Disco 2 Td5 Auto rev range.

[Disco Muppet]

Hi all
Driving my D2 along the highway today.
Normally around 90km/h the rev range is around 1800-2000.
Today, it seemed to be slightly higher.
Any ideas as to what could be causing it?
Checking online, seems to be the ideal rev range is a bit higher than this, around 2500..
Any thoughts?
Cheers

You are a worry-wort.

The td5 auto will sit on about 2200 at 100kmh with the TC locked. If the engine isn't warmed to normal the TC won't lock and the revs will be higher. It could be a whole range of factors, none of which are a problem.

Have a read of the Description and Operation section of Rave covering the Auto.


And have bothered checking your leaks or was that just yesterday's "fret du jour"?

No. I get worried about things and then when i get the potential answers i sit around and do bugger all. :p
First truly my own vehicle. Im 18, and I just forked out rather alot for this car.
Of course i worry about stuff. I just noticed it was running differently.
Doesn't mean im going to have a whinge if i scratch it offroading.
Bought it to go offroading, and the last thing i want is it to conk out in the middle of no where!
Seeing as i drive upwards of 400kms a week as well it kind of is important to me.
Apologies for ranting though, your answer proved very helpful

And yes. Leaks have been checked, doing a more thorough search today.
And forgive my ignorance but what is the TC you refer to? Traction Control?

[biggin]

TC: Torque Converter (in this case)

If you haven't already done so, grab a copy of RAVE. It is a gold mine of information, not just a workshop manual, and the Description and Operation sections will give you a fairly good idea of how various components interact.

The Transmission ECU takes the following inputs from the ECM:

Engine air temperature
Engine Speed
Engine Speed fault flag
Engine Temperature
Engine Torque
Engine Torque Fault Flag
Friction Torque
Maximum Engine Torque
Reduced Engine Torque
Road Speed
Status of engine torque reduction
Throttle Position

Each of these inputs will effect the way the Auto behaves, so if the weather is cooler or hotter than usual that can effect the revs you are seeing at a particular road speed.

I reckon there is a very common neurosis that afflicts all new members - "AULRO faultus nervosa". The symptoms are a tendency to imagine that your D2 is suffering from every potential fault known to the forum. After a while you realise that it's really not that bad. On the other hand it could just be that the small niggles get fixed over time. ;)

I've had my D2 for just on 12 months and I think I'm almost recovering.

Hope you are travelling well,:) It's as OffTrack said, In Canberra the last few cold mornings, mine stays high till it warms up a bit, hope this helps too :angel:

DM, basically like this .... the lockup clutch in the torque converter won't engage until the engine temperature has reached a certain point ... it's driven from a timer, that starts counting down once the set temoerature has been reached .... THEN if your're doing over about 82kmhr the lockup clutch will engage, droping the engine revs and making the driveline solid (no "slip" from the torque converter).

If it hasn't reached the set temperature, and your doing 80-85-90 kmhr, then the torque converter clutch won't have locked up yet, the torque converter will be "slipping" (perfectly normal) and the engine revs will be higher, around 2500-2800rpm ... once locked up, the revs will drop to around 2000 @ 90kmhr.

If your temperature guage needle is below horizontal (from a cold morning start) the lockup clutch will not engage for a while until AFTER the needle has reached horizontal (and sometimes, you can encourage lockup by easing up with the right foot a little once you're up to temperature).

The colder the morning, the longer this will take.

Thanks guys!
Seems to have settled down now without any dramas..
# OffTrack coolant leak did not present itself this morning...
Will investigate some more.
Cheers for the input guys.
BTW - highly unrelated.
SuperCheap and Auto one to be trusted with fittings?
Driving lights, UHFs etc?
Or is it better to give it to an autoelec?

I got some ipf 900xs 18months ago for 350 of eBay and bought my UHF from an online store. Prestige something... Point is look elsewhere as supercheap is often supercheap quality. In regards to UHF get an 80 channel one if you can, just because...

[Fluids]

Yep ... Super CHEAP ... where price is EVERYTHING and quality is nothing :p

Try here for your UHF Prestigecom.net.au Your No1 Australian Destination for Twoway Radio, UHF CB, GPS and Wireless Communiations (http://www.prestigecom.net.au/)

The UHF CB Bundle packs on the LHS ... GME bundles or Icom bundles are good quality ... Uniden is not as good.

The Icom IC-400 or IC-440 would be my choice.

[trevor]

Thanks fluids. That's where I meant. Theyre real good to deal with and quick postage.

[Disco Muppet]

Thanks guys, however i think i may have not made myself clear...
I meant the actual fitting of it, like installation?
But thanks for that link, ill deffo check that place out!

Is uniden still alright though? or is it better to spend that little bit extra?
Cheers

[Fluids]

Personal opinion, and that of my radio nutter BIL .... GME is much better quality than Uniden ... Icom is better than GME ... GME is Aussie.

It's likley to be with you a long time ... and may even migrate with you to your next vehicle ....

The D2 cab / dash space is pretty limited, so my take is to get a set with the radio out of site, and all the business end on the handset ... like the Icom IC-440, or GME equivalent ... I could be wrong but the GME doesn't have a speaker in the handset ... the Icom does.

[trevor]

I've got a unison and happy with it. I didn't install my own spotties because I wasn't game enough to split the headlight wire. I installed my own UHF though, very easy. I've got it installed on the roof plastic thing and ran the wires through the firewall and up the pillar. Definately a DIY job

I think it depends very much on who works at your particular Supacheap and who is on shift that day.

There's nothing like doing it yourself, though, for learning how it all works as goes together, particularly if you are planning on going off track. there's plenty here to give you advice too if want.

And this (http://auto.howstuffworks.com/automatic-transmission.htm) is a pretty good intro to how Auto transmissions work if you're interested

Cheers

Is uniden still alright though?

Dunno.
My UH011 is only 20 years old now, so I will have to give it a while to see if it is reliable.
In performance tests there is only a bees er whisker between different brand performance , so if and when I have to rebuy for 80 channel I will buy another Uniden.
