Question about 1999 Mitsubishi Galant

Limp mode issues

Im stuck in 3rd, limp mode, my fuse for the reverse lights was blown so i replaced it and that one blew soon as i turned the key, i thaught it could be the reverse light switch but i can't locate it and don't know how to tell if it was bad if i did locate it, so what im asking is what could be causing the fuse blowing, oh checked bulbs and wires all ok.

You need to find out the transaxle strategy for going into
limp mode
You need a trans shop or a dealer
Have it towed on a rollback ,not flat towed or driven

SOURCE: my car won't turn over

does this car have a safety device that won't let you start the engine unless the clutch is pushed in???
if so that little switch on the clutch pedal could be faulty.

2002 dodge transmission stuck in limp mode


Well you either have a shorted component or a shorted wiring harness. Buy a factory wiring diagram booklet and follow the circuit, start disconnecting components in the system until the short goes away. If everything that the fuse powers is disconnected and the fuse still blows then you have a shorted wiring harness, look for areas where there is allot of movement or heat from the engine exhaust. You can try this site for a wiring diagram, it may have one. http://bbbind.com/free_tsb.html

Reverse light fuse is continually blowing 1999 mitsubishi galant


The speed sensor is probably the root of your problems. Likely the reverse switch wiring is routed through the harness for the sensor. That could also be the reason it goes into limp mode. Change the sensor and see if all problems are resolved. Good luck.

Wont shift ie when running 40 mph tach is 3000/ When you let off though it coasts down as normal. Check engine light has never been on. Took it to auto zone they hooked up code reader and it wouldnt power...


NOTE: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.

Also 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.

Secondly, put a line pressure gauge ($55 shipped on Ebay, or visit a local trans shop) on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.500" boost valve (easy fix in pan).

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.

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 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.

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.


Start with the simple things and check the fuse and Wire leads
at the ECM's Transmission control module and the transmission it self. Look for any damages to the wire harness and leads. Try disconnecting the wire harness form the clip on the transmission and cleaning it with brake parts cleaner and reconnect and pull the Fuse to the ECM with the ignition on the on position "engine not running" for 10 sec and place back in and start the engine and go for a test drive and see if that reset the transmission. Good luck and keep me posted, we'll get your transmission running 100% again soon.

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.

Is it starting out in 2nd. too? If so you may have a blown fuse or you tore some wires off. If the trany loses it's electrics it will go into the limp home mode. It will only have 2nd. and reverse. GM vehicles do the same thing.

98 Mirage Stuck in Limp Mode


You may not need a new TCM with any luck. I would try unhooking the battery for a few minutes to see if it will reset the TCM.
TCM = They Cost Much $. If you need to replace it you should be able to get one at a local parts house - avoid the dealership if you can. I wouldn't trust on-line stuff for this unless you know the source.

15 amp fuse for tail lights inst. pannel and o/drive blows


If it has reverse and second only it is in limp mode, something has gone wrong to cause it to do this. Sometimes you can disconnect battery and it will reset, but as soon as the problems happens again it will go back into that mode. Bad internal solenoid on transmission, slipping clutches, no power to transmission computer ie blown fuse, fauty tansmission computer. Try having some one pull the codes, if they can't it is a blown fuse or bad transmission computer. Hope this helps
