Volkswagen 01M Transmission. Manual - part 100

"Observed" K1 and K2 Pressures, at operating temperature with a new valve body installed.
  Initial engagement N to D; K1 pressure at idle is 56-60 psi.
  Under acceleration in D; K1 pressure is 75-80 psi.
  Before the 1-2 shift in D;   K1 pressure raises to 140-150 psi.
  When shift is completed;   K1 pressure settles at 80-90 psi in 2nd gear.
  Before the 2-3 shift in D; K1 pressure raises to 95-100 during 2-3 shift and settles at 70 psi in 3rd.
  Before the 3-4 shift in D; K1 pressure raises to 140 psi, K2 pressure still under 4 psi. Then K1 pressure begins to drop
and K2 pressure begins to rise with both settling at 85-90 psi in 4th gear.
  During 4-5 shift in D;   K2 pressure raises to 190-200 psi, K1 pressure raises to 155-160 psi, then K1 drops to 40 psi,
  (While K2 is 170), then drops gradually to less than 2 psi, and K2 settles at 140 psi in 5th gear.
  During 5-6 shift in D; K2 pressure drops to 110-120 in 6th gear.

Technical Service Information

   There are two distinctly different style lubrication
systems used in TF-60SN (09G/09M) transaxles.  As
a  result,  there  are  2  different  transaxle  cases,  2
different  converter  housings  and  2  different  valve
body to case spacer plates.

  Some models use an ATF cooler that is mounted  on
the converter housing and integrated into the engine
cooling  circuit,  as  shown  in  Figure  35.    With  this
arrangement,  cooler  fluid  is  sent  directly  into  the
cooler and returned to the lube circuit.
   Engine coolant is piped to the integral cooler and
returned  to  the  cooling  system  with  a  constant
circulation.

Some models use an ATF cooler that is mounted in a
remote location, also shown in Figure 35, and cooler
fluid must be sent via traditional cooler lines to the
cooler. This requires entry and exit points located in
the transaxle case, and their locations are shown in
Figure 35.

    Caution:    If  a  mis-match  of  any  of  these  parts
occur,  lubrication  fluid  is  lost  causing  immediate
failure of the transaxle drive train.
   Pay very close attention to the passage ID section
that  follows,  as  it  provides  a  way  to  identify  these
parts, to avoid disaster.
