The GM Hydra-Matic was a success and installed in the majority of GM models by 1950. Through the 1950s, all makers were working on their own automatic transmission, with four more developed inside GM alone.

A Hurst stick is required (NOT included, sold separately). Other brands and homemade sticks are discouraged. Stick mount has 3/8'-24 threaded holes spaced 7/8' apart on center + mating serrations for a Hurst stick on one face. Due to larger mounting threads (3/8'-24), sticks that use 8mm mounting bolts (most OE, 'non-TKO' Lokar, others) will not work. Lokar TKO sticks can be mounted but only to the smooth side of the stub. To select the proper parts:

  • Wait until new transmission is installed to buy shifter parts
    • Remove existing shifter base if present
    • Sit in vehicle, in driving position, with all interior trim (dash, console, etc) in place
  • Define desired knob location in space (neutral position):
    • Measure height from base flange to desired knob location = overall height
    • Measure side & rear offsets from receptacle bore to desired knob location
    • See this diagram for clarification
  • Study the Hurst stick page for shapes that meet your needs
    • Allow 3-6' for stick mount height
    • Choose a stick and see what fulcrum heights are compatible with it (see chart)
    • Check overall height (see chart: stick height + mount height = overall height)
  • Confirm chosen combination achieves desired knob location and that fulcrum height works with stick length selected
    • Consider various stick & stub combinations to optimize
    • Note long sticks on angled mounts will strongly offset knob to left (can be 5-6'+)
    • Note OE dust boot is short and exposes stick mount which helps in tight situations
    • Options E & F require a Hurst stick directly mounted on side w/ serrations

  • Stick length = point-to-point distance from mount hole to knob thread
  • Stick mount height = distance from base flange to stick bolt hole (affects knob height)
  • Fulcrum height = distance from lower ball to fulcrum pin; varies by option, not published
    • Warning: Follow stick length guide to avoid excess effort & component failure
