Shifter apparatus with adjustable shift stick length and tension selection features

A retrofitable remote shifter for attachment to the actuating lever of a vehicle mounted transmission, comprising:

• a base for attachment to the chassis of a vehicle or to the housing of a transmission operatively mounted to the chassis and having an actuating lever, the attachment of the base to the chassis or to the housing being located at a position remote from the actuating lever of the transmission;
• an elongated, driver operated shift stick having one end thereof pivotally coupled to the base and rotatable in lateral and/or longitudinal directions relative to the drive axis of the transmission, said shift stick including
• a first elongated component having a first driver engagable extremity, and a second extremity;
• a second elongated component having a third extremity, and a fourth extremity adapted to pivotally engage said base;
• and
• shift stick length adjustment means coupling said third extremity to said second extremity in a manner allowing the length of a part of said shift stick, between an intermediate point along the length of said first component and said one end of said shift stick, to be selectively adjusted between a minimum limit and a maximum limit;
• and
• a linkage coupling said intermediate point to the transmission actuating lever and operative to transfer shift stick motion to the actuating lever to effect shifting of the transmission,
• wherein the adjustment of the shift stick length changes the effective throw-length of said shift stick.
