One thing that can cause this is a slipping automatic transmission. The clutches do not engage at first letting the engine run free, then they engage suddenly producing a slam or jerk. This will quickly destroy a transmission.
First you should Check out your Transmission oil level that could cause your car too jerk into gear. The only other thing it might be if the transmission is going bad and you should have it checked by a transmission specialist
A corroded distributor cap and rotor will cause a vehicle to be difficult if not impossible to start and may cause the motor to run rough. If a manual transmission is jerky the clutch slave cylinder or clutch may need replacing ( clutch slipping ). It would also do to check the clutch lines for leaking fluid.
Something to do with the transmission. Probably slipping It's the force of momentum being exerted on the car, the chassis of the car doesn't quite "catch up" with the engine itself without a transfer of momentum, or "jerk".
yes it will especially when the torque converter is going into lockup
It definitely is a possible cause of it jerking, if it's not an engine mount, service the transmission
There are several problems that could cause your car to jerk when slowing down. The most common cause would be a transmission problem.
The most common cause of a automatic transmission jerking, when shifting, is low transmission fluid. Fill the transmission to the full mark.
possible problems: broken engine mounts cause the engine to jerk, or tranmission fluid needs change, and possibly bad transmission.
Changing the transmission fluid in your LS should be performed by a qualified service technician. There is a fairly comprehensive procedure for servicing the transmission and it requires that the fluid be checked hot and cold. Too much fluid in your transmission will cause it to jerk when putting in and out of gear, the shifts will be choppy and it may even feel like its slipping, and finally there is an overflow valve that will cause the excess transmission fluid to leak out and onto the floor beneath the transmission. A qualified service technician will know how much fluid is enough and how to get it out.
would an automatic transmission car jerk when shifting after having had a transmission flush
Possibley, the Clutch sensor, or the transmission is going.
