WHAT DOES A TRANSMISSION TUNE DO?

Stock transmission tuning on the automatic VW 2.5L engines limits the RPM range and greatly reduces the available power of your rev happy 2.5L 5 cylinder engine. IE's TCU tune has been carefully set up to offer you the full performance benefits of ECU tuning and hardware upgrades such as the IE Intake Manifold by safely increasing the available RPM limit. The result is a fully unlocked power range offering the entire performance capability of the 2.5L engine on your automatic transmission.

PERFECT FOR ANY TUNE STAGE

IE’s TCU tune is all-inclusive and does not offer expensive upgrades. That’s right, there are no unnecessary upgrade charges and all features are included from the outset. The purchase of this tune offers all features for every Stage of ECU tune with no fee or upgrade cost when going from Stage 1 to Stage 2 Intake Manifold Tunes. Transmission tune requires a matching ECU Tune, do not install on stock ECU tunes. 

USER ADJUSTABLE SHIFT LIMITER

The purchase of an IE TCU file grants you access to customization of shift points. With optional RPM limits to choose from you can pick what works best for your setup! 6800 RPM limit is commonly paired with Stage 1 ECU files while the 7100 RPM limit completely unlocks the massive power gained in the upper RPM limit when paired with our Stage 2 ECU Tune and Intake Manifold.

Available Shift Points:

  • 6800 RPM
  • 7100 RPM

IE TCU TUNE TECHNICAL FEATURES

HIGHER SHIFT POINTS
Utilize the whole powerband of your 2.5L engine without the transmission interfering and shifting early.

ALLOWS USE OF IE INTAKE MANIFOLD
The IE intake manifold is a popular upgrade for owners looking for the full power potential from the stock 2.5L engine. Until now, the power was completely limited to manual transmission cars only as the automatic trans would shift before the power gains in the higher RPMs could be utilized. Now you can join in the fun on your own automatic 2.5L vehicle and rev happy adding up to 47HP & 38TQ when paired with an IE Manifold & Stage 2 Tune! (IE Manifold is not compatible with vehicles equipped with hydraulic power steering)

INCREASED POWER WITH ECU TUNE
Increasing the RPM limit allows your matching IE Stage 1 or Stage 2 tune to make power higher into the RPM range fully unlocking the hidden power available at higher shifts.

FLAWLESS OPERATION WITH IE ECU TUNES
IE TCU and ECU Tunes were developed side by side on our in-house dynamometer. By running both tunes you will unlock the full potential of your 2.5L 07K engine and transmission.

IE POWERlink DIRECT PORT FLASH TOOL
IE's POWERlink direct port flash tool is required to flash your ECU (engine control unit) or TCU (transmission control unit) and is available separately. The POWERlink tool is sold with all new IE ECU tunes and can also be used to flash your new DSG tune. If you already own an IE POWERlink unit, purchasing this file will add the credits to your cable within one working day. If you do not own a POWERlink cable, please chose to add one in the drop-down menu above.

IE POWERLINK FEATURES:

FILE SWITCHING
The PowerLink cable allows for map switching without making a trip back to an IE Software dealer. This allows you to test different TCU maps and features such as shift points.

EASY OPERATION
Simply plug your IE PowerLink cable into your vehicle’s OBD-II port and the USB port on your Windows-powered laptop to use the included IE Flash Wizard software. The flash wizard will then walk you through the installation steps.

FLASH MULTIPLE CARS
Have a friend with a compatible VW or Audi? Share the power with up to 5 different cars with a single cable. Just add enough credits to your cable for the desired tune and power-up your entire crew.

RETURN TO STOCK ANYTIME
With the IE PowerLink, you can return your vehicle back to original ECU or TCU programming at any time.

EASY UPDATES
IE will always provide free software updates as they become available and easily reflashed through your IE PowerLink cable.

Worth every penny

I love how if I want to raise or lower my shift points this tune allows me to do so freely. Combined with stage 1 ecu I've been able to keep up with the standard bullies of the street pick ups and BMWs..im looking forward to see how going stage 2 will improve it

the best investments

Just recently purchased the tune for the transmission and my God it made a huge difference not only that I have the stage 1 tune it was okay but once I put the transmission I didn't think it was going to make any much of a difference but holy crap huge difference very impressed the car definitely drives a lot better now. will recommend if you do the tune to the 2.5 yes do the transmission with it you won't regret it

Finally a tune for the AQ250!

Paired this tune with Stage 1 ECU tune for my Auto Jetta 2.5 MK6 and it was well worth it. If you are looking to make your daily driver a more enjoyable experience then this tune paired with either the Stage 1 or Stage 2 tune (only with IE intake manifold and if you have electric power steering) is perfect for you.
