I have a 2001 chrysler concorde. the trouble codes

Question edited for clarity.
Question moved to model category.

This is one where you need a specialist.

The P0733 code means that the powertrain control module (PCM) has detected something unusual with the ratio of the third gear in the vehicle's transmission. This will usually have to happen multiple times before a trouble code will be stored.

P0733 OBD-II Trouble Code: Gear 3 Incorrect Ratio

And Specific to your vehicle as it is a known issue

code p0734 refers to gear 4 --incorrect ratio===causes--wiring---TR sensor/ switch--shift solenoids---transmission mechanical faulty

P0734=A/T 4th gear incorrect ratio. This has nothing to do with the speed sensor. If the speed sensor was faulty, it would also set OTHER gear incorrect ratio codes. My experience tells me the 4th gear incorrect ration indicates the torque converter clutch (TCC) is slipping and nothing more. Unless there was a speed sensor DTC (Diagnostic Trouble Code), the sensor is not the issue (yet). The fact P0734 was set (trust the computer), the TCC is slipping (out of range). Question: Maintenance history may indicate the wrong transmission fluid may have been introduced. Hyundai's Transmission fluid is strictly SPIII... there is no substitute. The incorrect fluid will cause 4th gear slippage. Now, having said that, it doesn't mean the 4th gear (lock-up) clutch isn't worn out. Have a qualified/certified Hyundai Service Technician properly diagnose this issue.

This is what your codes mean:

Trouble Code-P0734 (A/T Additional Gear Ratio Error In Fourth Gear)

Trouble Code Conditions:
Vehicle driven to a speed of 4-37 mph at more than 500 rpm, gear selector in 4th Gear in Drive, and the PCM detected too much difference in the engine speed and output shaft speed.

Possible Causes:

• Customer may complain of intermittent 4th gear operation
  
• O/D and 2/4 pressures less than 75 psi
  
• O/D or 2/4 clutch volume indexes out of specification
  
• O/D accumulator seals are damaged
  
• Transmission enters "limp in" mode running in 4th gear
  

Trouble Code-P0735 (A/T Gear Ratio Error Fourth Prime)

Trouble Code Conditions:
Vehicle driven any forward Gear, and the TCM detected the ratio of the Input speed to the Output Speed did not match the current Gear Ratio (this test can take up to 5 minutes).

Possible Causes:

• Related Gear Ratio trouble codes may be stored (note that some of these Gear Ratio trouble codes may be intermittent)
  
• Transmission has internal problems or damage present
  

You have a transmission problem.

They all point to your Transmission Governor and Gears. You will need to take your vechile to a Transmission Shop to diagnose the problem

P0731 Gear I Incorrect ratio

P0734 Gear 4 Incorrect ratio

dodges do not have a strong transmission, I would be checking salvage yards for a replacement.

all the codes listed above are saying incorrect ratio for each gear,you should take this to a dealer he can determine which faulty sensor on the transmission is causing this,it is not a internal transmission problem

P0732 Gear 2 Incorrect ratio
P1782 P/ES Circuit Out Of Self Test Range
P1787 2-1 Downshift Error
P0700 Transmission Control System (MIL Request) Malfunction

Here is the deal, u have some serious transmission related faults, in order to sort this out u will need to take this to the dealer, allot of testing is required to get to the bottom of this, if I had to guess I would say the trans is going to have to be overhauled.

HI....
I read your problem.
Here is some information about you problem.
2000 Chrysler cocorde. has a 42LE transmission.

The code P0700, Will set for an internal Trans. controler fault detected. "" For any fault detected on a trans. this is the first code to set. After come the other ones.
If it come alone, you will need to make some test to determinate
If the TCM ( Transmission controler module) is fault.

P0731- Will set if ratio of input RPM to output RPM does not
match current gear ratio.
one of the commom problem of this code is a Trans. slipping condition. or other trans. codes related.

If you can go to a Trans. specialist for a proper diagnostic and possibles solutions.

THank you I hope this information work for you.
