain. Finally, keeping a close eye on fluid levels and following the manufacturer's recommended checks will maintain performance — the Ampera being a model that demands rigorous technical upkeep.
Bear in mind too that the Ampera's gearbox, being a bespoke design, is best entrusted to a professional at the first sign of trouble. Early intervention limits the extent of repairs and prevents a lengthy spell off the road.
