The Japanese company AISIN Co., LTD is the
manufacturer and developer of the Rear Wheel Drive
TR-60SN transmission, which is a 6 speed, fully
automatic and electronic controlled gearbox.
Volkswagen engineers were also involved, in
conjunction with Aisin, in the development process
for their vehicles and they gave it the 09D
designation. Vehicle applications and transmission
codes known at time of printing, are shown in Figure
1.
The 09D transmission is used in a wide variety of
applications and engine sizes. As a result, the number
of friction plates and three or four pinion carriers, will
vary depending on torque load requirements of the
specific vehicle. The 09D transmission uses a gear
ratio sensitive system, requiring the correct
transmission interchange, if that becomes necessary.
The Transmission Control Module (TCM) is
mounted external from the transmission which makes
typical electrical diagnosis available to the
technician.
The TCM controls both shift timing and shift feel
with the use of eight solenoids. The TCM monitors
gear ratio through the input and output shaft hall effect
speed sensors. It also can determine the rate of change
and adapt the shifts as the friction elements wear.
TR-60SN (09D) transmissions use a Lepelletier type
gear set arrangement, which consists of a simple
planetary with the sun gear splined to the pump stator
and coupled with a Ravigneaux type, dual planetary.
This is similar to but not the same, as the type of
planetary that was used in the FMX. This arrangement
allows the sun gears and the planetary pinions of the
Ravigneaux planetary gear-set to be driven at
different speeds and makes six forward speeds and
reverse possible, with only five clutch packs and one
freewheel.
Lepelletier's brilliant idea has led to several different
manufacturers using this gear set arrangement in their
own versions of six forward speeds transmissions.
Refer to Figure 2 for the component locations and the
clutch application chart for each gear.
