Gearbox removal & installation: Suzuki Swift (M13A, M15A)

🧭 Before you start

Release fuel pressure, disconnect and remove the battery and tray, then remove the air filter, washer hose and left engine cover. Remove the air-conditioning belt and unbolt the compressor without opening it, drain the gearbox oil and disconnect all engine and gearbox wiring, cables, hoses, fuel lines, clutch hose, gear-shift and exhaust. Remove the front wheels and drive shafts, support the engine, check nothing is still connected, remove the mounts and lower the engine and gearbox out underneath, then separate the gearbox. Refit in reverse and check for leaks.

Fits: platform codes 1.3, |, 1.5

• Opens: gearbox oil, fuel

Don't miss

• Release fuel pressure before disconnecting any fuel line.
• Leave the air-conditioning compressor connected and tie it aside; do not open the refrigerant circuit.
• Drain the gearbox oil before removing the drive shafts.
• Go round once more before lowering: every wiring connector and hose must be free.
• Check for leaks after refilling and correct if necessary.
