My Disco 2 (Manual) also has slightly poor synchro and needs deliberate gear changing to avoid crunching, it's on 145,000 is this just normal or might an oil change help? Is it fairly easy to drain /refill the box?
Easy enough to change the oil and from experience its a common issue on the Disco gearbox. Its a slow box at the best of times and is easy to buzz the syncro if you change at anything other than a slow deliberate change.
