Does cutting the wire effect TCS around town?

Danny, what you have heard is bollocks. If the system is working as designed, it will not over-heat brakes and cause drag. There are a lot of misconceptions about the operation of TC out there.

I traversed the Simpson with a host of different model vehicles (with and without TC) and none of them exhibited any issues.

Hi Dan. Can you take some photos of the kit in place to see what it looks like 9both underneath and in the cabin (ie lever/ button). You mentioned this was still factory looking - I'm a fan of this, but I can't understand how the manual kit can still look factory in the cabin (with the electric kit, you can obviously use the spare buttons on the dash).

Cheers!

It took me all of 2 hours to fit, and I can disengage it then turn off the car. Restart car and re-engage without TCS getting upset.

Mate paid a bit more for the electric set up and the one time he needed it it failed.

And the car looks factory due to it having factory parts (although later) No holes had to be drilled......only rivets removed and replaced

Hi Ballas, mine is a factory DIIa but basicly the same as the TRS kit, the high/low lever in front of the gearlever looks the same.

The kit below is from Ashcrofts Transmissions in the UK

It basicly replaces your high/low range lever with the D2a style lever allowing you to lock your centre diff.

All that cutting the wire does is stop the car disabling the TC "if" you engage the Difflock then start the car. it does not affect its normal operation at all.

Why anyone would want a CDL but no TC is beyond me, adding a CDL and having TC as well, is as close as you'll get to having front and rear locking differentials, but without the install cost of those + when you do have a CDL the TC works a LOT less anyway. The more "physical" locks you add, the more redundant the TC becomes.

Regarding the TC in sand. Generally its not too bad. On the flat, ok, but as said in soft sand and up hill, it can kill your forward momentum. Last trip to calcup hill, we had the chance to observe a stock td5 and stock v8 d2 in these conditions. In the TD5 there was an inherent advantage in that booting it up hills, the was not the power to cause wheel spin as much as in the v8 so TC did not kick in as early but it did kick in causing loss of momentum. In the V8 it just murdered it going up a hill. Planting the foot to get a run simply caused mass TC action and by the time we were half way up the slope, dead and buried. The TD5 also had a manual activation of the CDL available and with this on, and TC off, one attempt at 150 meter upslope runs, done easy.

TC will not always cause problems but I saw enough to say that in soft big sand, especially uphill, and with the power of the v8 to temper, TC can be an absolute show stopper.

Err sort of forgot my point there.

Upshot, - CDL plus the option to run with or with out TC is the optimum. Cutting the wire is not the answer as you lose the option of turning it off. I beleive Slunnie has already stated it clearly, a switch to control TC with CDL activated is essential. I would fully support this conclusion.

Do the D2 and D2a electronic ZF's have identical CDL/HL lever mounts (even though it may not have been not used) as the D1 hydraulic ZF CDL/HL lever mount?

I don't have a D2 but I would assume that if you could fit the D1 CDL actuator assembly to the D2 then even if it did transmit noise it wouldn't be any different to what you get in the D1?
I suppose you might hear the noise more though if you go from no CDL noise to some CDL noise. Especially since the D2 is quieter than the D1 inside the cabin.

Yes, but the mounting plate will need to be widened where the new lever goes through so it can move sideways, but the mount is the same, also the D2a cable CDL is the same whether you have a manual or auto.

You may want to make yours a bit tidier:(

The D1 linkage system won't fit in the transmission tunnel of the D2 AUTO only the manual just, with some modification.

So if you have a D2 AUTO then the D2a cable system is the only option.

I know the vibration/noise would annoy me. Both my previous D1's gradually got noisier as they aged, due to wear in both the drive-train and the actual CDL selector.

I remember having other cars having drive-train vibration/noise being transferred into the cabin….
