Gearbox replacement or rebuild: price and symptoms
A failed gearbox is expensive — no way around it. What does make a big difference is the choice between rebuilding, a used unit from a Dutch dismantler, an exchange box from a specialist rebuilder or a complete new unit. This page explains how to tell shifting problems from internal damage, what each of the four options roughly costs, and why a second opinion is worth its weight in gold.

What does the gearbox do?
The gearbox translates the engine’s high revs into the wheels’ lower revs, with multiple ratios for different speeds. On a manual the driver shifts via the clutch; on an automatic a hydraulic-electronic system does it. Wear and faults sit in the synchroniser rings (manual), the clutch packs (automatic), the mechatronic control unit, bearings or differential — depending on the type. DSG, CVT and conventional automatics each have their own failure patterns.
Symptoms — honest about what it might be
- Shifting becomes heavy or notchy (manual) — often synchros or the linkage.
- Grinding or graunching sound when shifting (manual) — clutch, dual-mass flywheel or synchros.
- Slipping: engine revs rise without matching acceleration (automatic).
- Jerks or harsh shifts (automatic with mechatronic fault or contaminated fluid).
- A “limp home” mode where the box stays in one gear — flagged via the check-engine light.
- A humming noise while driving straight that scales with road speed — bearings or differential.
- Red or brown fluid leaks under the unit (automatic transmission fluid).
Rebuild, exchange, used or new?
Honest framing: do not replace a gearbox until you are sure. First step is always a second diagnosis — many “gearbox” complaints turn out to be a worn clutch, a fouled mechatronic valve, old automatic fluid or a simple sensor that software or a fluid change resolves. Then choose between: rebuild (€ 1000 – € 4000 with exchange part and fitment warranty), a used box from a Dutch dismantler (€ 200 – € 1800, shorter warranty), an exchange box from a specialist rebuilder (€ 1500 – € 4000 with 1 – 2 year fitment warranty), or a new complete unit (€ 2500 – € 5000+, usually dealer pricing). For older cars a used box with fitment warranty often wins; for newer cars an exchange box with multi-year warranty.
What does a gearbox cost?
The spread is enormous. Indications: a used manual box from Dutch stock € 200 – € 1500. A used automatic € 400 – € 1800. Manual rebuild € 800 – € 2500. Automatic rebuild (incl. mechatronics) € 1500 – € 4000. An exchange box from a rebuilder with 1 – 2 year fitment warranty € 1500 – € 4000. A new complete unit € 2500 – € 5000+. On top of the part comes 8 – 16 hours of workshop labour (€ 600 – € 1400), fresh fluid, a clutch where applicable and possibly a driveshaft seal. Always ask for an itemised quote that mentions **fitment warranty** — at these amounts it is critical.
| Condition | From | To |
|---|---|---|
| New | € 500 | € 5000 |
| Used / refurbished | € 200 | € 1800 |

DIY?
Difficulty:
Honest advice: don’t. A gearbox weighs 50 – 100 kg, sits deep between subframe and exhaust, and has to slide back onto the clutch splines without forcing. One wrong move and the input shaft scores the clutch plate, the box won’t fit, or a seal leaks within 100 km. On automatics there is mechatronic coding and fluid-fill procedures that need brand-specific equipment. For most owners: order the box yourself (used or exchange) from a Dutch seller and have an independent garage or a specialist rebuilder fit it — always ask for **written fitment warranty**.
- A lift — not just axle stands — plus a gearbox jack or cradle
- Full socket set with wide-range torque wrench
- New clutch kit (manual) or new mechatronic pack / fluid + filter (automatic)
- New driveshaft seals, since the [[topic:aandrijfas|driveshafts]] come out anyway
- Time: one to two full days for an experienced wrench
Frequently asked questions
Is it really the gearbox, or something else?
Always get a second opinion before replacing. Many complaints that feel like gearbox damage (slipping, jerking) are in fact a worn clutch, a clogged mechatronic valve, stale automatic fluid or a simple sensor. A € 80 – € 150 diagnosis can prevent a € 3000 bill.
What is the difference between a rebuild and an exchange box?
On a rebuild a specialist opens your box, replaces worn parts and returns it. With an exchange box you get an already-rebuilt unit from stock and hand in your old one as core. Exchange is faster (no downtime) and often comes with longer fitment warranty.
Used or rebuilt?
For older cars (10+ years): a used box with a short fitment warranty usually wins. For newer or premium cars: rebuild or exchange box with 1 – 2 year warranty. For automatics, rebuilt is often wiser than used — internal wear is hard to judge from outside.
What is fitment warranty and why does it matter?
Fitment warranty means the supplier also covers labour cost if the box fails within the warranty period. With a used box on parts-only warranty you pay another € 600 – € 1400 in labour. Ask for fitment warranty in writing.
What does the full job cost realistically?
Manual, used box: € 1000 – € 2500. Manual, rebuilt: € 2000 – € 4000. Automatic, used: € 1500 – € 3200. Automatic, rebuilt or exchange: € 3000 – € 5500. Budget extra for clutch, fluid and small parts that always go with it.
