Disco 2 Autobox - Torque Converter or Flex Plate failing?

Postby disco » 11 Oct 2012 16:26

Hi all,

For some time now I have been expecting that my Torque Converter or Flex Plate is on its way out. (2001 Disco 2 GS Auto 230K km's) I know precious little about the actual workings thereof, so here's what happens:

When I tow my fairly light caravan, it generally feels like I am driving a Manual with a slipping clutch. At speeds between say 60-80, when the revs goes above 2600-ish, the accelerator turns into a volume control. More noise, higher revs, but almost no acceleration. This becomes even more apparent on up-hills. When the box eventually locks up, (around 85km) and I have direct drive, it goes like a rocket.

Kick-down is also useless, especially if it jumps a gear. It simply shoots the revs through the roof, with zero extra power.

I did change the transmission fluid, filters, and seals a year or so back, and the levels are currently fine.

I heard that this can me symptomatic of a failing TC. Also, I read somewhere that the flex plate is fairly flimsy, and that some people have done some kind of mods on it.

Does anyone have some info or suggestions on this for me?

Cheers,
Nic

You probably need some specialist advice here, Centurion Gearbox or the Gearbox Company in Midrand. I wouldn't take this to a general workshop, my 5c.

Keep us posted.

Thanks for the info Joseph!!!

(sorry for not replying earlier)

I contacted a few guys on UK forums, and got the low down on the Ashcroft Heavy Duty TC and Flex plate, and I am convinced that this is the way to go!! Especially when towing! One said, that should he buy another D2 Auto, he would do the conversion within the first week!

In short they modify the V8 TC for use in the Td5 which then significantly lowers the stall speed, and slippage.

I also contacted Ashcroft, and they have had no previous orders from RSA. The only challenge here is the price of shipping the things here. (160 pounds!). Also, they add a 200 pound refundable deposit, if you send back your old TC, at the cost of another 160 pounds, which is hardly worth it! So if you do not do that, it will cost you a lot!

I recon though a bulk deal would be best here. (pay shipping once for the order of a whole bunch, and then once for the return of the old TC's). I will investigate, and update this post.

If anyone is interested in joining me for a bulk deal, please reply or send be a PM.

Cheers,
Nic

Contact Peter Street on 083 453 5374. He has some special muti from Germany that he adds to the ATF that could solve your problem. This is a lot cheaper and worth a try.

Hi all,

UPDATE!

In the end I settled to recondition my TC. I had the work done by Centurion Gearbox and Diff Centre. (they send the TC's away to have it rebuilt, presumably by all-o-matic in jhb)

My informed opinion was that the HD -TC would have a negative influence on my turbo lag, and that it does not make sense upgrading to the HD model if I do not also upgrade the turbo and intercooler, which I cannot afford at the moment. (which would still be first prize if I had another 20 bar or so swambo did not know about!)

I still reckon the current TC is too small, and stall speed is to high, but at least now I get lockup, as it should! what a difference!

I am going to Welkom tomorrow, and will report back on fuel consumption, which should be significantly better now too.

total cost: R5871

I will also ad Dr Tranny's Instant Shudder fix (already ordered) but did not want to use this without fixing the actual problem. (IMHO additives can be good, but should not be used to obscure a mechanical problem, or delay inevitable complications, which can be more costly.)

Cheers,
Nic

Well, Good thing they didn't do the work themselves then...
I took my car to Centurion Gearbox and diff on the 12th / 13th August 2014. The vehicle has some thudder sounds coming from it while driving. I was told it was the diff bushes by another person.
The MD, Deon and I discussed that they are quite busy and would only be able to look at the vehicle on the 19th August 2014. I agreed to this and agreed to leave the vehicle there.

As time went by (and I have attached an e-mail for reference), they did not work on my car. Further this, they only told me months later (end November) that they already fixed the bushes, and only told me then that it would cost me R6500.

2 days later, they phoned me and told me there was a problem on my diff too and that would be another R22,000.00. This I agreed to. They “fixed” my car and I drove it on holiday from 12th December 2014 to the 27th December 2014. I picked up issues during my trip and spoke to Nantus about it.

I returned the car to them on the 29th December 2014. It has been there ever since. They keep promising me that it would be done and they aren’t doing anything about it.
I have lost money because of this.

Eventually, after a massive fight, they gave me a Ford Bantam bakkie to drive around in for the weekend of the 13th to 16th February 2015, with the condition of giving me a proper car to use from Monday 16 February 2015 as the problem is transporting my children to and from school, home etc as this is a safety risk. When I went to return their bakkie and collect the car, the MD “changed his mind”. I was so upset because of his blatant ignorance towards the law and safety of my children and poor service that I threatened legal action. His only response was “Go ahead and do it.” I’m not a man of my word anyway and your car will be ready before 19th February.
Guess what…? My car isn’t ready. This has cost me and my business a lot in terms of driving up and down, phoning them all the time (from December to now, I’ve made over 20 calls to them, they have not called me once). This is unacceptable.

I even suggested that they could rent me a car until they have my issues resolved which they weren’t willing to do. They have been rude, unprofessional and not forthcoming at all.

Today is the 3rd July 2015 - Almost a year later. My car STILL isn't fixed. Tried Mediation, they failed to respond. Tried the Motor Industry Ombudsman - They just ignored them.

Now, I'm taking it to the National Consumer Tribunal and to High Court if need be.

Be WARNED!!!!
