Allison Transmission's new Hungary factory has begun production of fully automatic transmissions for international customers.

Within weeks, a new customisation centre in the Szentgotthard facility will open. By configuring transmissions to specific customer requirements prior to shipping, the company will shorten a vehicle's drivetrain assembly time, while increasing the OEM's overall build efficiency.

"For over 10 years we enjoyed sharing a manufacturing facility in Szentgotthard with General Motors Opel Hungary, said David Parish, Allison Transmission operations chief.

"I want to thank GM Opel for their support and assistance in the construction of our new Allison wholly-owned manufacturing plant."
