1 Answer

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 in the tranny came out? any idea's?

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.

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.
Check this pinout HERE
P0734 refer at ratio 4 gear, and the rocedure is the same.
Hope helps.

Only code p0734 2001 caravan


Hi there:
This code means that the transmission is slipping in high gear and the TCM (TRansmission Control Mocule) logic thinks it has incorrect ratio since it monitors input and output speed. Keep in mind that TCM uses input from the input speed sensor and output speed sensor to determine gear ratios. The TCM then compares the known gear ratio to the calculated gear ratio for the current range.


Check HERE test procedure.


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.

My 2000 Sephia will only shift gears manually from 1,2, then to drive. I get a code PO734. How do I fix and or slove this problem?


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.Hope this helps, James Booth

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.

Chrysler Neon auto gearbox problems


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

Code p0733, p0717


P0733 Trany Ratio in gear 3. This is a trany fault code and the first thing you should check is your tps sensor using your DVOM meter. Measuring the voltages between idle and WOT (wide open throttle), there should be no interruption in the reading (or glitches). Otherwise, it can play havoc to your shifting cycles which can cause this code P0733. If there are glitches, replace the tps sensor right away and reset the code. If trany is suspected, most common fix for this points to a defective valve body. To verify, it can be done by using a scanner which has the capacity to command the trany solenoids so it can be tested at various trany operating pressures. P0717 is a improper signal from your pules generator A. Which is a the turbine speed sensor on the transmission, You have two of them, the A reads the speed of the input shaft of the transmission and the B sensor reads the output shaft of the transmission. I know with the P0717 it will put the transmission in the limp mode and will not shift past 3rd gear and if your running the transmission hard on third you may have triggered the P0733 which is the 3rd gear slipping. Check the transmission fluid and make sure you have not burnt the fluid, if the transmission fluid is burnt you may want to have a transmission repair shop replace the turbine speed sensor (Pules Generator A) and the fluid and filter. Cross the fingers and hope the transmission was not ran to hard in third causing damage to the third gear clutch packs. Good luck and keep me posted, be glad to help.

98 Intrepid Gone into "Limp Mode"


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?
