Conductor plate and valve body

How you know it is this

• Harsh or delayed shifts, especially cold
• Stuck in one gear, or limp mode
• The gear display flickering or showing nothing
• A speed sensor fault, or implausible gearbox signals
• Red fluid at the gearbox electrical connector

Worth knowing before you buy

• ON THE 722.9 THIS IS THE COMMON FAULT AND IT IS NOT A GEARBOX. Many cars condemned as needing a gearbox need this instead, at a small fraction of the cost. Always establish which before ordering anything large.
• The site's gearbox reference sets out why the generation matters: early 722.9 units built 2004–2008 are VGS1 and usually need the valve body AND the conductor plate; later VGS2 and VGS3 can often be done with the conductor plate and control unit alone. That decides the price, so establish it first.
• The plate is usually coded or adapted to the car after fitting.
• Done with the pan, filter and fluid, since the box is open anyway.
