The 1st thing u need to do is have the transmission electronic control system tested for fault codes, this is the starting point for any successful repair of a electronically controlled transmission which u have in your car. I base my suggestions on 35 years of real world experience and factory training in diagnosis and repair of automotive electronic control systems.

    Testing for system fault codes doesn't have anything to do with parts be changed, it is a test, the codes represent the faults the computer sees in the system during normal operation, the advice is the same, get a fault code test run on the transmission control module. so get the fault code test run, Aaco transmission will do this for free as well as road test the car and give u their recommendations to repair it.

My car is stuck in limp in mode I have replaced speed sensor and I'm getting p 0700 it's a 02 stratus I was told if I have the codes reset that the car should shift correctly


Incorrect information the code is because of a system malfunction and that is what is causing the shift problem. Resetting the code does nothing. Your code is transmission control circuit malfunction.

1995 cirrus transmission limp mode


THE INPUT & OUTPUT SPEED SENSORS ARE ON THE TRANSAXLE , THEY HAVE A TWO PRONG WIRE CONNECTOR @ EACH SENSOR. THEY ARE IMPORTANT !!!! THEY SEND INFO TO THE CONTROL SOLONOID FOR SHIFT QUALITY AND SHOULD ELIMINATE THAT LIMP MODE CONDITION. I WOULD ALSO CHANGE THE TRANS FILTER & FLUID, USE ATF+4 FLUID ONLY , DONOT USE DEXRON FLUID, ITS NOT GOOD FOR THIS TRANSAXLE, USE ONLY ATF+4 , ONLY !!! CLEAN PAN & THE SMALL MAGNET IN BOTTOM OF PAN . USE A NEW GASKET & FILTER. THE LOCATION OF YOUR SENSORS ON THE TRANSAXLE , STANDING IN FRONT OF CAR, HOOD OPEN, LOOK DOWN @ TRANSAXLE, (TRANSMISSION), USE FLASHLIGHT TO LOOK FOR SENSORS, INPUT , MIDWAY, CLOSE TO CONTROL SOLONOID, OUTPUT, TOWARDS WHEEL. LOWER AREA/TRANS, ARE YOUR NEUTRAL SAFETY & BACKUP SWITCHES ! THREE PRONG CONNECTORS, HOPE THIS HELPS !

95 stealth...what else can it be? I bought this car 3 months ago and haven't gotten to drive it yet. It is stuck in limp mode.


Can you pull any errors off the ECU? Do you have the standard dash installed? My Alfa will not change up from second if my dash is not installed.

I have a 2001 Chrysler T&C. The transmission is stuck in limp mode. I have replaced the TCM and it is still in limp mode. I see manys postings with this problem but nobody posts what they did to repair...


Many times on Chrysler products, one or both of the speed sensors screwed into the front of the transmission will fail, and cause the tcm to go to limp mode. Also make sure you have power to the tcm. Someone with a scanner can check these for you, or the speed sensors are less than 20 bucks each, replace them both and cross your fingers. If the transmission has internal problems, the tcm will sense this and go into limp-mode as well.

My 91 dodge stealth is in limp mode how do i fix this transmission problem


Your car is in "limp"mode because the computer doesn't know what speed your doing,So it doesn't shift,
There are three possible reasons for this,
#1= input sensor faulty on transmission,
#2=output sensor faulty on transmission,
#3=speed sensor faulty on transmission,
you need to have the transmission codes read to know which one,Autozone checks codes for free.

I just rebuilt my 4l60e and reinstalled and now i have reverse, manual 1, manual 2 and nothing more. there was a check ball stuck in the separator plate i just assumed it was stuck from trash or...


Note that many problems that show up as transmission issues are actually PCM or electrical, and may be external to the transmission. Try a different PCM, and check for chafing where the cables come out of the PCM.

The transmission is on the same fuse as the MAF, O2 sensors and at least one other sensor - if an O2 shorts out, it will blow the fuse and the trans will go into limp-home mode. Be sure the trans has power and the fuse is not blown before doing anything else.

Limp mode 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.

Check the wire harness clip on the transmission, passenger side by the catalytic converter. Look for any damages due to corrosion or brake in the wire leads. it's common for the clip to brake and the wire harness to loosen causing the transmission in to limp mode. Good luck and keep me posted, be glad to help you get your transmission running again soon and please rate.

Check for check ball wear on the separator plate and address it if needed. The 1-2 check ball wears out and sometimes the check ball blows through or sticks in the plate causing troubles.

Just thought I would point out a few items to think about. Good luck.
