ATSG AUDI GEARBOX TRANSMISSION Technical Service Information
ATSG AUDI 01J MULTITRONIC GEARBOX TRANSMISSION Technical Service Information Manual
2004 Audi A4 and A6
1.8L and 3.0L
Some Audi A4 and A6 vehicles are equipped with the Multitronic® 01J (VL300) Continuously Variable
Transmission. One of the more unique features about this transmission is the fact that the Transmission Control
Module (TCM) is located INSIDE the transmission with the 25 pin TCM connector for early units and a round
20 pin TCM for later units protruding out the rear of the unit.. This transmission does not use a torque converter,
it uses a dual mass flywheel or a flywheel/damper plate assembly depending on engine size. Another of the
unique components of the 01J is the use of a drive chain instead of a belt. This is the first time a drive chain has
been used in a CVT application. The TCM operates several external relays through the same harness as the one
that connects to the back of the transmission case. The TCM also communicates with other modules over the
CAN Network. The Tiptronic gear selection feature provides six (6) or seven (7) manually selected speeds.
