Installing gearbox, Audi A1 quattro — AUDI

🧭 Before you start

Install the gearbox with the engine after checking the oil seals and the cover in front of the rear splined shaft seal. Prepare the splines, confirm the dowel sleeves and intermediate plate, and check the release bearing, renewing the slave cylinder with bearing if worn. Once in, bleed the clutch, adjust the selector mechanism and check oil levels in the gearbox and the bevel box.

Fits: Audi A1 (8X, 2010–2018)

• Opens: clutch fluid, gearbox oil
• Renewed: if necessary

Don't miss

• Missing dowel sleeves cause gear-change problems, clutch malfunction and rattling gearbox noise.
• Wipe off excess spline grease once the clutch hub slides freely on the shaft.
• If the release bearing is worn, renew it together with the clutch slave cylinder.
• Check the oil level in the bevel box as well as in the gearbox.
• Inspect the oil seals and the cover in front of the rear splined shaft seal before installation.
