Parts for your 1998 Mitsubishi Pajero-Transmission fluid

1998 Mitsubishi Pajero transmission-fluid

Transmission-fluid is absolutely relevant for the 1998 Mitsubishi Pajero when it’s fitted with an automatic gearbox and the Super Select transfer case. Mitsubishi’s owner’s handbook and workshop literature for the V20-series Pajero specify Mitsubishi Diaqueen ATF SP-III (or an approved equivalent meeting SP-III) for the auto and transfer case. Manual gearboxes on the same model use dedicated manual transmission/gear oil rather than ATF, so the exact fluid type depends on whether the vehicle is auto or manual.

On auto Pajeros, transmission-fluid does a lot of heavy lifting. It lubricates internal components, carries away heat, provides hydraulic pressure to engage clutches and bands, and delivers the right friction characteristics for smooth shifts. Fresh, correct ATF keeps shift quality crisp, helps prevent shudder, and protects against varnish and wear. The Super Select transfer case also relies on ATF for clean engagement between 2H, 4H and 4HLc.

For servicing, most technicians follow Mitsubishi’s guidance to inspect ATF regularly and replace it at sensible intervals. In Aussie and NZ conditions—think towing, beach work, hill country, or stop–start commuting—a change every 40,000–60,000 km (or 3–4 years) is a smart move. Light-duty vehicles can often stretch further, but time degrades fluid too. Always use Mitsubishi ATF SP-III, don’t mix in Dexron/Mercon fluids, as the friction profile is different.

Level checks matter. With the vehicle level, handbrake on, engine idling and the fluid warm, cycle the selector slowly through all gears, return to Neutral, and check the dipstick against the “HOT” marks. The fluid should be clean and cherry-red, a dark, burnt smell means it’s due—or overdue. When changing ATF, consider:

• Multiple drain-and-fills a few hundred kilometres apart if you want a higher proportion of new fluid without a machine flush.
• Replacing the pan gasket/filter (where fitted), cleaning the magnet, and torquing pan bolts correctly.
• Inspecting cooler lines and the radiator ATF cooler for leaks or restrictions.

For manual 1998 Pajeros, use the specified manual gearbox oil to the correct GL rating and viscosity, it’s not ATF, but it’s just as critical—especially if the vehicle tows or sees off-road use. Either way, the right fluid, the right level, and sensible intervals keep a 1998 Pajero shifting sweet and running cool for the long haul.

Popular questions

What transmission fluid does a 1998 Mitsubishi Pajero take?
Automatic gearboxes and the Super Select transfer case require Mitsubishi Diaqueen ATF SP-III (or a fluid explicitly approved to the SP-III spec). Manual gearboxes use dedicated manual transmission/gear oil to the correct GL rating—don’t substitute ATF in a manual.

How often should the transmission fluid be changed on a 1998 Pajero?
In Australian and New Zealand conditions, many workshops recommend changing ATF every 40,000–60,000 km or 3–4 years, sooner if towing, dune driving, or in hot, hilly terrain. Light-duty vehicles can go longer, but age and heat still break fluid down.

How do you check the ATF level on a 1998 Pajero?
Park level, handbrake on, engine idling, and fluid warm. Slowly cycle the selector through all positions, pause in each, then leave it in Neutral. Pull the dipstick, wipe, reinsert, and read against the HOT marks. Top up only with SP-III, and avoid overfilling.
