Disadvantages of the Opel F13 gearbox

• This manual transmission operates normally with engines up to 1.4 liters and doesn’t cause any particular problems;
• However, with 1.6 and 1.7 liter engines, the synchronizers and differential quickly fail;
• The secondary shaft bearings also fail, causing significant play;
• The gear selection mechanism in this manual transmission also has a short lifespan;
• Seal leaks are common, and low lubrication levels reduce the transmission’s lifespan.
