Faw Truck Gearbox Parts: Fix Common Issues & Choose Right
If you own a Faw truck, you know firsthand how important Faw truck gearbox parts are—without them, your truck can’t run right.
I’ve seen so many drivers waste time and money because they brushed off small gearbox issues. Before they knew it, those little problems turned into big, expensive breakdowns.
This guide isn’t just generic fluff—it’s the real deal: practical fixes for the issues you actually run into with your Faw truck’s gearbox, plus simple tips to pick the right parts and skip the costly mistakes.
A lot of other guides just list parts and call it a day—but that’s not what you need. We’re all about solving real problems here.
If your gears are stuck, you’ve got a leak, or parts are wearing out too fast, this resource will help you fix it quickly and keep your FAW truck rolling. And the best part?
We’ll show you how to pick the right FAW truck gearbox parts without guessing—we’ve worked with tons of FAW fleets and individual drivers over the years, so we know what works (and what doesn’t).
Common Faw Truck Gearbox Parts Issues & How to Fix Them
Let me be real—most gearbox problems aren’t random. They usually come from either worn-out Faw truck gearbox parts or slacking on maintenance.
I’ve been doing this for 8 years now, and I can tell you: if you ignore small warning signs—like struggling to shift gears or weird noises from the box—you’re gonna end up with way costlier repairs later.
Below, I’ll break down the most common issues, why they happen, and how to fix ’em yourself with basic tools (no fancy equipment needed).
1. Low/High Gear Failure (Most Common Issue)
We get a lot of calls from drivers who suddenly lose low or high gear—way more than you might think.
This issue pops up most often on Faw trucks with 12JS160TA or CA10TA gearboxes, the ones with that main-auxiliary box setup. And here’s the good news: it’s almost never a full gearbox replacement.
Usually, it’s just a faulty shift cylinder, worn-out O-rings, or a clogged pressure relief valve causing the problem.
Fixing it is simpler than you’d think. First, check your truck’s air pressure—low pressure is a common culprit for gear shift issues. Then, while the truck’s in neutral, toggle that high/low gear switch and listen for a click from the shift cylinder.
If you don’t hear that click, check the air lines for leaks or clogs. If the lines look good, the shift cylinder’s O-rings are probably worn out.
Replace those with genuine Faw truck gearbox parts—they’ll fit perfectly. Need the right O-rings for your model? Our product system page has you covered.
2. Gearbox Leaks
Gearbox fluid leaks are another big issue we see all the time—and if you ignore them, they’ll lead to overheating and serious internal damage.
From what I’ve dealt with over the years, most leaks aren’t anything too complicated: usually, it’s a worn-out gasket or loose bolts on the gearbox cover. Sometimes, folks put too much fluid in, and that extra pressure pushes fluid out, causing a leak.
Fixing it’s easy—start by wiping down the gearbox so you can find where the leak’s coming from. If it’s around the cover, just tighten the bolts gently—don’t overdo it, or you’ll crack the cover.
If the gasket’s worn out, swap it for a genuine Faw one; those aftermarket gaskets are usually too thin and won’t hold up long.
Also, check the fluid level and top it off with the Faw-recommended gear oil. Need more detailed tips to find and fix leaks? Head to our support page—we’ve got you covered.
How to Choose the Right Faw Truck Gearbox Parts
Picking the right Faw truck gearbox parts is just as crucial as fixing issues fast—trust me, I’ve seen this kind of thing time and time again.
Over the years, I’ve watched so many drivers waste hundreds of dollars on aftermarket parts that either don’t fit right or break down in just a few months.
To save you that hassle, I’m going to share some simple tips I’ve picked up from working with Faw trucks for years.
First off, let’s get straight to the point: before you buy any parts, you gotta double-check your truck’s model and the type of gearbox it has—don’t cut corners here.
Take Faw’s 12JS160 and CA gearboxes, for example. They might look similar, but their parts aren’t interchangeable at all. A shift cylinder that fits the 12JS160 gearbox won’t work for the CA series—waste of money and time.
Our product brand page lets you search by your truck’s model, so you can grab the exact parts you need right away—no guessing, no running back and forth.
Also, always go for genuine Faw Truck Gearbox Parts instead of aftermarket ones. These genuine parts are made to Faw’s strict standards—they last way longer and fit your truck’s components perfectly, no guesswork needed.
Aftermarket parts might seem cheaper at first, but they wear out fast (usually 6 to 12 months) and end up costing you more in repairs down the line.

Pro Tips to Extend the Life of Your Faw Truck Gearbox Parts
Fixed your gearbox and chose the right components for it? This is not enough—maintaining FAW Truck Gearbox Parts means doing simple routine work. After years spent repairing these trucks, I can assure you that these recommendations will help you double their service life without spending any additional money on endless repair work.
First, make sure that the gearbox fluid is changed periodically – 50 thousand miles would be a good standard. However, don’t forget about the type of this liquid – it should be exactly the type recommended by the manufacturer.
Otherwise, its wear will accelerate rapidly, damaging all gearbox parts within a short time period. The problem is that many truck owners skip changing this fluid, which is a rather absurd idea.
Also, don’t rush when shifting gears—especially when the truck’s moving fast. Forcing the gearbox into a lower or higher gear at high speed puts way too much stress on your FAW truck gearbox parts, and they’ll wear out way sooner than they should.
Take your time, shift slowly, and always come to a full stop before putting it in reverse. Trust me, this small step saves a lot of trouble later.
One more thing—check your gearbox’s mounting bolts every now and then. If they’re loose, they’ll cause vibration, and over time, that vibration will damage the gearbox housing and the internal parts.
Just tighten any loose bolts, and if any are worn out or stripped, replace them with genuine FAW parts—aftermarket ones won’t hold up long.
Final Thoughts
FAW truck gearbox parts are make-or-break for your truck—skip taking care of them, and you’ll be stranded on the side of the road before you know it.
Let’s be real: most gearbox headaches—whether it’s losing low/high gear or fluid leaks—aren’t that hard to fix. All you need is the right parts and a little know-how.
Grab genuine parts, fix small issues fast, and stick to basic maintenance, and your FAW truck will keep rolling smooth, with no costly downtime to stress about.
