I had "problems" with TC in Discovery 2 only in deep snow and deep sand - it was necessary to give it more gas, because combined resistance of deep snow and TC braking was too much. So small move back and a bit more gas was all that was needed. Sand or deep snow requires lot of engine power, and TD5 is not overpowered. Now with 3 lockers I use TC lighs as indicator, that I had to swich on some lockers already.
ABS on slippery icy hill is somethink really terrible, but this is not only LR problem. "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo Smile

Some interesting comments here, shows who really off roads hard rather than muddy field, gravel track stuff.


Very much so. I suppose I am talking from experience of the more extreme end of the spectrum rather than the basic day to day.

There is also a reason that many other cars have the ability to turn the TC off, because sometimes you dont want or need it.

I personally have only driven a 90 pov spec TD5, 110 TD5 with TC, pov 110 TD5, 110 tdci off road. All in the same conditions so its not throttle cut.

Most notable and recent was Red Lane in Wales. Did 3 runs in my old D2 rear & middle locked with TC required much more throttle input ad I could feel the TC was over working and causing resistance, requiring more throttle input. You could feel when the TC stops at the end of some areas of the track.

Same run with TC off. Far less throttle needed just let the thing drive, felt much more control and much less throttle.

Went again with nothing locked and just TC made it about 10 meters before totally stuck 🤣

All im saying is the TD5 TC isnt exactly advanced, sometimes its easier without.

In the same way track driving is often easier and more controlled without "driving aids" Instagram @defender_ventures

TC is an incredible tool to have in your toolbox, but it is not fix-all people expect it to be. And especially when you find yourself swivel balls deep in mud or sand. Having the ability to turn it off would be something that I would do too, if I had TC on Miffy. I have often used the off button in the Freelander 2 and it does help, but only to a point. As with the ATB diffs that are so popular TC is only as good as the amount of traction you have. Zero traction - Zero well traction and no amount of TC is going to help Rolling Eyes

I am thinking about doing this on my TD5 although it doesn't get as much off road use as my Puma.

The Stability Control dash switch you describe on the Puma does not turn it off completely, driving on wet roads when you get into a slide it will still kick in, just later than if you don't turn it off.

The main reason I had the switch installed in the Puma was to disable the ABS as it can act strangely and actually stop the brakes from working and let you roll back an alarming amount in a failed hill climb.
For example if you are wheel-spinning near the top of a hill and have to abort the climb and stamp on the brakes to hold your position, the ABS will not let you lock the wheels and will let you roll back down the hill a bit which can be a big problem.

I do think the Puma TC sometimes stops you from accelerating too and spinning the wheels which is why I just turn it off completely and use my diff lockers instead to completely rule that out.

100% agree with both of the above. Sometime you want to spin the tyres aggressively - i.e to clear the treads from clay etc.. Instagram @defender_ventures

Can you actually turn the TC off in a Freelander 2? I know you can turn the Stability control off and have the TR modes. Not done any off roading in one of these before.

Well, after a short delay, I am accumulating bits rahter than spending £140 I am spending less than £30.

Piggy back fuse, relay and a second hand TC switch from eBay.

I'll let you know how I get on.

Oh, and to answer the "why" questions (again, because I already did in my original post Whistle ) - I had an expereince on a green lane , very low traction - sodden grass and the line of the lane was not quite straight up the slope. We decided to winch up the lane to avoid surface damage as turning round was not possible due to obstacles already negotiated that would have been too risky to attempt going down the slope. Anyhow, started winching, initially in neutral all good. Decided I wanted to drive assist and so first low with no throttle should help a bit. Turns out, because of the low traction, one wheel starts to spin and the ABS cut in and effectively locked one wheel permanently. Put her back in neutral and the wheel immediately started to roll again.

So there you have it. You may now return to your debates over the pros and cons, but in my view, like most driver "aids" having an off switch is a great option to have.

Agreed- well worthwhile installing.

We have a switch on ours that we can switch it off.

We use it as a training aid as well as when the TC can be too intrusive on some obstacles, we find particularly so as we are running a larger than standard wheel/tyre combination.

TC is a great tool, and sometimes can be the difference between making an obstacle and not.......but sometimes being too intrusive can also be the difference between making an obstacle, and not!

Most recent example I can think of was driving on a fairly gentle slope with cobbly boulders and shingle up to sort of fist size, TC on, we were struggling, TC off the grip-slip transition was easier to feel and we were able to make better progress.
