Zdravím ,
máte někdo zkušenost s odstraněním problému podřazování z 2st do 1st když auto dojíždí ke křižovatce? Na začátek. Měl jsem dvě převodovky a časem to začala dělat každá. Druhá převodovka řadí bez problému , žádne škubání , řazení není cítit , byl vyměne olej a hardy spojka , nahrán nový soft včetně adaptací. V USA na foréch se to řeší hodně a údajně co pomáha je naprogramovat přes diagnostiku program konkrétně "URBAN MODE" Víte někdo o co se jedná? Má to být městský program, který právě tomu zabranuje . Mám pocit , že to uplně není problém v převodovce protože po výměne váhy vzduchu a vzduchovích filtrů se to hodě omezilo a třeba z 10 zastavení je cítit podřazení jednou. Údajně tento "urban program" by měl držet 2st a ne během pomalého zastavení dát pokyn k zařazení 1st když je auto ještě v pohybu a pak je cítít tohle podřazení. Když se řadí na volantu přechod z 2st do 1st není vůbec cítit.

E65 6HP26 750, 745 Podřazování 2-1
Tady dle toho záleži na roku a postup co by se mělo udělat
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:
�� Harsh 3-2 and / or 2-1 downshift when slowing to a stop
�� Harsh downshift when accelerating at highway speeds
�� "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
�� "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
�� Harsh 3-2 downshift when slowing to a stop
�� "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.

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.
