Trans slipping... upgrade to PI gearing with reman trans?

So my transmission is starting to slip a bit on 2-3 shifts under WOT.

2013 SHO PP purchased with 46k, unleashed 93 octane 3 Bar tuned at 56k.

I'm thinking I might eventually need a rebuild and found that remanufactured might be a better route.
I also found that base SHO's have a 2.77 final drive, PP's have a 3.16, and Interceptor sedans have 3.39!
I was wondering how difficult it would be to source a PI final drive to install on my '13 PP...
Anyone know how difficult that would be or if maybe just finding a complete PI trans and swapping it out. And if swapping is a better option, would the paddle shifting function still work?

I bet everything works...i would love to do that...i think swapping just the final drive is easy once the trans is out

Great idea if you're gonna have to replace it anyway...

Unless the 14+ Interceptors have a different final drive ratio, I wonder where you received the info that they have a 3.39 ratio.  Attached is a segment of my car's build sheet showing the 3.16.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

I know this is an old thread.

The question would be. Since the PI gearing is "Taller" . Would this create less stress on the trans and such so you might not see the torque errors and maybe trans shifting problems ?

Wait, isn't it shorter?

Macgyver

Well yeah whatever the term is.

But since gearing makes "Work" easier. Couldn't this solve a little of the "too much power on launch" that the SHO has ?

I thought about this myself, but since decided that the payoff vs. time and money weren't in line. 3.16 to 3.39 just isnt a big enough difference to me. 3.73 on the other hand...a man can dream...
