Code p1818 trans code p1818

the codes are trans codes and the trans will have to be inspected and tested to fix. it may be more than you can handle if so take it to a reputable trans shop.

Code points more towards tranny problem, not TCM. Check tranny fluid level (google instructions; there is no 'dip stick'. You need to fill until if overflows). Also: gear selector (on the side of the tranny).

P0305 - Cylinder number 5 misfire detected.
Probable faults and reasons:
Igniter no. 5 defective.
Ignition system malfunction.
Spark plug is short or its air too wide. (0.9 - 1.1 mm)
Weak compression.
Valve clearance less than recommended.
Engine valves and seats defective.
Fuel pump pressure too high.
P0421 - Warm up catalytic efficiency is below threshold (Bank 1)
Probable faults and reasons:
Catalytic converter.
Heated oxygen Bank 1.sensor 1, 2.
P1818 - Manufacturer specific code.

Start with a tune up and change your fuel filter. Check your plug wires or better, replace them. The p0421 code has to do with the cat. Also, install spark plug anti foulers, you can get them at your local auto parts store. Follow the spark plug link. As for p1818, have this code reset at a reliable shop preferably a transmission shop. Ask around and some of your friends for their recommendations as to where you can take your car to to have the trans control module reset without the shop trying to tell you you have to fix something, ie shell out the big bucks. tell them aLl you want is to have the code and trans reset, NOTHING MORE. Sometimes this code comes up false. so have it reset after you take care of the tune up etc. this code should be reset using a transmission code reader.

This is usually a PCM / TCM problem, replacement, wiring repairs, or reprograming is usually the repair. Dealership is your best option for a qualified Diagnosis /repair.

code p0700 refers to transmission control system malfunction==causes wiring-- TCM= replace the TCM . Check with the dealer to find which servo/ sensor p1818 refers to but it may also be related to the TCM.

not sure but most times inside transmission ...remove pan

782 code is trans is 2-3 shift problem. This is inside the Trans Solenoid. This sits on the trans above the trans pan. $200 part includes gasket

code po700 is to tell the ecm and you there is a trans.problem and dtc set in trans.module. po755 is a trans. shift solenoid problem. check trans.fluid level when hot and color of fluid ,dark is not good,burnt smell not good .chrysler has a large trans.problem need to visit a trans. shop for repairs.hope this helps.

P0700 is a pcm trouble code that basicly says there is more trouble codes in the trans controller side of the pcm.
in order to find out what those codes are you will need a scan tool and then once you have the codes further diagnosis can be done.
depending on what codes come out of the trans controller it could mean something simple like a bad speed sensor or some kinda bad like a loss of prime. gear ratio error codes can be caused by faulty sensors.


Best advice take it to either a dealer you trust or a tranny shop you can trust. if your not comfortable driving it get it towed.
