Spicer 7041 (auxiliary)
7041 (auxiliary) is a 4-speed manual transmission created by Spicer and used in Chevrolet and GMC cars.
Auxiliary transmissions are used in combination with the main transmission where extreme grades, big payloads and widely varying operating conditions require a broad range of closely spaces, even gear steps.
The Spicer 7041 4-speed auxiliary transmission combines low gear ratios necessary for heavy-duty off-highway usage with closely spaced gears and on overdrive gear needed for efficient on-highway empty operations.
Three power take-off locations located on the sides and on the top facilitate easy accessory power hookups. All gears are helical constant mesh for easier and quieter shifting. Shafts and gears are precision machined and carburized for resistance to wear.
Usually this transmission requires 8 pints of lubricant.
