Question about 1994 Jeep Cherokee Country

1 Answer

My 94 jeep cherokee sport with a five speed has been jerking violently through all gears from a dead stop. There are no codes showing anymore. I've replaced the tps, ignition switch, alternator, and starter. Giving further gas does not improve the situation. Pushing the clutch in and revving the motor there is no engine hiccup noises and it's not running rough. It idles normally, there is no unusual noises it just jerks violently. What could it be?

I had the exact same problem, The rear wheels have bushings that go out, they are only a few dollars. I changed that and it solved the problem. In addition I did change the throw out bearing and pilot bearing at the same time. Problem is now fixed

1999 jeep Cherokee classic. It will not go into 1st gear. It says it is the input speed sensor. Check gauge light comes on now. I replaced the alternator , input speed sensor and battery. Its over c


It says ? what says? the SCAN TOOL>?

non GRAND, (no engine stated, so fail there 1st)

my guess is you have a DTC and forgot to post that. why do that?

the DTC is covered in the FSM manual, and shows what is failing.

why not read the FSM and do what it says to do?



ill no attempt to read the FSM for you,. and that vague error.

why not log in to alldata.com and stop guessing. at parts.

there is no reason to gue$$



my guess at he DTC,

P0500"

or was it the P07xx series, all A/T errors.



P1xxx codes are factory code, got them? need all codes, not just 1 of many. and using a real scan tool not some POS autozoned junk (free)



p0500 is ASE jargon (best ) is VSS sensors.

vehicle speed sensor.



the transmission TCM monitors many inputs, and if they are bad

it can NOT shift, one such sensor is SPEED. MPH or VSS

the tail shaft all all 42RE transmission has a tail rpm sensor

when dead the cars speedometer goes dead, and the TCM

is at a lost to shift to 2nd gear, if speed is 0 all day.

a hopeless deal there.



if the battery voltage is not over 15v, its not overcharging, running.

99 is a nice jeep, id fix mine, ive had many.



the tranny has 2 speed sensors.

the front sensor does not do MPH, its just engine tranny input RPM

there are 3 RPM sensor

Engine, RPM called, CKP

tranny input sensor that tells the TCM true clutch slip at all time

and if the TCC works or not.

the tail shaft is the true speed sensor, vehicle speed, it\'s on tail shaft.



my guess, is the tail sensor is bad and you replaced the front sensor

P-0715 is a bad input sensor

P0720 and up are output sensor errors.

the 500 , is the 3rd sensor, the tail shaft sensor that runs the speedo

1st google hit.

http://www.jeepsunlimited.com/forums/showthread.php?548105-P0500-Vehicle-Speed-Sensor-Malfunction



next time post real DTCs

so we can jump on the exact part and the simple tests





the beauty of 3 sensors, is the transmission runs better

shifts better

and the OBD2 diagnostics are dead nuts, accurate.

it can see illegal gear slips (bad clutch packs) in any gear

and tell you. one of the best there.are

if you had new car, with 9speed, good luck keeping that card house going.. really.

Hi,
if its a auto transmission check for the transmission oil.I would check the oil level or do the trans service.

Why the sudden jerking?


Fuel filter clogged and or impurities in the fuel system.faulty or incorrectly gapped spark plugs.Fault in fuel electrical system.Defective spark plug wires. Faulty emission system components.Vacuum leaks at the throttle body intake manifold or vacuum hoses. I would first look at the fuel inline filters it sounds like this is the likely problem.

Violent Shaking


No check engine light on? If it jumps rapidly, then it can only be due to the transmission changing gears, or slipping clutches. Either way, there should be a fault code set in the PCM. You need to get it scanned first to know the fault code.

How can you tell what trans is in 01 grand cherokee laurado 4.0


Here is an article I found talking about the Transmission. The second generation Grand Cherokee: 1999-2004 Jeep WJ The first Grand Cherokee was redesigned in 1999, for lower production cost and greater performance and reliability; it was Chrysler's first use of an electronic bus to replace individual wires throughout the body.

Jeep five-speed automatic transmission

An all-new, electronically-controlled transmission with five forward ratios including an alternate second gear ratio for improved performance for passing and better fuel economy is available with the V-8 only, and was designed specifically for Jeeps.

The transmission features unique characteristics such as a tall, 3.00:1 first gear that gives the driver better initial acceleration. Real-time driver adaptive shifting fine-tunes the shift pattern to the driver, while an alternate second gear ratio gives the driver five forward ratios. During acceleration, second gear has a ratio of 1.67. Depending on speed and throttle position, both this gear and an alternate 1.50 second gear ratio are available for kick-down operation, making the down-shift smoother. Its reverse gear ratio is equal to the first gear ratio, to allow for heavier loads.

Other features include three planetary gear sets that combine the widest range of gear ratios available in any transmission in its class. Combined with precise step selections, this brings smooth shifts and maximum power and optimal fuel economy.

The transmission is built at the Indiana Transmission Plant in Kokomo, Indiana, in an all-new 1.2-million square-foot (110,000 m2) facility.

Have you replaced the crank sensor? There isn't really any way to test it, however it isn't expensive and it is fairly easy to replace. Good luck.

1993 jeep cherokee sport 4wd, when i start it the engine runs strong, i put my foot on the break and put it in a gear (this is in both 4wd and 2wd) and it still runs with my foot on the break, but as soon...


Will the car move at all. If you put it in gear and let your foot off brake , does it move untill you touch gas , or does it jam up as soon as wheels start to turn. I am suspecting problem with diff.
Doubtfull about trans filter.
