Abstract
A system for lash reduction of a shifter for a manual transmission includes a shifter assembly having a housing, a shift lever and a shift lever guide device positioned in the housing. The guide device includes a plurality of shift channels connected by a select channel and defines a shift pattern for the shift lever. The transmission gate guide includes a corresponding plurality of shift finger slots connected by a select slot and defines a pattern for a shift finger of the transmission. Movement of the shift lever into one of the channels operatively moves the shift finger into a corresponding one of the slots. Each of the channels includes a channel width complimentary to a width of the shift lever so as to substantially reduce lateral free play of the shift lever when received in the channels while allowing longitudinal motion of the shift lever in the channels.
