Common Clutch and Gearbox

PG1 Gearbox -- Second Gear Synchro Wear

Symptoms

Crunching or resistance when shifting into second gear, particularly on cold downshifts from third to second.

Cause

The PG1 gearbox is generally robust, but the second gear synchromesh takes the most punishment in normal driving. The brass synchro ring wears thin and can no longer match shaft speeds.

Fix

  1. 1 Gearbox rebuild with new synchro rings. Cost: $800--1,500 for a rebuild. The gearbox must come out, which means the subframe comes down -
  2. 2 similar labour to a clutch job. Do the clutch at the same time if it has any age on it. A replacement gearbox from a breaker ($400--800) is sometimes more economical than a rebuild
