CVT ZF CFT30

The ZF CFT30 or Ecotronic continuously variable transmission was produced in the USA from 2004 to 2007 and was installed on a number of Ford or Mercury models for the local automotive market. The transmission is designed for engines up to 3.0 liters, so the drive here is in the form of a pulling chain.
