Transmission Software Upgrade

Hello all,

I am new to this forum and recently acquired a 2006 BMW 750Li.

I have been having some rough transmission shifts from 2-3 gear and read countless hours online and it seems everyone is pointing to a software problem/reset adaptation with DIS/IPNA.

I really do not want to take it to the dealer as they are quoting me $350 just to update the software.

If anyone could point me in the direction to acquiring the software and proper cable to do this, I would greatly appreciate it.

If anyone in Southern California has the software and hardware to reset this, I'd be willing to drive out to wherever you are and give you some money for your troubles as well.

Any help is appreciated. Thanks in advance.

Mein Auto: 2005 745i
SUBJECT
Harsh 3-2 and/or 2-1 Downshifts
MODEL
E65 and E66 (7 Series) 745i and 745Li with N62 and GA6HP26Z transmission
Vehicles from SOP up to 03/2005
SITUATION
IMPORTANT:
Depending on the production date of the vehicle; there are different situations, and corrective measures, that
must be carefully followed. Running production changes in vehicle hardware and software divide these
situations into three distinct production periods.
A. For vehicles produced from SOP up to and including 02/2003:
***56256;***56443; Harsh 3-2 and / or 2-1 downshift when slowing to a stop
***56256;***56443; Harsh downshift when accelerating at highway speeds
***56256;***56443; "Clunk" noise during a 2-1 downshift while driving slowly to a rolling stop, or during load reversal
as described in SI B24 14 07 and SI B26 01 06.
B. For vehicles produced from 03/2003 up to and including 08/2003
***56256;***56443; "Clunk" noise during 2-1 downshift while driving slowly to a rolling stop, or during load reversal
as described in SI B24 14 07 and SI B26 01 06.
C. For vehicles produced from 09/2003 up to and including 02/2005
***56256;***56443; Harsh 3-2 downshift when slowing to a stop
***56256;***56443; "Clunk" noise during a 2-1 downshift while driving slowly to a rolling stop, or during load reversal
as described in SI B24 14 07 and SI B26 01 06.
CAUSES
EGS software calibration
Driveshaft guibo coupling deterioration for "clunk" noise complaints
CORRECTION
For Situation A: Harsh downshift complaints
1. Verify that the transmission fluid level is correct.
SI B 24 17 07
Automatic Transmission
July 2007
Technical Service
Page 1 of 3
http://www.bmwtis.com/tsb/bulletins/...p/B241707g.htm 11/9/2007
2. Perform a "Short test" and correct all Drivetrain related faults first.
3. Submit a Puma case titled "Coasting Jolt" to obtain the access code needed to complete the retrofit
reprogramming of the EGS module.
4. Start a Progman session using only V26.1.1 or higher and select "Coasting Jolt" from the retrofit options
menu. The measures plan should indicate a higher programmed number and an EGS calibration change.
5. Clear the EGS adaptations after programming is completed.
For "clunk" noise complaints, vehicles produced 10/2002 up to and including 02/2003, inspect the driveshaft
guibo coupling for deterioration or separation as described in SI B24 14 07.
For Situation B: "Clunk" noise complaints
1. Verify the complaint
On vehicles produced from 03/2003 up to and including 08/2003 the only repair is to inspect the driveshaft
guibo coupling for deterioration or separation as described in SI B24 14 07.
Note:
There are not any further EGS software changes for vehicles in this production period.
For Situation C: Harsh 3-2 downshift complaints
1. Verify that the transmission fluid level is correct.
2. 2. Perform a "Short test" and correct all Drivetrain related faults first.
3. Submit a Puma case titled "Urban Program" to obtain the access code needed to complete the retrofit
reprogramming of the EGS module.
4. Start a Progman session using only V26.1.1 or higher and select "Urban Program" from the retrofit
options menu. The measures plan should indicate a higher programmed number and an EGS calibration
change.
5. Clear the EGS adaptations after programming is completed.
For "clunk" noise complaints, vehicles produced 09/2003 up to and including 02/2005, inspect the driveshaft
guibo coupling for deterioration or separation as described in SI B24 14 07.

Hope that will help. $350 is not a bad price for the reprogramming. Let the dealer do it. But make sure they follow this procedure and you have these symptoms. I thought my tranny was going to fall out. After the SIB EGS Software calibration, all good. No problems thus so far. It has been a few months.

Hi guys,

Thanks for the quick response.

The dealership is now telling me they are not willing to upgrade because it is "not a recall problem that requires an update to the software".

How can I check which SIB version I currently have on the car and what is the latest version available for download?

They want to charge $160 for a technician to drive the car and if they feel it is a problem, then they will advise what to do next.

I have already had 2 technicians from different dealerships drive the car and for some "unknown" reason, they keep telling me there is nothing wrong with the shifting.

I can CLEARLY feel the jerking motion of the shifts but they keep insisting it is normal.

How complicated is this supposed software update? I thought they could just hook up a computer and reflash the programming easily, but it seems these dealerships aren't willing to do it.

Can this be done personally or am i just out of luck and need to drive to every BMW dealership in the area until someone finally gives in?

I'll try changing the guibo this weekend since it does not look like too hard of a job to do, but I do not hear the clunking sound as stated in the service bulletin.

Much appreciated.

Ok, update from the stealership.

They had a technician drive the car and recommended the following:

GUIBO change ~$960!! Isn't the part only around $180? that is some intense labor. Is it really that hard to change? (I have the write up on how to change it, but it doesn't seem the ~$800 in labor is not justified....)

Has anyone changed this themselves without too much trouble?

The guibo change writeup looks straightfoward enough, but is there potential hardships that could take 8-10 hours worth of labor for a change like this?


Thanks in advance.

Buy the part and have an independent mechanic change it

More details please. EGS? Progman?
Is this a DIY?
