TCM Replacement?

Regardless if it is or not it would need to be programmed to your car anyhow so it would not matter.

If you change it it could change shift points.

Get it scanned for codes by a trans guy because the wiring may be screwed upor grounding out someplace or it's an internal trans problem.

It cold be wiring issue inside or out of trans, another bad sensor etc. Or it could be a trans problem all together.

It most certainly does and you don't have the proper tools. You better take it to the Jaguar dealer and see if they can program it, and maybe non-compatible depending on how many components you need with the computer you replace

I have the complete manual on this car but it is very extensive, I'm sending you the fuel section in trying to find the programming section, let me know what sections you want me to send you.

Fuel System 2.5L and 3.0L vehicles Fig. 30: Fuel System Components (2.5L And 3.0L) Courtesy of JAGUAR CARS, INC. The electronic returnless fuel system utilized has the following advantages: reduced fuel tank vapor. Requires less electrical power. Does not require a fuel return line. The intelligence of this system is contained within the engine control module (ECM). The ECM determines the required fuel flow and communicates this information to the fuel pump controller. The fuel pump controller has the fuel pump driver functions fully integrated into the microprocessor. The ECM calculates the frequency and determines the current required by the fuel pump to maintain the correct fuel pressure at the fuel injectors. The fuel tank is of a saddle design which incorporates two sender units. The right-hand side houses the fuel pump module. The left-hand side houses the transfer pump module. CAUTION:The use of supplementary oil or fuel additives is not approved unless specified by Jaguar Cars in the form of a service communication or directive. Fuel is supplied at high pressure to the injectors via a fuel rail which incorporates a fuel pressure and a fuel temperature sensor. The ECM increases the fuel pressure to minimize fuel vapor formation to maintain fuel flow across the injectors. An inertia type fuel cut-off switch will cut power to the fuel pump module in the event of an accident.

Diagnosis and Testing Fuel System Verify the customer concern. Visually inspect for obvious signs of mechanical or electrical damage. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. If the concern is not visually evident, refer to the Symptom Chart.

JAGUAR PRINCIPLES OF OPERATION
Newly released modules require configuration after being installed on the vehicle. All configurable modules will be packaged in a kit which contains a warning label and a multi-language sheet reemphasizing requirements to configure replacement modules. Powertrain Control Module (PCM) has to be standard J1962 lead. MODULE CONFIGURATION There are two modes of configuration data. First type requires configuration information so that module can interact with vehicle correctly. This information will be transferred into new module so that new module will contain same settings as old module. Modules on vehicle that require configuration when installing a replacement module are:

Anti-lock brake control module with traction control.
Anti-lock brake control module with traction control and dynamitic stability control.
Remote keyless entry driver door module.
Steering lock control module.
Driver seat module.
Audio control module.
Vehicle emergency message system/Jaguar assist.
Dual automatic temperature control.
Instrument cluster with message center.
Rear electronic module.
General electronic module.
To carry out configuration process, upload old information from old module using PDU (if applicable).
Install new module. For additional information on the anti-lock brake control module, appropriate ANTI-LOCK article in BRAKES. For additional information on the DDM, see appropriate POWER DOOR LOCK article in ACCESSORIES & EQUIPMENT. For additional information on the instrument cluster, see appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. For additional information on the GEM and the REM, appropriate BODY CONTROL MODULES article in ACCESSORIES & EQUIPMENT. PDU will not retain stored configuration information for longer than 24 hours. Download stored information into new module using PDU (if applicable).

POWERTRAIN CONTROL MODULE PROGRAMMING S-Type If battery has been disconnected, engine should be allowed to idle for three minutes as stored idle and drive values contained within PCM have been lost. This may cause a driveability concern if following procedure is not carried out. Once the engine reaches normal operating temperature, engine speed should be increased to 1200 RPM and maintained for approximately two minutes. This will allow PCM to relearn idle values. For PCM to complete it's learning strategy, the vehicle should be driven for approximately 5 miles of varied driving. X-Type If battery has been disconnected, engine should be allowed to idle until it has reached normal operating temperature as stored idle and drive values contained within the PCM have been lost. Allow vehicle to idle for a further three minutes. Drive vehicle at constant speeds of approximately 30, 40, 50, 60 and 70 mph for three minutes each. This will allow PCM to relearn idle values. Driveability concern may exist if procedure is not carried out.

REMOTE KEYLESS ENTRY TRANSMITTER NOTE:All remote transmitters are programmable and must be set at the same time. If an attempt is made to program a fifth remote entry device after four remote entry devices have already been programmed, the attempt shall erase all remote entry device associations and start a new set of four remote entry device associations with fifth remote device programming attempt. Programming (or reprogram) of remote transmitters into remote keyless entry Driver Door Module (DDM) is carried out with PDU. Due to complexity of the electronics involved with the remote keyless entry, of which the DDM is a part, and the multiplexed communication network which are connected to it preclude the use of general electrical test equipment. Therefore, reference should be made to the PDU User Guide for detailed instructions on programming the remote transmitters. TRANSMISSION CONTROL MODULE DRIVEABILITY COMPUTER RELEARN PROCEDURE Manufacturer does not provide a specific computer relearn procedure for obtaining proper driveability. If vehicle battery was disconnected or TCM was replaced, driving the vehicle will enable the TCM to perform a computer relearn procedure for obtaining proper driveability. Inform customer that driveability may differ from what they are accustomed to until the TCM completes the computer relearn procedure.
