D3 TDV6 torque converter problem

[PeterOZ]

hoping some of the knowledgable folk can advise on this one.

My D3 has for about 6 months had this "noise" and vibration that comes in at around 50 - 70 kmh and it noticeable as you just back off a little on throttle or slightly apply throttle.

It almost sounds like a "brrttttttttt" sort of noise, and apprears to resonate through the drive train causing a vibration to be felt.

Very apparant when cold.

I have had it to the stealer about 5 times for this and they have no idea, keep telling me they can not hear it and when one of their guys came for a drive one day he did hear it but still they can not dignose it.

They did a transmission service, covered by the lease company thank goodness but no difference. The noise and vibration is gradually getting worse.

I spoke to MR auto at Redcliffe about servicing costs etc for my D3 as I'm about to come off lease and keeping the car. I mentioned the symptoms I am getting and immediately he said it was the torque convertor. they have had several present of late with this exact issue and symptoms.

Anyone else have this expereince? The car is at the stealers at present and have asked to to look again at this and told them what MR had stated.

Not sure if it is a warranty type thing or not. As I have had it to LR now 5 times including extended periods left with them, 3 & 4 days I expect that LR should warrant this problem. The car is covered by LR extended warranty.

Would love to see what people have expereinced with this and what the costs are.

Cheers
Peter

Had exactly the same with my D3 when I first got it. Was taking it in for some warranty work when I felt a vibration, it was like driving over a rumble strip. Got to the garage and they eventually replaced the torque converter. That solved the problem and thankfully it was still under warranty.

Hi Peter,
If you want to talk to someone who has been through this then normthe1 ,on this forum would probably be able to help you out. If I remember correctly his was right at the end of the extended warranty and I think he ended up with a complete gearbox reconditioning, not sure about that but if you were to PM him I'm sure he's be happy to talk to you as he seems like a good guy

thanks mate shall do

Not sure about your description of the noise but the vibration has been a big problem with the Poms on their forum DISCO3.CO.UK They call it the Judders there is quite a lot of posts there to read and the problem they have had has been rectified for all of them by a simple oil additive called Dr trannie shudder fix, or something close to that. May be worth a look if you have to fork out for the converter. They swear by it. But dare I say it they are P... Regards.

I have had similar problems, especially when towing.

Agents told me I require a new TC,
ZF specialist told me the same
Independants told me the same.

Well I did a double flush , with FUCHS 4400 as recommended by a guy on a BMW forum.Did not use the L/Rover spec Shell oil 1375.4

Made it much better still had a slight shudder.

Then on the Ford F150, BMW and Jaguar forum, the guys had exactly the same troubles in their ZF6HP26 boxes as we experience, but they add an additive with excellent results.
I for one don't believe in additives, but what I have read I couldn't believe. After an e mail to LUBEGARD USA I eventually found an agent in South Africa.

Ordered the stuff added it and .................................................. ......
MY GEARBOX AS SMOOTH AS THE DAY I BOUGHT IT AND ZERO SHUDDER.

Have driven 500km now, and it's amazing stuff.

Long term , can't comment yet.

The stuff is
LUBEGARD Highly Friction Modified ATF Supplement

and then I added the magic potion
Dr. Tranny Instant Shudder Fixx


Really this worked for me!!!!

WOW! dunno mine is a shudder per se, more like a vibration and rumble, like a resonance through the drivetrain. Hard to describe.

I had major noise, vibration issue in the diff of my old Toyota surf a few years back and added a "magic" additive as well, made a world of difference.

Just be careful when replacing fluid or adding additives to correct a shudder, either may correct the shudder (for the moment) but it could be masking the real problem. When you change the fluid and filter cut open the filter and check for debris.
Any metal or clutch fibres indicate that there is a problem which a fluid change or additive addition won't fix.

It is common for torque converter clutches to be the cause of these shudders due to them breaking apart. This can be repaired by either replacing the torque converter or cutting it open and replacing the clutch.

I have done that, replaced the sump with a steel sump and a new filter.
The old sump had ZERO filings on the magnets and ZERO filings in the plastic filter.
What this additive do is to remove the glaze that forms on the TC clutches.

I have just returned home last night with this vehicle, really she is so smooth and than all SHUDDER IS GONE.

My concern is , that the OEM oil SHELL 1375.4 cannot cope with our heat and weight we lug around here in Africa, and it cannot last 240 000km or ten years. If you read the specs this oil say nothing about anti shuddering properties while other brands its build in.

Just this weekend I travelled with a friend in his Prado 4.0 V6 and true nuts going uphill he has shuddering too, he denies it's from the gearbox , I told him it's same symptoms I had in my D3 and its from the tranny.


I am so impressed with this product I ordered it again just to have it in stock.
