Consumer Description

Torque converter shudder and noise (definitely and issue related transmission). Around 1,500 RPM the vehicle starts to experience the shudder, shaking, and noise. Additionally there is a feeling of a surge in power, like if the vehicle shifts to an upper gear un intentionally, the vehicle launches forward occasionally (lurching forward). There is absolutely no issue while the vehicle idles, not at low or high RPM. The issue only occurs while the vehicle is in motion and at around 1,500 RPM. Using a V4 to V8 delete (Range Technology RA003B AFM/DFM Disabler) helps the issue significantly but it's still an issue. If that disabler is removed the issue is extremely pronounced. I purchased this vehicle as a used vehicle. I wouldn't have purchased the vehicle if I had the slightest idea of such a major issue with the vehicle.
