- Possible cause described
- An excessively tight upper-hose bend can transmit vibration and cause cracks and power loss.
- Check for the garage
- Inspect the upper intercooler hose and routing; replace if damaged with an adequate bending radius.

- Engine / equipment
- Getrag M32 six-speed manual: Opel Astra H and J, Insignia A, Zafira B and C, Vectra C, Meriva B, Cascada, Corsa OPC and some Fiats with the T-Jet engine
- Period mentioned
- 2004–2019
- Symptoms
- A whine that rises with speed, mainly in 5th and 6th (also in 1st and 2nd), a loose gear lever that moves on and off the throttle and, when advanced, gears jumping out. Left unrepaired, the bearing can break through the casing.
- Possible cause described
- The bearings wear, mainly the shaft bearing next to 6th gear: the rollers develop play and the shaft moves under load, which reaches the lever. A specialist blames incorrect factory shimming. Second-generation boxes with the revised end case fail far less, according to an Australian repairer.
- Check for the garage
- In a garage test: confirm whether the noise depends on road speed (wheel bearing, tyre) or the gear engaged (gearbox), and whether the lever moves under load. Check the oil for metal debris. Repair early: replacing all bearings and fitting the revised end case costs far less than a new gearbox.
- Cost cited in the source
- One owner replaced only the main bearing for about £47 in parts versus about £1,000 for a rebuilt gearbox; another quotes about €600 at a specialist.A rough figure from the original database, not an up-to-date quote.
