I have an E90 LCI 330D with a ZF GA6HP26Z automatic transmission.

Anyone got procedures on how to reset the adaptations and perform the relearning process?

I have searched and found nothing specific (or credible) enough.

Hi Arnie,
I have Ista+ and a kdcan cable, and after changing my transmission oil, I reset the adaptations through ista+

That's great. I'd like to know how though.

ISTA+:
-go to Operations;
-Read out Vehicle Data - Complete Vehicle Identification
-Vehicle Management
-Service Function
-Powertrain
-Transmission Control
-Adjustment or can do Oil Change Function
-Display and Reset Adaptation Values
-Perform ABL function

Hi,
Got the cable from Bimmer Geeks. the link below has the files for Ista+.
https://mega.nz/#!a1wUmYCD!G0C3_Hsg9...o9uQ4EpxjI8oZs

you will need a laptop, bought a $200 dell refurb dedicated laptop for this.Beware though, it's not a single click .exe file and some software competency is required. I can assist or someone else in this board if you hit any snags as I have found help here before.

Tips to anyone having issues in Win7 sp1 ISTA install:
-Make sure that BMW Standard tools is installed before you install ISTA
-since windows 7 has .net framework 3.5 within it, download and install all the later versions - 4.0, 4.5, 4.51, 4.52, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2

Thanks.

Any guidance on the relearn procedure?

Just ordered the cable.

Reset Adaptation = Relearn

Technical functionality vs general or non technical terminology.

What made me curious, Ken, was different documents and posts had made separate references to resetting the adaptations AND performing a relearning process after the reset. I couldn't find one that specifically mentioned the 330d model though (hence my query),

For example:

The Adaptation reset clears the offset values from the baseline.

TCM Adaptation (Relearn procedure) is required when the TCM, torque converter or mechanical repairs have been performed to set the baseline.

As with the terminology used, adaptation, the transmission will continuously 'adapt' to driving style so it is not necessary to clear the offsets as the transmission will 'adapt' over time.

cant you just do this using the MHD app under the codes section?

I would personally advise against being obsessive about resets and recalibrations unless there is actually an issue or repairs have been done. I understand it is human to be curious but this is one of those things where it can get out of hand.
The adaptation reset in ISTA is mainly to do with the solenoid valves, the friction components inside and the ageing of the oil and the ageing of the solenoids themselves.

Ken's ISTA instructions are great. I would add to take a photo or screenshot of the current values just for your records because the figures can give some insight to the health of the transmission.

I am curious to know why yours has the 26 tranny and mine has the 28? They are both the same in every other way?

I don't know if this helps, but according to Ken Oath:

'Generation 1 was from 2000 - 2005 and are referred to as ZF6HP19/26/32 by ZF
Generation 2 was from 2006 and are referred to as ZF6HP21/28/34 by ZF

Generation 2 6HP26Z (TU) BMW designation was the introduction of the changed valve bodies (E & M shift) that provided better fuel economy, halved shift times etc. and then later in 2007 BMW introduced CANBUS.'

Thanks for the reply, I understand all that but it still didnt explain why yours and mine have different trannys as we are both the same year. Could it be because mine came from Germany and not South Africa and other places that I have seen they have been built.?
