Why the range is so wide
A classic Porsche gearbox is not a component with a fixed price but an individual case. Two gearboxes of the same type, both fifty years old, can differ by a factor of ten in the work they need.
At the lower end is a gearbox that has run but was looked after: synchro rings, bearings, shaft seals and small parts are due, the gears are usable and the final drive carries cleanly. Work of that kind comes to around 1,400 euros net.
At the upper end is a gearbox where load-bearing parts have to be replaced that have not been available for decades. We then make them new — gears, shafts, stub axles, complete final drives. The ceiling there is around 15,000 euros net.
Racing gearboxes are a case of their own. A gearbox for the RSR starts at around 20,000 euros net and is open-ended, because almost every part is a special production.
All figures are net, that is, before VAT. For private customers that comes to roughly 1,670 to 17,850 euros gross, and from about 23,800 euros for a racing gearbox.
What determines the price
Condition of the gears
Worn teeth are the single largest cost item. If the gears are usable, it stays inexpensive.Availability of parts
What can still be bought is cheaper than what we remanufacture from a pattern.Housing
Worn bearing seats can be machined, oversized coated bearings fitted or new bearing mounts shrunk in — each step costs more.Extras
A limited-slip differential, a different ratio or spray-oil cooling are additional work, not repair.Earlier repairs
A gearbox someone has already been into often costs more than one in original condition — particularly where the final drive was set up incorrectly.
How you get to a binding price
A sound fixed price is only possible after the gearbox is stripped. So the order of work is:
- Send in the gearbox — how that works is set out on Send In Your Gearbox.
- Strip and measure — every part is cleaned, inspected and measured.
- Binding quotation — you receive a breakdown of what is genuinely needed and decide how far the rebuild should go.
- Work begins only after your approval.
You are not paying into the unknown. And you get every replaced part back, along with photographic documentation of the work.
Is a rebuild worth it at all?
On a classic Porsche, almost always. A properly rebuilt gearbox lasts decades again, and a car with a documented gearbox rebuild is worth more on resale than one with an unclear history. The point of comparison is rarely a new gearbox — for these types there is none — but a used one with unknown internals.
If you are unsure whether the work is worth it, send the gearbox in for assessment. After the strip-down you will know where you stand.
