Is there any shift kits or any other performance upgrades for the multispeed auto used on the 4.7's?, or is performance tranny fluids about it?

Damn some people can be jerks on here. :p
I assume he was asking a legit question. He noticed the STOCK programming uses TORQUE MANAGEMENT during shifts. While it feels like a solid shift (and it is) the engine reduces torque during the shifts. Chrysler had been doing that on the V6 electronic tranny's and then on the newer 45 RFE tranny's.
A thing called a SuperChips programmer is all you need. I know there is a mechanical version now that requires removing the drian pan and getting into the valve body a bit to replace springs and some cups or something. But half of their secret to the shift improvement is they cut and splice in a resistor or something in their to trick it to reduce/remove the torque management during shifts.
I always document my mods and experiments (good and bad) with videos and here is one that demonstrates the AWESOME shifts you can get from the 45RFE (or in my case a 5-45RFE) tranny just by a programmer. And it really does it once I did the lower gears and LSD diff....
chirping the sh*t out of the tires
It's a 4 meg Real PLayer video but worth downloading.
I never have removed my tranny pan.

I'll bet your filters are full.
They are real filters, not just a screen like in so many other transmissions.
They both have built-in bypass and anti-drain back features as well.
Also, the pan magnet is a tiny, cheap, weak, useless thing, so doesn't trap metal particles well. Anyone who drops their 45/545-RFE pan should replace it with a much stronger one.

Geez I hope not!
I will have to do a tranny service soon I guess.
This weekend my truck will be hauling a 8,000 Lb load to Flagstaff! It will get a good workout on them hills too!
Time like that I am glad I got a Mid Sized TRUCK instead of an imitation truck like a Honda :p
