When the fluid in a transmission becomes dirty and contaminated, the particles in the fluid prevent it from building up enough pressure in the transmission lines. In turn, this will prevent proper pressure contact between transmission plates when they are applied. As a result, the transmission will begin to shudder.
The GMC Acadia’s six-speed transmission experiences Stabilitrak system errors, shattered transmission clutches, slipping, and early failure, especially in 2007-2008 models.
Why does my GMC Acadia shake when I accelerate?
Any unusual shaking or vibrating forces coming from the engine is cause for concern. It could be something as simple as old spark plugs producing an uneven power delivery, it could be something serious like worn or broken engine mounts, or it could be even more serious in the case of internal engine damage.
An indication that a vehicle is not receiving the right mixture of air and fuel is if the vehicle jerks or surges forward at high speed. Several components of the fuel or air intake system could cause this jerking or surging sensation to happen. Issues within these systems can also cause fuel economy to worsen.

Can a clogged transmission filter cause shifting problems?
Shifting Issues
When the transmission fluid isn’t clean or is blocked by a clogged filter, the internal components won’t have the lubrication they require to function properly. This could lead to shifting issues, grinding gears, slipping transmission or other common symptoms of transmission problems.
The Vehicle Speed Sensor measures vehicle speed. When it fails the transmission can stop shifting or shift late and harsh. A bad VSS may also inhibit overdrive and the converter clutch.
What can mimic transmission problems?
Common Problems Misdiagnosed as the Transmission
