Jerking accelerating While driving on the highway there was a slight **** that occurred when I got just over 65mph. I slowed down and it stopped. When I got back up to 65 it happened again. This happened 4 times with the jerking stopping when I slowed to under 65. This caused the cel to come on. Also when I was in park trying to check the trans fluid, the engine just turned off. It started right back up and drove. Is this a sensor, engine, or transmission problem?

**** = jeeeerk.....?
no year, stated. wow ! 1993 to present.!
only Jeep GC.
no engine stated. nor transmission option type,?
stalls, all stalls end with the CEL glowing this is NORMAL the CEL
the CEL glows at key on, for self test. and at all stalls.
if you had looked closer at the cluster ,lots of lamps glow , at self test.

the jeerking (spelled wrong to fool the stupid bad words engine)
Jeerking is usually engine gross misfire, or loss of DC 12v electical power to the EFI systems. called DC power loss or battery power lost.
if all lamps in the car work , radio, heater blower, dash lamps all work
then the DC power is ok, Head lights work at STALL.?
it's not the transmission

so its just an engine stall. (RPM was 0, is the big clue there)
engine RPM = 0 is a stall.
cause by gross misfire, The PCM does many things to stop all stalls.
but cant correct gross misfire, it cant.
top reasons on jeeps is....

or the JEEP ASD relay dropped you out)
btw: ever get a tune up this decade or every 60k miles?
if not , why not?

There are all these ways for the ASD relay to drop.
here are all ASD causes.

http://www.fixkick.com/Jeeps/ASD.html

there are tests for each drop logic path..
many are simple, did the SKIM lamp glow?
what I do after a real tune up is.

connect a scan tool and drive.
and bam, communications failure, you lost 12vdc power to the PCM.
bad 12v power. (loose fuses to PCM?) battery cable lugs GREEN?

or you get DTC errors. live or pending or freeze frame seen.
got DTCs?, BINGO.

The PCM even tells you ASD pin errors.
bad ignition coil (s)?
etc.

SOURCE: Transmission Light and Braking problem

hello . did the dealer scan the vehicle anyway , if the light was on it should have a history code safe in memory and they should check for it . it does not matter if the light when out by it self ,it just means that the fault its not present ,(it sounds like a bad mass meter its a fuel manegement sensor that when it goes bad the transmision does not know the force created by the engine and therefore it cant shift properly)

SOURCE: slow acceleration and jerking when put in drive or reverse

Just wondering if you had checked your trans fluid?
If it's at the right level I might go back to the place that did the tranny work and have a chat with them,
If your fluid is low you have to get it at the dealer, I think it is call sp5, I'll go check the bottle I have.

-will-

SOURCE: 2004 Audi A4 1.8 - jerks/jolts while accelerating from 0-20 mph

It sounds like there may be an issue with your ignition system.

Check the ignition wires, distributor cap, spark plugs.

SOURCE: car won't move, transmission fluid under car

Once an automatic transmission gets low on fluid, it won't move. Get the leak fixed, and fluid filled, If all goes well, the transmission isn't ruined.

SOURCE: Check engine light intermittently flashing, car jerking.

Could be fuel or electrical related. Since you may not know the history, this may take a while.
Any amount of smoke from exhaust? White, Blue, Black?
Start with most obvious and inexpensive:
1. Fuel filer clogged (replace fuel filter).
2. Could be the ECM (Electronic Control Module). It controls the ignition spark timing.
A few other things... consider other expert solutions...

I have a 2005 Chevy Uplander, and when driving on the highway at about 60-65, the van occasionally drops RPM's and when you press the gas harder, it recovers without any jerking or anything. The same...

This is a rare one and can be tricky. Since your rpm gauge rises back up when you increase your acceleration slightly but you feel no jerking of acceleration then this tells me that a speed/rpm senser either has a bad connecton or the sensor itself is going bad when the engine reaches an optimum heat while driveing on the highway. Since you feel no acceleration when you slightly press the accelerator down but yet the rpm gauge is increasing back to normal, the throttle body sensor may be compensating for the failed speed sensor/failed sensor connector. Please get your uplander diagnosed properly first to confim this.

When slowing down the transmission feels as if it is jerking in to the next gear.

after checking fluid level is correct, try this, to see if it improves...
into drive,let car accelerate without any gas(do not touch pedal)to max speed (about 30/35mph).stop,then with 1/3rd gas pedal,accelerate to max speed(do not move foot)stop,then foot hard to floor,upto about 60mph,then stop.then only using a max of 1/3rd gas pedal,drive for about 15miles.you have just reset the drivetrain computer setings....the car is fitted with a computer controlled fuzzy logic gearbox,it will try to make you drive as eco as poss,but if used harshly the gearchange can be harsh up and down.....
if driven gently 4th will engage at 43 mph,with a slight clunk.

Transmission Slight Jerking When Slowing & Accelerating

Have you changed the trasmission fluid and filter in your jeep lately, if not do so and that just might stop the jerking in your jeep, and if that does not do the trick you will need to have your trasmission checked out by a trasmission shop.
