You can upgrade and it's "worth" is relative to your intended use.
The primary differences between the package offerings in your model year are the added auxiliary coolers.
Those additions, in terms of most owners opinions IS "worth it".
They can certainly be added post sale on a "Non PP" optioned SHO, with the exception being the PTU/Rear Diff cooler as IIRC portions of the system are designed into the rear axle assembly.
Expense is a factor, especially if you're planning on the "stealership" performing the work as they'll likely go by book hours, assuming those labor hours are even posted in there as a guide.
There's also better shocks and "sway-bars," / suspension on the PP! It IS worth every bit of it as a package with the combination of 3:16 gear ratio, suspension, engine/trans cooler, etc. However, it is NOT worth it if you already have a brand new non-PP SHO as you will have to trade it in because there's just no way to actually make a non-PP into a PP. It really is a factory option and not an aftermarket mod.
Just to be clear I wasn't saying the pp doesn't have advantages. There are reasons people opt for it and at what, $1995 its not a bad deal if you don't want drivers aid. But as you say, adding it later is going to be very expensive even if possible.
Still going to state, for the vast majority of owners who just want a fast comfy 4 door you're not missing much. The car already handles very well (esp for such a pig) and daily driving/ drag racing isn't getting an advantage with the coolers.

Rather than taking offense to my post there Mr. SHONufFordTough.....
You should understand that my comments come as a result of not only personal experience, but also that I am knowledgeable in many aspects of the platform.
It also helps that I have been THE leader in mods on the late GEN model SHO's, and my achievements, and durability therein, speak for themselves.
As I originally stated, "You can upgrade and it's worth is relative to your intended use".
The auxiliary coolers are of immense benefit. I have plenty of "How-To" tutorials that not only help fellow SHO owners out in installing these items, but also details the price of those components, and more importantly, the benefits of said additions.
In relation to any other mods one performs, the expense therein is relative to the benefits achieved.
Those added components are beneficial not only for those tracking the car, but also for those who DD their SHO's and drive them spirited fashion..
A tune will do jack **** for cooling, other than turning on the cooling fans at a sooner set temperature, and/or to cycle at a more frequent rate.
I can easily quantify the differences and benefits of a mere tune, versus the addition of the added auxiliary cooling components.
When you're ready to stop being butt hurt simply cuz I called you out on your (unqualified) opinions, and ready to listen openly, without bias, then I'm ready to continue the conversation.
In the interim, my original post, and comments stand. The addition of the auxiliary coolers are beneficial, and it all depends on what (or how) one chooses to have them installed as far as the ultimate expense outlayed. So to the OP, yes, there is of benefit.
I'll also added, that there's been plenty of evidence that once a tune is applied, the slight differences in gear ratios also don't mean jack diddly do.
Carry on good people.![]()
Not looking to argue with you...
But to answer some of your questions directed towards me.
Digging would be a reference to junk yards and rebuilders of said parts aren't calling me.
I'll agree that the ptu cooler probably isn't doing the job to cool said parts like it should, but that's not even an option to add on...it's an entirely different unit that'd be bought separately. More likely than not, the fluid is overheating and being pushed out of the vent and most are being told it's a seal before Ford admits to the faulty design (assumption, take it how you will)
Why would aftermarket companies not be all over these cooling systems? The same reasons we have a hard time getting aftermarket parts, sheer #'s produced and the fact that they'd have to spend a crap load of money on R&D to produce a product that already exists for a small market.
And, everyone isn't in such a "finite" situation as yours and have wrenching buddies or the ability to do it themselves, which cuts the price down considerably.
I think there's a reason my car retains its "freakSHO" status, it doesn't get driven as hard as some would think. So when the time comes to show its peppiness, it's up to the task. That being said, I'll defer to my black trans fluid from the previous post.
If a cooler can get someone 10k extra miles before the breakdown of fluid, that could potentially save them a large cost.

So you are saying these are designed for track use but wouldn't help in daily driving situations...now I'm lost
