Parts & Accessories Spare parts Experiencing jerking in the gearbox? Strong jolts? Or delayed shifting? So why does the problem return even after changing the oil or performing a software update? The question we always get asked... "Is the gearbox broken? Or is the problem simpler than that?" 📌 The reality that many don't notice: Not every gearbox problem means a complete overhaul. In Changan cars, the fault is often due to: Excessive heat affecting the gearbox oil Delayed oil change or using the wrong type Weakness in the Valve Body Outdated software that doesn't match your usage And the problem? If it's temporarily fixed... it comes back after a while, and maybe worse. So how do we fix it? We start with a thorough inspection of the entire gearbox: Computer scan + gearbox pressure reading Actual road test Identifying the fault: electrical, mechanical, or oil-related only Then we work on the right solution: Changing to original oil with the correct specifications Updated software Repairing or replacing the Valve Body if needed Or a complete overhaul (if it's proven to be the only solution) 📌 We work inside the workshop, not random replacements 📌 Original or certified parts 📌 Inspection before and after so you can see for yourself Duration of work? From 1 to 5 days depending on the condition (not all gearboxes need an overhaul) Because every case is different, but we give you a clear diagnosis before any step. And the cost includes disassembly and reassembly if needed. In conclusion: A radical solution to the gearbox problem... not a temporary patch. And if the problem is not solved? You are not obligated to pay at all. Our goal is to actually fix the fault before anything else.
