The Hyundai Trajet gearbox is fitted to an MPV whose production ended in 2008, yet it remains an endearing and reliable vehicle provided the transmission is properly maintained. A seized gearbox, persistent crunching, or gears that won't stay engaged: like any mechanical component, the gearbox wears over time. Here is everything you need to know to repair the gearbox on your Trajet.
The Trajet's gearbox options
Despite a relatively short production run, the Trajet was offered with two gearboxes: a 5-speed manual and a 4-speed automatic. The engine variants help identify the right unit: the 2.0 CRDi 112 hp is available with either a 5-speed manual or a 4-speed automatic, the 2.0i 136 hp with a 5-speed manual or automatic, and the 2.7i V6 170 hp comes as standard with the 4-speed automatic.
Important: these two gearboxes are not interchangeable. A manual cannot be replaced by an automatic, and vice versa. As Hyundai developed several different transmissions, make sure you choose a unit designed specifically for the Trajet. Note the code stamped on the gearbox casing — this is the reference you will need when placing your order.
Repair options
The same symptom can point to several different faults. Crunching noises may stem from poor lubrication — resolved by an oil change — or from a worn component. Stiff gear changes can be down to lubrication, but also to a slack cable, worn synchromesh rings, or play in the linkage. Gears that won't stay engaged suggest worn synchros, their hubs, or the locking mechanism.
Only a mechanic, after a thorough inspection of all components (input shaft, primary shaft, crown wheel, pinions, locking mechanism), can provide a reliable diagnosis and a quote. If the damage is too advanced, they will recommend replacement; in that case, it is more cost-effective to source the part yourself.
Where to buy a gearbox for your Trajet
Only trust the purchase of a used or exchange gearbox to specialists, and always check the warranty. Browse the product listings, select the gearbox suited to your Trajet, and if no reference matches, request the reconditioning of your own unit: a second life for your transmission, more economical than a new gearbox and with comparable reliability.
To go further, explore our catalogue of exchange gearboxes and the range dedicated to the Hyundai gearbox. Driving a different model from the same brand? Take a look at our guides on the Hyundai Santa Fe gearbox and the Hyundai Terracan gearbox. And if you are unsure which type of transmission to go for, our in-depth article on the differences between manual and automatic gearboxes will help you decide before you buy.
