Automatic Transmission Mount for GM Applications

Key Features

  • Sure-Fit System application testing for vehicle-specific installation fit
  • High-grade metal housing with corrosion-resistant coating

  • Part number: 621035

Detailed Description

Pioneer Cables 621035 is a replacement automatic transmission mount designed for GM cars and vans that use a subframe-mounted transmission support. The mount uses a durable metal housing and application-specific rubber bonding to help isolate drivetrain movement and reduce harsh vibration transfer. It is a practical choice for drivers servicing a Chevrolet Impala transmission mount, Buick LaCrosse transmission mount, or Pontiac Grand Prix transmission mount where original support has worn out.

This part is compatible with 1997-2011 vehicle applications across Buick, Chevrolet, Oldsmobile, Pontiac, and Saturn models. The part number 621035 is also a useful search term when sourcing a replacement automatic transmission mount for GM platforms with the listed fitments.

What It Helps Address

  • Excessive drivetrain vibration felt through the cabin
  • Worn or collapsed transmission support
  • Movement or shifting of the transmission under load
  • Noisy contact between the drivetrain and surrounding mounts
  • Replacement needs after rubber deterioration or housing corrosion

Installation Notes and Tips

Verify the vehicle year, make, model, and notes before ordering. Fitment includes applications such as 2009-2011 Chevrolet Impala Heavy Duty w/VVT, 2009 Chevrolet Uplander Heavy Duty w/VVT, and 2008 Pontiac Montana Mexican Van. Confirm the mount location on the subframe and transmission mount bracket before installation. For search accuracy, use Pioneer Cables 621035 along with the vehicle-specific fitment details.

Quality Assurance

Pioneer Mounts use the Sure-Fit System, which relies on application testing on vehicle-specific fixtures to support proper fit. The mount housing is built from corrosion-resistant metal or cast aluminum depending on application, with rubber bonding selected for the specific vehicle use.
