Thread: Strange goings on with auto

Yeah I know they are not an off tar tire pattern, But as some1 that likes to call an"earth removal tool" a D7 I just find it silly they stamp A/T and M&S on them!! If they put HT or suchlike would be fine.
Ahh well as soon as I get a minute some Pirelli ATR's are going on. bit more gravel orientated .Still not a mud tire by any stretch of the imaginings but nice and quiet as road running is the D2's prime directive.

Have ruled the auto switch out as the culprit

Hi all, Had forgot about my auto problems until a few days ago when some problems returned! To start I will say I have stripped all the covering from the harness that goes over the transfer case and there is no bare wiring.
the symptoms now are hesitation to move off when D or R is selected, Almost as if I have it in N instead. It also would not change up from 3rd until I manually selected 3 then D again, This was at 90+kmh. It also dropped out of lockup at 90kmh+.
Have rechecked wiring connections, connected the Nanacom, No faults, So has me puzzled with its behavior. Am a little concerned it may drop out totally and not reengage! Any ideas welcome!

Cheers Scott

Just re-read this and so...

A few years ago I blew both head gaskets and so also went the liners (V8 obviously) but following that I had a similar situation where under load (hills rather than hard acceleration) it would shift 1/2/3 then on trying 4 it'd grab a fist full of revs, slow right down and start off at 1 again. Repeat until at top of hill, no a good experience in peak hour traffic doing 10km/h up hill. Even in Sydney it travels a bit quicker.

Symptoms were straight out must be an auto issue, didn't so it before I pulled it apart etc. So off to auto specialists, who drove it and all said clutches/T/C clutch/valve body etc. So out it came and $3000- later back in it went. Test drive down road to nearest hill and guess what.

So I buy a $200- diag tool and drive around creating a danger to other road users but it did allow me to watch the engine functions.

Turns out that under load the MAF was shutting down, so ECU sees no air entering engine so says "stop fuel" then O2 sensors are saying but here's all this unburnt O2 coming through "add fuel and ignition". So everything was stuck in a perpetual fight and while this happened the auto just said "I'm outa here" and went into limp mode.

$200- for new MAF and problem solved. But I do have a new driveline.

I know the TD5 will be slightly different but it took almost another 6 months to locate that so it might be worth trying a known MAF or some other sensors swapped in (one at a time) to see what happens. Mine was also in the 80k+ range (until it stopped and started again) and wouldn't happen on the flat with foot to the floor (and that goes to 5000rpm in each gear now).

The harness repair in the service records could be an injector harness. You diesel boys like to change them like underwear I understand.

You are pretty much on the money there with those symptoms and yes I have noticed it acting a bit differently up hills, more so if I give it some right plimsoll! I allso noticed, after I posted this , Freedriver's post regarding his and it could also be low oil from that description, Had not thought of it as there is no leaks at all. yes it IS a L/Rover! the auto was serviced 12000k ago at MR Auto. The service record was for the injector harness
So..... spare MAF's up this way compete savagely with the hens and rocking horse's for limelight. Looks like I will have to get a newie and try, unless I can find the thread on testing it.
Helluva roundabout way for you to get driveline renewed though

Seems like the D2s in the North and South Burnett have caught some auto transmission disease....

I've had an intermittent issue with my auto that, although different to yours, is equally perplexing. And with the $$$ involved in mucking about with transmissions I'm not too keen to play a game of "can you pull thie transmission out and tell me what might be wrong with it please?".

Mine has am occasional rough upshift from 2nd to 3rd. It'll do everything else I ever ask of it without issue but sometimes it'll shift into 3rd with an almighty bang!

It's as if it tries to hang onto 2nd for a couple of hundred RPM more than it needs and then doesn't back off to make the shift. Someone suggested it may be a shift solenoid that is on the blink. I probably should budget for the inevitable.

Anyway, I didn't post this to hijack your thread Scott.

I saw you may be chasing a MAF.

I am too as it happens. I just got a quote from TRS as below:

I can supply a new vdo type sensor cost will be $160.00 inc gst freight via express post is $16.00

I know how hard it can be to source parts when you're out of town.

I hope you get it sorted soon.

Post #2 references another thing to check.

And this one too:

That's my good deed for the week sorted!

Best of luck Scott.

must be all this water over the last few weeks!!! That is a pretty good price for a MAF I think. Will probably get 1 , even if that is not the cause a spare of something that can shut the noise down inconveniently a long way from a workshop is good planning
Thanks for the research
Cheers Scott

Scott,

If looking for a cheap MAF, try:
F00C2G2027 | eBay
plug and play.
I also did the O2 sensors at the same time (AU Falcon - $42 ea for Bosch parts) and it hasn't run better for a long while. Also had M&S + limp home on a recent trip with no faults found by the auto experts.
