A family MPV sold by the Japanese manufacturer from 1983 to 2003, the Mitsubishi Space Wagon went through three generations, the last of which launched in 1997. Its gearbox is one of the components that most determines its longevity: on an older vehicle already known for high transmission oil consumption, keeping on top of the transmission is anything but optional. Here is how to look after the gearbox on your Space Wagon and what to do when a fault develops.
The Mitsubishi Space Wagon Transmission at a Glance
The Space Wagon is front-wheel drive as standard, sending power to the front wheels to improve handling and keep fuel consumption in check. Less commonly for this class of vehicle, a four-wheel-drive version was also offered: all four wheels become driven and a transfer case distributes the torque. In terms of ratios, the Space Wagon comes with a five-speed manual gearbox as standard, with a four-speed automatic available as an option.
This MPV uses a considerable amount of both transmission oil and engine oil. This characteristic calls for extra vigilance: neglecting the lubricant level will sooner or later result in premature wear of the gears and synchromesh rings.
Monitoring Transmission Oil to Protect the Gearbox
Check the Level Regularly
On modern gearboxes, transmission oil is typically changed every 60,000 kilometres or so — every two years for an automatic gearbox and every five years for a manual. Because the Space Wagon is an older vehicle with a notably high oil appetite, it is wise to inspect the fluid level and condition more frequently. The dipstick has two marks: if the level falls below the lower mark, top it up without delay. Take the opportunity to check the colour of the oil; if it has turned black, it is saturated with metal particles and is no longer providing adequate lubrication.
Carrying Out an Oil Change
An oil change can be done with basic tools. Park the vehicle on a level surface and raise it, place a drain tray beneath the sump, unscrew the drain plug and allow the fluid to drain fully. Replace the O-ring seal if necessary, then pour in fresh oil using a funnel, following the service manual specifications precisely. Start the engine, engage each gear in turn — including reverse — then check underneath the vehicle for any leaks.
When the Problem Goes Beyond Routine Maintenance
If the gearbox develops a fault despite regular servicing, only a mechanic will be able to pinpoint the exact cause before carrying out any work. Most issues can be dealt with at a garage, but widespread wear sometimes makes a complete gearbox replacement necessary. As the Space Wagon is no longer in production, new parts are unavailable and second-hand units of unknown history carry real risk: a reconditioned gearbox on an exchange basis offers a controlled, fully refurbished solution with no compromise on safety.
Frequently Asked Questions
How often should the Space Wagon gearbox oil be changed? On this older MPV with its high oil consumption, it is best to check the level frequently and plan oil changes at shorter intervals than usual, referring to the service manual for guidance.
How do I know if the oil needs changing? Oil that has turned black, fallen below the minimum mark, or is accompanied by noises and difficult gear changes should be replaced without delay.
Can you still find a gearbox for the Space Wagon? Yes: the scarcity of new parts can be overcome through exchange or by having your own gearbox reconditioned.
Is the gearbox the same on front-wheel-drive and four-wheel-drive versions? No: the four-wheel-drive version adds a transfer case. You will therefore need to identify the exact configuration of your vehicle before any replacement.
