Product Details

The ACDelco 19258701 is a GM Genuine Parts automatic transmission reaction sun gear shell, also known as a sunshell. This critical internal transmission component is part of the planetary gear assembly and plays a vital role in enabling gear ratio changes and smooth power transfer throughout the transmission.

Key Features:

  • GM Original Equipment (OE) quality - designed and engineered to GM's rigorous standards
  • Direct replacement for worn or damaged sun gear shells
  • Surrounds the sun gear and meshes with planet gears to facilitate gear changes
  • Essential component for proper transmission operation
  • Manufactured to meet GM specifications for fit, form, and function

The sun gear shell is a hardened steel component located within the planetary gear assembly of automatic transmissions. When this part fails, common symptoms include loss of reverse gear, slipping in 2nd and 4th gears, or harsh shifting. As a genuine ACDelco OE part, this sunshell ensures reliable performance and proper transmission function. Professional installation and transmission disassembly is required for replacement.
