5th Gear Repair Kit 39 / 48 02T311361A 02T311158N

02T Gearbox 5th Gear Repair Kit 39T / 48T – 02T311361A & 02T311158N for Audi / SEAT / Skoda / VW

A matched 5th gear replacement pair for the Volkswagen Group 02T / 0AF / 0AP 5-speed manual gearbox. The 02T gearbox has a well-known 5th gear failure mode: when the input shaft bearing collapses, it allows the 5th gear set to move out of true, rapidly destroying both the input and output gears. This kit replaces both gears simultaneously to restore a clean, matched mesh.

Kit includes:

• 1 × 5th Speed Input Gear 39T (02T311361A)
• 1 × 5th Speed Output Gear 48T (02T311158N)

Fits transmission: 02T (5-Speed) · 0AF (5-Speed) · 0AP (5-Speed)

OE Part Numbers: 02T311361A · 02T311158N

Why does the 02T gearbox 5th gear fail?

The 02T is prone to input shaft bearing collapse at higher mileages, particularly in cars used for extended motorway driving. When the input shaft bearing collapses, the shaft can move axially, causing the 5th gear teeth to contact incorrectly and wear rapidly. Both gears must be replaced together — replacing only one leaves a new gear meshing with a worn partner.

Should I also replace the input shaft bearing when fitting this gear kit?

Yes — always identify and address the root cause of the 5th gear failure. If the input shaft bearing has collapsed (which is the most common cause), it must be replaced at the same time. Fitting new gears without replacing a failed bearing will result in rapid repeat failure.

Which vehicles use the 02T / 0AF / 0AP gearbox?

The 02T gearbox family was fitted to a wide range of compact VAG vehicles including: Audi A1, A2 · SEAT Praktik, Cordoba, Ibiza, Toledo · Skoda Fabia, Rapid, Roomster · VW Bora, Fox, Golf IV, Lupo, New Beetle, Polo IV/V. Please confirm your gearbox code before ordering.

Can this gear kit fix a gearbox that slips out of 5th?

Yes — if 5th gear is slipping out under load or refusing to engage, worn 5th gears are a primary cause. Replacing the gear pair along with the input shaft bearing typically resolves the fault. If the synchromesh is also worn, that may need attention too.
