Lr3 transmission fault

[Liam Godfrey]

Hello everyone!

Since this bad snow every morning I’ve got into the lr3 auto it’s been a nightmare to start and it’s coming up transmission fault on the screen?? It keeps saying it’s in drive in sports mode when it is atcully in Park. When it starts the stick moves freely and selecting Park, drive and reverse? Any ideas.?? Thanks

Couple of things - maybe the linkage underneath and at the side of the gear box, could be sticking as its cold, simple to remove, clean and put back. The other is a connector alongside the lever (under the cover) which also detects where the lever is, may have corrosion, also simple to check.

Not sure what the temps are there (with snow, yes I'm sure it' cold) but mine did that during a cold snap (below freezing) and was the battery voltage. Mine stopped doing it after it warmed up. Just a thought since these things are rolling computers.

Both previous posts make good points, Have your Battery tested a weak one will work in warm weather but sucks in the cold! And these things are as Taylor made pointed out rolling computers. It gets to -20C here in Canada regularly and weak battery will show every day! An other trick I’ve found is if battery is good I turn key to position 1 and allow time usually till it stops dinging 10-15 seconds before going to start position 2 seems to allow electronics time to fire up and run its scans, when the wife drives no patience lol defaults show up! Performing my ritual corrects the issues usually thou.

I like what you say re taking time between 1 and 2. I would say that suggests a weak battery as it takes more time that it perhaps should for the computers to spin up. I think LR's computers to not have very good voltage adapters from 12VDC to the 5VDC that computers run on. As such, any low voltage in the battery is magnified in the computers - should not be but ...

About twice a year, every night I put my 3 on a CTEK battery retainer for about two weeks of nights. It takes about that length of time to get the battery back up to near full charge.

You can drive the freeways 7/24/365 and the battery will never get above 80% State of Charge - that does not make sense, but it is just the way it is.

The jpg is the gear shift lever kit - the bits rust, (see doc), and get hard to move. Fortunately, it is a do it yourself change out but not easy if all rusted. The part number is LR012704.

Is your LR3 outside? If you had a lot of snow on top and it melted and there are any sunroof drain blockages, it is possible some drops of water got into the center console and have corroded one of the electrical harnesses. In this case you will need to dig into the situation by removing the center console. Sometimes cleaning the harness is all that is required, sometimes you need to replace the shifter asssembly.

Check for wire damage under the hood and in the passenger footwell.
A relative who owns an LR3 just went through this and found rodent damage/gnawed wiring under the hood.
Once the wires were respliced all returned to normal
