Suzuki Celerio: Transmission

Yes. The automated-manual derivatives carry clutch actuation hardware that the plain manual simply does not have, and the two are not interchangeable — say which gearbox the car has when you enquire. With the Celerio that replaced the Alto here in 2015, and the later car that followed it to choose between, transmission is not something we quote off the model name alone.

K10B 1.0 three-cylinder and K10C DualJet 1.0 three-cylinder on the later car. Transmission fitment often follows the engine family rather than the nameplate, so the code on the block is worth reading before you order.

Sometimes, and it is worth knowing where: shares its 1.0 three-cylinder with the Alto and the S-Presso, so donor stock is far deeper than Celerio numbers alone suggest. The Toyota Vitz sold here is also reported to be a rebadged Celerio — worth checking as a donor, but confirm by part number before you buy. Where the hardware is genuinely shared it widens the pool we can search for transmission. We verify the overlap before offering it — we never assume it.

It drives like one, but underneath it is an ordinary manual gearbox with an actuator bolted on to work the clutch and select the gears for you. There is no torque converter, no planetary gearset and no valve body at all, which is why the shifts feel slower and more deliberate than a conventional automatic. The upside is a simpler, lighter unit; the thing to understand is that it is a manual in everything that wears.

Yes, and this catches people out. Because it is a manual gearbox underneath, an AMT car has a clutch disc, a pressure plate and a release bearing exactly as a manual does, and they wear the same way. Stop-start traffic and hill starts are what use them up, since the actuator slips the clutch to get the car moving just as a driver would. A conventional torque-converter automatic has none of those parts, so do not assume an automatic badge means no clutch to replace.

Partly, and the distinction is worth getting right before you buy anything. The casing, gearsets and shafts are largely common, so internal manual components are often a sensible route. The actuator unit that operates the clutch and shifts gears, its associated linkage and the control module are AMT-only and will not be sitting on a manual donor gearbox. It is also worth knowing that the word automatic covers four unrelated gearboxes across the Suzuki range here: this automated manual on the small cars, a four-speed torque-converter automatic on much of the 1.5 range, a continuously variable transmission on the newest models, and a six-speed automatic higher up. They share nothing internally. Use the quote form with your model year and derivative so we quote the right one.
