Your photographs show the controller for the 5-speed ZF 5HP24 transmission used in the ’02-’05 MY petrol-engined L322. Your car has the ZF 6HP26 transmission, where the transmission controller is integrated into the mechatronic unit in the transmission’s sump. This unit has to be coded to the vehicle, whereas the 5-speed ECU can be swapped and changed with no issues (well, other than the long-term adaptions stored in it).







How on earth did you manage to replace the ‘gearbox selector switch’, because that’s part of the mechatronic unit, too?

Hi Phil first of all thank You for answer.... Well i would like to try to describe correctly problems.... Yes my gearbox its zf 6speed. I didint change anything in land rover they change switch in shaft of gear selector... Its inside the car selector of gear swithc better to say... Now they told me that i need to change this transmission control module.... This is all this black part?! What exactly i need to change..... Its strange that today car dont start but in then next day start normaly but after 20-25 minutes he get fault mssg and errors...... Can i change just some component or whole mechatronic unit that big black part? Or its possible to put gearbox from other same model of car? Or mechatronic from that gearbox its compatible to my car? Please help me, thank You. Regards robbie

Generally, the complete mechatronic unit has to be replaced and then re-coded to the vehicle. If the issue was a hydraulic one then potentialy the electronic module (the black plastic part) could be detached from the old valve body assembly and reassembled onto a new one, which would avoid having to re-code, but your dealer appears to be telling you that it’s the ECU itself causing the issue? Surprising that an ECU should fail.




(Valve body assembly with electronic module detached)

This is great info!! I just purchased my first 06' Supercharged HSE and am trying to get it out of limp mode.
When I scan with a snapon code reader I can see every module EXCEPT the Transmission Control ...it gives me a communication failure.
I joined the forum 10min ago to find where the darn thing was located after giving up on google responses. So it is in the mechanical part of the transmission valve train.

Before I pull it out and spend $200+ in 9 quarts of ZF transmission fluid... is there anything else that could cause a "NO COMMUNICATION" between my reader and the TCU?

Where in the World are you?

I think U0102 refers to the transfer case rather than the transmission controller. U0159 is the parking assist module. Are you certain that this isn’t just a battery issue?

U0102-87 is a communications error with the Transfer case, not the Transmission. From the workshop manual;

U0102-87 Lost Communication with Transfer Case Control Module - missing message

Possible Causes

 The Terrain Response Control Module has not received one or more expected messages from the Transfer Case Control Module
 High speed CAN circuit communications failure
 Open circuit Transfer Case Control Module, powerfeed
 Open circuit Transfer Case Control Module, ground supply
 Transfer Case Control Module disconnected from the high

Actions

Using the manufacturer approved diagnostic system, check the Transfer Case Control Module for DTCs and refer to the relevant DTC index. Using the manufacturer approved diagnostic system, carry out network integrity test. Using the manufacturer approved diagnostic system, re-configure the Transfer Case Control Module. Refer to electrical circuit diagrams, check power feed and ground supplies, to Transfer Case Control Module for open circuit. Check for open circuit Transfer Case Control Module high speed CAN low circuit. Check for open circuit Transfer Case Control Module high speed CAN high circuit, Repair as necessary.
