Hey guys..
15 taurus sho

I am going to replace the trans fluid.
Maybe the "Motorcraft Mercon LV" fluid in the current transmission.
I am going to replace with "CASTROL TRANSMAX DEXRON® –VI MERCON® LV".

Could this be mixed?
No problem??

Yes it can be mixed, theoretically. Normally, you would use a different brand to TOP OFF existing fluid. To change fluid, always change as completely as possible, either via 4X drain/fills OR fluid exchange. Fluid exchange is the cleanest, but you have to have a shop do it unless you have your own machine such as this one https://www.amazon.com/Mophorn-Automatic-Transmission-Exchanger-Gasoline/dp/B01MZ92N7U/

Thank for reply.

I am trying to replace myself DIY. Without a machine.
I think first, buy 20L cheaper.
Draining the oil and filling the same amount and Start engine P->R->N->D move and accelerator.
Repeat this process up to 20L.
Dirty oil to be discarded is shipped to the shop.

Is this a good way? Please give me some advice.

That sounds about right. The 4x drain/fill will come out to around 20 quarts (maybe a bit more). When I drained mine I was getting about 5-5.5 qts per drain. So by the time you do it 4x that's about 20 qts. My process was let the tranny warm up by driving around, park in garage, shift through gears, turn off car, drain, fill, start car, shift through gears, check fluid level is acceptable (fill as needed), drive around for 5-10 miles, and then repeat the process. Basically what you said but I made sure to drive around between drain/fill to get the fluid well mixed.

Thank you. I completely changed the oil.
