The Opel R30 5-speed manual transmission was assembled at the German company’s plant from 2000 to 2003 and was installed exclusively in the rear-wheel-drive Omega B, paired with the Y22DTH and Y25DT diesel engines. This transmission was also installed in police versions of the Omega, paired with the Y32SE gasoline engine.

Disadvantages of the Opel R30 gearbox
- This is a very reliable manual transmission, but its service life is highly dependent on operating conditions;
- Overly active owners may experience short-lived first-gear synchronizers;
- The input shaft bearing may begin to hum and require replacement as early as 150,000 km;
- The plastic ring and bushings on the lever also often break, causing it to wobble;
- Continuing to drive like this will soon result in grease leaks through the gearshift seals.
