TCM universal remote control tcm 231456

on newer cards the TCM was moved inside the ECU and forms what is called a PCM,
TCM= the transmission brain for all electronic shifted A/T
the shop manual covers all this. buy one? rent it ?
no engine told (USA CAR) and engines are matched up to A/T transmissions by torque, rating;
so no transmission told either. but solved by me (USA only answers me)
here is the choices seen at CHebby OEM.
had 8 different , v6's then all 3.6Liter if still stock is it? not flex?
it was./
6-Speed Automatic Transmission Assembly - GM (19332871) OEM GM 6-Speed Automatic Transmission Assembly For 2012 Chevrolet Impala
so next where is the brain here TCM ( by any name)
zero hits at chevy for TCM) ECM yes, BCM yes.
seen here and CHEVY does not sell he TCM (neat) read on. why.

are you getting USA OBD2 scan errors for TCM?

now I read your FSM factory service manual to you.
Transmission - 6T70/6T75 TCm words are there,

In the engine compartment, left front lower, inside the front of the automatic transmission, part of the control solenoid valve assembly
states
Control Solenoid (W/Body and TCM) Valve Assembly
ok super deep in the manual here it is (drum rolllllllllll)_

The control solenoid (w/body and TCM) valve assembly contains the following components:

• Transmission control module?(TCM)
• Clutch pressure control solenoids?(Clutch PC Sol)
• Shift solenoids?(SS)
• Line pressure control solenoid?(Line PC Sol)
• Torque converter clutch pressure control solenoid?(TCC?PC Sol)
• Transmission fluid temperature sensor?(TFT Sensor)
• TCM temperature sensor
• Power-up temperature sensor
• Transmission fluid pressure switches?(TFP Sw)

SOLVED !!!
These components are not serviced separately. The control solenoid (w/body and TCM) valve assembly utilizes a lead-frame system to connect these components electrically to the TCM. No wires are used for these components. The control solenoid (w/body and TCM) valve assembly bolts directly to the lower and upper valve body assemblies inside the transmission. The control solenoid (w/body and TCM) valve assembly connects to the engine harness 20-way connector.

end easter egg hunt again.
no problems told at all.
and we all knows A/T box love problems and are mostly very costly cures.
it's in this mess. and not sold as sub parts TCM



SOLVED , TCM is inside here, must buy all see there, as 1.

DTC P0700: Transmission Control Module (TCM) Requested MIL Illumination
The transmission control module (TCM) uses the (GMLAN) to signal the engine control module (ECM) that the TCM is requesting malfunction indicator lamp (MIL) illumination. This happens when the TCM has determined that a failure affecting emissions has occurred in transmission control system. When the ECM receives the message from the TCM, DTC P0700 will set.
DTC P0700 can not be cleared from the ECM until the related TCM codes have been cleared.
This is something best left to a qualified repair shop , doesn't need to be the dealer ! AMMCO could fix it . This code is telling that other codes are stored in the transmission control module . Need a professional type or factory scan tool to check these . As to how much it will cost , no telling without knowing the codes in the TCM !

TCM ? transmission control module ? Did you have it programmed ? Reprogram the TCM. Refer to Control Module References for programming and setup information.
Transmission Control Module Programming and Setup
The transmission control module (TCM) must be programmed with the proper software/calibrations. Ensure that the following conditions exist in order to prepare for TCM programming:
• The battery is fully charged.
• The ignition switch is in the RUN position.
• The Techline equipment cable connection at the data link connector (DLC) is secure.
Program the TCM using the latest software matching the vehicle. Refer to up-to-date Techline equipment user instructions.
If the TCM fails to program, proceed as follows:
3.1. Ensure that the TCM connection is OK.
3.2. Inspect the Techline equipment for the latest software version.
3.3. Attempt to program the TCM. If the TCM still cannot be programmed properly, replace the TCM.

DTC P0700: Transmission Control Module (TCM) Requested MIL Illumination
DTC P0700 can not be cleared from the ECM until the related TCM codes have been cleared.

You don't say which engine your's has ! Or which transmission .
Automatic Transmission - 4L60-E/4L65-E/4L70-E

You need to have TCM checked for codes .

Because it is not starting, you should replace the Crankshaft sensor (above the oil filter, back of the engine)-it will cause a P0700-I have a 99 SL2, 178,000 miles


DTC) CODE # P0700....Transmission Control System (MIL Request) Translation: Transmission Control Module (TCM) Malfunction or Failure. P0700 Information Code The Transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. If any malfunction is detected, the TCM informs the PCM by sending a signal (P0700 code). P0700 means that a code has been set in the TCM. This code is for information ONLY. If this code is present, check for transaxle codes. So basically, the P0700 code is telling you to check the TCM for a transaxle DTC. The TCM can not turn on the check engine light so it has the PCM do it. The dealer probably saw the code P0700 and went to the TCM and pulled out the code stored there telling them the Transmission Solenoid Assembly (TSA) is bad. This is a good example of understanding what the codes actually mean. If the manual you looked at said the TCM is bad and to replace the TCM when you see a P0700, then it is wrong.

Sounds like you may have fried the tcm I would go to car-parts.com and get a good used one. You could check and see if there is any fuses that you blew out that control the tcm if you have a manual for the car you can look at a wiring diagram and find out what fuses are associated with the tcm if not check them all.

It means that it didn't receive a signal from the transmision module.
Have your transmission control module checked.

To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.
