When connecting torque converter to trans-
mission, measure distance "A" to be certain
that they are correctly assembled.
Distance "A":
More than
35 mm (1.38 in)
Install converter to drive plate
Align matching marks painted across both parts
during disassembly.
Before installing torque converter securing
bolts, apply locking sealer to threads

in transmission.
Move selector lever through
all positions to be
sure that transmission operates correctly.
With parking brake applied, rotate engine
at
idling Move selector lever through "N" to
"D", to "2". to "1" and to "R" A slight shock
should
be felt by hand gripping selector each
time transmission
is shifted.
Check to be sure
that line pressure is correct.
To do this, refer to Line Pressure Test
Perform stall test.

through end of
rear extension, and place trans-
mission on
Tool.

2 Remove lock-up solenoid (E4N71B).
3. Remove converter housing.

4. Remove oil pan and inspect its contents. An
analysis of any foreign matter can indicate the
types of problems to look for. If the fluid
IS
very dark, smells burned, or contains foreign
particles, the frictional material (clutches,
band.) may need replacement. A tacky film
that will not wipe clean indicates varnish bulld
up which can cause valves, servo, and clutches
to stick and may inhibit pump pressure.

5. Loosen 2nd band servo piston stem lock nut
and tighten piston stem.
If it turns more than
two turns, the band
is worn out.
