2nd and 5th gear ratio errors after replacing solenoid pack

Just had solenoid pack replaced on 2003 Mountaineer and all the symptoms are the same. It is taching very high on initial take off and the O/D OFF light keeps flashing with "Check Transmission" coming up on the display. Put the computer back on it and it is saying 2nd and 5th gear ratio error

I am a 24 year ford master tech, and over the years we found the harness in the transmission was the cause and not the solonoid as you described, In rare cases the valve body was clogged back forcing the flow, My first bet is the harness INSIDE the transmission

Replace what solenoid specifically? What was the trouble code? Most parts stores will pull OBD-2 codes for you for free and give you a brief description of what they mean. I would try that then come back here.

SOURCE: Mercury Mountaineer transmission is allowing 1st 3

This problem is likely caused by a failed clutch pack or low fluid pressure due to a internal leak. The bottom line here is that you will need transmission pressure gauges hooked up and then road test performed. Also you will need to test the system for fault codes. I think based on the symptoms you will need to replace or rebuild the transmission.

What is the code p1715 on my 2007 mustang V6 4.0 automatic

Diagnostic trouble code (DTC) P1715 will set when a mechanical failure of the SSB shift solenoid is detected. When the SSB solenoid is stuck off, the symptoms will be incorrect 3rd gear ratio or no 3rd gear. When the SSB solenoid is stuck on, the symptoms will be 1st gear ratio incorrect or no 1st gear. The diagnosis procedure directs to check for other DTCs; if there are no additional DTCs for the transmission fluid temperature (TFT) or other shift solenoids, then to replace with a new solenoid and/or valve body.

2002 Ford Ranger throws Trans code p0735 -- 5th gear incorrect ratio. My understanding is basically it's running without 5th gear/overdrive. (It also causes it to shift hard into/out of 2nd, as, from...

to start with there is nothing wrong with the ransmission
It is all electronic faults
the transmission is constant mesh so ratios are not manually changed by done by servos and solenoids
the fault code refers to the TR sensor that can be changed out , the hard shifting is probably dirty oil and the changing between ratios a problem TCM or wiring harness connections
if the transmission oil has not been changed in the last 60K miles , that would be a good place to start, then have the auto transmission professional service center where you are having the oil change done, check out the servo/ solenoids operations

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.

2nd and 5th gear ratio errors after replacing solenoid pack

Try this article. It explains some of the internals of your transmission. HOPE THIS HELPS? FORD "FOUR VERSIONS OF 5R55"
FORD "FOUR VERSIONS OF 5R55" Just as the title states, the Ford 5R55 Transmission has four versions. Ford 5R55 can have an N, S, or W behind those numbers.
  • The 5R55 is a rear wheel drive 5-speed that appeared in 1999 and later vehicles.
  • The 5R55W came out in the 2002 and later Ford Explorer and Ford Ranger models.
  • The 5R55N appeared in the Jaguar S-Type and Lincoln LS and in 2002 in the Ford Thunderbird.
  • The 5R55S without the Select Shift is used in the 2005 and later models of the ford Mustang.In 2003 the Thunderbird and Lincolns switched to the 5R55S that had the Select Shift (allows drivers to shift like a standard without the clutch).
Although the 5R55N is very similar to the W or S models, only a few parts are interchangeable.
We receive numerous calls about these where someone has rebuilt the transmission, yet still experiences the same symptoms. The most common problem we see on these units is the excess wear on the case or valve body.
Transmission case premature wear occurs on the overdrive and intermediate servo bores. Apply oil comes up through the servo pin bore and through the hollow pin applying the servo. This requires the pin to seal in the servo pin bore, as well as the release oil that both servos require. Over time, the number of apply and release wears out and the pin can no longer seal properly. The overdrive servo bore will usually have more wear due to it being used for second and fifth gear. As the servo leaks, which will result in a pressure loss, it lacks the pressure to hold the band completely applied or release it fast enough to prevent the band from being burned up.
These issues can be repaired without replacing the case. Drilling the servo bores and installing a "cesleeve" to compensate for the wear eliminates the need to replace the case. The brass sleeve has proven to be more durable then the aluminum case, giving you more stability. You don't want to use a "used case" as the possibility of the bores being worn in is very likely.
The valve body can also have excessive wear, most often seen on the TCC (torque converter clutch) modulator bore, or main regulator bore. In this case, the high duty cycle of use wears down the bore reducing clutch and servo pressures. Although the PCM (power control module) will try to compensate with an adaptive strategy, the excess wear will cause gear ratio or slipping codes.A valve body repair or update kit will usually correct these problems.
Gear ratio error codes are very common on these transmissions due to servo pin bore wear occurring at a very low mileage, in some cases.You can have a gear ratio error code without having an electrical code (solenoid), but it is unlikely that you will have an electrical circuit code without a gear ratio error code.
These are just a couple of most common problems seen on these transmissions, but not all these problems may have this problem. If you have any version of the Ford 5R55 transmission and are having problems with it, don't hesitate to bring your vehicle into The Transmission Shop to get it checked out. Having a proper diagnostic by qualified techs will eliminate the guess work and save you major expenses in the repair, rebuilding, or replacement of these transmissions.

Please,can you help me fix cods problems p0732,p0734 on my 2006 Mazda Tribute

P0732 - Improper Ratio for Second Gear.
P0734 - Improper Ratio for Fourth Gear.

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as follows:

Torque converter slip ratio = A x C/B A: Output shaft revolution signal from revolution sensor B: Engine speed signal from ECM C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (2nd and 4th) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

This malfunction will be caused when shift solenoid valve B is stuck open.

Gear positions supposed by TCM are as follows. In case of gear position with no malfunctions: 1 , 2, 3 and 4 positions In case of gear position with shift solenoid valve B stuck open: 4* , 3, 3 and 4 positions to each gear position above.

Symptoms: Engine Light ON (or Service Engine Soon Warning Light)

Diagnostic trouble code A/T 2ND GR FNCTN with CONSULT-II or P0732 without CONSULT-II is detected when A/T cannot be shifted to the 2nd gear position even if electrical circuit is good.

Possible Causes:
- Shift solenoid valve B
- Each clutch
- Hydraulic control circuit

Hard shifting from first gear to second after complete stop

It is in the bottom pan. In order to replace it you have to replace all the solenoids. They are all built into a solenoid pack. What does it do when it shifts to 2nd? Not at all or slips?
