I guess you're right. I talked to my friend again and he corrected his statement to that this pressure should be measured first and then, if not in the correct range moved back to where it should be. His point was that if seals get old, the pressure would drop and it could be mended by slightly increasing the pressure.

Im so tired of this transmission now.
Look at the speedometer between 2nd and 3rd. The acceleration pace slows down before/under the shift. It feels like its overrevving the engine outside of its powerband or just sitting and waiting for the desired nm-value before it shiftes.

All shiftes seems to be slow and weird.

My 535D LCI with sportautomatic was totally different. The only shift that than you can feel was between 1st and 2nd. The rest was just like a loooooong power surge.

I know i posted the 535D video before but its just for comparsion.

It is also more responsive to negotiating a shift with short lifts of the throttle.

Wow!! I did not find the 7610591 but instead used the 7610590.. Damn! it´s a new car!!! it shiftes faster but the most difference is in city-driving were it shiftes a lot earlier, smoother and uses 3rd gear more instead of going down to 2nd in roundabouts etc. Also it feels like even if the torque converter does not lock up earlier it slips less under low load conditions.

Why did i not find the 7610591? Maybe it only available in expert mode?


Before update i had 7592089 so i guess that one was pretty old.

I have a 330d LCI with the N57. The engine supposedly has 245bhp (although many suspect nearer 260 as per the F30).

The pre-LCI 330d with the M57 had 231bhp.

The 0-60 of the pre-LCI is 6.7 seconds from memory whereas the LCI is 6.1. This 0.6 jump was largely put down to the improved gearbox.

I don't think it really changed. Could this just be improved software which is what you're experiencing Chris?

[ChrizLoud]

Gearbox changed around 2007/2008.
Better consumption and faster 0-60'times.
But yes, software improvments can give us better 0-60 times

Don't worry, you have the 7610591. That is the number of the daten file it uses for the assembly number 7610590. Hier is the line that puts it all together:
7610590,0000000,7591972,A,7610591DA,0FFFFFFFFFD,00 0,1 H

As for the hesitation you noted in your first video clip - that is one of the nannys kicking in when seeing wheelspin. In order to completely deactivate the nannys, you have to hold the DTC button pressed for 5 seconds until the triangle appears in the diplay.

Thanks, so this 7610591 im using is the latest possible software at the moment right?

No not talking about the "nannys". This in between shifts. It's so slow on shifting with the old software acceleration actually holds between gear changes. With the new software its much better but not even near as fast as my 535D SAT. (and also paddle reaction is still a joke)

We need to be writing to this ECU very soon before i go crazy

Correct. It's the last possible calibration. It's not even for the M57, but for the N57.

Its much better.
When coming to a roundabout it used to shift down to 2nd with locked torque converter making a big jolt if i'm not gentle with the gaspedal.
Now it holds 3rd gear and if going to slow in the round about it rather opens the torque converter clutch and starts slipping instead of going down to 2nd.. Much more comfy

Funny, thats exactly the behaviour I hate so damn much. Opening the TC in 3rd gear leaves you with almost no accelleration unless you really step in. Feels like driving a Toyota Prius.

where did u guys get this 7610591 version and how did u flash it? with winKFP?

[winnepooh]

Hello,

i´m following this post for a long time. I don´t like the transmission behavior, too.
Between 2000-3000 rpm the TC is not closed, only regulated at high load.

The dump is a 2010 320d 184hp with a alpina D3 transmission flash.

The tool needed about 27 minutes.

Thanks Winnepooh, much appreciated. Are you saying that even with the Alpina flash the TC does not close in the first 2 gears and shifts around 2000-3000?

Just used comfort mode, entered my current zb (as been seen in INPA) and the just choose 7610590 from the list.

Enter you full VIN and flash, after flashing you need to code EGS with NCSExpert (before coding my paddles did not work)

In the attachment is a log-file of the TC.

Here you see it is regulated at high load.

This weekend i can make another log file with gears 1-6.

Very interesting. Thanks! I assume that was a wide open throttle pull?
When you get a chance this weekend, would you mind doing a 30% and/or 40% throttle pull with these variables logged in TestO?

It is also a good idea to clear the adaptions after flashing a new cal.

[Mik325tds]

Today, I flashed my modified A7610591.0da that contained a one line change and has checksums corrected. As expected, the EGS was stuck in bootloader afterwards and reported a signature check error (see error1.txt).
I then tried reading the EGS with Dave's TCU_flash tool but it aborted at block #2 address 0x0E000. Sure enough, when I tried reading that address, Ediabas reported an ERROR_ECU_REQUEST_OUT_OF_RANGE (see Error_read.txt). But I was able to read address 0x10000 and above.
So what might be the reason why the EGS now blocks the range 0xE0000 to 0xFFFF?
dave205t, would you mind modifying you flash reader to accept inputs on where to read and what to simulate? That way I could try again and we'd see what else changed in Memory.

The next strange thing was this: After I reflashed the original A7610591.0da - to make sure everything is good, I set WinKFP to force program updated in Comfort mode and had bootsector update enabled - the read out has three bytes different at address 0x782B (dumps included in .pdf). If I'm not mistaken, that is part of the bootloader area since it is not contained in our 0da/0pa files.
What's your take on that?

While it's probably difficult to follow the ZF adaption reset instructions completely I think it's important to perform the reset and first drive on a fully warmed up gearbox.

Hmmm, I never reset adaptions until today. Other sources on the net tell not to mess with adaptions on a gearbox with some mileage on it?

Thanks for pointing this out. I completely missed that part of the instructions. Have you been able to perform a full adaption teach in run and if so, did it make any difference to just driving after an adaption clear?

I've been storing the adaption values before every reset and it seems they always converge to the same value range.
