Potential 9 Speed Transmission Issues

We'd like to hear from owners who are experiencing issues or faults with the 9 speed automatic transmissions in their GWM Cannon, Alpha, Tank 300, or Tank 500.

Have you experienced any of the following issues or symptoms?

•Harsh gear changes

B •Thumping or clunking sounds when starting the vehicle

C •Thumping or clunking sounds when shifting into drive or reverse

D •Delayed response when engaging reverse or drive

E •A sudden jolt after coming to a complete stop

F •Lack of acceleration when taking off from a stationary position (you may think this is throttle or turbo lag; but the vehicle may be stuck in a 'false' gear)

G •Inability to reach or maintain 9th gear at highway speeds

•Any other issues (please describe in as much detail as possible)

If any of these sound familiar, we encourage you to fill out the contact form on this page. We're working to address these issues, not only for current owners but for future ones as well. Rest assured, your information will remain confidential and will only be shared with Forbidden Gearhouse Pty Ltd. Once we've gathered enough data, we will reach out to those who filled in the form with next steps.

Thank you for your help!
