Note:
Because the individual parts to repair the spur gear assembly are no longer available, the repair procedure for "Setting tension on spur gear roller bearing" in the workshop manual is no longer valid. This should be noted in the shop manuals 911 Carrera 214 Volume 3 pages 39-108a to 39-108b and 911 Carrera (993) Volume 3 page 38-127. The repair manuals will be revised at a later date to reflect this change.

Repairs:
The vent valve that is supplied with the complete spur gear set must be pressed into the intermediate plate after the spur gear set has been installed on the transmission.

Repairs may be performed involving external parts (valve body, pump. sensors or differential). If repair to the automatic section of the transmission is necessary. then the entire transmission must be replaced.
