The cutaway view of the trans-

mission (figure 2) shows the clutch
layout. When used with the applica-
tion chart, it allows you to deter-
mine which clutches apply through
all six speeds (figure 3).
Although this transmission is
 just now hitting the shops, one
known problem is the inner under-
drive piston  lip seal wears pre-
maturely (figure 4). This causes a
delay or slip in drive. This is similar Figure 2
to low clutch lip seal wear found
in the 1999-on Subaru 4EAT Phase II, except this drum may
 be too rough to sand and must be replaced (figures 5 and 5A
 page 22).
There are 8 solenoids used in the A6LF1 transmission.

They consist of:

 2 normally low, variable force solenoids
 4 normally high, variable force solenoids
 2 on/off normally low solenoids

IMPORTANT: Many
of the variable force
solenoids � both
normally low and
normally high �
have the same
color connector.
Shift solenoid A (SSA) and
shift solenoid B (SSB) are the on/
off, normally low (N/L) solenoids.
When the solenoid is off, pressure
in the circuit is low. When the
solenoid is energized (system volt-
age), pressure in the circuit is high Figure 6
(71 PSI). The solenoid resistance
is about 10–11 ohms. Look for
solenoid identification and solenoid
apply chart in figures 6 and 7.
IMPORTANT: Many of the
variable force solenoids — both
normally low and normally high
 — have the same color connector.
But each solenoid has a specific
 part number stamped into them.
To avoid crossing the solenoids,
mark each solenoid location prior
to removal, so you can be sure to
get them back in their original loca-
tions. If you have your cell phone
handy, take a picture of the solenoid
locations for reference during reas-
sembly.
Stay tuned for future articles
and seminars on Kia’s very first
transmission that’s all its own.
