Porsche 914 Gearbox Rebuild

Full rebuild, limited-slip differential, spray-oil lubrication as on the 914/6 GT

For the 914 gearbox we offer the complete rebuild, the matching limited-slip differential and the spray-oil lubrication the factory ran in the 914/6 GT — motorsport engineering for the mid-engine classic.

What we do on the 914 gearbox

Complete rebuild
strip, measure, recondition, set up — including test-bench run and return of all replaced parts.
Limited-slip differential
available as a 914 version, locking value 25–75%, homologation-ready.
Spray-oil lubrication in 914/6 GT style
the factory motorsport solution, retrofitted during the rebuild.
Speedometer drive
conversion from mechanical to electronic or back.

Typical problems this solves

Notchy shifting — on the 914 often a combination of linkage and worn guide sleeves inside the gearbox
Overheated gearbox oil in spirited use
No limited-slip differential available for slalom, hillclimb or historic rally

Common questions

01 Is there a limited-slip differential for the Porsche 914?

Yes, the 914 version is available from stock. Locking value 25 to 75 per cent, suitable for homologation.

02 What is spray-oil lubrication after the 914/6 GT pattern?

The factory motorsport solution from the 914/6 GT against overheating gearbox oil under competition use. We retrofit it during the rebuild.

03 Why does my 914 shift stiffly?

On the 914 it is often a combination of the shift linkage and worn guide sleeves inside the gearbox. Only a strip-down shows which part dominates.

What is on your bench?

Gearbox type and a few lines about your request — that is all we need for a first assessment. A photo helps but is not required. The answer comes from the machinist, not from sales.
