Gearbox and Differential Repairs in Sandton and Midrand

RS Service Centre diagnoses and repairs manual and automatic gearboxes and differentials on every make at our Sandton (Wynberg) and Midrand (Halfway House) workshops, with dealer-level diagnostics, OEM-grade parts and a 10,000km or 6-month workmanship warranty. Quotes are free. If your car needs a full rebuild or brand-specific transmission work, our sister company RS Gearbox & Differentials handles it under the same roof, so you only ever deal with one team.

Warning signs your gearbox or diff needs attention

Book a check as soon as you notice any of these:

• Slipping or hunting between gears. The engine revs rise but the car does not pull as it should. Common in automatics, and often a fluid or clutch-pack issue if caught early.
• Grinding, crunching or a stiff shift. In a manual this points to the clutch, synchros or linkage. In an automatic it can be a worn component or low fluid.
• Delayed or harsh engagement. A pause or a thump when you select Drive or Reverse.
• A whine or hum that changes with road speed. A classic differential symptom, especially on rear-wheel-drive and 4×4 vehicles. A clunk on take-off or when lifting off the throttle points the same way.
• Shuddering at low speed. Often a torque converter or dual-clutch (DSG type) symptom.
• Gearbox warning light or limp mode. The car holds one gear and limits power. Stop driving it hard and get it scanned.

Not every one of these is a gearbox failure. Worn engine or gearbox mounts, drive shafts, CV joints and clutch hydraulics are frequently mistaken for transmission faults. Our first job is to confirm what is actually wrong before anyone talks about a rebuild.

What a gearbox or differential repair involves

Diagnosis first

We start with a road test and a full scan on dealer-level diagnostic equipment, then check fluid level and condition, mounts, linkages, drive shafts and the differential for play and noise. You get a written quote that explains what we found and what we recommend, in plain language, before any work begins.

Servicing and repairs we do at RS Service Centre

• Gearbox oil and filter service (manual, automatic, CVT and dual-clutch), set to the manufacturer’s specification
• Differential oil change and inspection, including limited-slip units
• Seals, gaskets and leak repairs
• Mounts, linkages, cables and selector faults
• Clutch and clutch hydraulics on manual vehicles
• Repairs that can be completed without removing and stripping the unit

Rebuilds and specialist transmission work

Full automatic and manual rebuilds, torque converter work, CVT and DSG repairs, differential rebuilds and transfer case repairs are carried out by RS Gearbox & Differentials, our sister company. Their in-depth fault-finding diagnostic is charged at R750 and the fee covers the full assessment and a recommended repair solution.

What affects the cost of a gearbox or diff repair

We do not publish a flat price because no two gearbox jobs are the same. The quote depends on:

• What is actually faulty. A fluid service or a mount is a very different job from a clutch pack or a bearing inside the unit.
• Manual, automatic, CVT or dual-clutch. Automatics and dual-clutch units carry more parts and more labour time.
• Repair, rebuild or exchange unit. Sometimes a reconditioned exchange unit is faster and cheaper than opening yours.
• Parts availability for your make. Some European and newer Chinese models take longer to source.
• How far the damage has spread. Metal in the oil usually means more components are affected, which is why early diagnosis saves money.

Every quote is free and itemised, and nothing is fitted without your approval.
