It seems like the engine is getting bogged down when it hits 1400 rpm. its when the car kicks into over drive. Maybe its the torque converter acting up? i need help. The car will stop shaking once i get it out of that rpm range, but if i slowly hit the gas while its shaking, it will keep shaking for a while. any help is appreciated

 

it is doing that because that is to low for the motor to pull the car in that gear. that's what....40mph? you don't need overdrive until 50mph and up.

 

now if i go tonite and it still shakes even though im not in overdrive, what could be the problem

 

doubt it will happen because with your setup(i used to have that setup) in drive at 40mph you will be turning roughly 1850-1900rpms with the torque converter locked up.
