0BK Transmission (ZF 8HP-55) – Standstill Basic Settings

Application

This procedure performs the Fast adaptation (standstill adaptation) routine for the ZF 0BK 8-speed automatic transmissions with UDS-based control modules.

Note: Not all 0BK transmission controllers support this function.

Prerequisites

Vehicle stationary, engine idling.
Parking brake applied and foot brake held firmly during the entire procedure.
Selector lever in D.
Transmission fluid temperature between 50 °C and 95 °C
Battery charger/maintainer connected.
No fault codes related to transmission or engine torque request.

When to Perform

After mechatronic unit replacement
After clutch or internal transmission repair
After ATF service
When experiencing harsh or irregular shifting

Procedure

[Select] → [02-Auto Trans] [Basic Settings - UDS]

From the Basic Settings drop-down list, select Fast/Quick Adaption (IDE07217)
Click [Show Measuring Data] and add:

 - Engine speed (IDE00021)
 - Fast_adaption; cancellation condition (IDE07220)
 - ATF temperature (IDE00024)

Apply the parking brake, hold the brake pedal, and move the selector from [P] to [D]
Press [Go!] to start the Basic Setting.

During the Procedure

Engine speed will increase to about 1,200 rpm
Light jolts or lurching may occur; this is normal
The procedure typically runs for 5–10 minutes
Continue holding the brake; do not release!
Monitor ATF temperature remains within the specified range.

The Basic Setting may abort if:

Brake pedal is released or selector not in [D]
ATF temperature outside 50–95 °C
TCM not standstill-capable (engine speed does not rise to ~ 1,200 rpm)

Completion

When the procedure finishes (Finished correctly):

Engine speed returns to normal idle.
Shift selector to [P] when prompted.
Click [Done, Go Back]
Read and clear any fault codes if necessary.
Road test the vehicle, normally

Notes

Always confirm ATF level and temperature before performing adaptation.
Use official factory information if unsure whether the control module supports this function.
