01E 6-speed manual transmission

Overview

The 01E 6-speed manual transmission came in some B5 S4s, C5 A6s and Allroads

Fluid

Capacity: 3.2L Type: GL4 75-90wt synthetic gear oil

Common Problems

• Brass synchronizers wear prematurely. These are often replaced with composite synchronizers.
• At time of Manufacture All 01E transmissions were equipped with a 1st and 2nd gear shift collar with a tolerance that is very tight. Because of this any wear will cause the collar to lock up and prevent the transmission from being shift into or out of 1st or 2nd gear. This is commonly replaced with an updated version.

Modifications and Repairs

Rebuild

• Advanced Automotion rebuild kit
• JHMotorsports rebuild kit

The JHMotorsports transmission rebuild DVD is very helpful along with the Bentley manual.

Metal slave cylinder upgrade

The OEM plastic slave cylinders can create and leak. The internal pistons can also be overextended and ejected from the cylinder requiring replacement. The metal cylinder does not suffer from these problems.

A metal slave cylinder is made by Sachs part #7372-01060755.
