Stock slushbox leaving much to be desired?

We at GMP now offer Kleemann's Transmission Control Unit upgrades, which revise the factory programming to make it shift quicker, handle more torque, and put the power to the ground more effectively.

Programs are available for most 5-speed auto equipped cars, and the unit itself must be sent to Kleemann for modification. But to make it easy for you, we will send you the shipping label once your order is placed.

So all you have to do is remove the TCU (contact us for instructions), package it up, place the printed label on the box, and drop it off for transport. We take care of arranging the shipping, placing the order, and making sure the TCU gets back to you with its new binary goodness within.
