I assume it's a man. trans!! If so a certain amount of shifter shaking is normal during starting. On acceleration the shifter should move slightly do to engine torque but vibrating could be weak engine and trans mounts. There is a couple of bushings in the shifter assembly cover that are plastic and break or just wear out that make the shifter real loose and amplify the shaking of the engine trans assembly. The bushing on bottom is a half in. dia. cap type and the top is a ball socket type with a snap ring under the boot.
