THE SINGLE RAIL SHIFT OVERDRIVE (SROD) 4-speed manual transmission was designed and developed to incorporate the reliability and durability characteristics of a totally enclosed, non-adjusting, single-rail shift mechanism while maintaining the conventional 4-speed shift pattern. An additional objective was to optimize fuel economy with 3.3L, 4.1L and 5.0L engines while maintaining acceptable vehicle performance, acceleration and vehicle driveline noise, vibration and harshness. The design procedures used to obtain the design objective and to satisfy performance requirements are reviewed.
