TCS (traction control system) You will have to have someone plug a OBD II reader in and retrieve the code.
Please let me know what you found.

Your car has a slot under the steering wheel. Some cars will have a cover over it. It will be easy to find. Just plug in an OBD2 tool into that slot. You can borrow one from the autozone if you don't have one. They are under $100, and I think every car owner should have one. It will tell you what is wrong with your car, taking out a lot of guess work. It will also reset the MIL (engine light).
You may have a problem with your traction system, which is often tied into the ABS, as they share use of the wheel speed sensors.
The problem should be reveiled with the scan tool. It could be an electrical short, damaged wheel hub manets or to speed sensors in wheels, bad control module,...you can check the sensors at each wheel and the teeth in the hub for damage...need to get under the car and possibly take off tires for access. They are on the inside of the rim at the hub. The sensors pull right out. Put a small film of wheel grease on it before you put back in. Use flashlight to look in the hole it came out of to see the magnet wheel.
Good Luck!

TC means traction control you can turn it off after you start your car but it's recommended to keep it on while driving in rain, snow. This automatically goes on when you start the car. The check engine light means you either need a O2 sensor your car, may have three of these or it's your MAF Sensor Mass Air Flow Sensor located on your air intake this will make your engine hesitate or stall if it's this sensor. But if it's your O2 Sensor then you should take it to a mechanic and have them run the codes so they can get the right sensor for your car it is an easy fix but with the engine light on it could cause serious damage and will not pass your emissions with this light on .

The transmission locks into 2nd gear and woln't come out unless I restart the truck, what is wrong


Sounds like it's going into "Limp home mode"
When the computer detects a problem with the tranmission it drop it into a low gear just so you can get the vehicle someplace to service without doing any more damage.
Have the transmission looked by a professional

Transmision starts out in 1st shifts to 2nd then third but will not shift into overdrive , but once it reaches 3rd gear ,it stays there when you come to a stop . after that it will only shift manually...


Sounds like your transmission is in limp mode. This is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

The other from what you described, trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Thank you for using fixya and have your Safari scanned for the DTC codes that would indicate what issues your transmission is having to put you in to limp mode.

2002 Impala: transmission limp mode...


Most transmissions have a limp mode, or limp-home mode.
If the driveline computer thinks there is something wrong, it can lock the transmission into one gear, such as 2nd gear. Usually reverse will also be available. The Impala automatic has 4 speeds. 2nd speed or gear will get you home, but the engine rpms can get a little high. I wouldn't get on the expressway will in limp mode.
Before taking to the shop, you might want to try and reset limp mode by turning the car off for a couple minutes, or you may have to disconnect and reconnect the battery.

check your fluid level in transmission. Also check for antifreeze in transmission , noticable on dipstick by a gray cast or antifreeze color Gr/red. Would also be locted in radiator. have you had the filter changed in trans? 60,000 miles plus would be needed to be changed if not already done . When you shut engine off the filter would drain screen and when you started it back up it would **** debris back and cause valvebody to plug again causing engine service light to come back on

When i slow down the trans shifts hard and stays locked in 1st or 2nd gear untill i restart the car it is a 2003 dodge intrepid 2.7


This is called a 2nd gear limp mode -- it is a safety devise in the computor to prevent interior damage to the transmission -- the cause could be a speed sensor or a blown rear low/reverse seal inside the transmission.

4L 60E - 2001 k1500 will not shift into 3-4. Oil is not burn't and stifts great into1-2


  • No 3rd or 4th gear: “3-4” clutches are worn out. R&R. The car is safe to drive (in 2) until you can get it fixed.
  • Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.
  • No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : Shift A solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.
Check to see if your transmission is in the limp mode, which would only give you 2nd, 3rd and reverse gears. No 1st or 4th gear.

My volvo 850 transmition cut out on me. For a while the arrow on the dash was blinking and it would switch to limp mode. I brought it in to be looked at and they didn't find a problem. Last time it...


Any time the transmission goes into the limp mode, it generates an error code that tells what caused it to go into limp mode. It could be something as simple as a loose connection on a sensor for the transmission computer. The code would explain which sensor was sending the correct signal.
By restarting the car you are resetting the transmission computer, clearing the limp condition.

Transmission problems


I have a 02 dodge intrepid and it was getting stuck in 2nd gear. This is called "limp mode", designed to get you off the road . I had to replace the transmission control solonoid, and at the same time, had the tranny serviced. the tech also found a broken spring in the valve body. total cost was $600.

Transmission locked up, felt like it was stuck in second or third gear. not shifting. shut engine off and restarted , shifting properly now. what causes this.


It was a temporary fault that put the car into limp mode (a safeguard operating condition designed to protect the transmission in case of serious failure). Sometimes a transient fault can occur, and the car goes into limp mode just to be sure it's not for real. Shutting off and restarting the car is the usual way to clear the fault and return the car to normal operation - if the problem was real, the car would've stayed in limp mode after restart, or gone into limp once you started driving again. I wouldn't sweat this one, since it went right back to normal operation.
