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
