C220 cdi sport AMG 5g automatic
Transmission problems.

My 2009(may) C220 cdi sport amg has lost the ability to use the tiptronic(automatic 5 speed) gearstick and also the the paddles don't work. It will not shift gears above 3rd gear. Have replaced 4th & 5th gear solenoids and fluid and tried another TCM but no change! what action is recommended next please, regards freddie70.

You've done the right things but gearbox is still not shifting all gears well.

> Can the gearbox shift all its gears well but tip-tronic & paddles stay ineffective ?
or is your geabox shifting only up to 3rd but nothing above?

> You need to read the TCU live data with a scanner to see it's status. Then what's not happening will become obvious.

Check the conductor plate inside the transmission valve body. It's a common failure point on these 5G-Tronic boxes that causes exactly these symptoms loss of manual shifting and getting stuck in 3rd gear (limp mode).The solenoids you replaced are often fine; the faulty plate is the real culprit.
