Trans-go shift kit

Does anyone have experience with this product or one like it?

http://www.transgo.com/products.php?category_id=104&product_id=219
There seems to be precious little information or perfomance parts available for the 4T45 automatic transaxle. Is it really so good that there's no room for improvement?

That appears to be a set of 5 stock replacement parts, (springs and valves for 5 units) not a "shift kit".

Ok, so it's more of a kit for professional transmission shops.

Thank you

It looks like Trans-Go gives you a selection of a different valve to go with it's spring. There would not be 5 of the same valve/spring combo's in an aftermarket shift kit.
