The Volkswagen shift linkage is not adjustable. When shifting becomes difficult or there is an excessive amount of play in the linkage, check the shifting mechanism for worn parts. Make sure the shift linkage coupling is tightly connected to the inner shift lever located at the rear of the transaxle under a plate below the rear seat on Types 1 and 3. On Type 2 models, Check the setscrew where the front shift rod connects to the center section below the passenger compartment, and the rear setscrew where the linkage goes into the transaxle. Worn parts may be found in the shift lever mechanism and the supports for the linkage rod sometimes wear out.
