Benefits of Tuning your Transmission Control Unit (TCU)

  • Increase clamping pressure
    • Enabling safer handling of power and less “flaring” on MCT.
  • Quicker shifts
    • truly beautiful on MCT
  • Upping tq limits to 800, 1000, or 1200nm
    • enables smoother feeling and superior performance of existing tunes by not rejecting torque due to stock TCU calibrations.
  • quicker off the line performance
    • >.3s improvement in 0-60mph and 1/4 mile

⚡ Experience refined shifting performance — TunedMercedes precision.

Description

Mercedes AMG GT (C190 • 2-Door) — Transmission (TCU) Tune

Bench-flash calibration for the AMG GT C190 2-door platform. Optimized shift logic, raised torque ceilings, and smoother drivability.

  • Faster, crisper upshifts & downshifts
  • Raised torque limits (profiles up to ~1200 Nm where applicable)
  • Improved launch/roll response & reduced “torque cutout” feel
  • Complements ECU power tunes for fuller performance
  • Professional bench-flash process with post-install support

🔒 Secure checkout
🛠️ Post-install support
📦 5–7 biz-day turnaround (typ.)
↩️ Return-to-stock available

Fitment & Compatibility

Platform: Mercedes AMG GT (C190 • 2-Door)
Transmissions (typical): 722.9 / 725.0 (verify variant at checkout or via VIN)
Notes: Some sub-variants/years may require additional steps or a different file family. We will confirm after order (VIN required).

Technical Specifications
Torque ceiling options* ~800 / ~1000 / ~1200 Nm (platform-dependent)
Shift strategy Refined upshift/downshift points, reduced lag, improved part-throttle logic
Launch behavior Stronger, more consistent launches where supported
Programming method Bench flash (TCU shipped to TunedMercedes)
Adaptation Light adaptation over first 300–500 miles; full settling by ~3,000 miles
Revert to stock Available upon request (service fee may apply)

*Exact torque limit targets and behaviors depend on your specific transmission/ECU combo and condition.

How It Works

  1. Order: Complete checkout and include your VIN and transmission details.
  2. Ship your TCU: Carefully remove and pack the TCU (anti-static bag + padding). Include contact info.
  3. Bench flash & calibration: We read, calibrate, and write your file (typical bench time 1–2 biz days).
  4. Return shipping: We ship your TCU back; you reinstall and perform a brief adaptation drive.
  5. Support: Post-install check-in; optional data review if needed.

Turnaround varies with workload and carrier transit times.

Shipping & Packing Tips
  • Use anti-static bag + bubble wrap; immobilize the connector area.
  • Double-box for extra protection; add a copy of your order confirmation.
  • Ship with tracking and insurance matching replacement value.
  • Email tracking to [email protected] with your order #.

FAQ

Does a TCU tune add horsepower?
No. It optimizes shift logic and torque handling so you can use existing power more effectively.

Will this work with my current ECU tune/intakes/turbos?
Yes—this is designed to complement ECU power upgrades and higher-flow hardware. Provide full mod list at checkout.

Is OBD flashing available?
For this platform we perform a bench flash for reliability and control. If an OBD path becomes viable, we’ll note it here.

What if my car feels harsh at first?
Some firmness is normal during adaptation. It smooths out over a few hundred miles as the transmission learns.

Can you return my car to stock later?
Yes—return-to-stock service is available (service fee may apply).

Bench Flash Note

This is a bench flash process the TCU will need to be shipped to us.

What it Does

TCU Tune does not add power but enables the power being made to translate into quicker times.  This also addresses many of the issues people sometimes have with applying power, for example in a CLS 550 4matic without a TCU tune my tires would spin and cut power completely.  After the TCU Tune it applies the power fully or with the slightest intervention.

I personally ran  TCU tune on my CLS 550 4matic, which completely transformed my car, prior my car could not apply the power the engine was making.  I also run a TCU tune on my 205 C63 which helps out a lot.  I would say she felt tame before the ECU tune, then felt powerful after that, but she felt fast after the TCU tune.  I’ve driven over 100k miles on tuned TCU between the two and she has been flawless when passing, racing, and road tripping.
