Was condition found and corrected?
Go to Step 6—
61. After the repair is complete, use the scan tool to select “DTC”,
then “Clear info” function.
2. Operate the vehicle under the following conditions:
Drive the vehicle in D4 with the engine speed greater than
3,500 rpm to obtain anyone of the following gear ratios for
seven seconds.
1st 1:2.73 – 1:2.99

TRANSMISSION CONTROL SYSTEM (4L30–E)7A1–71
DTC P1860 TCC Solenoid Electrical
D07RW010
Circuit Description
The PCM allows current to flow through the solenoid coil
according to the duty cycle (percentage of “on” and “off”
time). This current flow through the solenoid coil creates
a magnetic field that magnetizes the solid core. The
magnetized core attracts the check ball to seat against
spring pressure. This blocks the exhaust for the TCC
signal fluid and allows 2–3 drive fluid to feed to TCC signal
circuit. The TCC signal fluid pressure acts on the TCC
regulator valve to regulate line pressure and to apply fluid
pressure to the torque converter clutch shift valve. When
the TCC shift valve is in the apply position, regulated
apply fluid pressure is directed through the TCC valve to
apply the torque converter clutch. The TCC solenoid is
used in conjunction with the TCC solenoid to regulate fluid
to the torque converter. The TCC solenoid is attached to
the valve body within the transmission.
This DTC detects a continuous open or short to ground or
ignition in the TCC circuit or the TCC solenoid. This is a
type “D” DTC.
Conditions For Setting The DTC
Battery voltage is between 10 and 16 volts.
No shift solenoid A DTC P0753.
No shift solenoid B DTC P0758.
Ignition is “on”, Engine “run”.
The PCM commands the solenoid “on” and the
voltage remains low (zero volts).
The PCM commands the solenoid “off” and the
voltage remains high (B+).
All conditions met for 0.25 seconds.
Action Taken When The DTC Sets
Inhibit TCC engagement.
The PCM will not illuminate the CHECK TRANS
Lamp.
Conditions For Clearing The MIL/DTC
The DTC can be cleared from the PCM history by
using a scan tool.
The DTC will be cleared from history when the vehicle
has achieved 40 warmup cycles without a failure
reported.
The PCM will cancel the DTC default actions when
the fault no longer exists and the ignition is cycled “off”
long enough to power down the PCM.
Diagnostic Aids
Inspect the wiring for poor electrical connections at
the PCM and at the transmission 16–way connector.
Look for possible bent, backed out, deformed or
damaged terminals. Check for weak terminal tension
as we ll. A lso ch eck fo r a ch af e d w ire th at cou l d s ho r t
to bare metal or other wiring. Inspect for a broken wire
inside the insulation.
When diagnosing for a possible intermittent short or
open condition, move the wiring harness while
observing test equipment for a change.
Test Description
The numbers below refer to the step numbers on the
diagnostic chart:
3. This test checks for voltage to the solenoid.
4. This test checks the ability of the PCM and wiring to
control the ignition circuit.
9. This test checks the resistance of the TCC solenoid
and the internal wiring harness.

29. Use the clutch release bearing remover
5–8840–2291–0 (J–39207) to disconnect the clutch
release bearing from the clutch pressure plate.

Release bearing disconnection
1. Pull the shift fork toward the transmission to press
the clutch release bearing against the clutch.
2. Insert the clutch release bearing remover
between the wedge collar and the release
bearing.3. Turn the remover to separate the release bearing.
NOTE: Be sure not to insert the remover between the
wedge collar and the clutch.

31. Remove the transmission assembly with transfer
case from the vehicle.
NOTE: Remove the transfer case from the transmission
assembly if the transmission disassembly required.
Refer to Transfer Case in Drive Line/Axle section.
Installation
1. Apply a thin coat of molybdenum disulfide grease to
the top gear shaft spline.
2. Slowly operate the transmission jack until the front of
transmission is aligned with the rear of the engine.
The slope of the engine and the transmission must be
the same.
3. Align the top gear shaft spline with the clutch driven
plate spline.

5. Apply a force of about 113N (26 Ib) to the tip of the
shift fork in the direction of the transmission to engage
the clutch pressure plate and release bearing.
NOTE: A clicking sound is heard when the release
bearing and the tip of the diaphragm spring engage each
other.
Check to see if they are securely engaged by pushing the
tip of the shift fork toward the engine while applying a
force of about 25 N (5.5 lb). If the shift fork will not move,
then they are securely engaged.
