    is there any difficulty on starting engine? if it starts is there any idling problems when car is cold or warm? is there any hesitaton when engine is cold and when you try to rev engine in Neutral?is there any delay between N to D or N to R positions? does it lean foward or backward when you shift into D or R?

You need to be sure that auto trans fluid is in good shape and you need to be sure that it is not missing even little amounts. replace the filter too.

then you need dealer to reset transmission computer for you. if it still happens

if these wont cure you must be sure that selenoids inside transmission are in specs(check on factory service manual for resistance values of each coil).

and be sure that there are no loose electrical connections on transmissions especially a loose ground.

if it shift correctly there may not be a need of overhauling

Where is the speed sensor located on a 2002 Chrysler Concorde

Beware speed sensors seldom fail. Chrysler products transmission have a limp mode where they only shift to second gear when something goes wrong and many times when nothing is wrong. If the speedometer fails it goes to limp. If an OBD scan gives a transmission code sometimes clearing the code will end the problem. When driving if the transmission shifts one time as it should the sensor is working.

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!!!

2000 300m shifts into 2nd gear and locks out all other gears. (limp mode) Changed speed odometer sensor, and have pulled #11 fuse, Checked wiring. battery cables removed for re~set. What else can be...

you replaced the output speed sensor, try replacing the input speed sensor, sometimes called the turbine speed sensor, thats where the computer gets the info to shift.

Wut is a po700 code on a 2004 doge intreped and how do i fix it

The codes mean P0700 Transmission control system malfunction. Unless you've had an automatic transmission apart before I don't recommend it to do it yourselfers. Better to get a professional opinion and avoid really messing it up. That solenoid is part of the valve body and replacing the valve body requires special tools and a bit of expertise. good luck,

The 700 is the limp mode, as I recall. One or both of the sensors are failing, and they are not too expensive to replace. Once replaced, then using the OBD tool, you can delete the fault codes and then be able to shift into all the gears.
I have written about this solution in other blogged questions, and so have others. Under the car, on the Driver side of the transmission are two electric sensors. They lay horizontally on the trans just behind where your foot would go on the accelerator and under the floorboard. The electricl clip sockets pull out with thumb pressure on each socket. DO NOT pull on the wires EVER. Unplug each socket, and replace one at a time. Use a 1" deep well socket and unscrew them from the side of the trans casing. Do one at a time starting with the one on the left, the Input side,; Then the output side.
The reason why I replace them both is that they are cheap- about $20 apiece- and REALLY: do you want to go under there twice for twenty bucks? If so, then just replace the one on the LEFT- the Input sensor. You then MUST RESET THE CODES with the OBD tool for the transmission side of the tool, then GO!

2002 Chrysler 300m transmission goes into "Limp-mode"

2002 has a known solenoid problem. The solenoid pack must be a new type. They have dates printed on them. make sure it has a date after 2003.

Chrysler concorde doesn't shift out of first

It sounds like it is in limp mode, this means that there is a transmission problem. The trans will go into limp mode to protect from further damage. You need to take it to a trans shop to have diagnostic test

1991 bmw 520i transmission goes into 'safe' mode

quoted from
" Transmission locks in "limp" mode - 3rd gear so you can "limp" home or to your nearest dealer."

"Things to check before even contemplating a transmission overhaul:
Check electrics - Alternator and battery.
Replace DME Relay and Fuel Pump Relay - not expensive.
Remove disassemble, clean and reassemble gear selector switch - If it looks beyond saving, replace ($200)
Service the transmission ($130 from a specialist) and check/replace transmission speed sensor ($90)"

you need to get the diagnostic codes to determine why its in 2nd gear (limp-in). it can be numerous things..anything from a input or output speed sensor to a serious internal trans problem.

Have a scan done on your car and have whoever scan the trans. computer. The trans. computer is detecting a problem with one of the sensors and puts the car into "limp in" mode. I positive that you don't need a new trans. It could be a 10 min. fix just a matter of unscrewing a sensor and screwing another one in. I've seen alot of problems with speed sensors, input, and output sensors. Have a scan done though because you don't want to just "throw" parts at it. Go to a shop that has an actual scanner and not a "code reader" like the part stores.
