I replaced the TCM in my 2005 Chevy colbolt, light come on but car won't start, turn key and anti theft icon comes on but doesn't stay on


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.

New 30rh transmission was installed in my 97 4.0l jeep wrangler and it shifts in all gears except for 3rd! even when it downshifts it goes through all gears but 3rd? please help


why not ask installer that.
btw , the TCM can fail and do that.
that is either a separate module or part of the PCM.

The TCM does all shifting. electronic, shifting it is.
the TCM has scan code errors, did you scan it and the PCM for errors.
if not , why not.????
2>3 shift failure.

even a loose or corroded , trans wired connector can fail.
or the tranny ground strap is missing.
saw a guy replace a tranny 3 times. and all 3 times failed.
he never knew the trans must be grounded perfectly .
his was missing, others simply broken, others rotted away.

what we do is make sure the TCM is sending the correct
voltage single 0v.12v, etc. to the transmission solenoids.
if not, the TCM is bad, or is in limphome. or inputs wrong.

TCM have what is called limphome that can skip gears.
my 4speed skips 2nd , in limp, by DESIGN !
all this is covered in the FSM, why not read it.
or look at alldata.com it's there too.

i also have a switch box, i made., that attaches to the tranny
allowing me to make a manual transmission,
if that works the tranny is good.

the TCM will in fact mess up if its inputs are wrong
just like all computers do.
inputs are, TPS, VSS1 , VSS2, engine heat. shift selector switch PRNDL , and others.
The TCM shifts by the state of inputs. period

one cool thing, some cars pre 98, or so
the TCM is separate box. and with it unplugged
the shifter is now a manual transmission car. (for test or?)
have friends driving like this for 3 years.

Put trans in works great but has a code po 0700


P0700 is a generic fault code indicating a transmission problem. It's possible it's a left over code from the bad transmission you replaced. You may need to have the code cleared at a transmission shop that uses a different code reader to clear the code. Unfortunately, unlike the standard OBDII code reader, the transmission codes don't always reset themselves after a repair is made.

What is tcm internal memory error. Check engine came on. Code is p0605


Transmission Control module; It is monitored when the ignition key is on. In short, the software has failed and does not match a calculated value. This is an internal fault that requires TCM replacement.

Car does not run ,I check the code ,it is P0700


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.

P0700, P0750 and P0755 codes I was driving at 65 mph and the 2003 Dodge Caravan down shifter to low gear and the check engine light came on. It will not ship to high gear.


P0700 (M)
Check Transmission DTC's
This code indicates that the EATX (Transmission controller) has an active fault and has illuminated the MIL via a BUS message. The specific fault must be acquired from the EATX via a DRBIII tool. (Input or Output Speed Sensor failures often cause this code and are a common failure part on WJ Grand Cherokees

P0750
Shift Solenoid circuit.
Note: If code P1767 (Transmission Relay Always On) is also present: Replace transmission solenoid assembly. See note provided. When transmission is in limp mode the relay that provides power to the solenoid group is switched off. This is normal and is designed to provide operation in one gear only. Engineering department suggests to replace transmission solenoid assembly anytime these two trouble codes occur together. See applicable service manual section (21) for solenoid assembly replacement directions. IMPORTANT: When performing this repair always check torque on all valvebody accumulator cover plate screws. Proper torque specification is 70 inch pounds. If any accumulator cover plate screws are damaged or missing replace the valvebody assembly. NOTE: If any other trouble codes are present do not replace solenoid assembly. See test in the applicable Transmission Diagnostic Procedures Manual

P0755
Shift Solenoid B
