The Getrag F20 5-speed manual transmission was fitted to many vehicles in the European General Motors production line up including for the UK the Vauxhall Astra DOHC 2.0i GTE 16 valve, Vauxhall Cavalier GSi 2000 16 valve DOHC and Vauxhall Calibra 2.0i 16 valve DOHC.
The clutch is cable-driven, and has a big fork on the outside-top part of the housing.
It has a cover in the bell housing that lets you change the clutch disc without taking off the gearbox.
It has a lot of similarities with the Getrag F16 Gearbox, that has a weaker main shaft.
As an example the F20 transmission was fitted to the Opel Calibra, Vectra A, Astra F & Kadett E with C20XE 2.0l 16V Engines.
