Rally drivers go through an average of 3,500 gear changes in one rally.
Here is some more information about the transmissons:
"A team of five specialist technicians build, on average, 10 completely new gearboxes a year to maintain an operating stock of 16 units. These are used in the team's two rally cars on a rotation basis, with a complete re-build after each event (typically 500km). As Paul Roberts, transmission supervisor told us "Assembling a Subaru WRC gearbox is a highly skilled job that will take a technician approximately 80 hours to complete. There are 350 individual components in each gearbox, but many more in the whole transmission system. Taking parts and labour into account, each unit costs us around £75,000." On event the team take two gearboxes per car and around £10,000 worth of spare parts for each unit. With no spare time to investigate any gearbox faults during a rally, at the first sign of trouble technicians will switch to the spare unit. WRC regulations permit unlimited gearbox swaps during each event, but as the units are sealed by scrutineers, repairs to the spare unit are limited to external components. For this reason many of the electronic and hydraulic components are externally mounted, to allow swift access. With an average of four highly skilled technicians involved in the process, it takes just 15 minutes to change the gearbox. "
