    Thank you for your prompt response. The car has 275,000 km I will check the input and output speed sensors and the wiring connected to them and report back. If this helps with the diagnoses of the damage, The car was being driven at 35 miles per hour put into neutral and then back into drive at about 3000 rpm

There are some sensors on the transmission that tend to go bad. You may also need to check the wiring. Could be a computer problem. How many miles?

I have a 1998 dodge Grand Caravan with codes P0700,P0734 & P0733. What does this mean?


P0700 is a informative transmission code, about some problem there; the P0733 and P0734 is the specific problem there.
I would first try changing the fluid and filter. Although the fluid may look like it is brand new, with 100K on the fluid, I can assure you that even if those miles were all highway at steady speed and no load that the fluid has deteriorated and no longer lubricating the internal parts properly and that there is some debris in the ******.If codes return and shifting problems are still present, there is definite internal failure, possibly the pump or in the clutches.
DTC P0733The powertrain control module (PCM) uses the crankshaft position (CKP) sensor, input speed sensor (ISS) and output speed sensor (OSS) to determine engine speed, input shaft speed and output shaft speed. These sensor readings are used to determine the current gear ratio and RPM slip across the torque converter. The PCM uses this information from the sensors to determine if the commanded gear matches the actual gear. During normal driving conditions, the PCM will adapt main line pressure via the pressure control (PC) solenoid to prevent slipping and harsh shifts. Shift solenoid 3 is used to apply or release third gear clutch. The PCM controls 3rd gear by controlling the ground for shift solenoid 3. The PCM will turn the solenoid OFF, open the driver circuit, when 3rd gear is commanded On to apply 3rd clutch. Shift solenoid 3 is supplied ignition voltage from the fuel pump relay whenever the PCM commands the fuel pump relay ON. DTC P0733 sets when 3rd clutch still slips after the PCM has commanded high main line pressure.DTC Parameters
DTC P0733 will set if the PCM detects an incorrect actual 3rd gear ratio when 3rd gear is commanded On when:- The condition exists for longer than 3 seconds (2001)*- The condition exists for longer than 3 seconds, 1 minute is allowed to elapse, then condition exists again for longer than 3 seconds (2000)- The high main line pressure has been commanded- The transaxle is in a forward gear- The input speed is greater than 224 RPM- The vehicle speed is greater than 5 km/h (3 mph)- The speed noise parameter = NO- The steady state ratio fail counter equals 255 for an in-gear failure, or the shift fail counter is greater than 100 on a downshift or upshift to 3rd gear (128=0 or normal operation)DTC P0733 diagnostic runs continuously once the above conditions have been met.
DTC P0733 is a type A DTC for 2000, type B for 2001.**Applicable to vehicles built after June 2000.
Diagnostic AidsImportant: If DTCs P0745, P0746, P0756, P0758, P0761, P0763, P0766, P0768 or P0789 is set, diagnose that DTC first. A diagnosed PC solenoid, shift solenoid 2, 3 or 4 low/high circuit fault DTC may have caused DTC P0733 to set.Important: If a shift solenoid performance DTC P0783, 4th gear stuck ON, is set, diagnose that DTC first. A 4th gear stuck ON may cause no 3rd gear, no 2nd gear, or TCC stuck Off.
Refer to Pressure Ports - Air Check and Parts Description for pressure apply points and for component/location description.
Possible causes of no 3rd gear are listed in the flowchart on the succeeding page.
Verify TRANSMISSION ISS and TRANSMISSION OSS read correctly on Scan tool.
Make sure the pressure control, shift 2, shift 3 and shift 4 solenoids are not intermittently sticking. A sticking shift solenoid 4 may cause 4th gear to be applied from an initial start resulting in no 3rd gear. Audible sound should be similar for all solenoids. A muffled tone indicates the need for replacement.

P0734 refer at ratio 4 gear, and the rocedure is the same.
Hope helps.

Volvo S80 Faul code 000C


Hi there:
Diagnostic trouble code (DTC) TCM-000C is stored if the control module detects that the vehicle speed and engine speed (RPM) signals do not correspond with the programmed values and that an "incorrect" gear is being used in relation to the calculated gear. This is because solenoid S2 is stuck in open or closed position.

Diagnostic Codes: 000C, 002A, 002B, P0733, P0734, P0756
Tests/Procedures:
1. Clear codes from the Transmission Control Module (TCM).
2. With fluid hot, check transmission fluid for quality and level.
3. Test drive the vehicle. Accelerate from 20-60 MPH when in geartronic mode, gear 4. While doing this, watch input and output speed sensors with a scan tool.
4. If the code returns, the transmission is slipping, and the input and output speed sensors are updating, the problem is internal to the transmission.
5. If transmission is replaced, test ATF for coolant contamination per TNN 43-48. Replace radiator if necessary.

Potential Causes: Transmission Mechanical Problem

Tech Tips:
TCM-002B 4th gear. Incorrect gear ratio. This code sets when the actual gear ratio deviates by more than 10% of what is programmed into the TCM.
TCM-002A 3rd gear. Incorrect gear ratio P0756 - TCM-000C - Shift solenoid S2, hydraulic malfunction If the transmission is replaced, be sure the mating surfaces between the engine and transmission are bare metal and clean. If not, the engine may not start after assembly.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Code po734, po735


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.

2001 Jeep Grand Cherokee won't shift out of first gear and the fault codes are P0733 and P0734.


P0733=Gear 3 Incorrect Ratio
P0734=Gear 4 Incorrect Ratio,
your transmission is in "limp" mode,
Have the following sensors checked on the transmission,input sensor,output sensor,and speed sensor.
The transmission is not getting a signal from one of them,So it doesn't know how fast your going so it doesn't up shift.

Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.

98 voyager is in limp mode, codes p0733 and p0734 are third and fourth gear ratio error. had one person say the input and output speed sensor on tranny are bad. another said the pin that holds the band on...


It's neither. That trans does not have a band. If you had only one gear ratio error it could possibly be speed sensor but not 2. Sounds like either shaft broke inside or sun gear.

P0733 IS GEAR RATIO ERROR IN 3RD AND P0734 IS GEAR RATIO ERROR IN 4TH..THESE CODES USUALLY MEAN AN INTERNAL PROBLEM IN TRANSMISSION,BUT CHECK WIRES AT SPEED SENSOR CONNECTORS FOR BROKEN WIRES BY PULLING ON WIRES AND WIRING NEAR SOLENOID PACK FOR CHAFING..I HOPE THIS HELPS..YOU MIGHT WANT TO DROP THE TRANS PAN AND LOOK FOR A PLUGGED FILTER OR DEBRIS IN PAN..MAKE SURE THE TRANS COOLER IN RAD HAS NOT FAILED ALSO

I WOULD TRY REPLACING THE INPUT SPEED SENSOR..A DEFECTIVE SPEED SENSOR CAN CAUSE ALL OF THESE FAULTS..IT IS LOCATED IN FRONT OF TRANS ABOVE SOLENOID PACK..IT IS THE ONE CLOSEST TO THE ENGINE..IT SCREWS INTO TO TRANSMISSION..A 1 INCH SOCKET FITS IT..ALSO CHECK WIRING TO BOTH SPEED SENSORS..A SENSOR IS ABOUT 35 BUCKS,AVAILABLE AT YOUR LOCAL DODGE DEALER..GET A NEW ONE AND YOU'LL SEE WHAT IT LOOKS LIKE..FAIRLY COMMON PROBLEM..HAVE REPLACED LOTS OF THEM
