Modified Stock Torque Converter Service
EMS modifies your stock 2015-2023 Mustang EcoBoost torque converter with the same setup that helped our world-record EcoBoost Mustang run an 8-second quarter mile. Tweaked to match your build, daily-drivable on the street, race-proven at the track.
Pick Your Transmission — 6R80 or 10R80
EMS modifies the converter to match your Mustang’s factory transmission. The 6R80 (2015–2017) and 10R80 (2018–2023) use different converter internals, so the modification work and labor differ accordingly.
| Transmission | Vehicle Range | What It Is |
|---|---|---|
| 6R80 | 2015–2017 Mustang EcoBoost 2.3L automatic | 6-speed automatic. Earlier transmission, simpler converter modification. |
| 10R80 | 2018–2023 Mustang EcoBoost 2.3L automatic | 10-speed automatic (joint Ford/GM design). More complex converter mod, more labor. |
Use the Choose Transmission dropdown above the Add to Cart button to select. Required.

This is a send-in modification service — not an off-the-shelf product. Plan for round-trip shipping turnaround (your converter to TN + return to you, typically 1-2 weeks total transit + EMS labor).
Pick the right transmission. The 6R80 (2015–2017) and 10R80 (2018–2023) converters are NOT interchangeable. Selecting the wrong transmission will result in a converter that doesn’t fit your car.
For custom configurations, new-unit + modification packages, or to confirm fitment with your specific build & tune, contact us first for a quote. Once modified, this converter is tuned for performance applications — pair with the right transmission cal for best results.
