Neutral after kickdown, high revs and intermittent gearshift 722.6
Hi
After replacing transmission connector O-rings and cleaned the transmission connector, changed the conductor plate and checked the valvebody for clogging debris in valves. And visualy checked the turbine speed sensor (ISS) Input speed sensor and replaced the EGS/TCU. And reset the TCU for shifting (5sec pressing the gas pedal, turn of the key, wait 2min, then turn on the car) and later I teached the transmission where to shift and that made it better.
-But I still have a problem that the gear shifts to neutral after kickdown.
The gear shifting seems a little bit intermittent and at quite high revs.
This is the automatic 722.6 gearbox for the S430
Anyone that have had this problem and could give me just a little advice in the right direction, I would appreciate it very very much.
Thank you in advance
(even when this thread becomes old I appreciate answers since it could help other people with trouble shouting)

Seriously? Nine year old post. No answer when asked eight years ago...
First thing to do when you have shifting problems is check the fluid level. Buy the "tool" (a dipstick), and check with the engine idling and warm.

i Don't have obd tool to check the transmission temperature, so i drove the car for about 14 kms and check the fluid and it was in the middle of 80° mark (between min and max)

Model

Location (different configurations in different markets).
A detailed description of the problem. What - exactly - does the car do, or not do, and what happens when you try something.

Update
I went to the mechanic, after he plugs the diagnostic tool (OBD). He told me that there isn't any faulty transmission codes. He checked the fluid level, transmission connector (underneath the car) and everything was normal (no fluid)
We when to a test drive, but the car didn't do it.... everything was normal (so confused)
In my way home, i pushed the gas pedal (kickdown) many times, and guess what??
After many times the transmission did it again and went to neutral until 5000 RPM and then went into gear. So it didn't do this every time i push the gas pedal (kickdown)
I don't know what to do know, i think that i will live with it.
sorry for my English

It seems that you aren't willing to give us any information - We don't even know if the problem is on your E-Class, and you are posting in the wrong forum, or if you actually have a W220 (This is a W220 S-Class Forum)....
Good luck with your problem, whatever it is.

Sorry for that but i didn't notice that i haven't describe my problem here, because i posted in many forms.
I have w211 E-class with 722.695 transmission, and i commented on this post because i have a similar problem and didn't see any similar post on the w211 form.
But anyway, this is the problem:
I have 2009 w211 e200 kompressor with 722.695 transmission.
When i press the gas pedal all the way to the switch (kickdown) the transmission get in neutral and when the RPM get around 5000
It engage into a gear and start to accelerate normal.
Any idea why this happen ?
Thanks
