The Chery QQ 372 vs 472 manual transmission question comes up in every workshop that quotes a gearbox swap for these small Chinese city cars. The confusion is understandable: “372” and “472” sound like gearbox model numbers, but they are actually engine codes. The gearbox that sits behind both is the QR512 five-speed manual, and knowing how to tell the 0.8-litre application from the 1.1-litre application is what keeps a wrong unit from landing in your crate. This guide shows you which identifiers to read, what changes between the two engine codes, and the checklist to run before you order.
Why “372” and “472” Are Engine Codes, Not Gearbox Codes
The first step is to stop thinking of 372 and 472 as transmission numbers. SQR372 is the 0.8-litre, three-cylinder engine, and SQR472 is the 1.1-litre, four-cylinder engine. Both are called “Chery QQ” cars and both use the same manual transaxle family, which is why buyers and even some suppliers mix the names up.
When a listing says “gear box for Chery QQ 372 472,” it usually means the same gearbox family is offered for both engine codes. But “same family” is not the same as “identical in every detail.” The bellhousing, input shaft, and final drive can differ between the three-cylinder and four-cylinder builds. That is why the correct way to buy is to name your engine code and let the supplier match the QR512 variant to it, rather than ordering on a model name alone.
On our Manual Transmission for Chery QQ – Models 372/472 page you can see the exact unit we build and supply for these applications, together with the configuration we confirm before shipping.
Three Identifiers That Decide Which Gearbox You Need
Instead of guessing by car name, a workshop can confirm the unit in about ten minutes using three identifiers. Industry service manuals work the same way: the ATSG service manual for the JATCO JF011E transmission, for example, shows that the model number stamped into the transmission case is the master identifier, and that one transmission family can span many different vehicles with application-specific differences. The same logic applies to the QR512.
1. The VIN. Chery vehicles use a 17-character VIN that begins with the world manufacturer identifier “LVV.” Inside the VIN there is a character that describes the transmission type, and the engine type is described as well. Read the full VIN off the plate or the gutter channel on the front of the car, not just the last six digits. A supplier who asks for the full VIN is following the correct process.
2. The engine code. The SQR372 or SQR472 code is stamped on the engine block. Photograph the code and the surrounding area so the letter suffixes (such as SQR472F) are readable. The suffix matters because it can change the intake, exhaust, or emission calibration, and the gearbox ratio set is chosen against the engine’s output.
3. The gearbox case stamp. The QR512 model designation is stamped or etched on the transmission case, usually on a machined boss or near the identification tag. Look for “QR512,” “QR512MHE,” or “QR513MHA.” If the old unit is still in the car, note this number before removal; if the case number is unreadable, the old gearbox label or the vehicle’s build records are the backup.
With these three pieces of information, the QR512 variant is no longer a guess. The JF011E confusion in aftermarket listings shows exactly why this matters: a transmission number alone does not guarantee fitment across models. If a listing claims a JATCO CVT-style number such as JF011E for a manual QQ gearbox, treat it as a red flag and verify before committing.
What Changes Between the 0.8 and 1.1 Applications
The QR512 is a two-shaft, five-speed manual transaxle with synchronizers on all forward gears and an integrated differential, driving the front wheels. The published ratio set for the QR512 QR372/QR472 application includes a final drive near 4.41 and gear ratios such as 3.818 first, 2.158 second, and 0.838 fifth, with a 3.583 reverse. These figures are a useful sanity check: if the ratio plate or the supplier’s spec sheet does not look anything like this, ask why.
What changes between the engine codes is not the basic layout but the matched parts around it. The bellhousing bolt pattern must line up with the three-cylinder or four-cylinder block, and the clutch and input shaft are matched to the engine’s torque. The 1.1-litre four-cylinder pulls differently from the 0.8-litre three-cylinder, so the final drive is selected for that application. There is no safe way to “just swap” a gearbox between a 372 and a 472 car and assume the ratios, bellhousing, and clutch match.
For buyers who manage a mixed fleet, the practical rule is simple: name the engine code, name the drivetrain (the QQ is front-wheel drive), and confirm the bellhousing and input shaft with the supplier before any crate is built. You can compare the full range of manual and automatic transmissions we supply across our catalogue.
