3000 stall, firm shifts gone

I had installed the TF-2 kit in my 727 before i got the 3000 stall TC and it shifted NICELY. firm, quick shifts....only problem was that it shifted into 2nd WAY too early.....

so while i had the engine out to paint it and install TTIs and the TC, I put in the split shift fix and used the 1000 rpm split fix spring.....

it seems to have solved the split shift problem, but the shifts are very soft....quick, but soft...before, with the stock converter, it jarred me back in the seat every time it shifted.....now it's about as firm as a stock shift....the quickness is there, just the firmness has gone....

is it a sloppy converter, and maybe i need to get in on up in the revs and see if is shifts firmer????
