DIESELR EZ Lynk Transmission Tune File (2023-2025 6.7L Ford Powerstroke)

The EZ Lynk Transmission Tune Powerstroke is built for owners running custom engine files but still relying on factory shift logic. If your 2023–2025 6.7L Powerstroke is calibrated under the hood but unchanged in the transmission, you’re missing out on better control, cleaner gear changes, and steadier torque delivery.

This file is built specifically for the 2023–2025 10-speed and installs through the EZ Lynk platform. It uses the stock transmission control module—no unlock, swap, or hardware modifications required. The goal is simple: more consistent shifts, better throttle control, and a truck that behaves the same under load as it does empty.

Key Features

• Works with the factory TCM – No unlock or replacement required
• Refined shift timing – Reduces hesitation and gear hunting
• Better torque handling – Keeps torque transfer stable during acceleration
• Improved towing behavior – Holds gears when the truck is under strain
• Predictable drivability – Smooth, steady shift patterns
• Designed for pairing with DIESELR engine tunes

What’s Included

Transmission Calibration File – Tailored for 2023–2025 Powerstroke trucks. Adjusts shift firmness, reduces flare, and improves converter lockup for towing, throttle response, and everyday use.

Why DIESELR TCM Files Stand Out

• Built to line up perfectly with DIESELR engine tuning
• Faster, cleaner gear changes under load
• Less unnecessary downshifting when towing
• Stronger torque control without stressing the drivetrain

Important Note:
This file does not pair with 2026 model-year trucks.

The EZ Lynk Transmission Tune Powerstroke brings your Powerstroke’s 10-speed in line with your engine calibration, giving you consistent control in every gear and every driving situation.
