My local dealer said they were expecting a software update for the CLS in the late June timeframe. Does anyone know if that software update materialized and what it fixes specifically?

I'm still having trans issues (harsh shifting 1-2-3 and down) even after a valve body replacement and adaptations. Mechanic tells me it's not the clip in the cluth pack -- says if it was I'd know and need to have the car towed into dealership. Also suggested I drive in C mode...hmmm

Thanks,

-Darryl

have they found metal chippings on the oil pan?

you have to be aware that your transmission model got problem on seized bushing between torque converter and oil pump.

i just don't know how "harsh" it is.

I'll ask the Lead Tech about metal chippings.

Can you elaborate on the metal chippings and seized bushing?

Thanks!

OK YOUR CAR HAS A 722.9 TRANS IN IT. NOW IS YOU CAR SLIPPING THE 1-2 UPSHIFT AND WHEN DOWN SHIFTING IS IT BANGING THE 2-1 DOWN SHIFT IF SO THEN YOU HAVE A C CLIP POPED OUT ON B1 I HAVE DONE ABOUT 100 OF THESE C CLIP MODS I HAVE EVEN HAD THE C CLIP POP OUT AFTER I JUST DID THE MOD AT THAT POINT MERCEDES JUST HAD ME REPLACE THE WHOLE TRANS ASSEMBLY. MERCEDES CANT EVEN FIGURE OUT WHY THESE C CLIPS ARE POPING OUT. PERSONALLY I THINK IT BECAUSE THERE IS TO MUCH CLEARENCE IN THE CLUTCH PACK. HOW EVER KEEP BRINGING YOUR CAR TO THE DEALER AND COMPLAINING THEY WILL EVENTUALLY REPLACE IT.
