    At first before the reverse went out, When i was driving it on a hill with th trailer it would get stuck in the low gear and I would have to pull over and turn the van off and shift the gears in park, reverse,drive and 1 2 gears. Then it would work, but after awhile then the reverse went out.



    Can i fix the reverse and please advise me on what i need to do

    It wont go past 40mph once it reaches the 40mph it just stays in the low gear and rives real high.



    It shifts drive,park,netural,and 123 but no Reverse and when it drives it gets stuck on the 40mph and i cant go any faster it will just rive real high.



    please advise

    I have some questions about the sun gear shell, I know that is a common problem on the 4L60E but my transmission is a 4L80E

    If i get the sun gear shell is that going to make my transmissions reverse come back and start working?

    What about the problem with it getting stuck in the low gear?

    Can you give me the name of that after market company and their contact info.

    I forgot to mention that i have a 2000 Chevy Express 3500 6.5 Liter Turbo Diesel.

    Are my two problems fixable? the gears getting stuck in low
    and having NO REVERSE

    OR will i need a new transmission?

    Please Advise

Is it missing reverse 2nd and 4th? If so it has a broken reverse reaction shell. They aren't too hard to replace

    Now that reverse doesn't work, does it stick in 1st? Or does 1 thru 4 work fine?

  • Clint Smock
    Clint Smock Mar 02, 2009

    Yes, It sounds like you broke the sun gear shell. There is an aftermarket company that has redesigned these to keep them from breaking. The first thing you need to do is remove the transmission. If you think you can handle fixing it, I will walk you through it. Otherwise you need to take it to a transmission shop. Once you describe what is doing they will know exactly what is wrong and tell you exactly what I just told you. You haft to disassemble the transmission to fix it but you won't need any special tools to complete the job.

    I'm sorry I assumed you had a 4L60E. Forget what I said, lets start over. First you need to drive the van in Manual first up to 20 mph and let off, see if the transmission will pull the engine down. Let me know

  • Clint Smock
    Clint Smock Mar 03, 2009

    I just went back through your log, since you have a 4L80 it sounds like you have burnt the Direct or (High/Rev) clutch. But try what I said about the engine braking.

Nissan maxima code po780 2005


code p 0780 refers to gear selection--shift malfunction===causes --wiring --TR( transmission range) sensor--shift solenoids ---transmission mechanical fault
take it to an accredited auto transmission specialist shop for an exact diagnosis of the fault
I seriously doubt that you have a transmission box mechanical fault so get a second opinion if a replacement transmission is suggested

Sep 09, 2016 | Nissan Maxima Cars & Trucks

Tip

My car does not shift in second gear.


Hi.

The first thing to do is replacing the transmission fluid. Metal debris inside the transmission box gets mixed with fluid and can cause similar problems.

The automatic transmission uses throttle position sensor to determine position and opening of throttle.
IF throttle position sensor is defective, the car may have problems shifting into one or more gears.

The automatic transmission is controlled by an electronic control module, that is energizing a set of solenoids to shift into gears.
The control module is a rectangular box, often located behind the dash and wired to transmission. The solenoids are attached to valve body,inside transmission.

If a solenoid is defective, or if control module is defective, the car may have problems shifting into one or more gears.

Problems concerning transmission control module, TPS and transmission solenoid are usually detectable reading fault codes stored on the car main control module (ECU/ECM).

Transmission problems are often returning a code p0700 after an OBDII scan.

Stored codes can be retrieved using an OBD scan reader.
If the car auto transmission is not shifting into gear, talk to the mechanic about the problem.
Only when the car has a really high mileage, or when there is a factory problem there is need to replace the gearbox.
A damaged gear box at low mileage is rather unusual.

