Shifter base for Getrag 238 6 speed swap from Dodge Dakota or Ram

*** For OE replacement see the complete kits instead. ***

*** Pics are of a different base to simply show the type of part you are buying. Large dust boot is not used by this base ***

Shifter base for custom conversions using Getrag 238 6-speed transmissions sourced from:

  • 2005-2009 Dodge Dakota
  • 2006-2009 Mitsubishi Raider
  • 2005-2008 Dodge Ram 1500 - except SRT-10
    • NOT FOR USE IN THESE VEHICLES - see complete kits
  • ONLY FITS Getrag 238 manual trans found in these trucks - sales code DEJ
    • NOTE: There are two base locations on case; forward position is for Ram, rear is for Dakota. Both use same base type however it is not trivial to change location as shift rail is only machined for one position
  • Lower bushing cup not included; reuse existing or buy separately

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"+)
    • Options E & F require a Hurst stick directly mounted on side w/ serrations

Stub fulcrum height options (critical to optimizing leverage for short throw):

Option For stick length stick mount height stick mount angle
A 10" 4.2 vertical
B 12" 4.7 vertical
C 12"+ 5.7 vertical
D 14"+ 6.5 angled 14 deg left
E 15"+ 5.4 angled 14 deg left
F 18"+ 5.6 angled 14 deg left
G 8" 4.6 angled 11 deg left
6" 3.9 vertical
  • 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
  • Core Shifters OE kit for Dakota uses B, Ram uses E
