SOURCE: high rpm shift

I'd have to agree with Smithbrother and go for the valve body control.........sometimes soenthing simple goes unchecked...make sure your tach is okay.

SOURCE: tranmission shift problem

Check the gearbox filter, it may require replacing.
Its inside the gearbox below , remove the (gearbox)sump and you will notice it.

SOURCE: my 88 chevy with 700r4 wont upshift from 3rd to 4th

you have a valve body problem, some of the speed sonsor controls are malfunctioning... need to get into the valve body... check fluid condition for dirty and burned condition...

What does a shaft speed sencer do for a 2000 cirrus


According to Stratusphere.net, "Symptom: The car won't shift out of 1st gear. The 'Check Engine' light is on.

The speedometer doesn't work for this one. You're only able to go about 30 MPH without going above 4000 RPM.

Likely Cause #1: The Output Shaft Speed Sensor went bad.
Likely Solution #1: Replace the sensor (Part #4800879)."

The good news is that they are relatively cheap if you can install them yourself.

2005 chrysler sebring loses power driving up hill & RPM is up high, Ive changed, spark plugs & air filter. dont know what to do.


Not sure I am following your story.
Are you saying the transmission is slipping and therefore the RPM is high even tho the road speed is not ?
Or is the transmission not upshifting to the next gear at a normal road speed ?
Is the check engine light on ?

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.

2003 dodge neon only runs in first gear slips at 1500 rpm , must shut car off an turn on for it to run , wont shift out of first.runs fine in reverse.is it a pcm problem.


No,Your car is in "limp"mode,
there are three sensors on the transmission that tell the computer how fast your going so it knows to upshift,
have someone check input sensor,output sensor,and speed sensor.
