Anyone change their transmission fluid yet...

[ddlopes]

I'm getting ready to change the fluid in my PTU and RDU on my 13' SHO with PP. I was thinking since I'm there I'd do the transmission fluid. And is everyone using Ford for their replacement fluid? My SHO has 22,000 miles

There are other good fluids as Redline,but personally would stick with the Motorcraft since your vehicle is still under warranty,another note regarding the trans fluid,based on the owners manuel out of all three they seem stiff on only using Motorcraft mercon LV ATF for the trans,based on my 13 SHO manuel,hope this helps.

Agreed on the MC. I did a lot of reading about a replacement and most companies do not make a MC LV replacement. There are only 1 or 2 I could find.  Seems as though the MC oil will be just fine. Can be bought for $5 a quart at the dealer as well.

I think it will be more convenient getting a case of 12 if our cars take 11.6 quarts of transmission fluid.  Motorcraft® MERCON® LV Automatic Transmission Fluid (ATF)

15 quarts will be required if using the 3x drain/fill method.  Without a flush, the torque converter won't release it's share.  So the 3x D/F serves as a good substitute.

So are you saying to drain and refill (3) times?

[SHOdded]

This is based on how much fluid you get out in 1 drain.  If you get out 11 quarts, you are set with just one cycle.  If you get out 5 quarts, you will need to drain a total of 3 times to get the same effect as a flush.  This 3x is true for the 6f50 transmission, and I expect it holds true for the 6f55 as well.

Put in the same quantity you drain each time.  Run the engine for three minutes, with the parking brake on and foot on the brake pedal, work through the gears.  Turn the engine off.  Drain & fill.  Repeat until total of 3 D/F cycles are complete.

I'd say don't waste time and money changing fluid that isn't even broken in yet...

And I'd agree with that, as long as you keep an eye on the color and smell of the fluid.

When does Ford recommend changing the tranny fluid? 22k miles seems low for a fluid change.

[ZSHO]

I think personally 60k is average for transmission fluid change,would not try to exceed beyond that point,like SHOdded mentioned earlier it doesnt hurt to check the dip stick once in a while,at 22k should be a nice cherry color.

Thanks for the detailed instructions!!!
