Why is my Jimnys 3 transmission not working?
The most common causes (by far) of 4WD transmission system operation issues in Jimnys 3 are related to the vacuum system for the pneumatically operated free wheeling front wheel hub heads.
What kind of transmission system does bigjimny use?
User selectable part-time 4WD transmission which defaults to RWD 2WD (real wheel drive two wheel drive) mode. Free wheeling hub heads on the front wheel hubs, pneumatically (vacuum) operated. The only operational differences among different Jimny 3 editions / revisions are in the design of the control of the transmission system.
Can a Jimny 2 have a transfer box?
Some Jimnys 2 (SJ410 models specifically) have the transfer box hand brake, so they are an exception. Explanation of the incompatibility: Vehicles with part-time 4WD transmissions (like Jimny 1-4) do not have a center (inter-axle) differential.
