EXCERPT:
4T40E/45E N-Car
Hard Shifts/ No DTC’S
4T40E/45E applications may exhibit a hard shift concern that may/may not be intermittent. In some instances an IAT (intake air temperature sensor) DTC may be set. The PCS commanded/actual amperages will indicate low amperage flow through the PCS and its circuits. In addition the technician may indicate that he/she had problems controlling the PCS amperage when using the PCS override feature on their scan tool.
Several of the 4T40E/45E applications utilize the IAT sensor as part of the engine torque calculations. Torque modeling is used by the PCM to determine the line pressure calculation.
The most common causes of this concern are:
. Broken wiring, generally the wire is damaged at the sensor connector
. Terminal pin tension, terminal crimp damaged
. A faulty IAT sensor

4T40E
Saturn Application
Possible P0731 DTC set
Saturn applications use individual DTCs to identify which gear the transaxle was in at the time a ratio error occurred. P0731 sets if a ratio error occurs in 1st gear while P0732 will set if a ratio error is present in 2nd, P0733 in 3rd and P0734 will set in 4th.
If a P0731 is set along with any or all of the following DTCs, address the other DTCs first. Other DTCs which may effect diagnosis include:
. P0716 (Turbine speed electrical interference/noise)
. P0717 (No turbine signal)
. P0745 (Low line pressure)
. P0722 (No VSS signal).
If only a P0731 is set, review the stored data relating to the DTC and note which shifter position the transaxle was in and the VSS values. If the DTC was set in park and the VSS data indicates a VSS reading (usually around 15-35mph) the cause of the problem is typically a poor ITCM (Internal Transmission Control Module) ground (G115 on the back of the engine).
