Disco 3/4 Automatic Transmission FAQ - 6 Speed

Hi all,

My 2005 D3 is up for gearbox reconditioning - is there any recommendations in the Newcastle, Lower Hunter area of NSW?

I've been given a recommendation in Wyong, but time is against me.

Hope someone can help

cheers

ZF in Sydney is probably the best place to reco the box at a good price (was $4400 incl GST a couple of mths ago). I think they said a week turn around. You just need someone to remove and refit the box.

Any suggestions around the Albury/Wodonga area or surrounding area of someone you recommend to have do this Trans svc for me. I have just purchased a D3 and have noticed the shudder a couple of times under low revs and slight load. Very worried about my latest purchase being a costly one!

For service I'd recommend Cohuna Automatics:
auto transmissions Cohuna
For a rebuild I'd either use them or ZF in Sydney, the Melb ZF agent is more expensive.

OK I'm thinking the transmission in our D3 is on its last legs - the dreaded F fault when towing along with codes pointing to a worn E clutch.
As a stop gap, and given we don't have much to lose, I'm considering a couple of tubes of Dr Tranny. The trans had a new pan only about 5k ago, so I don't need to change that. My question is what's the best way to get the treatment into the trans? Any help much appreciated.
Cheers

Are you getting slipping?
Dr Tranny won't fix everything but it is good for clutch converter slippage.

DISCO3.CO.UK - View topic - Howto: Dr Tranny

Yes the codes indicate a slipping clutch (incorrect gear ratio). According to the research I've done it relates to the E clutch, which looks after gears 4-6. When the trans faults I lose everything above 3rd :( .

So it looks like Dr Tranny it is, in through the trans cooler. Can someone confirm the hose I'm looking for is the one on the passenger side a few inches down the radiator? D3, 2.7l. Thanks heaps!

Hi Matt

2005 TDV6 auto @255K, BMW steel pan with drain plug.

Similar story to yours, only my new pan fitted about 15K ago.
Was changing from 6th to 5th under heavy acceleration while overtaking, chime and gearbox fault message on screen, stop, restart, al normal.
I have done X3 flushes up to today in 15 K Km - expensive.

Same as you, though Dr Tranny, why not try?
Decided to drain 4ltres, then instill Dr Tranny X2 to oil fill hole.
Glad I changed the oil, although it looks ok while draining, it looks dark when viewed in the receiving container, not burnt or smelly, but glad I topped up with 4ltres of new oil. (LG 6)

20KM test run: no problems so far, but early days, too soon to say if it worked, I would be happy with a "stay of execution" to get a few more years out of the box.

Good luck whichever way you choose, keep us informed please.

Where/who is the Melbourne ZF agent? I couldn't find them.
Local auto service guy mentioned $3500 for a reco. Is that in the ball park?
