Hi im new to these forums so sorry if i dont explain my problem correctly but hopefully you guys can help me out.
My car has a rebuilt motor because the last owner was running the car with out oil. When they rebuilt the motor the car became very shaky when it is about to shift gears it is an automatic V6. I have changed the throttle body and it seems it is getting less shaky. Now the car is still shaking but not as much as before i installed a different throttle body but it stays and shakes the same as with the throttle body i had installed before is their anything else i can do and by the way the car shifts around x2000 rpm

Check your trans fluid after you've driven on the highway for a few minutes. You're looking for burned fluid, foam, contamination, etc.

Check all vacuum lines.
