NEW TO AUTO'S. DOWNSHIFTING FROM LOCK ???

[gofer]

hi folks .
rebuilt td5 with auto. 1999.
as above, i'm new to auto boxes.
so, cruising along at 90k's.
box locked in.
2100 rpm approx. start to climb a hill. temp starting to rise as locked box tries to maintain speed.
what is the correct sequence to change from locked to 3rd gear ???
thanks in advance.
gofer :-)
box has only 40k's on it, so i don't want to kill it just yet :-)

Let the box look after itself. If temps are rising enough for concern, lift the right foot.

[PhilipA]

I would say, quick pedal to floor and it will kick down, then ease off to the speed and temperature you are happy with.

OR manually shift to 3 on the tbar, and it will change to unlock 3 then to lock 3 in about 1-2 seconds..

What exactly do you mean? It won't kickdown or you have just it in 4?
It's a transmission just flick it down no need to stop accelerating.
I have the v8 and it will kickdown from 90 if I want it to. Up at 100 it won't though I have to flick it down.
I have had it screaming it's tits off up hill in 3rd for periods of time and have never seen the gauge rise above half even with 2t worth of trailer and leaky trans. (Hope my gauge isn't faulty)
I'm pretty sure the diesels run warmer than the petrol but I've never owned one someone else will confirm.
Going up hill speed is gone in the v8 in 4th I just wear it and go slow.
Check your coolant and like v8lan said lift your right foot if it's a concern.

Hope you work something out that would do my nuts in warming up so easily.

Cheers!

"temp starting to rise" what temp are you talking about? If it's the standard gauge you have a problem. Change as Phillip A says preferably pull back on the 'T' Bar before you start going up the hill so that you are in third lockup when you do climb.

As you are towing, are you running in Sport mode ??

[Lemo]

If you can provide a little more info as requested by others we’ll be able to offer better advice?

Rebuilt TD5? Is this complete engine overhaul?
Remapped? Standard turbo?
Auto? Was it just a standard reco? Or upgraded TC?

FYI
The standard disco temp gauge will sit half way until it’s too late!! not 100% on the exact temp it will go into over temp?

Do you have a secondary temp gauge? What’s the actual temp readings?

Cheers Lemo

i was under the impression that the box " locked up " only in drive position.
box locks in drive when speed is around 85kph, then the revs drop back to around 2000rpm.
regards temp:- using nanocom it sits around 88-90c when on the flat doing around 90k's.
the area where i live is around daylesford in vic. flat stretches with loads of steep hills.
at present i just lift the pedal off, shift lever into 3rd. box changes . i then push the pedal gradually.
thanks for the input. :-)
i'd rather get the answer here, than try when towing a trailer up a hill.

[Lemo]

Those temps are normal, what are you getting when climbing?

There’s a few post on the forum about auto operation etc
If you’re on the web based forum use the search function at the bottom it’ll produce loads of info!

RAVE will also give the complete operation of the box as well[emoji106]

The TC also locks up in third and second, either in drive or when selecting manually, depending on throttle position and load. I think it locks up in first too in low range.

Temps will climb while climbing, you're increasing load, so the engine is working harder and generating more heat. Temps won't stay steady, and FWIW the t/stat isn't fully open until approximately 14* past the point it starts to open.

TC locked, Gary.

[Pedro_The_Swift]

Anything over a hundred and you need to be 100 percent sure of your cooiling system, and the TD5 has lots of hoses to check.
Running the Torque Converter ( TC ) unlocked will heat the transmission oil. Yes you can cook the trans this way.
You need to physically (get under and twist!) check the flex to solid transmission cooler lines... dont lie underneath the connection,,, just in case--[wink11]

[101RRS]

TC locked, Gary.

Oh Ok - is there a way of knowing it is locked? Other than knowing the theoretical speeds that my RRS locks at - from the driving position you would never know.

On the D2 you can see the revs drop and stay stable when locked, ie. it drives like a manual when looking at the tacho, the revs don't flare or drop away with small throttle inputs.

[PhilipA]

Third locks at 70Kmh on light throttle and about that on heavy. It will stay locked down to 50Kmh.
4th locks at 80Kmh and stays locked down to 70Kmh.
You can drive locked for most of the time if you remember that.
The way to tell if locked is when you increase acceleration the revs do not flare.
I drive around the city in 3rd locked in 70zones. I understand that the manual says to drive in 3rd if driving slowly for extended periods.
I don't think it locks in low ratio but will stay in a set gear if the M/S button is pressed.

Mine got to 96 degree`s at 4200 kg all up towing up the hills on the way to Cooma[bighmmm]
I had my Nanacom alarm set at 95 :censored: it is now set at 100 degree`s[thumbsupbig]

[Pedro_The_Swift]

Thats nice Chris,, the V8's RUN at 96 and go up from there---
or at least the silly ones still do[wink11]

can someone tell me the thermostat temp of a standard td5? I have no idea.

[AK83]

....

can someone tell me the thermostat temp of a standard td5? I have no idea.

I've seen the part No listed as PEM100990 for the Td5, and it's rated at 87°C.
I can't remember the exact part No. I have for my D2 V8, but looking inside the housing it's stamped 78°C.
Same thermostat tho, that is you can use a Td5 one on a V8, TD5 thermostat is just oriented a little differently than the V8 .. I think(from memory) it lays flat/sideways whereas on the V8 it's positioned vertically.

[PhilipA]

My 2002 TD5 has an 82C thermostat and usually runs between 82 and about 86 with 90+ on long uphill towing. only once touched 100C on NSW Alpine way 21Km climb. That is 82C first cracking and probably 88 fully open. BTW the fan cuts in at approx. 94C AFAIR.

My limiting factor towing is EGT which can exceed 700 C even with engine temp of <90C. So really the key thing to watch is EGT not engine temp so much.

I have to be careful with cruise control especially when towing. As soon as you lose even a little speed , it will just accelerate flat out and EGT skyrocket.

well thats a D2 trait then,, the V8 cruise is very agressive also,,
I've always thought I could do a better job anyway than CC,,
or maybe I'm just too lazy to adjust the ( prehistoric ) cables correctly [bigwhistle]

[onebob]

...........BTW the fan cuts in at approx.......

Regards Philip A

I think i recall i read in RAVE sometime back that the fan cut in temp was 105degC.

[rick130]

I've seen 100° coolant temp a few times, had to bump the Nanocom alarm up a little from the 'factory' setting.

Interestingly coolant temps are more stable and head temps consistently lower after ditching the EGR system.

Mine seems to be +/- 6kph, it's very aggressive and not economy friendly.

[PhilipA]

That is the electric fan.
The viscous fan cuts in much lower and you can hear and feel it when it does.
