Transmission fault limited gears mode !? help

A1EK · Oct 25, 2021

Range Rover L322 year 2005 (BMW 3.0 Diesel engine model)
Miles 144K

Hi all

Up until now I have had no issues with the gear box, then today sitting at the lights, the 'transmission fail safe mode' popped up on the dash, it drove off albeit a little slow. I stopped the car, waited about 10 mins and started her up and all seemed to work okay again? However on using the car about 2 hours later after 5 mins of driving the 'transmission fail safe mode' came back on and the car had no engagement with the gears and would not move at all ! ! Also there was a slight smell of burning ?

After leaving the car for 30mins, I managed to limp home about 1 mile, having to stop a few times and turn the car off and on as I would lose the gears.

I checked underneath by raising the suspension, couldn't see anything obvious with no leaks around the gearbox pan, the gear box was warm but not roasting.

I have read on this forum that the most common issue is that there is not 14V across the battery when the car is on, however I have checked this and I am getting a steady 14.1V

Any help would be greatly appreciated.

Thanks

What volts have you got without the engine running.

I am getting 12.5 to 12.7 volts when the engine is not on, the battery is only 5 months old and starts fine.

ps. the first time the fault happened was after driving for 20 mins, so not sure why the resting voltage would be a factor?

Is there any history of any work on the gearbox, as the td6 has a GM gearbox and normally is toast at about 80k+ and needs a rebuild with a sonnax valve block and new torque converter.

Hi there, no gearbox work that I can see from the previous owners. I have had the car for 3 years and only done about 15K miles.

First thing to do is check the gearbox oil level, you have to use a set procedure to check the level.

Hi, yes I read that, getting the car to the correct temp etc. I tried to have a look at the plug on the side of the gearbox, which for me was on the left (looking to the front of car), but it was dark and I only had my phone. I took a photo, there was a plastic bung that I removed, then I took a photo inside but could'nt see any allen key? was this the wrong hole, it may have been a blank for where the transmission link went in as it was on the other side?

Thanks everyone. I was going to scrap the car as it was quite old at 2005. But the wife likes the car very much so decided that I'm just going to pay out for a complete strip down of the gearbox and rebuild @£3100 , oh well as long as the wife happy for a couple more years!

£3100 seems a tad steep. Maybe shop around.
