Hi,

I have a 2000 CLK 320 with the 722.6. yesterday the transmission shifted fine in all gears except 4th, which it went into neutral. However when it was driven for about 15 minutes it would shift into 4th with a little shift flare.

Today I cleared the codes and did a reset with the pedal, took it out and it shifted every time even when cold but has a 3-4 shift flare.

My 3 tranny codes are :
P136 SPORADIC FAULT IN CONTROLLER AREA METWORK COMM WITH EIS
P146 SPORADIC IMPERMISSIBLE TRANS RATIO
P147 SPORADIC GEAR IMPLAUSIBLE OR SLIPPING



Any ideas?

thanks
