Judgment by measuring line pressure
If line pressure does not rise, first check to make
sure that vacuum
hose is connected properly.
1) When line pressure is low at all positions, the
problem may be due to
Wear on interior of oil pump
Oil leakage at or around oil pump, control
valve body, transmission case or governor
Sticking pressure regulator valve
Sticking pressure modifier valve
2) When line pressure is low at a particular posi-
tion, the problem may be due to the following
If oil leaks at or around forward clutch (rear)
or governor, line pressure
is low in "D", "2" or
"1" range but is normal in "R" range.
If oil leaks at or around low and reverse brake
circuit, line pressure becomes low in
"R" or
"P" range but IS normal in "D", "2" or "1"
range.
3) When line pressure is high, pressure regulator
valve may have stuck
Cutdown point
The cut-down point indicates
a point where line
pressure changes from high to low value.
Before proceeding cut-down testing, make sure
that line pressure "At Idle" and "At
Stall'' is
normal

Sticking pressure modifier valve
Sticking governor valve
Oil leaks at oil passage
(2) When cut-down point is too low or too high,
the problem may be due to
Incorrect springs (at pressure modifier valve
or governor valve)
Oil leaks at oil passage
may be due to
