You summon the exact nonmagical part you need to temporarily repair a vehicle within range. The part is instantly installed, and any penalty incurred by damage or a flat tire is ignored while the spell is active. When the spell ends, the part disappears, leaving a greasy sheen behind, and the damage or flat tire returns until repaired.
