Have a Chrysler Concorde, 2001. I can drive it a little ways and as i begin to slow down most the time I hear a big boom like noise (like a huge balloon, but deeper in sound) and then it stays in 2nd gear I think it is. Will not shift until I pull over and turn off the car and turn it back on. then I can go a ways then it will happen again. It does not make the loud noise every time though. Here is the codes I get taken to auto zone 1776 0731 0155 0135 0700 0036

sounds like the thermostat is stuck open and requires replacing.

You need to check For cooling fan operation. It may be a temp sensor problem (Fan relay signal) or a bad relay. A SIMPLE TEST would be to turn on the A/C, the cooling fan should run continuous in this position. The fan should run intermittently Relative to Coolant Temp. in all other positions. Check for voltage (14v ) at fan motor harness connector . If voltage is present at the fan motor connector then most likely a bad fan motor. The temp switch ( Fan Relay signal) is located in the thermostat housing or the radiator. This engine is prone to head gasket failure so do not overheat during testing procedures.

Cv joint or lower ball joint worn

You have a check light on

What codes have you retrieved?

What testing has been done?

could be cv joint but jack up wheels and move tire up down and left right up down if play check ball joints /anti-sway bar bushings--------if play left to right than check idler arms and steering system /and anti sway bar bushings

White smoke is possibly coolant from a bad head gasket or possibly intake gasket,depending on engine design.

When you say big cloud,I assume the vehicle is warmed up all the way and this happens a lot.

You should check to see if you have coolant in the recovery bottle under the hood,if not or it blows bubbles into it,I wouldn't use the vehicle, even to go around the corner.

It most likely needs to be torn down and repaired, after some initial tests are done.

That sound you hear is coming from the Vauum Brake Booster...Sooner or later the Brake Pedal will get hard, because the seal inside of the Brake Booster is leaking..And the only way to repair it, is , to replace the Brake Booster...But also check your Vacuum Hose that is instaaled on your Brake Booster..It goes from the Brake Booster, which is behind the Master Cylinder...From there to the Intake Manifold...Just make sure that there are no cracks in that hose, and make sure it is on all the way...because if the hose is bad, then thats all you will have to replace....Goodluck...

this is a matter of knowing a little bit about your car, maybe a cv joint but I will gamble a little on the brake pads, when you apply the brakes they move inside the caliper and thats the noise you hear, try it on reverse, if it does the same thing check your blake pads.

Sounds to me like you have a bad thermostat. If you know how to change it you can give it a shot. If you dont know what I'm talking about, take your car in to a mechanic and tell em to have a look at your thermostat.

the whine you hear is the trans pump, chrysler vehicles take a special fluid most atf bottles will say if they are chrysler recommened, there is a additive you can get to
