How to Flush and Replace Your Automatic Gearbox Oil Professionally Using the Wynns Transerve Machine from Britpart

Hello and welcome to the Britpart workshop. My name's Danny Hopkins and I'm here in Shropshire with Paul Myers, who's Britpart's MD. Paul, you don't just sell parts, here, do you? You also offer expertise and guidance, that sort of thing. Absolutely, yes. With the experience we've had in the trade for the last 35 years, and a lot of the staff we have, have worked for us for that sort of period of time. We can offer technical advice as well. And example of that would be the Land Rover survey show at Peterborough. That's right. We had a team there, who were demonstrating diagnostics machines, and also working in a workshop arena with a lot of our guys, fitting new parts and repairing a Discovery One. I remember it well. We were working there, with the Links Diagnostics rules from the Discovery. All the parts we fitted were Britpart, and I have to say, everybody that I met from your team was absolutely brilliant. So, it was very successful. Thank you. So, this is a machine that you also sell to your trade customers. What is it, and what's it for? OK, this is a workshop tool, which may use for like cleaning out the transmission, automatic transmission, on the Land Rover cars. Basically what we do is hook it up to the car. It then monitors itself, and takes out the transmission fluid, replacing it with clean transmission fluid, and flushing it through. Brilliant! And this is an additive that you use with it? This is the additive which helps clean out that processes. The advantage of a machine doing it, it that we can get about 95% of the oil changed in a transmission. OK On a standard drain and change of filter, on a transmission, you're probably only looking at 40% of oil being changed. Goodness me. OK, I didn't realize that. So, this is really worth doing then? Absolutely A higher millage car, or heavy use car, it really cleans out and gives the gear box a deep clean. So how does a retail customer make sure that this is being used on their vehicle? The can specify that when they go in and ask for a car to be serviced. Talk it through with a technician, and ask is it relevant for the mileage of a car. And if it is, they can arrange if for you. Great! And this fits onto any Land Rover with and automatic box. Correct, yes. Great stuff. OK, well Lets go over to the work shop now, and see if Steve and Martin can replace 90 to 95% of the automatic transmission fluid on a Discovery Four. Right, so we've got this Discovery Four here That we're going to be performing a gear box flush on. The first thing we've done, is raise the vehicle up in the air, and take of front most steel under tray and one of the plastic corner pieces. That's allowed us to root the gear box flush machine's pipes onto the oil cooler, which is where its going to retrieve and pump the new oil in. On a Disco Four, the oil cooler is underneath. On a Discovery Three, the oil pipe fittings are accessible from under the bonnet. So, the oil pipes are connected. The next job, is to plug the machine onto the vehicles battery, which will power it up. The machine will start up. It will then ask us to run the engine on the vehicle. Once the engines running, it will start pumping, it will fill this window on the machine with gear box oil. You can then go into the menu and you can select additive load. What that does, is once you've poured the ATF additive in, running the vehicle for five to ten minutes, will pump that additive through the gear box, torque converter, and all the oil pipes, to clean out any debris before we then introduce the new gear box oil. So once all that's in, we can refit the cap, press the button on the machine, and that will pump the additive into the oil system on the car. So that's introduced all the additive into the gear box oil system on the vehicle. The vehicles oil pump in the gear box is now pushing all the additive around the system, which will free up any dirt and debris, which is then going to be dropped out when we replace the oil. While the gear box oil flush is going through the system, its worth while, cycling through all the gears, while keeping the vehicle stationary. So, go from park all the way through to drive, back to park. Doing this a couple of times, just make sure that all the sludge is taken out of all the different valves in the gear box. So now, we can go back into the menu and tell it how much oil we want it to pump through, and how much it will then replace on a one to one basis. It will measure the old oil coming into the machine, and replace that with the correct amount, coming back out into the system. So ten liters. We know there enough fluid in the tank. And we've already added the additive, so we can skip that section. And now, that's started the procedure. Its going to measure the amount of old oil that comes in and systematically pump in the right amount of new oil. The life blood of an automatic gear box is its oil. Now here we have two lots of gear box oil, and these are exactly the same oil. This one, however, has been through some use. This one is fresh. Now, contained within here, there are lots of little bits of dirt a debris that are suspended. Now, it may look OK, but if these little bits of dirt clog up valves, then the gear box is not going to function correctly. Where as, here we have lovely clean oil. That means there's not debris in it. Its not going to stop the gear box from performing its vital functions. Its a simple thing, Change your gear box oil regularly. This could spoil your journey. This is going to get you there. OK, so the machines just coming to the end of its ten minute flush cycle. In a few moments, it'll start pumping the old oil out of the system, and replacing it with new. It'll do that fully, automatically, until all of the oil had been replaced. Also, its clear to see, when it does do that, the oil in this window should become visibly cleaner as the machine goes through the process. What you can see on the display is the amount of oil coming into the machine, the old used oil coming into the machine, and its counting out the new oil that its pumping back into the vehicle. So, all of the old oil has now been dispelled from the pipes, the torque converter, and the gear box itself, and replaced with new oil. We're not going to worry about putting another additive in this now because we know its been flushed fully. So we can go and press that to skip, and the procedure is complete. The next thing we need to do is replace the gear box oil filter, which is going to be the next in our series Britpart Workshop videos.
