    hi thanks for responding. right now there is no low gear because it is in limp mode so there is no difference between low, drive and overdrive. when you shift into reverse everthing is fine. the car does not stall and you would think that everything is good. the idle speed is at about 600 rpms. if you just wanted to start the car wait 20 seconds you can drive all day up to about 40mph. if you start the car and put in reverse you dont have to wait and

    hey all thanks for responding. the speedo works fine and the only fault codes i can get are 12 and 55. as for reverse gear it is normal. i would say it is just the low ratio like 1st gear. the idle is set at 7 to 900 rpms. you would never know anything is wrong with this car until you reach a speed where it should shift and then nothing. ahhhhhhhhhh

    you cannot retrieve trans faults on these vehicles by cycling ignition..must be done with a scan may have an input speed sensor bad or wiring broken going to solenoid pack..have also seen ignition switch not powering up trans controller causing issues

sounds like you have a blown head gasket this would explain loss of coolant and running poorly excessive smoke.

SOURCE: no reverse only drives for 30 seconds limp mode???? please help!

P1388 = Auto Shutdown (ASD) relay control circuit open or shorted.
The ASD relay routes battery power to the ignition coils, and is energized by the PCM as long as it receives signals from both the crankshaft and camshaft position sensors. If the engine stops turning (stalls), the PCM deengerizes the ASD relay and shuts down the ignition system. The ASD relay also supplies battery voltage to the fuel injectors, so when it shuts down it cuts off both ignition and fuel. At the same time, the PCM also deenergizes the fuel pump relay to turn off the fuel pump. For "limp in" capability, the Chrysler system can run with input from the crankshaft position sensor only. The ASD and fuel pump relays are both located in the Power Distribution Center.

SOURCE: possible transmission out not sure

When was the last time you had transmission oil changed and the tranny pan removed and the tranny filter changed? If never, this is your starting point.

The problem with these vans is that the tranny pan is at about a 20 degree angle under the transmission near the driver front tire. The problem with this design is that these pans eventually begin to leak at the lowest point of the pan, and over time you will not notice the ATF loss. Most likely your ATF level or cleanliness/viscosity may be bad.
Don't cry 'TRANSMISSION' until you get your tranny serviced (ATf oilc change, new tranny filter, clean magnets, clean pan, clean tranny).

96 Chrysler concorde 3.5L, I have consistantly pull the gas after start or it won't stay started. As is the pcm forgot the idle. Once its warmed up it will have a rough idle and eventualy die. What...

I have a 1996 LHS, same 3.5L engine, loved the riding and smoothness when i bought it 2 years ago..... F@#$%ng money pit, a POS scam artist of a mechanic charged me 4200 for new front end suspension a year ago which is already shot again, after that i insisted on doing everything on this car myself. As i have no professional training nor do i have a stocked garage this goes without saying is a daunting task.I recommend buying or borrowing(local library) a Chilton and/or Haynes manual. The Chrysler Concorde is the same car different body style as my LHS, a Piece of something.. I'm in the midst of learning about the idling, as i have an opposite problem with too high rpms.

So far, i've concluded that some sensors only malfunction during certain conditions, i.e. cooling temperature sensor that activates fans, also can cause rich or lean fuel/air mixtures. It sounds to me like something is inducing a rich fuel mixture(high rpms) and your PCM (LHS' under air filter compartment) is overcompensating and has stored into its memory leading to a lean running car. I know it doesn't answer your question but hopefully it'll spark an idea. when i figure it out exactly i'll let you know.

Got trouble code p0125. Car starts then idles way low then climbs back to regular idle. What is the problem?

I have a 96 Towncar, which had a P0125 trouble code set. I changed the thermostat and cleared the code - only to have it reset in a couple minutes after starting. The car was hard starting, and died several times before it actually ran. I did also noticed that while running the idle speed had risen to over 950 RPM.

I changed the Temperature sending unit located next to the thermostat housing, and again cleared the code. After starting the car again it performed excellently and did not reset the P0125 trouble code.

95 chrysler lhs transmission problems again

Since this car is over twenty years old and on the market only worth $500.00 in running condition it is not worth putting more money in to it. I feel you have transmission troubles. Because of the low mileage it has been sitting a lot. That alone will cause things to not work.

You have still got air in the system.Remove the Feed back pipe from the header tank and wait for all the air to come out while the engine is running making sure you are toping up the header tank at the same time Dont allow header tank to run dry while doing this.Good luck

BMW 320i trouble in moving the car in D

Start with replacing transmission fluid. They do recommednd Dextron III but usually syntetic oil 5w-30 does this job very well. But grinding sound maybe the sign of transmission problem
You can take it to a qualified shop (I dont know there you are), and had them run the codes for the transmission (OBD I)
