Disc 3 Shudders Going Up Hill

[barracudaJB]

Hi,

First of all I thought I might say great to be here and I'm excited about finally buying my Disc 3 TDV6 SE - Auto Trans. I love it! Have already started polishing the exterior trim from a sun damaged grey to black.
Got a 3 Month warranty with it and looks like I might have to take it in.
Was hoping I could share what I think might be an issue with the group for some suggestions if that's ok.

The car shudders/vibrates driving up hill.
Driving at 40-50Km/hr on a slope of around 40 degrees the car begins to vibrate until it drops into a lower gear which it then picks up speed and smoothes out and stops vibrating.
I'm guessing it might be a torque convertor or diff issue. Has anyone else had this sort of issue previously or know what it may be?

Cheers,

Barracuda

Sound like the auto... most probably the torque convertor as it loads up. Mine was identical to this on inclines and a service with fluid change etc stopped it.

Be aware though that the longer you wait, the worse it will become.

However the D3 is a pretty full on and an amazing truck and you will mostly enjoy your time with it but make good use of your warranty while you have it. There are a few known issues and it would be good practice to check them all out while you have warranty to back you up.

Welcome to the forum by the way! :)
Cheers.

Yep, The torque convertor.
I have just had my replaced.
Same symptoms exactly.
Go to an auto trans specialist, as a suggestion.
Huge price variance to the usual.

If you have a Auto Trans Shudder, start looking at the TC first.
This was certainly a less expensive option, and the outcome l am very happy with.

Torque converter most likely. With your warranty they will send it to A&B in Melbourne to be fixed. They do a good job.

[Mully]

Hey Dave was that a reco torque convertor for $750??

Cheers.

[barracudaJB]

You guys a brilliant.
Thanks for that. Looks like I'll be sending it back for a new Torque Convertor.
Bought the truck from Trivett so I'm suppose to be getting a replacement Discovery while I wait for my baby to get fixed. That should be a bit of a treat also. Hope it a new Disc 4. Ha ha:D

Keep you boys posted.

Yes it was a reco one.
They provide a good warranty, and keeps the cost down.

[Mully]

JB hope it all goes well for you and you they don't give you a Prado for the loan :).

Dave I had been told by someone who 'should' know that all the reco ones out there are obviously failed ones & no one has really resolved the issue with a rebuild option. This was several months ago however & the issue is now on a large enough scale I'm sure for reco units to have been a priority to get resolved. Don't know why they couldn't reco them successfully at that stage... seemed a little odd I thought.

I've never rebuilt an auto let alone a TC so it's good to hear this has worked well for you. What sort of warranty did you get?

Apologies for the sticky nose, I'm keen to consider all options in the event I have to make that decision at some stage.

Cheers.

Mully,

I don't know yet what they'll be doing. I've just contacted them to make an appointment but I will be probing them to make sure they do a good job. The car is 2nd hand and it came with 3 month warranty.
Any tips for what I should be telling them to do or use in the repair job?

BTW, I'm suppose to be getting a LR as a courtesy car. Cross fingers....:mad:

[Busman]

The warranty l have recieved is 12 months or 20,000k, which ever comes first.
I am very happy with the end result.
Ensure when they do the TC, that the auto trans is serviced also.
Degeneration of the TC would most certainly of fouled the auto trans fluid with metal particals, that block the filter and cause major issues.
Work on this basis, and success is acheivable with this issue.
In my previous post, l have noted the costs to me to date.
Hope it helps:)

[barracudaJB]

Oh well!
I'm back with an update.
Had the car in the shop under warranty getting them to fix the shuddering in the transmission.
I asked them directly to change the Torque Converter and change out the fluid.
They told me that it won't be the TC and so they overhauled the Transfer Box.
Got the car back and hey guess what. It's still shuddering.
It's going back in the shop again.
Grrrrrrrr.

[TerryO]

What a bonus, you got a overhauled transfer box and will now get a overhauled Auto as well. ...You lucky lucky bugger! ;)

cheers,

I guess they didn't take it for a drive then, just assumed they had fixed it.

Doesn't anyone test drive cars anymore:confused:

I certainly hope you are not paying for this transfer case.

The methodology of D3 mechanics seems to be - don't bother diagnosing the issue - just replace parts until the issue is fixed and charge the customer for all this gear that is not actually needed.

Actually, they claim to have driven it before and after the repair.
They claim they couldn't replicate the problem after the repair. Took me a day and it started shuddering.
It actually is a little better than before but it seems to be getting worse with every day that I drive up my 40 degree hill.

No I didn't pay for it because it's still under warranty.
So I sure as hell hope they fix it before the warranty runs out. I'll be knocking on their door even if they don't.

[Busman]

I am amazed that they overhauled the Transfer.
Bottom line, when the auto starts suddering, the TC has degenerated in most instances and starts heating up.
It will affect in some instances under load the rev range of the engine, as it putting pressure on the TC.
Talking from experience, our local dealership said it was not the TC, and advised to overhaul or replace auto trans.
Yeah, $7,500 + , l need a second opinion.
I went to a local auto trans specialist, and he drove the car as said, yes it is a TC straight up.
Was fixed quickly and for significantly less money.
Absolutely no further issues to report, and very smooth power etc.

One last bit of advise: Ensure when the TC is repaired,ensure that the auto trans pan/filter and fluid is changed.
Otherwise the metal material from the old TC will foul the filter, and will cause damage in time to the auto trans.

Transfer box?? Wot tha?? Reckon you can trust them to fix the real problem?

Makes you shake your head and wonder.... I had stand up discussions with the 'head' mechanic in one of Adelaide's larger Land Rover yards and he too refused to accept this shudder was the auto... they even had the truck for a day and came up with "might be the ballasts.." and now they have closed down. Wonder why... :eek:

Still blows me away how those supposed to know, mostly don't.

Hope it gets sorted for you quick fella.

Cheers.

[barracudaJB]

The D3 is going in on Monday and hope to hell they get it right this time.
Busman,
When you were having the shuddering problem, was it shuddering in each gear or only in 1 gear at a certain rpm and certain speed?

Cheers,
