    Lee its not that I didn't find your advice helpful, I am looking for input of others as well. I hate to put $600 to $700 into it to find that it is not the solution. Does anyone know the frequency of this solenoid failure or whether is is likely to be just one of multiple problems? Is aamco saying rebuild it just because that is easier for them?

    The issue is this. Code 29 76 and 86 on my 95 Seville (133K miles) transmiision. It is now in fail safe mode and operating in 2 nd gear and will not shift. AAmco says rebuild $2400.00 another transmission shop says the computer indicates it is the solenoid and should take $650.00 to replace. Is AAMco just doing the replace rather than repair routine? or is this solenoid replacement not a good idea? Is there likely to be more wrong with this transmission or is this a common failure of the solenoid?

    A mechanic that has checked out the car will definitely be able to tell you better and since that is what he suggested I definitely recommend that repair as it is much cheaper then a rebuild.
    Thanks,

    Rebuild or this repair are you only two options it is up to you what you want to spend. I would recommend the repair first.
    Thanks,

    Yes, easier and much more profitable then actually fixing the real problem. These problems occur enough that they have this system of errors so that it is easier diagnosing. If they didn't have these problems they wouldn't have developed the system to diagnose them. I don't think any input from any of us experts is going to compare to an honest mechanic with the proper transmission equipment. If they are honest I am sure either way you will be happy with the end result.
    Thanks again,
    Lee

    being that its a cadillac there aren't many repairs that are less then 600$, you might want to consider a car that repair costs are not so high on.
    Thanks,

    Like I said get the solenoid repaired then go from there. One code trips another. Sometimes you gotta bite the bullet. I hope you will reconsider and accept and rate my solution accordingly.
    Thanks,
    Lee

Shift solenoid gone bad


saw your comment

may not be the solenoid

did you use a scanner to let you know if it's that?

it's under fail safe mode right now, not allowing you to go past that speed

in my case, the trouble code

FOR MY vehicle was a bad Vehicle speed sensor

and had set the check engine light as well

autozone, advance auto parts, and aamco transmissions can scan the car's computer for free

2006 BMW 750 Li My dynamic drive inactive light came on, then a generator fault light came on


BMW has been using electronically controlled automatic transmissions in most models since the late 80s. These transmission systems employ a transmission control unit which controls electrical solenoids to manipulate the various control and shift valves and functions in the transmission valve body. When the transmission control unit detects a problem that it thinks could be damaging to the transmission or engine, it goes into a fail-safe or limp mode. In this mode, the transmission will function in reverse normally, but in forward it will operate in only one gear (whether you have the shifter in D, or any of the lower gears). This will typically be 3rd or 4th gear, depending on the model. It will start in this gear and stay in this gear with no shifting. You would experience this as sluggish acceleration and higher than normal engine speed at about 40 mph and above.

If you must drive the vehicle when the transmission is in the fail safe mode, accelerate gently and keep the road speed lower than full highway speed.

Earlier models do not employ fault codes and must be diagnosed manually. Late models do employ fault codes and a diagnostic/scan machine can be used to check and read the faults to assist in diagnostics. Note that this is not your common OBDII engine management fault code tool. This is what A BMW dealer or a properly equipped independent shop would have for full vehicle system diagnostics and coding operations.

My 2002 jaguar s-type will start but it will not go anywhere when I press the gas pedal. My husband put fuses in each fuse box and then a light came on that said FAIL SAFE MODE. What can I do?


the message "fail safe mode" is telling you that there is a fault in either the engine or gear box. In your case the problem is in the transmission. Run the fault codes and check for a torque converter servo/solenoid failure or a TCM problem. Check that there is oil in the transmission.

05 mini cooper S went into limp home mode, warrning lights blinking, shut off and re-started. Stopped for a bit then back into limp home ? what might be causing this


Look in the owners manual

There is usually only a couple choices
when you go into Fail Safe

ETC Fail Safe -- for ignition problems,to protect the converter
Overheating Fail Safe
Transmission Limp Mode or Overheat

Just examples
Don't know your vehicle systems

Check for codes as ALWAYS WITH ALL
VEHICLE PROBLEMS first thing you do,
don't need to ask any questions

Check for codes-- then google them

Van did not shift correctly; very slow but finally did shift gears. Advance Auto machine showed code P1715. What does this mean?


It means shift solenoid B inductive signature. Basically, the van is not able to properly control it's shifts due to either an electrical problem leading in to the transmission solenoids or due to an internal transmission issue. This is not something you really want to mess around with. The transmission sounds like it is basically in 'fail-safe' mode meaning that it is trying to protect itself even though there is a problem in the system. I highly recommend you get it to a shop ASAP so that you minimize the damage.

What does an orange diagram of engine light means when it shows off


The amber colored engine lamp means that something is wrong with either the engine or transmission systems. Input sensors monitor the engine and transmission to be sure they are within factory specifications. With this information the computer can adjust things like fuel control, idle speeds, transmission shift points etc. If an input or output is not working correctly the computer will sense this an throw an engine lamp on the inform you that there is a concern. In most cases the computer will use information from other sensors to keep the vehicle running until repairs are made. In more serious cases, the computer will flash the engine lamp and/or put the vehicle in fail safe mode. Fail safe mode will limit the amount of fuel to the fuel injectors and sometimes limit the transmission speeds and throttle response. You need to have codes retrieved either from a dealer, service station or auto parts store. The auto parts store will usually do it for free but their tester may not pull all codes. Good luck.

Fail safe mode came on what can we do


when a car goes into fail safe or limp mode it is caused by an inportaint sensor the car needs to either run the motor or shift the trans..ikt then runs or operates on the driving info that the ecu has stored to be able to get it home or to a shop..youj will need to have a diagnostics ran on it and have the cars computer read to retrieve the code to idenify the problem and once the problem componet is replaced the car will automaticly return to normal operation
