8 speed shift lock solenoid problems

I think the odds are quite high based on OS experiences with the exact same unit in LRs and Jags which unfortunately are failing with the same lock up issue at varying age/klms. I did ask LR for info on replacement rates inc numbers of new part being sold etc but they did not reply. Tilfords in Hobart said they've seen a "few" and there's not too many rotary shifters in Sthn Tas compared to elsewhere.

If the issue is a dry or defective solder joint...and all indications are that this is the cause on the solonoid circuit..moisture ..vibration..or circuit board heat could well influence how and when it goes open circuit. But then again is the new unit any better?

If I was travelling I would certainly fit an override system beforehand.. it will take an hour or two. That's all.

PS even 2004 Patrols have a button to override the shift lock should the electrics fail. Why LR didn't do that is beyond reason.

Today I spoke with my friend Alan at British 4WD at Seven Mile Beach (Tas). He sells Genuine & Aftermarket LR/RR parts to all states of Aus. Due to the fact that I tow my c/van all over Aus I am very concerned re potential failure at the most awkward time and remote location and am of the opinion it would be very cost effective for me to have an improved (?) updated (?) part fitted PRIOR failure. There have been 8 part number updates, but as he says, some of those could simply be due to changes of the Manufacturer of the component. If I could be convinced the replacement part was improved and "fixed" then I would install one without hesitation.

From reading US Jag forums I understand that LR changed manufacturer of the unit some time around 2010 after repeated failures in Jags and to address the failing diode issues. The shift lock mechanism design was changed and a known circuir board solder issue was addressed.

Various forums continue to report failures in cars post 2010 so it seems problems are continuing😐. Like us some US Jag techs are sucessfully resoldering resister joints. PS in Canada LR replaced Jag rotary controllers free of charge. In the US the Fed Agency for car safety investigated this issue resulting in LR extending warranty over the part. In Aus....zilch.

I've now written to LR UK seeking advice about these failures and remain hopeful of a meaningful reply.

How many solder connections did you re-do or fix? In Marc's original description it seemed like he soldered at quite a few. I have no experience with soldering PCBs.

Together with the stupid idea of removing the dipstick from the 3.0L V6,it says it all about LR and their silly ideas.

Another good example of dumb technology for what gain?

I soldered all of those Marc indicated.

Dumb design yes...and one that's been adopted by other car makers inc Ford Chrysler Merc and BMW some of whom have recalled cars to fix the unit.

Consumer organisations have slammed the design and deduct points from car ratings if they have them. In the US there are allegations of roll away injuries/crushings caused by the unit not selecting Park ..either automatically or if selected by the driver. Of course US drivers often don't put on the handbrake!

Mmmmm....LR UK have referred my concerns to....guess who...LR Aus of course.

This is worse than dealing with Centrelink!!

I give up😐

Apologies in advance!

Well I took my T20 Torx and the usual Phillips driver and started to follow the instructions form the PDF - removed the cup holder and the spill tray - simple - all good!

Attachment 155941

The next paragraph starts "Open up the centre console lid ..." ouch! On my 15 D4 I cannot find a 'lid' - am I missing something here? Also tried 'pulling up' on the sides of the centre console where the cup holder is - not a hint of movement.

What am I missing here?

Thanks

Read your post with a resigned smile - two things come to mind here - play dumb, and secondly, refer to your nearest dealer! Our nearest dealer always can't assist on the phone, and says "bring it in" - they've got to keep the income flowing!

Hope you got..you need to pull up and out/forward the front sides of the centre console. Be brave☺
