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.

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.

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.

I had to replace my transmission in a 2001 kia rio and now i have codes coming up P0705 P0733 P0734 P1500 P0740 I know before i replaced my transmission the o/d light was flashing on and off but i...


all of the above codes refer to the transmission. have you tried to erase codes using an OBD-II scanner. if no scanner go to auto-zone and tell them you need the codes erased. they will do this for free. evidently the pcm thinks there is still a problem with transmission. clear the codes and see if they come back. have a good day !

2001 buick lesabre is running slightly hot. i just replaced the thermostat and 2 elbow joints (sorry dont know what their called) and did a complete flush about a month ago


replacing the thermostat is exactly what i would have suggested for your vehicle for the overheating issue. try this,with the engine running at operating temperature,check to insure that the cooling fans coming on when the engines gaining temperature. your cooling fan may be going bad and not coming on when needed,in this case it may be a bad cooling fan sensor,or just a bad cooling fan altogether.with the engine running after you've driven the car until it gets warm,open the hood and look visually at the cooling fan to insure it's running{the engine fan} in front of your radiator. if it's not running {fan} check in the main fuse box under the hood for a bad engine fan relay 1st if no bad relay,then check for a bad engine fan motor.with the key switch in "off"position try to spin the engine fan manually by hand. if it does spin by hand it still may be a bad fan motor. or bad fan sensor.do you have a check engine light on? if so you can have it code read at any auto zone or advance auto for free.this may be of great assistance to you if the check engine light is on. hope this helps and thank you for choosing fixya.com

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

Cooling Fan Fuse


Sounds like a short in the wiring, or a bad fan motor drawing too much current. Check the wiring for shorts, if none are found, replace the fan motor.
