Question about Cars & Trucks

1 Answer

I have a 2003 Deville and I recently had my transmission rebuilt. Now I get the p0733 and p0734 codes. I know what they mean. If I reset the code it is fine again and it does not happen always. So obviously the fluid is new. What could be the issue.

There is a problem with the TCM ( transmission control module ) you need to take the car to the dealership and get it reprogrammed.
The TCM controls the gear ratios of the transmission.

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 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

SOURCE: 2001 Jeep Grand Cherokee won't shift out of first

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.

On a 2001 Chrysler 300 what does p0 734 and mean and how do you fix them


Code P0734 more or less means transmission is slipping in 4th.
  • Defective 4th gear related shift solenoid
  • Defective 4th gear related gear set or clutch pack
  • Defective Engine Coolant Temperature Sensor
  • Defective Valve Body
  • Dirty transmission fluid that restricts the hydraulic passages

Loss of power, transmission issues


code p0700 refers to transmission control system/MIL --malfunction===causes --wiring ---TCM (1)
code po740 refers to torque converter clutch (TCC) solenoid--circuit malfunction===causes--wiring--TCC solenoid--ECM/TCM (transmission control module) (again)
code p0871 refers to transmission fluid pressure (TFP) sensor C -range/ performance problem==causes---wiring--poor connection--TFP sensor--ECM /TCM (yet again)
code p0734 refers to gear 3 ratio (po374 is gear ratio 4) incorrect ratio===causes --wiring--TR sensor/switch--shift solenoids--transmission mechanical fault (causes are the same for po733&734)
code po846 refers to transmission fluid pressure (TFP) sensor B-range/ performance problem===causes ---wiring--poor connection--TFP sensor--ECM/TCM (again). Give the clutch a miss as you still have 1st gear and if the clutch is not working you will not be going any where. Have a pressure test done on the transmission to check for internal mechanical failures (pump ). The rest are sensors are wiring connections , sensor and TCM. My bet is the TCM unit. Have it checked out. What ever you do treat any suggestion of a new transmission with a grain of salt until you are shown proof positive that you need one.

Suzuki 2005 verona codes coming up are P0700, P0741, P0733 and Po734 what do these mean


bad A/T
automatic transmissions are complex, and expensive to repair /replace.
take it to an ASE pro.
The suzuki has factory codes too, so you need them for full diagnosis.
that takes a special too, not just your generic P0 codes.
this tells me , the tranny is slipping
tcc not locking up and 3nd and 4 gear , not right ratio.
slips. and that is serious. get a full diagnosis.
5sp M/T/s rule, A/T not.

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.

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