New or Remanufactured: What to Ask Before You Commit
Once the right variant is identified, the next decision is new versus remanufactured. A new unit ships with fresh castings and components. A remanufactured unit is built from a used core that has been stripped, machined, and rebuilt to specification. Either can be a good buy; the difference shows up in what the supplier can prove.
Ask for the same three things from every seller. First, the identification record: the engine code, the gearbox case model, and the vehicle year and body type you gave them. Second, a condition statement: for reman units, what was machined and what was replaced, and whether the unit passed a dry test or a bench test. Third, the warranty terms in writing. The TOSEN product listing for this gearbox, for example, states a 12-month warranty and 100% testing, and these are exactly the details a buyer should see in writing before paying.
Core returns follow the same principle. If you are sending the old transaxle back, agree in advance on the condition, the OE or old-part reference number that identifies it, and who pays the freight. A “33030-style” parts-catalogue reference on the old unit or its label is useful evidence of the original application — include a clear photo of it with your inquiry so the supplier can match the remanufacturing spec.

Gearbox Oil, Filters and First Checks Before Fitting
The QR512 is a manual transaxle, so the oil does two jobs: lubricating the gears and carrying the differential. Before fitting a supplied unit, check three things. First, the oil grade and fill level — use the grade called out in the QQ service manual for the QR512, fill through the filler port with the car level, and do not overfill. Second, the seals and the breather: a blocked breather can push oil out of the case at highway speed, so replace the input and output shaft seals if there is any doubt about the age of the used unit. Third, the clutch condition — a worn or dragging clutch is the most common reason a freshly supplied gearbox is blamed for shifting problems it did not cause.
Whether the unit is new or remanufactured, treat the first service as a verification point rather than a formality. Shift through every gear with the engine off, then with the engine running and the car stationary, and listen for gear rollover noise that suggests a mismatched ratio set. If anything sounds wrong, stop and re-check the engine code and case stamp before installation goes further.
Crating, Sea Freight and Receiving a Whole Transaxle
A complete QR512 transaxle is a heavy, machined casting that travels in a wooden crate. The public product listing cites a nominal pack size in the range of 60 by 60 by 60 centimetres with a gross weight around 50 kilograms; the exact crate dimensions and weight are confirmed against your specific unit before shipment, because they change the freight quote.
On arrival, inspect the crate before signing anything. Photograph the crate from all sides, look for impact damage, and open it only after the carrier has noted the condition. Check the case for cracks, the machined faces for rust, and the input shaft for movement. A whole transaxle should arrive with the bellhousing and case face protected; if it does not, that alone tells you how the supplier treats the product.
Frequently Asked Questions
Is the same transmission number, like JF011E or a 33030-style reference, shared across different cars?
Sometimes the same family number covers many vehicles, but that does not make the parts interchangeable. JF011E is a JATCO CVT family, not a Chery QQ manual unit, so a JF011E-style reference on a QQ gearbox listing is a red flag. Always confirm by VIN, engine code, and case stamp rather than trusting a number alone.
How do I tell the 0.8 (372) gearbox from the 1.1 (472) gearbox?
Read the engine code stamped on the block: SQR372 is the 0.8 three-cylinder, SQR472 is the 1.1 four-cylinder. Then check the gearbox case stamp for the QR512 variant and confirm the bellhousing and final drive with the supplier using the full VIN.
Can I fit a remanufactured QR512 instead of a new one?
Yes, if the reman unit carries a documented machining record, a stated condition of the core, and a warranty in writing. Send a clear photo of the old gearbox label or OE reference number so the supplier can match the remanufacturing spec.
What should I check the moment the crate arrives?
Photograph the crate before opening, inspect the case for cracks and corrosion, check the input shaft movement, and note the crate condition in the carrier’s presence before signing the delivery note.
Which oil goes into the QR512 manual transaxle?
Use the grade and fill level stated in the Chery QQ service manual for the QR512. Fill through the filler port with the vehicle level, do not overfill, and confirm the seals and breather are sound before fitting.
