Is there anyway to change this programming with CarSoft or the StarDiagnostics ?

 

What I read of the manual, NO, you can't re-programme. The only thing it looks like you can do is the "Re-Set" itself using the diagnostic equipment.

 

Why

not just reset it in your driveway using the tcm reset to factory default settings?
The transmission is adaptive and will reprogram or adapt to your driving style in a matter of days ,so going through several cycles to change shift points below 2400 rpm seem a little counter productive.Most people I teach how to reset the tcm like the instant revival the car feels and do it whenever they feel the need to sharpen things up a bit.Another reason why real Mercedes mechanics do not use snapon diagnostics
Start from the factory baseline and let your driving style set the adaptations.
ohlord:bowdown:
to adapt the 722.6 properly the un snapon way
Place transmission shift lever in lowest gear, lightly accelerate to the 2400 RPM limit(2400 rpm is needed to generate the torque the transmission needs to set the values) and
back to idle condition. Perform this 4 times.
Place shift lever in next gear position and perform the same procedure as above.
After the last gear selected position is performed, bring vehicle to a stop and allow to
idle in PARK position for at least 10 minutes
without doing the last step which snapon left out of their post graduate procedure the transmission will not accept the new parameters and all that driving and shifting and driving and shifting and driving and shifting will be for naught.
Using the default key in the ignition reset procedure with the doors closed and the climate control off is faster,and when done properly shows immediate results . Unlike the drive adapt procedure you do not have to hook the car up to the SDS to do the diagnostics to see if the transmission adaptations set properly.You need only step on the gas to prove that it worked.

THIS WORKS LIKE A GOOD KICK UP THE ASS. I JUST READ THIS TODAY AND WENT OUT AND DID IT. MY 99 E430 IS LIKE A BRAND NEW CAR. THE TRANSMISSION SHIFTS FIRMER AND THROTTLE RESPONSE IS IMMEDIATE. I KNOW IT DOESN'T GIVE YOU MORE HORSESPOWER, BUT IF SOMEONE TOOK MY CAR AWAY AND SAID THEY PUT IN A BIGGER CHIP OR SOME OTHER SNAKE OIL TREATMENT, I WOULD HAVE BELIEVED THEM BECAUSE I CAN FEEL AN EXTRA 30 HORSEPOWER, SO TO SPEAK. WAKE YOUR V8 E KLASSE UP GUYS.
ANOTHER GREAT RESPONSE FROM OHLORD."

So ohlord....to reset it 'normally' one would simply -

""Reset" the ECU by closing doors, turn key to position "2", hold the accelerator all the way to the floor and HOLD for AT LEAST 5 seconds. Turn key OFF, but DON'T take it out of the ignition. Also DON'T open doors. Wait AT LEAST 2 Minutes"

Is this correct? Going to give it a try myself...TIA.

 

While on the subject of

722.6 education.
Don't you just love the cop out from MBUSA.
In this TSB
"GROUP 27 -ALL MODELS WITH TRANSMISSION 722.6:
Please check the transmission selector lever switch before replacing a valvebody
or control module for a transmission shift complaint. Diagnostic code 114 may
not set for intermittent contact, therefore it is very important that the HHT is
connected before the first start. The technician should view the Actual Values
screen and note the value while driving and manually shifting.
If the shift selector actual value reads "F", then it is defective and should be
replaced. The DTC can then be viewed but will erase with the next key cycle. A
similar complaint of no shifting or late shifting may occur if any form of liquid
contaminates the switch. Liquid contamination is not a warrantable defect."

Now they are trying to woo us back with fancy commercials in the summer of Love event.How about facing up to a serious defect and making good on it.
That would get more results from the legions of former owners that left the make.
:bowdown:
Might even get me to consider getting a Black Arrow 0-186mph in 24 flat

Ohlord, Yes, My Boo-Boo, leaving out such an important step of "Waiting 10 Minutes". I realized it in my sleep last night, and corrected this a.m.

The reason I did the more "complicated" method was the E320 still didn't have the "feel" I was looking for, even after MULTIPLE attempts at the "Default" Reset method.

 

Climate control

off,doors closed,radio off.Turn key to on position(not start) just to the position that all the lights are lit up on the dash.Press your foot to the gas pedal to the floor.(the reason you don't want it running)Hold for 10-20 seconds,turn key off with foot still on the floor,now slowly lift off the pedal and sit for two minutes before removing the key and exiting the car.Then when tempted go for a ride:thumbsup:
This procedure will set the factory shift points and rpm in the TCM to crisp settings.The harder you drive the car the less noticeable the change,but most people with a v8 will really get a charge out of the instant tune up.,a v6 will feel like chirping the tires.

10 minutes wait on the custom program It's easier to reprogram my Toshiba portege 3500

 

Is there any indication that its been reset ?

No kidding!

Just did the reset, I wish I had done this before. Perhaps due to my spending a fair bit of time commuting, my tranny has always seemed sluggish to respond, esp. when I need it. After doing this though, it feels significantly better! Wow!

You're not kidding about feeling like an 'instant' tune-up. The car feels far more responsive and I chirped my new Michelins accelerating on dry pavement in second gear, which caught me off guard. In a good way. :thumbsup:

Thanks guys.

 

hey does this work on my 95 E320 .........

 

and what about the mpg issue?????? if i do this reprogramming on my w210 E320 '2000....

is my gearbox 22.6 on my 2000 w210?( i have the tiptronic version

 

you guys realise that this will eventually adapt out? Transmission probably monitors torque from engine, more torque = more agressive driving style = shift a bit higher, so after you do all this...all you need to do is drive like a granny for a little while and you're back to old shifting points.

 

I am sorry to ask such a lame question, but on the diagram Ohlord has attached there is a switch(gear selector box) that is labeled s16/10 on it. What does selecting the w or s do?

 

owners manual describes w/s in detail. basically w (wet) position starts in 2nd gear, limits rpm, lowers shift points (rpm) and limits engine power to help avoid wheel slippage. S (or standard) position starts in 1st, and allows shifts @ max rpm. Also in the w position, Reverse is a taller (lower numerically) gear ratio than in S position, to again help on wheel slippage.

aka winter/summer position.

 

Wow!!! I did this to my E430 sport yesterday evening, and what a difference!!!

 

good to know it works. i plan on doing it sometime this week, and i will post results. mine shifts fine, but just like g-amg mentioned, the 1-2 gear change is that i never been completely satisfied.

 

Hi Tirona, this certainly work, I tired 2 months back after reading another thread here. I use simple method as ohlord described and the car is as new. I am doing it once a month.

 

Thanks Tirona.

 

isn't there a way to turn off the adaptive feature altogether and just use the factory defined shift points?

 

I am afraid not.

 

I like the way the transmission works. It is superbly smooth if you drive gently, but steps things up a little when you are not. The delayed upshifts really help in spirited driving in the mountains.

Of course, if you aren't satisfied with the results at anytime there is always the "SCREW YOU" kickdown button at the bottom of the throttle travel...

 

thank you for the info. i have been impressed with the smoothness of the shifting on the 722.6 trans in my 300 turbodiesel. torquey as heck, but smooth nonetheless. in fact, when i tap OD down to 4 to pass, i don't even feel the up-shift. i only know it did it by looking at the rpm change. wow!!!

cant wait to get my problems out of the way and try this instant tune-up thanx
