I bought a 2011 taurus sho about a month ago. two weeks after I bought the car a bearing in the ptu went out. I replaced the ptu myself as I am a ford technician. When I bought the car the temperatures outside were in the 60's and it would launch hard with no problems. After I got the car back the temperature outside had gotten significantly colder. Now when I accelerate at wide open throttle from a dead stop in a straight line or turning the car has wheel hop. I am wondering if this is normal for the cold weather or if something could have been screwed up while replacing the ptu? I had both roll control mounts and the rear subframe bolts out to replace the ptu. The car is completely stock as far as I know.

Sounds fairly normal. Cold weather makes more power and rubber harder on the tires. I notice wheel hop more in cold weather personally

I agree, I'll bet it's the colder tire/road surface.
let's hear more about the PTU replacement. You didn't have to drop the front subframe? Did you happen to take a peek inside the failed ptu? Or look at the oil in it?

Another good reason to have engine/tires warmed up before going WOT 
Maybe someday in the future they will monitor tire/surface temps also! What tires? How much tread remaining?
X2 on more info re: the PTU replacement.

Very normal, coming from a tuned SHO I can say. Cold weather has put a stop to brake boosting launches for sure. Also getting the tire hop when shifting into 2nd from an aggressive take off. Love the power created from the cold air, but need a well prepped surface to take full advantage of.

The PTU replacement wasn't as bad as I thought it would be. The rear of the subframe has to be lowered and the engine has to be raised a little bit. I didn't look inside of old ptu but I can tell you the fluid was black and was very thick almost paste like.
Thank you for the input on the wheel hop issue. I guess I was just worried that something was wrong with the new ptu or transmission.

Good to hear that it wasn't too bad. Just lowering the rear of the front SF is a whole hell of a lot better than having to drop the entire thing.
The report on the fluid is pretty disturbing, but seems to be the common denominator with failures. Even owners who've performed PM and swapped out the putty...er...fluid have all reported essentially useless oil in the unit. I think it is safe to say that after so long (not long at all), the factory fill becomes essentially useless, burns into nothingness and basically loses 100 percent of its viscosity.

Update: I had my car on the hoist tonight after work to do an oil change and decided to inspect a few things and noticed both the rear shocks are leaking and I checked my tire pressure and all of them were down about 4 psi. I am wondering if either one of these issues could contribute to my wheel hop problem?
Somebody asked what kind of tires I was running. To answer the question they are goodyear eagle rsa's. and are better than half tread.

Rear shocks have been a common issue recently. Not a fan of that tire personally.

I've been noticing this right after the exhaust upgrade . The 1st to 2nd gear shift feel very aggressive .SHOnUup said:

How about the BF Goodrichs G- Force Comp-2 ?SHOdded said:
Being a UHP summer tire, and with this statement "g-Control sidewall inserts featuring up to a 40% higher sidewall stiffening structure to improve lateral stability and cornering precision", I would say the sidewall is as stiff as or stiffer than the Super Sport. Since TX has widely variable weather depending on where you are/where you primarily drive, your choice of tires likely would change accordingly.
