• Death or injury to the driver / or passenger(s) of the vehicle or other people, if the vehicle has been improperly
repaired.
CAUTION Defined
A CAUTION statement immediately precedes an operating procedure or maintenance practice which, if not correctly
followed, could result in damage to or destruction of equipment, or corruption of data. If a CAUTION statement is ignored,
the following consequences may occur:
• Damage to the vehicle,
• Unnecessary vehicle repairs or component replacement,
• Faulty operation or performance of any system or component being repaired,
• Damage to any system or components which depend on the proper operation of the system or component being
repaired,
• Faulty operation or performance of any systems or components which depend on the proper operation or
performance of the system or component under repair,
• Damage to fasteners, basic tools or special tools and / or
• Leakage of coolant, lubricant or other vital fluids.
NOTE Defined
A NOTE statement immediately precedes or follows an operating procedure, maintenance practice or condition that
requires highlighting. A NOTE statement also emphasises necessary characteristics of a diagnostic or repair procedure.
A NOTE statement is designed to:
• Clarify a procedure,
• Present additional information for accomplishing a procedure,

Automatic Transmission – 4L60E – Electrical Diagnosis Page 7C2–8
1 General Information
1.1 Introduction
This Section covers the electrical diagnostic for the 4L60E automatic transmission when mated to a V6 engine.
1.2 General Description
The 4L60E automatic transmission incorporates electronic controls that utilise a transmission control module (TCM) to
control shift points through:
• the 1-2 and 2-3 shift solenoid valves,
• the 3-2 downshift solenoid valve,
• a torque converter clutch (TCC) solenoid valve,
• apply and release through the TCC pulse width modulated (PW M) solenoid valve, and
• line pressure through the pressure control (PC) solenoid valve.
Electrical signals from various sensors provide information to the TCM about the following:
• vehicle speed,
• throttle position,
• engine coolant temperature,
• transmission fluid temperature,
• gear range selector position,
• engine speed,
• converter turbine speed, and
• engine load braking and operating mode.
The TCM uses this information to determine the precise moment to upshift or downshift, apply or release the TCC and
what fluid pressure is needed to apply the clutches. This type of control provides consistent and precise shift points and
shift quality based on the operating conditions of the vehicle.
Figure 7C2 – 1 shows the location of the internal electronic components in the transmission.
