Question about 2003 Chrysler 300M

1 Answer

2003 Chrysler 300 check engine codes p0700 and 1776, car occasionally drops into 2nd gear - limp home mode - and will not shift out. Turning off car corrects the problem for and hour or for days. Does this sound like trans control module?, if so, is that a separate unit on the 2003 or is it part of the pcm, can I just change out the problem module if it is preprogrammed with VIN and miles?

THERE IS A TECHNICAL SERVICE BULLETIN FOR P1776..SOLENOID SWITCH VALVE LATCHED IN THE LOW/REVERSE POSITION..YOU NEED TO HAVE SCANNED AGAIN AND HAVE "EVENT DATA" READ..
LOOKING FOR TRS CODE..IF IT READS TR2,YOU NED TO HAVE TRANS SHIFT CABLE ADJUSTMENT CHECKED AND FOR BINDING AS WELL..IF IT READS OD,VALVE BODY OF TRANS MAY HAVE A STICKING SOLENOID SWITCH VALVE IN VALVE BODY..ALSO IF TRS CODE LEADS YOU TO VALVE BODY ISSUE..YOU NEED TO HAVE SOLENOID PACK BUILD DATE CODE CHECKED..IF IT FALLS IN A CERTAIN DATE,YOU REPLACE THE SOLENOID PACK,NOT THE VALVE BODY..A GOOD TRANS SHOP OR CHRYSLER DEALER WILL BE ABLE TO DIAGNOSE THIS PROBLEM..ALSO TCM IS PART OF PCM ON THIS YEAR VEHICLE AND YOU CANNOT SWAP ONE FROM ANOTHER VEHICLE..BUT I DON'T THINK YOU HAVE A CONTROLLER ISSUE..THE LH VEHICLES I HAVE SEEN WITH THIS PROBLEM THE SOLENOID PACK ON TOP OF THE VALVE BODY IS THE TROUBLE..I WORK AS A CHRYSLER TECH..13 YEARS EXPERIENCE

On my 2006 Chrysler 300, the brake light, check engine light and other minor dash lights are on and the transmission won't shift out of 1st gear. Any idea what's going on?


If a car goes into limp mode, its likely something spectacular has gone wrong and the car is protecting itself from major damage. You will probably have to go to a Chrysler Dealer to rectify and get them to clear the fault off the cars computer.

I have a 1999 Chrysler 300M. Simultaneously, the Check Engine light came on, the speedometer stopped working, and the car doesn't shift out of 2nd gear. What's the likely problem?


these vehicles have alot of problems with the tcm( tranmission control module) internal failures of trans speed sensors. your car is currently in "limp in mode" to protect your trasmission!!!

Changed transmission computer still have code 605 wont shift out of 2nd gear


did you have pinion factor and quick learn performed on the trans module after replacement? if not then the trans won't shift correctly. also is the check engine light on with any engine codes in memory? the engine module may the trans stuck in limp-in mode(2nd gear).

Chrysler 300 downshifted going down highway to 2nd gear.car now only has 2nd and reverse.When you put into drive selector goes directly to 2nd.trans makes no noise but will not shift.at the same time this...


it sounds like the transmission has gone into what they call limp in mode which indicates a problem with the transmission.you will have to have a scan tool put on it to pull the code out of the tcm(transmission control module) which will turn on the engine light.at the same time it may show a code for the temp control.

Starts out in 3rd gear


Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmision is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the underhood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.
What is "limp-home mode" ? This is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.
Before guessing at transmission problems, check the fluid level (car warmed up, engine running in Park on level ground) and have the PCM scanned for trouble codes FIRST. This guide is meant for problems that do not show up as PCM codes (like shift A&B solenoid failures, for example).

4L 60E - 2001 k1500 will not shift into 3-4. Oil is not burn't and stifts great into1-2


  • No 3rd or 4th gear: “3-4” clutches are worn out. R&R. The car is safe to drive (in 2) until you can get it fixed.
  • Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.
  • No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : Shift A solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.
Check to see if your transmission is in the limp mode, which would only give you 2nd, 3rd and reverse gears. No 1st or 4th gear.
