If it does not have a torque converter*, and we know that torque converters without drain plugs (like almost all of them these days) hold a lot of fluid, then I wonder what % of fluid gets changed with a pan drop? Now it might be that the wet clutch pack is contained in an envelope that is just like a TC... And it too might retain fluid. For that matter, said unit may not be disassembleable... or easy-draining.Definitely change the fluid, highly recommend dropping the pan and replacing the filter!
I plan to drain and refill the transmission every 10-20k miles, while changing oil, knowing it only replaces a portion of the liquid, where the goal is to replace all fluid every 50k miles.
I have been using Dex VI transmission fluid + Lubegard Platinum 1oz per 1qt of transmission fluid, to raise the fluid additives to meet the Mazda FZ specifications. Been running great on 3 different Mazda Skyactivs, and mine's been supercharged for 12k miles and performing beautifully.
I too plan to drive this car for a while, I am planning on 10-15 years more (@Archerfish not sure I can get 20 more years out of it with the supercharger and multiple racing events per year, but we'll see)
If you don't think it's necessary check my little video, this is with only 40k miles:
small clip, crazy amount of metal shavings in bottom of transmission pan at only 40k miles!Transmission was still shifting fine, but I'm going to a lot of ra...www.youtube.com
That's the wrong kind of fluid.I am using a 35k mile interval with mine. Mazda does not mention a recommended change interval so we are all on our own with this. Old wives' tales are the order of the day here, but with a good dose of practicality in most cases. I don't think you would be hurting anything by changing at 10k, but I'm sure extending that interval to twice or three times as long would be perfectly fine as well. In fact, I don't think changing at 50k would be problematic either. I'll be tackling this again in a few days (hopefully) as I will be reaching 35k since my last change in February last year. I've already obtained the fluid from rockauto.com and this time I got the Idemitsu brand.
My last change I got the Beck/Arnley brand which is still available, but is a wee bit more expensive ($6.20 vs $6.79).
Idemitsu is the OEM for Mazda's fluid so I'll be using that for now, as long as it's available. B/A will be my fall-back.
Calm down. I don't have a Skyactiv-Drive transmission. I have a 2G M6 which uses the FS5A-EL transmission, so M5...Idemitsu, to be exact...is correct for it. But, while on the topic of incorrect fluids...Lubegard? Raise Dex VI to the level of what? Why would you even do that or think that it's okay to do what you are doing, when you can just buy the correct FZ fluid at rockauto.com for $9.36 per quart?That's the wrong kind of fluid.
Skyactiv Automatics need FZ spec fluid, not M5
I'm using the LubeGard additive to raise Dex VI to the level of Mazda FZ fluid
Wait so you've been running with M5 fluid for a while?
what color is it?
