Holden Jackaroo 1992 Problems

There are two possibilities here. Either the shifter mechanism has jammed or failed and will only allow you to select second or fourth or, the gearbox itself has failed internally, and the ensuing mechanical carnage has jammed it up. The wild-card is the clutch which could have failed. If that was the case, though, I’d imagine you wouldn’t be able to select any gears at all with the engine running.

The first step would be to check from underneath whether the gear linkages and selectors have somehow got tangled up in each other – it can happen – but if that’s not the case, then I’m afraid it’s probably a gearbox-out job. Make sure you fit a new clutch when it all goes back together.
