Shifter base for TR6060 swap from 2007-2014 Mustang Shelby GT500
Shifter base for custom conversions using TR6060 transmissions sourced from:
- 2007-2014 Mustang Shelby GT500
- NOT FOR USE IN THIS CAR! Stick is NOT offset rearward like OE & will NOT FIT in console - it would be ~17" ahead, under the dashboard...
- ONLY works with TR6060 models that have a LINKAGE COVER at forward port
- NO modifications! Simply remove linkage cover and install base (see pics)
- Shifter stick will come through floor directly above linkage cover ~19" from engine block! In most cars this is WAY too far forward (see pic). For more info click here
- For driveshaft help - contact The Driveshaft Shop
This base does NOT FIT TR6060 models that have a BLANK COVER at forward port UNLESS trans is reconfigured into one of the models listed above - a VERY difficult, complicated, expensive job that we do not recommend (disassemble trans, cut rail and change lug, interlock paddle, tail housing, main shaft, maybe more?) For Viper, Falcon, & Challenger, see the tail bases that directly replace the OE shifter (forward location not really an option).
This base does NOT FIT ANY T56 - different detent architecture requires different parts!
- NOTE: Conversion parts from McLeod & Keisler / SST etc are NOT equivalent to OE TR6060 linkage receptacle - different depth, different base
This base mounts on a 4-bolt rectangular pattern that is ~ 2.88" wide x 3.65" long; stub pivot ball center is ~1.5" below the flange. It only fits in forward location as discussed above. For tail location bases, see separate listings - these vary by model
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 | upcharge |
|---|---|---|---|---|
| A | 8" | 2.8 | vertical | default |
| B | 10" | 3.3 | vertical | +$10 |
| C | 10"+ | 4.3 | vertical | +$20 |
| D | 12"+ | 5.1 | angled 14 deg left | +$30 |
| E | 13"+ | 4.0 | angled 14 deg left | +$40 |
| F | 14"+ | 4.2 | angled 14 deg left | +$40 |
| I | 6" | 3.3 | vertical | +$80 |
- 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
