1. TEST METHODS

• MPT model
Check the transfer clutch pressure in accordance
with the following chart in the same manner as with
line pressure. <Ref. to AT-36, Line Pressure Test.>

2. EVALUATION

• MPT model

NOTE:
If oil pressure is not produced or if it does not
change in the AWD mode, the transfer duty sole-
noid or transfer valve assembly may be malfunc-
tioning. If oil pressure is produced in the FWD
mode, the problem is similar to that in the AWD
mode.
