Delayed engagement and a jerk between gears on a Pajero IV auto is usually a hydraulic pressure problem, not a dead gearbox.
Here’s what to check first, and when it stops being safe to drive.
Why your Pajero IV pauses, then thumps into gear
If your Pajero IV's automatic feels like it hesitates, flares, or slams into the next gear, you're not imagining it — and you're not alone. The five-speed Aisin unit (V5A51/V5A5A) behind most 3.2 DiD and 3.8 V6 Pajeros is a genuinely tough box, but by 150,000–250,000 km the valve body, solenoids and clutch packs start showing their age. A one-to-two-second delay before engagement, followed by a jerk when it finally bites, almost always points to a hydraulic pressure problem rather than a mechanically destroyed gearbox. That's good news, because pressure faults are usually repairable without pulling the transmission out.
