Theory of Operation
The 3-4 Solenoid is used the engage the gear change from 3rd gear to 4th gear.
The solenoids used in transmission applications are attached to valves which can be classified as normally open or
normally closed. The normally open solenoid valve is defined as a valve which allows hydraulic flow when no cur-
rent or voltage is applied to the solenoid. The normally closed solenoid valve is defined as a valve which does not
allow hydraulic flow when no current or voltage is applied to the solenoid.These valves perform hydraulic control
functions for the transmission and must therefore be durable and tolerantof dirt particles. For these reasons, the
valves have hardened steel poppets and ball valves. The solenoids operatethe valves directly, which means that
the solenoids must have very high outputs to close the valves against the sizable flow areas and line pressures
found in current transmissions. Fastresponse time is also necessary to ensure accurate control.
When Monitored:
Continuously with ignition on.
Set Condition:
This code will set if the voltage detected on the 3-4 Shift Solenoid Controlcircuit at the ECM is different then
the expected voltage. Note: To clear this DTC it is necessary to drive the vehicle at a sustained speed which
would allow the TCC and/or Overdrive Clutch to operate

Theory of Operation
The transmission throttle valve cable has been replace by the transmission throttle valve actuator (TTVA). The TTVA
consists of an electric DC motor, two potentiometers, and a gear drive system. The TTVA is mechanically connected
to the transmission throttle valve in the valve body by the “D” shaped opening in the bottom of the TTVA shaft.
The Transmission Throttle Valve Actuator (TTVA) does not require any mechanical adjustments. All changes in throt-
tle valve position are controlled by the Engine Control Module (ECM).
The TTVA does require an initialization period after the actuator has beenremoved or replaced. After the actuator
has been removed or replaced, move the ignition to the ON position for thirty (30) seconds. This will allow the ECM
sufficient time to perform the internal calibration procedures to learn the TTVA’s current “zero” position.
When Monitored:
Continuously with the ignition on.
Set Condition:
When the Engine Control Module (ECM) detects the monitored Transmission Throttle Valve Position Sensor
voltage drops below a predetermined value.
Possible Causes

When Monitored:
Ignition on and with or without engine running with transmission in the park or neutral position. Note: Not mon-
itored when either the engine is cranking or while vehicle is moving.
Set Condition:
Each time the ignition is cycled to the on position, the ECM commands a TTVA internal calibration procedure
(autozero) to determine the zero position. If the TTVA does not reach a calibrated minimum position in a pre-
determined amount of time, the DTC will set.
