Sounds like this '05 has not been out to play much! The transmission lurch is a common theme with early LR3 tranny programming. There is a s/w update that will fix this. Should be covered under warranty, which has expired now. Sounds like the original owner lives in a cave. If this vehicle is on a Land Rover lot they should update the tranny software before they sell it, I think.

Not sure about the fault. I've gotten some strange transmission-related faults in my time too, but none of them have ever amounted to much (knock on wood).

Houm . . .. you're right, you would think that they would update the software during the inspection before they put it on the lot . .. . my '05 had exactly the same problem. It ended up being a bad tranny ECU module . . . .fixed under the extended warranty I bought with it.

I think my LR did live in a cave . .. .'05, 23K miles, non-smoker, was hard to pass up.

@kingfish: TSB for locking rear diff motor? Do you know the number? I've never heard of it...

Transmission MIL Illuminated with DTC P186D Stored - Repair
Procedure
AFFECTED VEHICLE RANGE:
LR3 (LA) VIN: 5A000360 - 9A513325
Model Year: 2005 - 2009
Range Rover (LM) VIN: 7A239036 - AA307231
Model Year: 2007 - 2010
Range Rover Sport (LS) VIN: 6A900129 - 7A999999
7A100001 - 9A215620
Model Year: 2006 - 2009
CONDITION SUMMARY:
Situation: The transmission Malfunction Indicator Lamp (MIL) may be illuminated along with Diagnostic
Trouble Code (DTC) P186D, and possibly P080A / P0806, being stored in the electronic rear differential
control module. The driver warning message 'Transmission Fault Stop Safely' may also be displayed and the
Dynamic Suspension may lower. These issues may be caused by the Electronic Torque Managed (ETM) rear
differential motor being energized while the motor brake is still partially engaged, resulting in mechanical wear
of the motor assembly which may lead to a stuck actuator and DTC P186D.
Action: In the event of a customer concern of the above, refer to the Repair Procedure outlined below to
replace the rear differential locking motor assembly and update the rear differential control module software.
PARTS:

Thanks Kingfish. I got one of these messages a while back (probably 6 months) and the dealer did some software flashing and may've replaced the Transfer Case Control Module. My only guess is that maybe while the message "Transmission Fault Stop Safely" was displayed, IDS showed different trouble codes than those mentioned in the TSB. My dealer service dept is quite competent so they wouldn't have missed this.

I'll have to go back to the paperwork and see if they list the codes that they read on IDS.

Thanks again.

BTW, I haven't had that issue since (knock on wood).

 

[kingfishgrapeja]

worth a double check though as the TSB is only about a year old. If the problem hasn't returned though you are probably fine. When mine went I got the message probably once a month and I could feel the diff staying locked while accellerating through turns in intersections.

Is this something that Land Rover will address out of warranty? These are the exact symptoms I'm having.
