Thread: Disco 3/4 Automatic Transmission FAQ - 6 Speed

Just an update on my auto trans since it failed. The auto mech stripped the box and found it fairly heavily damaged. They decided to send it to zf in Sydney for the rebuild. Just got word today that the mechatronic is stuffed and needs replacing. At least another 2 weeks wait as on needs to come from Germany. Can't wait to have my car back as I'm sick of bloody toyota rental cars

Ok - got the genuine ZF metal pan and filter etc to go in and currently have 10 litres of oil - with access to more if needed.

So doing the oil change/pan change at home what is the best way to go.

1. Just drop the pan and change it and refill with the approx 5 litres new oil and then drive for 1000km and then drop the oil in the gearbox sump and refill; or

2. Disconnect the cooler hoses at the oil cooler and with the engine running catch the dirty oil coming out the oil cooler inlet pipe with fresh oil going in the oil cooler outlet pipe back to the transmission.

If 2, do you have do the sump/filter change before or after the oil change? Also does the transmission go into in park or drive or neutral as the oil is being pumped out and new oil pumped in. Does the engine have to be running?

Responses from those who have done it would be appreciated. I appreciate there is a little more to the oil change but the above are bits I am unsure of.

Thanks

A restart sorted it for now, but need to get home first (300km away).quick check of oil level and that's OK. Next issue will be to get it down to perth to have it looked at. Any recommendations for repairers in perth?

I have a 2010 Disco 4 with 150,000Kms on the clock which I bought recently quite cheaply! The transmission was shuddering a great deal so I decided to have a reconditioned box installed. Barbagallo (state agents) put me onto Precision Autos in Osborne park where they send all their auto problems. Took 2 days to remove the old box and fit the new one. They have several boxes already overhauled ready to go on the rack! Cost $6500. (ouch!) When I picked up the car I was able to see the old box which was already dismantled. Torque converter lock-up plates have been slipping and all the bushings in the main housing area were very worn. It has a 12 month guarantee and I have been told to take it back then for a complete oil change and have regular changes after that. Car is good now, changes are smooth and almost un-noticeable. Also the reconditioned box comes with the metal sump.

That a quick turn around for you. I'm still waiting for the trans to get back from Sydney for mine.........

Hi Gary did mine recently , I did a complete dyi flush , I bought a small 12 volt pump of ebay , disconnected the top hose on the oil cooler replaced it with a clear plastic hose , just to see what direction the flow went , then ran a hose to a bucket to catch the old fluid, setup the pump to pump in the new fluid in , oh I drove the car around for awhile to get it up to temp, so then start up the car ran through the gears then left it in drive, oil comes out quick so i put a clamp on to restrict it a bit , while the 12 volt pump pumps in new fluid , I stopped it after the old fluid started to change to clean fluid , I used about 14 ltrs , then reconnected the hose back to the cooler , then with the car in drive remove the plug for filing on the transmission and top up until it comes out , if you don't have it in drive and running oil will pore out, also i put 2 tubes of DR Tranny in it , runs sweet now, cheer Pete
here the pump i used

Thanks Ralasa - great advice - I see that the Brits are using garden pressure sprayers to get the oil so I might investigate that was well - though the electric pump will come in handy for other oil changes.

Cheers

There is a dude on you tube that has dumped the oil from the sump and just refilled it using a funnel and gravity .

Well, I went back for the first check up (1000Ks) and all is well. Changes are very smooth and there is no shuddering of slipping clutches in the torque converter. Ian (Precision Autos) did a comprehensive driving test in the car and he was quite happy with the result. So now, all I have to do is go back in 12 months for a complete oil change as I have been told this should be done on a regular basis.