Interrogate ecu using atologic P0732 Gear 2 incorrect ratio P07667 shift Sol d


Gear 2 Incorrect Ratio Our emissions expert has put together the following information about the P0732 fault code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
OBD II Fault Code
  • OBD II P0732
Fault Code Definition
  • Gear 2 Incorrect Ratio
What does this mean?
The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels.
Code P0732 When the code P0732 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is seeing a greater than a specified RPM difference between the rotational speed of the Input RPM Sensor and the Transmission Output RPM Sensor when the vehicle is in 2nd gear. This can occur during shifting or when driving at steady speeds. It often implies that the transmission is slipping.
Symptoms
  • Check Engine Light will illuminate
  • Vehicle will not shift properly
  • Decrease in fuel economy
  • In unusual cases, there are no adverse conditions noticed by the driver
  • In some cases, there may be performance problems, such as dying when coming to a stop after driving on the freeway and/or misfire-like symptoms
Common Problems That Trigger the P0732 Code
  • Defective 2nd gear shift solenoid
  • Defective 2nd gear related gear set or clutch pack
  • Defective Engine Coolant Temperature Sensor
  • Defective Valve Body
  • Dirty transmission fluid that restricts the hydraulic passages
Common Misdiagnoses
  • Engine Misfire problem
  • Internal Transmission problem
  • Driveline problem
Polluting Gases Expelled
  • HCs (Hydrocarbons): Unburned droplets of raw fuel that smell, affect breathing, and contribute to smog
  • CO (Carbon Monoxide): Partially burned fuel that is an odorless and deadly poisonous gas
  • NOX (Oxides of Nitrogen): One of the two ingredients that, when exposed to sunlight, cause smog
P0732 Diagnostic Theory for Shops and Technicians
When diagnosing a P0732 code, it is important to record the freeze frame information and then to duplicate the code setting conditions with a test drive. Pay close attention to the engine load, throttle position, RPM, and road speed because a P0732 can be difficult to detect.
One should monitor the RPM input speed and compare that to output speed RPM on a smooth, flat surface after the vehicle is warmed up and the fuel system is in a closed loop. Monitor how the 2nd gear solenoid configuration responds to an increased amount of throttle. The 2nd gear related solenoid should stay in 2nd gear and the transmission should NOT slip.

PO766

Possible causes- Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid D valve
- Shift solenoid D valve harness or connectors
- Shift solenoid D valve circuit is open or shorted
Tech notesWhen the a transmission solenoid is stuck off, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced. When is the code detected?The P0766 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off P0766 Description Shift solenoid valve D is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position.

How do i fix a po757


Hi there:

DTC P0757 MAZDA - Shift Solenoid B Stuck On

The P0757 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck on.

Shift solenoid valve B is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position. When the a transmission solenoid is stuck on, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced.


Possible causes:

- Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid B valve
- Shift solenoid B valve harness or connectors
- Shift solenoid B valve circuit is open or shorted

Sounds like you may have a shift solenoid sticking.First thing i would do is change the fluid and filter in the transmission.Graphite build up causes problems like this.

I have no gears forward or reverse. My Vehicle is a 2003 Dodge Ram 1500 4x4 Hemi with 170,000 on the clock. Fluid is clean and full with no leaks. I have the following trouble codes:...


Your scanner will give you the code but it will not tell you how to fix your vehicle. Scanners basically tell you what systems to check or what systems are failing.

These are what your codes mean:

P0700: Transmission Control Module
- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module. This is just a informative code.

P0734: Gear ratio error in 4th gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0732: Gear ratio error in 2nd gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0731: Gear ratio error in 1st gear
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

P0871: Transmission Fluid Pressure Sensor Switch C

P0876: Transmission Fluid Pressure Sensor Switch D

Emissions Codes:

P0400: Exhaust Gas Recirculation Flow Malfunction
- Harness or connectors (EGR volume control valve circuit is open or shorted.)
- EGR volume control valve stuck closed
- EGR volume control solenoid valve
- Dead (Weak) battery
- EGR temperature sensor and circuit
- EGR Valve

How to fix :
- Clean EGR Valve
- Repair EGR harness or connector
- Replaced EGR volume control solenoid valve
- Replaced EGR volume control valve

P0440: EVAP Emission Control System Malfunction
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

P0456: EVAP Control System Leak Detected (Very Small Leak)
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

P0441: EVAP Emission Control System Incorrect Purge
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

How to fix:
- Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

Based on the info check your EVAP system. I would check for leaks and maybe replace the EGR and the canister.

For the transmission check the TCM also you may need to take it to a mechanic though.

Hope this helps a little.
