Question about 2001 Chrysler 300M

1 Answer

300m special Code P0700

I have this code pop up irregularly but seems to happen when car is downshifting, It goes into 2nd gear "limp home" mode and all other gears including auto stick are disabled. I can shut the car off and it starts and runs normally until the downshift happens again. It seems to happen less frequently while slowing down very slowly. I've changed the input and output speed sensors, the solenoid valve assembly, and had the trans fluid and filter changed/serviced. It seems I've done all the common failures that cause this. What else can it be?

    Can anybody tell me where the TCM for the 1999 300M is located? Do I need the dealer to test the Mod?

This is what sets the code.

Engine started, engine running, and the PCM received a message over the CCD bus from the Transmission Control Module (TCM) that it had detected a problem and set a trouble code in memory. This code sets in 1 Trip(s).
The presence of this code means the TCM detected a problem. TCM related sensor is damaged or has failed.

After everything you have done I would recommend taking it to a transmission shop, I'm sure they have seen this on Chryslers. and know what the common problems are.

The transmission started downshifting into 2nd gear and staying there until it's turned off & re-started. How hard is the trans solenoid to change? What else might need to be checked or changed?


P0700 is just the TCM telling the PCM to turn on the check engine light because it sensed a problem in the transmission. The code P1776 is most likely a complete valve body replacement issue, About $1000.00 for parts and fluid will be about $25 plug a filter and gasket about $25 more. Before you do anything have this professionally diagnosed, don't guess, which is what I am doing..

04 Chrysler 300m goes into limp mode only when the A/C is on? i get P0700 and P1776 codes


P0700 is a general fault code for the transmission. P1776 is a fault code for the low/reverse solenoid inside the transmission. Since your problem is only present while the A/C is on, it is most likely electrical. Check your battery charge and your alternator performance FIRST, as either of these can cause this problem. Check the wiring to the solenoid, which is located at the front of the transmission. Finally, change the transmission control relay located inside the power distribution box ("fuse box") under the hood.

My dodge caravan 3.3L shows 5 malfunction codes what do they mean po455 po846 po500 po700 po732


P0455 = Evap leak monitor large leak detected.
This code usually means the gas cap may have been loose or needs the rubber gasket.

P0500 = No vehicle speed sensor signal.
Vehicle speed sensor is located on the transmission near one of the axle shafts (it may need replacing).

P0700 = EATX controller DTC present.
This simply means you have transmission related codes.

P0732 = Gear ratio error in 2nd gear.
This code is of some concern, it means the transmission is slipping in 2nd gear. However the trans may be in limp mode due to the speed sensor code (limp mode means the trans starts out in second gear in order to at least get to a mechanic). The first thing I would do is have these codes cleared as there may be absolutely nothing wrong with the transmission (especially if you pull the trans dip stick and the fluid does not have a burnt smell. The vehicle should drive normally after that. If the check engine light comes back, have the codes scanned ASAP (before any other unrelated code sets). Chances are it may be the output speed sensor if this happens (easy fix). Hope this helps

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.

I was driving my 2004 300m tonight and as I came to a red light I cruised into the intersection at about 40mph. My car then downshifted on its own (automatic trans.) into the gear just below the gear I...


Are you throwing any codes? Sounds like limp mode.

Do the key dance to see if you have any codes:

Key in ignition;

Cycle On, off, on, off, on, without cranking it.

If you get P0700 you have the Generic transmission fault code, could range from the TCM to minor\major transmission problems.

1996 gmc jimmy will not shift to 3rd gear


Hi, It may be in LIMP 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.

Common failures on 4L60E, symptom any possible repair:

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 :ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Car goes into gear but feels very sluggish like the brakes are dragging, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Trans seems noisy when moving in 1st and Reverse, noise goes away instantly if you shift to N or the trans goes into 3rd gear: Reaction planetary is worn out due to high miles or insufficient lubrication. Not a critical failure, but not a good sign either. R&R sooner rather than later.

3rd gear starts, can manually shift through all gears. When car has been turned off for a bit, then back on it will run normally.: VSS dropoff w/ Hi-stall converter. The rpms are too high, but VSS is showing no movement. Happens after a tire burning take-off. Doesn't store a code, will not throw a CEL (I've heard that it will store a code if it happens 3 or more times). Cure: Reprogram PCM for VSS dropoff -- PCMforLess knows about it.

If you can get the Jimmy for no more then $500.00 and the engine sounds good and body is good, you may want to invest in the repair of the jimmy. Also note that to have a close look at the fuel line along the frame on the drivers side just by the back doors, the line is know to corroded there on all the SUV's

1996 gmc jimmy won`t shift from 1st to 2nd


IF the abs dash light is on and if the speedometer is sluggish or not working at all, it is probably a bad speed sensor on the transmission. and easy fix under $40 for the part. Mine was stuck in second gear for a while then worked then it stuck in first gear and i had the CHECK ENGINE light on.

Car wont shift from 2nd gear and speedometer doesnt work. diagnostic code p0700. what does this mean?


the PO700 code is a generic transmission code. You would need access to a proper scan tool to check for transmission codes. However if you speedo isnt working, it sounds as though you have a bad output speed sensor. This part runs about 60.00 from the dealer, and is fairly easy to install. No speed signal will put the transmission into limp mode, and keep it stuck in 2nd gear.
