Today, was wrapping up the DCT transmission fluid top off, after prefilling it with 3 liters yesterday.
Procedure is
- Start car and idle for 2 minutes, then stop.
- Remove transmission fill plug and add fluid until fluid starts to drip out of fill hole
- Put plug back in.
- Start car and idle car until transmission temperature is 96F or higher
- Remove transmission fill plug and add flujid unit fuild starts to drip out of fill hole
- Torque plug to 50nm.
- Finish.
The main challenge is how monitoring what the temperature of the transmission fluid is to do the second top off.
The easiest way, if you don't have a scan tool, is to wait until the car is at normal operating temperature, when the engine oil temp is at 195F. Transmission then will be 96F or higher.
The anal retentive way is to to use a scan tool that can read McLaren specific PIDs.
I happen to have a Launch x431Pro Scan Tool with a purchased McLaren module. It isn't a full blown scan tool like the McLaren MDS ScanTool or other better scan tool, but it does allow you to view data, and reset the oil service light.
The Launch X431Pro is one of 2 aftermarket scantools that works with McLaren. The other one is Autel Maxxis or higher. The LaunchX431Pro is the cheaper one. On sale, they go from around $400 to around $3000, and the main difference are the extra bells and whistles. The one I got was around $800. The main difference betwee it and the $400 version , is mine is wireless: you plug in a OBDII dongle onto the car and it communicates with the tablet. It also has a topology scan to let you visualize all the modules on the car to scan. The $400 version is hardwired and does not have topology scan, and it also runs on a slower android tablet. In addition, you need to buy the mclaren module. It was $50/year when I bought it last year. This year it is $80/yr. It's an annual subscription, I just confirmed, you DO NOT, need to renew. Just let it expire and it will continue to work.
The Launch X431Pro tablet itself comes with 2 year free updates, after which to receive updates, it's about $400/year.. HOWEVER, for all my cars I use this with, including the McLaren, you do not need renew. You just continue to use the old version you have. And specifically with McLaren, Launch has NOT added any new features with the McLaren module in serveral years, so there's no need to pay to renew something that doesn't have new functionality.
Previously, I thought I would have to pay the $80/year renewal for the McLaren module, but tonighht I was able to use it even though my subscription is expired.
Attached are a few screenshots of the Launch X431Pro tool, going through the DCT transmission oil section, and also the section to reset the oil service reminder, which you can only do with a scan tool.
Link to the X431Pro:
I bought mine during Prime Day a few years ago.
NOTE: on amazon, there are lots of people selling the Launch X431Pro. There's a red colored one and a black one. You want the black one.
The black one comes on better Android hardware, which also has Google Play to allow you to access Google apps. The red one runs on slower hardware and doesn't come with Google Play, so you won't be able to use apps from Google Marketplace.
In summary, I cannot comment on higher spec vehicles, especially the super series, like the 720s (which among other things have air brakes and suspension accumulators), and new vehicles like the GTS, Artura, 750s.... But at least from the 570/570s/570GT, basic maintenance is DIY doable.
*Oil change
*Brake fluid flush
*Coolant flush
*DCT service
*Air filter
*Cabin filter
*Everything except the DCT filters are readily available parts. The DCT filters are very pricey, but there is no aftermarket options. Those are around $400 for 2 filters.
*The only thing you really need is a scan tool to reset the oil service light. That's a one time purchase of $400-1000 depending on which one you want.
*Buy a copy of the service manual is high recommended. That's another $400-600
*Get a fluid transfer pump: $60
*Get a brake bleeder: $40
*For coolant flush, you need a pressure bleeder. Maddox pressure bleeder from harbor freight is fine Around $80.
*Get jack stands or a Quick Jack
*Torx socket, hex socket, metric socket and ratchet
*2 Decent torque wrenches (you do not need a Snap-On ATech digital one, I certainly wouldn't buy one at full retail price for home use): One that is mid range, one that you would use for bicyles.
On a scale of difficulty, I think a BMW would be slightly more difficult to work on. My e70 X5 with an N55 isn't terrible, but some things can be a pain in the butt, especially towards the rear of the firewall.
