i think my 1993 jeep Grnd Cherokee laredo is stuck in a high gear and OD does not work?
i drive a 1993 jeep grand cherokee laredo, its a 4L |6 the tranny has been overhauled about a year and a half ago...no problems until now. last night as i was driving, it was working fine until i suddenly felt it shifting at wrong times. then i pulled over and when i wanted to move again it seems like it is stuck in a high gear simply because there is low torque. engine was reving around two grand and the jeep felt like it was struggling. i also noticed that when i tried pressing OD (overdrive), the light will not turn on. but when i start the jeep it blinks once..any idea what is causing this no shift and no OD problem...could it be bad plugs/ wires? thanks in advance test drove it again this morning and still no shift...all forward gears seems like they are in high gear even when i shift it into 2 and 1. reverse works fine....going up my driveway, i could remember seeing 2500-3000 rpm and it struggles. no check engine light, and OD light wont' light up when i press it. i will be taking it back...but i did a test where u turn the jeep on-off-on-off-on then watch how many times that OD light, lights up. it shows that it might be a bad vehicle speed sensor...i will also look into it...thanks for the input guys

1 i assUme you got fluid...clean/full 2 bad battery can cause bad shifting,,,low volts upsets computer [poor thing] 3 misfire can too.i almost got a tranny rebuild because of bad plug wire felt like shifting problem 4 check engine lite on? free scan most auto parts stores [u may have prob finding one because of "old" 1993 OBD 1 computer system

For one thing, the OD light means overdrive is off. And 2500-300rpm going up the driveway means it's obviously not in high gear. Why would you not take it back to whoever overhauled the transmission?

I have a jeep grand cherokee laredo, I was wondering how the 4wd system worked?
If my tires started slipping, the vehicle would go into 4wd or is it always in 4wd even on dry pavement, also could I put a 4wd system in my jeep like what was in a wrangler where you shift.

if yours is the qudra trac II (thats what is in my jeep) when the tires start to slip 4wd will kick in and i think if you put it in 4lo it will stay in untill you put it back (not sure never used my 4lo) i dont like it i would rather have the slect trac 4wd

You would have to change the transfer case and probably a bunch of other stuff to convert to SelecTrac, which is the manual shift system.

Depends on which 4x4 system you have. Some are part time some are full time, and some are a combination of the 2. First lets start with the part time system. This system should only be used in low traction conditions such as off road, or in snow, mud, sand, etc, where the vehicle in 2WD mode cannot keep a steady forward momentum you should engage 4WD Hi range. This allows full speed capabilities with all 4 wheels being able to move the vehicle. In extreme cases you can engage 4WD Lo range if the vehicle is mired in deep mud, snow, sand, or for higher torque needed when trying to pull a heavy load. Most times there is also a neutral position which is used to tow the vehicle on all 4 wheels. The full time 4WD system allows the vehicle to be in 4WD all the time with a 40/60 torque split normally. When a difference in traction is detected by the center differential power is transferred to the axle with the most traction automatically. This type of system is engaged all the time and requires no input from the driver. Some systems include a low range 4x4 mode for the same use as mentioned under the part-time 4wd system. Also there is probably a neutral position in this system also. The combination (full/part time 4wd system) incorporates both systems into one transfer case. Allowing the driver to decide which position to drive the vehicle in. This is great for situations where you are driving in snow or ice but the road is not completely covered there may be dry spots or just places that are wet in which you would use full time 4wd high range that way you aren't shifting into and out of 4wd constantly. If conditions worsen you could shift into 4wd hi range part time and have the system "locked" into 4wd and all 4 wheels will continuously pull the vehicle forward. Along with both of those positions you still have a 4wd lo range position just as mentioned above, and also you still have the neutral position. This type of system I think is by far the greatest idea as it gives the driver the option of full time or part time usage. Also with this system you can leave it in full time 4wd high range year round if you wish. A note of advice for engaging 4WD lo range with any of the above systems, you have to have the vehicle rolling 2-3mph, shift the transmission into neutral, and move the transfer case shift lever through all positions and into 4lo. Being completely stopped will cause the system to not fully engage or not engage at all. As for a 4WD system as in a wrangler, the 4WD systems are basically the same, or offered in both types of vehicles. The wrangler's 4WD systems are just geared lower in 4wd lo range for extreme off road usage. Hope this helps, but if you have further questions please feel free to email me at wsevier@yahoo.com.

Which system do you have? 1. Select Trac (similar to the system in Wranglers) 2. Comand-Trac (A fulltime 4WD system pioneered by Jeep in the 70's)

I f you go to jeep.com and go to 4x4basics at the top of the page there;ll be a list of different things and on that list will be how jeep 4x4 systems work, simply click on that and then goquadra trac and it'll explain everthing.
