The car slipps or jerks in the low gears

When you say it "jerks," this description could fit several actual symptoms. If by "jerks" you mean the engine misfires, it could be caused by the need for a major tune-up (including plug wires and distributor cap), or it could be a problem with fuel delivery, contaminated fuel, or defective components in the fuel system.
I assume the CHECK ENGINE light is on (and has probably been illuminated for some time now). Begin by doing a readout of the stored codes, and use the results to begin your diagnosis.
If by "jerks" you mean the transmission is slipping (engine revs but car slows down or doesn't accelerate), you have a transmission issue. If the transmission fluid and strainer/filter have not been replaced within the past 5 years or 50,000 miles, have a complete transmission service performed.
If by "jerks" you mean that the steering wheel wobbles or pulls, you have a problem with the front suspension.
If by "jerks" you mean that the car shudders or pulls when you apply the brakes, you need brake work.
I think I covered all of the "jerks." ;)

its kinda hard to tell what the exact problem is with all the***'s but it sounds like you might have a loose gear in your trxmission, need a little more info tohelp you on this one but also check the transmission fluid and maybe get it flushed and replaced if you have anymore information please let me know and i will get back to you as soon as possible

is the motor missing or is the transmission slipping. if the motor sounds in time then I would say look at the transmission.

Not on that old of a car, Transmission is slipping, Does the transmission fluid look darker then usaul, Or smell burn,t, If it is real dark in coulor or smells burn,t, End has never been changed in that old of a car,Transmission need to be (Rebuilt)

Your transmission is most likely slipping, you can get anti slip fluid at your local parts store, be sure not to overfill, you may be low on transmission fluid check the level. If this does'nt help there could be significant damage to the transmission. Motor mounts can have the same affect you can have your local mechanic inspect them. Usually a mechanic will check the motor mounts for little or no charge.

no but a low fluid level could cause a slip telling the ecm there is a slip top it off then clear the code and drive a few miles if this code comes back i would say there is internal damage to the tranny

check atf fluid.

sounds like the crank angle sensor. my 1993 buick was doing the same thing. hope this helps.

you have a transmission that is slipping, it is going to need a teardown and overhaul.
