Porsche® 911/930 Turbo Transmission, Synchro Ring, 3rd-4th Gear, 1976-1989
- 2 Each Required
- The Cure For Hard Shifting
The synchro rings are friction rings that spin up the transmission to match the drivetrain prior to shifting. This allows the gears to mesh without grinding. As soon as the synchro rings begin to wear, then the gears start to mesh at different speeds, resulting in gear grinding.
Synchro rings should be replaced as soon as gears begin to grind. Failure to do so will result in damage to the sliders and the synchro hubs which are much, much more expensive to replace.
Don't get worn out stressing about crunching gears - replace your synchros.
