Lock up mate

[Muzza]

I averaged 13.6L/100klm with LU Mate on all the way. Got to be happy with that !

On the flat road I could easily tow in 5th with the TC locked and just jumped back to 4th for the steeper inclines. Was generally doing about 92-94kph GPS speed

Extremely happy with that result.

can you tell me, when it drops from 5 back to 4 when towing either manual shifting or auto mode, is it smooth to shift or harsh shift, Ie bang or knock
Thanks

Hi Muzza,
No, you never get a bang or knock. The gear shifts are smooth. Not as smooth as with the torque converter, but nothing like a knock.

As MandM said, it's not a harsh change. You can feel it more because it stays locked but no banging.

I just towed (for the 1st time in the NW Pajero) our small (approx. 900kg) van a few hours (South of Perth)

I don't have a lockup mate or anything similar at present.
What I did note was this:

TC quite often decided to stay unlocked on flat ground at about 105 indicated (about 95 - 97 actual)

Backing off the throttle slightly caused it to lock (revs dropped from about 2200 or so down to 2000 or so) but it very easily and often unlocked again with the slightest load change or throttle shift

When unlocked, AT temps sat in the high 90's or low 100's. (highest I saw was around 109)
When locked instantly started to drop to high 80's


My observations are thus:
No, the TC does NOT always lockup at above 100 as I have read elsewhere.
Manual shifting back to 4th and then to 5th sometimes helped it lock but soon after it unlocked again.

A question: is the TC supposed to lockup in manual mode or does it only depend on speed, throttle, engine load etc?

With a lockup-mate, is a setting of 60 the same as factory or will it still lockup 'earlier' than not having the kit at all?
i.e. on a scale of factory and 'lockup most of the time' what setting between 60 and 160 would factory lockup settings be?

Factory program uses a combination of speed and accelerator pedal position, and gear. At 100kph, in 4th it will remain locked up for longer (ie with more engine load). Manual (Sport) and DRIVE use the same lockup program.

No, not quite that simple to answer. The 60-160 is to allow you to adjust, a bit, the engine load before it unlocks. Most people don’t change it from default. I haven’t tried to determine how to replicate factory.
Lockup-mate will lock the TCC much more frequently. You can even set it to ignore the pedal position and give full control to the driver.

Ordered a Lock Up Mate last night. Putting it into an NX. Can anyone tell me what needs to be pulled apart for install? Centre console removal? Dash components after steering wheel? Not worried about those, had those off before, I’m mostly worried about what needs to come out to get the LED button on the A pillar but plenty of ppl have done it DIY so surely can’t be too difficult?

Not much involved in panel removal. It's mainly getting at he ECU in the passenger foot well and feeding wires to the drivers side over the transmission tunnel, around the fuse box area and clipping the button to the door trim. It's not hard and the instructions Marshall supplies are very comprehensive. The scary bit is making sure you cut the right wires but just follow the instructions and you'll be fine.

Great, thanks Ian! Looking forward to it.

I'd suggest you get a small set of trim removal tools if you don't already have some. Makes it easier and they come in handy for other jobs.

Thanks mate I have 4 or 5 of those plastic tools. Definitely very useful!

Installed Lock Up Mate today. Took a fair few hours haha. But I learnt lots. Ran the diagnostics and passed with flying colours.

Question about something on which the operating instructions aren’t real clear. When can I expect to see the blue LED illuminate? I only gave it a short run but should I have seen it already apart from it flashing either short or long to confirm that it’s switched off or on? Coz that’s all I’ve seen of it so far. Doesn’t stay on? Cheers.

The light (and torque converter) only will go on once the transmission oil has reached operating temp. I think it's about 50 degrees. So you need to drive for a bit to get it warm.

Thanks mate. Taking a longer drive tomorrow so will look out for it.

Mine comes on a lot earlier than waiting for the temp to reach 50 degrees. More like 30 so it doesn't take much of a drive to get it to start up. I haven't had a look in the booklet but there may be a setting to change the temp it activates at ?

When the blue light is on, the TC is locked. No blue light (under 30kph for example) it's not locked. So if you are just in normal drive mode, not sports mode, the blue light should be on most of the time and your dash display should also tell you what gear it's in..
