CAUSE•The circuit which is the cause is basically the same as for No.9 “Abnormal shifting”. However, a
malfunction of input signal to TP sensor, input/turbine speed sensor, VSS (including the sensor ground,
sensor harness and connector), or clutch slippage (clutch stuck, low pressure in line) may also be the
cause.
Note
•Before following troubleshooting steps, make sure that the Automatic Transaxle On-Board
Diagnostic and Automatic Transaxle Basic Inspection are conducted.

Diagnostic procedure
11 Shift point is high or low
DESCRIPTION•Shift point considerably different from automatic shift diagram.
•Shift delays when accelerating.
•Shift occurs quickly when accelerating and engine speed does not increase.
POSSIBLE
CAUSE•If the transaxle does not shift abnormally, there is a malfunction of input signal to TP sensor, input/

CAUSE•Basically, TCC does not operate when fail-safe is operating. Verify DTC at first. If TCC operates when
driving at high speeds only, the malfunction (improper adjustment) is in D and/or M ranges switch circuit
or TR switch circuit.
Note
•If the TCC or piston is stuck, inspect them. In addition, inspect the oil cooler for foreign particles
which may have mixed in with the ATF.
•TCC piston slipped, burned
—Line pressure low
