7A2-140 TRANSMISSION CONTROL SYSTEM (JR405E)
• Electrically Erasable Programmable Read OnlyMemory (EEPROM)
This type of memory allows selected portions of
memory to be programmed while other portions
remain unchanged.
Certain learned values reside in the EEPROM,
such as:
- The vehicle identification number (VIN)
- The software/ calibrations identification numbers
- The control module security information
• Flash Read Only Memory-Flash Memory
Flash memory has increased memory storage capacity.
During programming, all information within this type of
memory is erased, and then replaced with entirely new
information.
Service Programming Methods
The two methods of programming a TCM are listed
below:
• Remote Programming
• Pass Thru Programming
For information on programming a TCM using one of
the methods listed above, refer to Service
Programming System (SPS) (Remote Procedure) or
Service Programming System (SPS) (Pass-Thru
Procedure).
Before Programming a Control Module
Important: DO NOT program an existing TCM with the
identical software/ calibration package. This procedure
is not a short cut to correct the driveability condition.
This is an ineffective repair. An TCM should only be
programmed when the following occurs:
• When a service procedure instructs you to replace the TCM.
• An updated software/ calibrations is released.
Ensure that the following conditions are met before
programming a TCM:
• The scan tool PCMCIA card is programmed with the latest software.
• The TIS 2000 is installed with the latest software.
• The hardware key is plugged into the computer port.
• Vehicle system voltage:
- There are no charging system concerns. Allcharging system concerns must be repaired
before programming the TCM.
- The battery voltage is greater than 12 volts but less than 16 volts. The battery must be fully
charged before programming the TCM.
- A battery charger is NOT connected to the vehicles battery. Incorrect system voltage or
voltage fluctuations from a battery charger may
cause programming failure or TCM damage. - Turn OFF or disable any system that may put a
load on the vehicles battery. Turn OFF or
disable systems such as:
◊ Heating, ventilation, and air conditioning
(HVAC) systems
◊ Headlights
◊ Room lights
◊ Accessory equipment
• The ignition switch is in the proper position. The scan tool prompts you to turn ON the ignition, with
the engine OFF. DO NOT change the position of
the ignition switch during the programming
procedure unless instructed to do so.
• All tool connections are secure:
- The RS-232 cable
- The connection at the DLC
- The voltage supply circuits
• DO NOT disturb the tool harnesses while programming. If an interruption occurs during the
programming procedure, programming failure or
TCM damage may occur.
• If you are performing the Pass-Thru programming procedure using a notebook computer without the
power cord, ensure that the internal battery is fully
charged.
Service Programming System (SPS)
(Remote Procedure)
Notice: Some module will not accept SPS remote
procedure using 10MB PCMCIA card. In such case,
use 32MB PCMCIA card or SPS pass-thru procedure.
The Remote SPS method is a three-step process that
involves the following procedures:
1. Connecting the scan tool to the vehicle and obtaining the information from the TCM.
2. Connecting the scan tool to the terminal and downloading a new calibration file from the
terminal into the scan tool memory.
3. Reconnecting the scan tool to the vehicle and uploading the new calibration file into the TCM.
Performing the Remote Procedure 1. Connect a scan tool to the vehicle and obtain the TCM information using the following procedure:
Notice: Ensure the TCM is installed in the vehicle and
the battery is fully charged before programming.
a. Install a scan tool.
b. Turn ON the ignition, with the engine OFF.
c. Select Service Programming System (SPS) > Request Info.

AUTOMATIC TRANSMISSION
DISASSEMBLY
Cleaning the automatic transmission
1. Use compressed steam and /or cleaning oil to thoroughly
clean the outside of the transmission before disassembly.
CAUTION:
Steam under high pressure may cause dirt particles
adhering to the transmission to fly through the air at great
speed. These particles can cause serious eye injury. Wear
protective goggles when steam-cleaning the outside of
the transmission.
2. During disassembly, clean the removed parts with cleaning oil. Dry the parts with compressed air.
Use Compressed air to clean the transmission oil holes
and oil passages.

Automatic transmission disassembly cautions
• Perform the disassembly procedure in a dust-free
environment to prevent the entry of foreign material into
the transmission.
• Inspect each transmission part as you remove it.
• Carefully check the oil pan and the magnet for foreign
material. This is a good way to estimate the transmission
condition.
• Use your bare hands or vinyl gloves to disassemble the
transmission. Do not use ordinary work gloves (loose
threads from the gloves may fall into the transmission and
cause problems).
• Use a plastic hammer to loosen the transmission case
and other aluminum parts during disassembly. Strike
around the parts lightly with the hammer. Do not pry
aluminum parts away from each other with a screwdriver
or similar object.
• Arrange the disassembled parts neatly in the order they
were removed. Cover the parts with a plastic sheet or
similar object to protect them from dust.
