hi,

sounds like a vacuum leak, injectors clogged, bad plugs, plug wires or maybe low tranny fluid or combo one all, have it dynoed to save yourself some money of course.

good luck

HI MY NAME IS JUAN:
I HAVE A 93 BUICK SKYLARK CUSTOM
AND I HAD THE SAME HESITATION.
I CHAGED GAS FILTER, AIR FILTER, AND USE SEA FOME IN MY GAS TANK AND USE IT ALSO TO CLEAN THE INTAKE SYSTOM, AND IT HELPED ALOT. TWO MONTHS DOWN THE LINE HADE THE SAME HESITATION AND IT WAS ONE OF THE INISION COIAL PACK WAS NOT GIVING THE ELETRICAL SPARK TO THE PLUG. I CHECK IT BY PULLING THE CABLE OFF THE SPARK PLUG WITH THE CAR RUNNING AND FOUND THE ONE THAT WAS NOT GIVING SPARK. I REPLACED THE PACK FOR THAT CILINDERS PLUG AND THE PROBLEM WAS GONE.
HOPE THIS CAN HELP YOU.

I just had the bearing between the drive shaft and transmission changed and the humming stopped. the first half of the drive train is connected to the second half and there is a sealed unit with a bearing in it. the whole shaft needs to be replaced, you cannot just replace the bearing.

SOURCE: my car jerks when changing gear what do i do

theres most likely a bad sensor located somewhere on the transmission.

Determine whether the jerking is engine or transmission related. One way to determine if it is the transmission lock up converter is acting erratically is to down shift out of OD. And see if jerking persist. If it goes away suspect transmission to have problems with torque converter or TCC solenoid . If it doesn't go away determine whether or not the engine sounds to be misfiring. If so vehicle may require a tune up. Many vehicles can be diagnosed for free at your local Auto Zone.
