97 mit galant in limp mode and displays a flashing

The overdrive light is flashing because there is a diagnostic code stored in the Transmission control mudule.You will need to have the codes pulled to know where the problem is.The 2nd gear only condition is not a symptom, it is limp mode caused by the code being stored.There are about 30 different problems that can cause limp mode,so there is no way to guess.There is a procedure to pull codes that I can give you if you want to do it yourself.Just let me know,Thanks!

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.

There is no point in trying to make heads or tails as to why a lite goes on , there are too many variables to consider.Have the vehicle scanned for codes at Autozone( usually free) and then do the repair accordingly.

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: Transmision is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the underhood 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.

What is "limp-home 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.

Thank you for using fixya and good luck

Car goes into gear but feels very sluggish like the brakes are dragging, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

yes but it will cost a lot more than changing and it usually is not a sucess.

Hi,
is your car a GDI engine? If it is GDI you can't really hear the pump working when you put ign on.
Give me some details and I might be able to guide you there.
Chassis, engine numbers, GDI ??

Can give you some advice on GDI but need to know what issues you are experiencing.
Cheers. [email protected]

Hello, your transmission is in limp home mode. There is going to be a problem with the transmission that the computer has picked up on.
You will need to have a shop check codes for you. Please rate this answer.

it is eletical eather a fuse is blown or the speed sensor didnt get hooked up dose spedo work
