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.
