Is the Xpander's 4-speed automatic outdated?

It's old technology and that's the point — it's simple, proven and cheap to maintain. Serviced on time, it will likely outlast most CVTs in the same segment.

Mitsubishi.

Mitsubishi in Malaysia means two very different gearboxes: the simple, rugged 4-speed automatic in the Xpander — an old-school unit chosen deliberately for durability — and JATCO CVTs in the ASX, Outlander and older Lancer. The 4AT just needs fluid; the CVTs need the same vigilance as any JATCO.

Xpander · ASX · Outlander · Triton · Lancer

What's fitted

Unit	Type	Found in	Specialist note
4AT (INVECS-II)	Conventional automatic	Xpander, Triton (older)	Deliberately simple; hugely tolerant, cheap to service and rebuild.
JATCO CVT8	CVT	ASX, Outlander	Same family as Nissan's CVT8 — same heat sensitivity, same fluid discipline required.
INVECS-III CVT	CVT	Lancer, Grandis (older)	Aging units now; belt and bearing wear common at high mileage.

Known failure modes

Fault 01

Xpander harsh kickdown

Usually normal 4AT behaviour amplified by degraded fluid — a service restores smoothness. Genuine faults are rare on this unit.

Fault 02

ASX/Outlander CVT overheat in hills

JATCO heat protection engages on long climbs; fluid and cooler service is preventive, not optional, on these.

Cost band · Malaysia

RM 250 (diagnosis) to RM 6,500 (CVT overhaul); 4AT overhaul RM 3,000–4,000

Exact pricing depends on the diagnosis — see the full 2026 cost guide for how quotes are built and the questions that keep them honest.
