  • Valve Body Failure: A malfunctioning valve body can affect shift patterns and cause harsh shifts.
  • Recalls: NHTSA Recall Number: 11V-334
• 6L90-E 6-Speed Automatic
  • Delayed Engagement: The transmission may delay engagement from a stop or hesitate when shifting gears.
  • Solenoid Issues: Electrical problems with the transmission solenoids can cause erratic shifting or loss of gear engagement.
  • Input Shaft Bushing Wear: Premature wear on the input shaft bushing can lead to noise and vibration while driving.
  • Recalls: None Found

Suspension

• Front Stabilizer Link Wear: The front stabilizer links may wear out prematurely, causing clunking noises and reduced stability.
• Rear Leaf Spring Sag: Over time, the rear leaf springs may sag, reducing load capacity and affecting handling.
• Shock Absorber Failure: Worn or damaged shock absorbers can result in poor ride quality and handling.

Electrical

• Battery Drain: A parasitic battery drain may occur, causing the vehicle to fail to start.
