2015 Mustang Gt Fluid changes

Just got a brand new 2015 6 Speed GT. At 1500 miles I plan on changing the oill, diff and manual transmission fluid. Anyone have a write up on the diff and manual fluid changes? Is there anything special I need to know? Thanks in advance!

Engine oil I can understand, but why change the diff and trans fluids so early?

You guys don't think changing the transmission and diff fluid is a good idea early on?

2015 Mustang Gt Fluid changes

I'd check it to see how it looks, but isn't really necessary to change them this early. Unless you want to, if that's the case upgrade to better fluids.

Transmission fluid is a must. 1 thing in helping the mt82 problems. I did mine the day after I bought the car.

Does the trans and diff fluid have a fill and drain plug or do you have to take the housing off?

Are you racing the car at a track? Then all the standard replacement intervals don't apply. Most people I know will change all fluids after a long race day. Never hurts other than your wallet. Of course you need to add new brake pads and tires too.

The stock differential cover has a drain bolt, but not a fill bolt, or at least on the 2011 to 2014's it was this way. Might be a good time to install a Ford Racing differential cover, as it does have a fill (and drain) bolt.
Not sure on the new split axles where the fill is for the differential if the cover does not have one. On the earlier solid axles, the fill plug was on the drivers side axle near the differential.

To the original poster: apologies for some of the rude answers. They were removed.

It doesn't have a full plug on the snout like previously?

I did not know this.

So for my 2015 GT, also considering switching out the fluids on the MT82 and the lim slip diff (Royal Purple). Did you ever go through with this? Any issues?
