Diff lock is only in the Transfer Box so if you were cross axled it would make no difference if engaged, yes TC should have kicked in if fitted.
A bit of gentle left foot braking sometimes helps to get things moving again  130's have feeling's as well you know  |

If tc cuts in you should get a light on dash

TC should kick in but it's very 'reactive' rather than proactive.
It works best with diff locked and with steady throttle, 1500-1800 ish I'd say. You should see the light come on the dash when it activates. Honestly I think I would've been able to crawl over that obstacle in mine, but it takes some getting used to etc. Defenders don't drive themselves like a D4 or range rover Cheers, David Land Rovers of all shapes S3 onwards… Daily is a 110 V8. |

One of the unfortunate characteristics of the Defender's fairly rudimental TC system is that the sensors aren't that good at detecting the 'unloaded' wheel, hence the requirement for more revs as suggested above. The problem with this approach is that it generally goes against good practice in respect of off road driving techniques, which is basically to keep revs as low as possible. This is particularly prudent in this type of cross-axle situation, where traction could suddenly be found. If that is combined with a wide open throttle, the stresses put upon the driveline can be significant. Far better for traction to be found with a gentle throttle, which will also help with making smooth progress. As a result, it is probably better to utilise Andrew's suggestion above of applying some gentle left foot braking. After all, that is all the TC system is doing, the only difference being that the TC system is braking an individual wheel (the one that has been detected as spinning), whereas applying left foot braking will brake all four wheels, regardless of which is spinning. It is often enough to re-balance the power to the wheels that do have traction.
Certainly, it is not a great idea to just give it a bootful when traction is lost in the hope that the TC will kick in. You will definitely know if the TC is functioning (even if the dash light has failed) as you can feel it and you can also hear an audible clicking in the cab. 2005 Td5 | 90 Station Wagon | Tonga Green |
