Disco 3/4 Automatic Transmission FAQ - 6 Speed

I was up at the Dowerin field day on Wednesday and noticed Alemlube had a stand.Out of interest enquired on the cost of their ATF flushing machine 47070A....show special price $5500.Looking on the Bay there are machines that appear to do the same job for a lot less Gearbox Oil Exchange Changing Cleaner Cleaning Machine Stable Safe Vevor 871248662264 | eBay We have a few vehicles to change the atf on, the only problem is understanding the 'chinglish' translation of its operation.Has anyone experience with these machines from China?

Love the chinglish instructions, i'm not sure what they mean by "butt the roof of the car" :)

I wonder if the upgraded 6HP28 has a greater or lesser failure rate than the original 6HP26?
Pro'ly depends on if the torque converter has been upgraded too, as that seems to be the item that fails first.

The description of our troubles is here: https://www.aulro.com/afvb/wa-report...ml#post2928257

This was at 282K km. When we bought the vehicle we were told it had a 'new' transmission at 160K. We purchased at 217K and it had a full flush at 220K. I intended to do it at 280K but decided I would get it done after we got back from the trip. [bigsad]

After umming and ahhing and undertaking untold research, we decided that we would keep the vehicle and invest in a rebuilt replacement transmission and keep the vehicle long term. Our mechanic provided us with a quote to remove the mechatronic and airfreight it to Dandenong where it was placed into a rebuilt transmission and fully tested. The unit was then freighted to Darwin and installed in our vehicle and the software for the mechatronic updated. Our old transmission is now on its way back to Dandenong. We also had the engine main seal replaced while the transmission was out as that was beginning to leak.

We have only had the vehicle since lunchtime after we arrived back from a week away. Obviously it is much smother all round than it was, although the vehicle still has to think for about 1 - 1.5 seconds from a standing start if you want to accelerate quickly. I had hoped the software update may have fixed that.

The vehicle has to go back to have the transmission checked in 30 days or 1,000 km (whichever is first). The transmission runs out of warranty either in 2 years or 50,000km whichever is first and for us it will most likely be the 2 years.

Can I ask the cost?

My D4 (2011 HSE with 308,000kms and had since new) is feeling very poor. Had the flushed and pan upgrade etc but afraid its 300,000kms has the box failing.

• locking and unlocking on down hill (no braking at all)
• Shift under heavy foot is a big thump and occasional no go for before it finds a gear....
• feels crap...

Anyone had their 6 speed done in Perth?

thanks

I didn't include in the post above that I had not had any shudder at all. In the last 2 or 3 weeks before we left on the trip on 3 July I had noticed a slow change up once or twice when towing a box trailer of palm fronds to the dump - barely a 500kg load.

The cost of the transmission - swap of mine for the rebuilt unit - was $5,500. Being in Darwin the freight (on the account of the re-manufacturer not my mechanic) was $700 total. 6 hours labour for the job including a new rear main seal while it was out.

Not many options for the rebuild here in Darwin (I don't know what you have in Perth) but mine came from a reputable and recommended firm with the 2 year or 50,000km warranty which is some reassurance. It back to the mechanic in a week or two for the mandatory 1 month or 1,000km check under the warranty.

I had mine done at automac
Automac Transmissions | Perth's Trusted Transmission Specialists
They where going to rebuild mine, but once it was apart decided the damage was to great and sent the box to ZF in Sydney as they have the capacity to load test them before installation. They wanted to make sure it was 100% as I was living in the Pilbara at the time and we didn't want any warranty issues.

Might be a bit late, but Auto Trans R Us in Balcatta are my go to (still for anything transmission that DazzaTD5 hasn't time to do).
They rebuilt my 4HP24 in the RRC and fitted Trutracs and an additional ATF cooler for my D2a and some other bits like an HD torque converter, plus always ready to provide advice.
