friction disc kit said to fit 2003-up (except Transporter 2006-up) - 21 discs
There might be discs of different thicknesses and/or diameters and/or number of teeth for C1, C2, C3 and B2 for 09G (TF60SN), 09K (TF61SN) and 09M (TF62SN) available. It is possible that the transmission manufacturer used different clutch packages in otherwise identical transmissions. This might not be realized until the transmission was opened for repair/overhaul.
