An iconic microvan launched in 1960, the Daihatsu Hijet embodies ingenuity and practicality in a compact format. Its name — a blend of "High" and "Jet" — sums up the manufacturer's ambition: to deliver agile, efficient driving even in the tightest of spaces. A light commercial vehicle prized for its versatility, economical engine and manoeuvrability, the Hijet has earned a reputation for reliability. That said, its gearbox can show signs of wear over time. EDEN BOITES explains how to spot the warning signs and how to repair or replace the gearbox on your Daihatsu Hijet.
How to spot gearbox problems on your Daihatsu Hijet
To catch a developing gearbox issue on your Hijet early, keep an eye out for the most telling warning signs:
- difficulty changing gear: juddering, jolts or hesitation when engaging gears;
- unusual noises while driving, such as grinding or abnormal cracking sounds;
- possible transmission fluid leaks, betrayed by stains beneath the vehicle after it has been parked for a while;
- engine overheating, which can sometimes be a consequence of a gearbox fault;
- the transmission warning light illuminating on the dashboard — the clearest sign of a malfunction.
If you notice any of these signs, have your vehicle checked by a professional to avoid making the problem worse and causing further damage to the gearbox. Depending on whether your Hijet has a manual or automatic transmission, maintenance and diagnosis will differ slightly; our guide on the differences between manual and automatic gearboxes will help you get a clearer picture.
Repairing the Daihatsu Hijet gearbox
Once a specialist has identified the fault, repair work can begin. This starts with carefully dismantling each component of the gearbox to pinpoint the exact cause of the problem. A thorough, complete fluid drain follows, along with repair of any leaks or localised defects. It is also important to inspect the surrounding areas for any underlying issues. Reassembly is then carried out with care, in strict accordance with the manufacturer's instructions, to avoid damaging any components.
This work requires in-depth mechanical knowledge and genuine hands-on experience. If you do not have the necessary skills, it is far better to entrust the job to a professional than to risk making the problem worse.
Replacing the Daihatsu Hijet gearbox
When the Hijet only requires minor repairs — such as replacing internal components — refurbishing the transmission system remains a viable option. However, in the face of significant internal damage or severe wear accumulated over time, a full gearbox replacement is the right course of action to ensure the vehicle's longevity and optimal performance. In this case, an exchange gearbox is a reliable solution: every unit is stripped down, carefully tested and thoroughly cleaned before being rebuilt by our team, whether it is a manual or automatic gearbox. Other Daihatsu models also have dedicated guides: discover our advice on the Daihatsu Charade gearbox and the Daihatsu Trevis gearbox.
Frequently asked questions
My Hijet gearbox is making a cracking noise — is it serious?
A recurring cracking noise often indicates internal wear or insufficient lubrication. It is best to have the gearbox diagnosed promptly to prevent the wear from progressing further.
Is a transmission fluid leak urgent?
Yes. A leak leads to inadequate lubrication and accelerates wear on the internal components. Getting it checked without delay will limit the damage.
Can I repair the Hijet gearbox myself?
It is possible with the right tools and expertise, but the job is complex. If in doubt, having a professional carry out the work ensures a safe result.
Do you offer gearboxes for both manual and automatic Hijet models?
Yes, our range covers both transmission types. Accurately identifying your reference ensures the part is compatible with your vehicle.
