2006 CDI Transmission Upgrade Blue Top Solenoids
The information is easy to verify if you do not think the information is accurate on lots of forums across 3 car brands easy to look upon the device you are reading this message on .
Most people just cut the CAT down pipe get a tune and call it a day. Better to start with things that work . They are cheaper than a Trans Tune and more effective .
Mercedes started making these STANDARD for later year E55's and high performance cars in the last 2 -3 years of production as a way of making the transmission better performance .

You can feel the car get into gear even before the Tach for the transmission changes lol. The down shifts were only hard at first the car TCU adapts and is not bad feels like a smooth manual .
The C mode is still smooth but improved .
NO DOUBT Night and day difference and I do not feel a $1000 Valve body would give me better results at this power level and was worth the $230 in solenoid parts that I paid . Will recommend anyone do this who is looking for SOLID results
NO DOUBT IN MY MIND NOW .. FASTER FIRMER SHIFTS ALL DAY>
