Thread: Gearbox Fault - Terrain System Disabled

MadJax,

I have had similar messages, transmission Fault, limited TR and gear selections available on a couple of occasions.

Generally I found it only occurred when, like you noted I was climbing very steep hills, one time from Tom Groggin up to Mt Pinnibar in VHC for example.

My best guess is that for some reason the steep incline limits the ability of the transmission fluid to circulate properly and a long hill will make the transmission overheat and cause a failure message. I guess it is better than a massive failure from overheating.

Luckily each time I have either been close to the summit or at a place I was happy to stop and have a cuppa and after 2 -30 min of cooling down everything returned to normal and fault did not reappear.

Had it check at the dealer the first time it happened and whilst they confirmed their was a fault logged they could see no issue of problem with the transmission.

As I said my assessment is at best a guess and at worst a very bad guess but I have done plenty of miles since with no issues.

Funnily did a 2 day trip in the VHC over Christmas, climbed some steep hills but did not get the message ?

Not sure this is helpful and if you do a search I am sure there is a thread on this some time ago.

Thanks. I'll have a search and also mention it when I have my next service, but that will not be for a while as the last one was 6 weeks ago.

A few people have reported the same issue with no long term faults - maybe a temporary overhead issue.

Saw a similar warning while towing a trailer which might fit your steep climb issue. Enjoying magnificant scenery I had left my D3 in Automatic. On a long steep climb saw BING with a gear box overheating warning. Shifting to command shift 2 or 3 in low range saw no other issues. I had about 120000km on mine at that point. Now at 230000km.
Were you using command shift or auto?

I was playing around, most of the time in command shift, about 1/3 in full auto. Will see what happens next time I get off-road.

Lots of people suggest the brake controler is worth replacing as one older version of it caused lots of odd errors. Look in this post for some details I switched my brake controler. Or this post if you might do it yourself

It's not the brake "controller" they talk about - it's the brake light SWITCH.

I'll check it out, but not sure it is related. Only the gearbox fault and terrain control disabled. Everything else was fine. Suspension, HDC etc all working as expected.

Car kept climbing up the mud ruts happy as
