Indicative ranges by model and transmission. Actual quotes depend on kilometres, condition, and used vs reconditioned — and on the 722.9 whether the valve body / conductor plate is included.

Condition & warranty
The same Mercedes gearbox comes three ways in South Africa. Here's how they compare on price, warranty and what you get — so you can tell suppliers which to quote.
Tested second-hand box removed from a low-mileage donor vehicle.
Your old core is surrendered; the unit is stripped, rebuilt and tested.
A brand-new unit — aftermarket or genuine OEM-grade.
Not sure which to pick? Send your VIN and ask suppliers to quote all three — you compare price and warranty side by side.
Mercedes's rear-wheel-drive cars run torque-converter 7G / 9G-Tronic autos; the small front-wheel-drive A/B/CLA/GLA run a 7G-DCT dual-clutch — very different boxes. Find your family below, then send your VIN so suppliers quote the exact unit.
Rear-wheel-drive, longitudinal — the C / E / S-Class & SUVs
The long-serving 5-speed torque-converter auto; one of the easier Mercedes boxes to source in SA.
The 7-speed auto across the C/E/S-Class — its signature fault is the valve body / conductor plate, often the real fix rather than a whole box.
The current-generation 9-speed auto on the newer E/C-Class and the GLC / GLE — usually quoted on application.
Front-wheel-drive, transverse — the small A/B/CLA/GLA + the manual
The transverse, front-wheel-drive 7-speed WET dual-clutch — prone to jerk/shudder from a standstill and clutch/mechatronic wear. Shares no parts with the 722.9 despite both being "7-speed".
The simplest and most affordable Mercedes box — fitted to the diesel and Kompressor C-Class, often reconditioned on an exchange basis.
The RWD cars use a torque-converter 7G/9G-Tronic; the small FWD A/B/CLA/GLA use a 7G-DCT dual-clutch — very different boxes; confirm by VIN. The 722.9 and 724.0 both say "7-speed" but share no parts.
Still not sure? and suppliers will confirm the exact gearbox for you.
On the 722.9 especially, many of these point to the valve body / conductor plate rather than a dead gearbox — so get it diagnosed before you replace the whole unit.
A Mercedes automatic lives or dies on clean fluid and a healthy valve body. A few habits go a long way on SA roads:
The single biggest trap on a Mercedes is assuming "7-speed" tells you the box. The 722.9 7G-Tronic is a longitudinal, rear-wheel-drive torque-converter automatic across the C-Class (W204/W205), E-Class (W212) and S-Class (W221) — its signature fault is the valve body / conductor plate, which is often the real fix rather than a whole gearbox. The 724.0 7G-DCT is a completely different unit: a transverse, front-wheel-drive wet dual-clutch behind the A-Class, B-Class, CLA and GLA, prone to jerking from a standstill and clutch/mechatronic wear. They share no parts, so confirm by model and VIN.
The proven 722.6 5G-Tronic sits behind the W203 C-Class and W210/W211 E-Class era (and petrol Sprinters) — one of the easier Mercedes boxes to source, with used units around R3,500–R9,000. The newer 725.0 9G-Tronic on the W213 E-Class, X253 GLC and W167 GLE is current-generation and usually quoted on application. The cheapest option is the 716.6 6-speed manual on the diesel and Kompressor W203/W204 C-Class, with reconditioned units around R6,500 on exchange.
On the 722.9, rough or jerky shifts and holding a gear often trace to the valve body / conductor plate rather than a dead gearbox, so it is worth a proper diagnosis before committing to a full unit.

It depends heavily on the model and gearbox. As a guide from real SA used listings: a 722.6 5G-Tronic (W203 C-Class / W210–W211 E-Class) is often around R3,500 to R9,000, a 722.9 7G-Tronic (W204/W205 C-Class) around R2,000 to R9,000, and a reconditioned 716.6 6-speed manual around R6,500 on exchange. The newer 725.0 9G-Tronic and the 724.0 7G-DCT dual-clutch are quoted on application rather than listed openly. Prices vary with mileage, condition and whether it's used or reconditioned — request a quote and verified suppliers will price your exact unit.
They're completely different gearboxes that happen to share a speed count. The 722.9 7G-Tronic is a longitudinal, rear-wheel-drive torque-converter automatic in the C/E/S-Class (W204/W205, W212, W221), SLK and CLS. The 724.0 7G-DCT is a transverse, front-wheel-drive WET dual-clutch in the A-Class, B-Class, CLA and GLA. They share no parts, so quoting "a 7-speed" isn't enough — always tell us the exact model so verified suppliers source the correct box.
Not necessarily. On the 722.9 7G-Tronic the classic culprit is the valve body / conductor plate, which causes rough or jerky shifts and holding a gear — and that's frequently the real fix rather than a complete gearbox replacement. It's worth having it diagnosed first. If a full unit is needed, request a quote and verified suppliers can match a used 722.9 to your exact model and year.
That's a known characteristic of the 724.0 7G-DCT wet dual-clutch — jerking or shudder pulling away from a standstill, with clutch and mechatronic wear typically appearing around 70,000 to 100,000 km. Sometimes a clutch or mechatronic assembly is the right repair rather than a whole gearbox. Request a quote and verified suppliers will match a used or reconditioned 724.0 (or the relevant assembly) to your exact car.
Yes — the diesel and Kompressor W203/W204 C-Class use the 716.6 6-speed manual, which is the simplest and most affordable Mercedes gearbox to source and repair. Reconditioned units are seen around R6,500 in SA, often on an exchange basis with a guarantee. Confirm your exact engine and year and verified suppliers will match the right 716.6.
The single most important step is confirming your exact model, year and engine — Mercedes uses several gearboxes that look similar but share no parts, the biggest trap being the 722.9 7G-Tronic torque-converter auto versus the 724.0 7G-DCT dual-clutch. Where possible, confirm the gearbox by VIN. Submit your details and verified suppliers across South Africa send back quotes for the correct unit, so you can compare price and condition before you buy.
