The JHM TCU Tuning for your Automatic C5-allroad 4.2L makes your Tiptronic Transmission shift faster and harder. We firm up the shifts to give a clean and crisp gear change that is faster and firmer than the stock characteristics but still not too abrupt. We feel our JHM TCU Tuning makes the car shift how it should have from the factory. It gets rid of the sloppy and slow slipping of the OEM TCU calibration and replaces it with firm, crisp, shifts. This allows you to get the most out of your Tiptronic C5-allroad 4.2L by allowing you to put the power to the ground faster.

Our TCU Tuning not only speeds up the shifting on upshifts JHM also modifies the downshifting characteristics and the behavior in "Tip Mode" to make the car more performance oriented while still being very streetable. We also improve the downshifting as well, we have been told it feels "less clunky".In our development for the TCU tuning we made a few different calibrations that could make the transmission shift harder, but we found that this made the car feel too much like and old muscle car, and less like an Audi.

When you increase the power of the vehicle, the slipping and sliding of the OEM calibration will prematurely wear out the transmission. While it may be comfortable, the slipping of the transmission means that all of the clutch packs in your transmission are doing more work and slipping more, wearing out faster. The faster and firmer shifts prevent this wear by decreasing or eliminating the slipping.
