CO SHIFTER GM 4L60 BLACK 6' STRAIGH

The GM 4L60E (and its mechanical predecessor, the 4L60, which evolved from the 700R4) is an electronically controlled, four-speed automatic transmission designed for longitudinal placement. It was introduced for trucks in 1993 and cars in 1994, becoming a staple in GM's rear-wheel-drive lineup. The "E" denotes its electronic shifting capabilities, managed by the vehicle's powertrain control module (PCM) or engine control module (ECM).

Key features and specifications:
* Dimensions: 21.9" long (main case, excluding bellhousing and tailhousing).
* Weight: 146 lbs (dry), 162 lbs (wet).
* Fluid Capacity: 8.4 quarts (9.64" torque converter) or 11.4 quarts (11.81" torque converter) of Dexron III or Dexron VI fluid. Deep pan versions may require up to 14 quarts.
* Input Shaft: 30 splines.
* Case: Three-piece cast aluminum alloy (bellhousing, main case, tailhousing).
* Distinguishing Features (Late 4L60-E, 1996-2010): Removable bellhousing and a six-bolt "hex" rear output/tailhousing/adapter pattern (earlier versions had a four-bolt square pattern).
* Electronic Compatibility:
* 1994-1995 are generally interchangeable.
* 1996 and up are electronically compatible with Gen 3 LS systems.
* 1999 and newer are ideal for direct bolt-on to Gen 3 LS/Vortec engines.
* 1996-1998 models may require a dished flexplate and crankshaft spacer for use with LS engines due to different input shaft lengths.
* 13-pin transmission connector: Typically found in 1996-2006 models.
* 15-pin transmission connector: Typically found in 2007-2008 models, includes input speed sensor.
* 17-pin transmission connector: Typically found in 2009+ models.
* Variants: The 4L65E, 4L70E, and 4L75E are strengthened versions sharing electronic architecture, designed for higher torque applications in heavy-duty trucks, vans, and some performance cars.
