240Z / 260Z / 280Z

1969-1978 / Coupe / Japan

Common Drivetrain

Gearbox Synchro Wear (5-speed)

Symptoms

Grinding or crunching when shifting into 2nd or 3rd gear, particularly on quick shifts or cold starts.

Cause

The synchro rings wear with age and enthusiastic use. Second gear takes the most abuse in normal driving.

Fix

A gearbox rebuild with new synchro rings, bearings, and seals.

Cost: $1,000-2,000 for parts and labour.

Alternatively, a good used gearbox can be sourced for $500-1,000.

The 280Z 5-speed is the strongest unit and the most desirable replacement.
