SOURCE: limp mode?

It may have a "loss of prime" code that usually follows a service of the fluid and filter. After you're sure the fluid is full at operating temperature, disconnect the battery for a few minutes and reconnect to see if the code resets. I hope this helps.

SOURCE: 01 duramax allison changed fluid and filters now in limp mode

Make sure you have the proper amount of tranny fluild in it and get that Valvoline fluid out of it. Allison transmissons have there own type of tranny fluid and you want to use it. You can buy the right stuff from a Allison dealer. Most Detroit Diesel dealers are also Allison dealers. Look them up in your phone book and they will tell you the quanity and sell you five gallon pails of the fluid. Just get the serial number off of the side of the transmisson before you call. Change the fliters again too. Believe me, this is important. My company has Yard horses with Allison transmissions and you don't want to screw with the small stuff. Service them right and they work as hard as you want.

SOURCE: limp in mode

check for switch batt volts on a scaner could be sol pack or tcm. also look at input and output speed sensors

44re 1999 durango won't start from start easily. High RPM and SLOW start (like not in 1st)


the second code is govener pressure sensor. the pressure is to low. the first code is sensor voltage to low, i would check the wiring where it plugs into trans for corrosion. also make sure the kick down cable on the throttle is connected and not broke because this cable controls the line pressure.

1996 Ford Ranger 4X4 4.0L V6 Manual Trans. Replaced Catalytic and rear O2 Sensor. Throws a Code P1131. Sprayed Carb Cleaner along as much of Air intake as I could, no change in idle. Where should I be...


The first thing i would do is check the fuel pressure it should be 35-45 psi with key on engine off,because low fuel pressure will cause this code too.Also check fuel pressure regulator pull vacuum hose off and if there is any fuel in hose replace regulator.

I have a code p1762 for my 97 jeep grand cherokee


Trouble code P1762 means: Governor pressure sensor offset improper voltage. Gov. Pressure Sensor.It is located in the valve body of the transmission and requires dropping the transmission pan to replace. Sounds much more difficult than it is. Since you have to change your fluid it's a good idea to change the trans. filter .

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.

1996 gmc jimmy will not shift to 3rd gear


Hi, It may be in LIMP 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.

Common failures on 4L60E, symptom any possible repair:

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 :ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

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.

Trans seems noisy when moving in 1st and Reverse, noise goes away instantly if you shift to N or the trans goes into 3rd gear: Reaction planetary is worn out due to high miles or insufficient lubrication. Not a critical failure, but not a good sign either. R&R sooner rather than later.

3rd gear starts, can manually shift through all gears. When car has been turned off for a bit, then back on it will run normally.: VSS dropoff w/ Hi-stall converter. The rpms are too high, but VSS is showing no movement. Happens after a tire burning take-off. Doesn't store a code, will not throw a CEL (I've heard that it will store a code if it happens 3 or more times). Cure: Reprogram PCM for VSS dropoff -- PCMforLess knows about it.

If you can get the Jimmy for no more then $500.00 and the engine sounds good and body is good, you may want to invest in the repair of the jimmy. Also note that to have a close look at the fuel line along the frame on the drivers side just by the back doors, the line is know to corroded there on all the SUV's

Before guessing at transmission problems, check the fluid level (car warmed up, engine running in Park on level ground) and have the PCM scanned for trouble codes FIRST. This guide is meant for problems that do not show up as PCM codes (like shift A&B solenoid failures, for example).
Thank you for using fixya and good luck
