Default Not shifting into 2nd till 4-5Krpm?

I have a transgo shift kit and corvette servo, has been shifting fine for about 3000miles. But tonight after a few runs:
My truck will not shift into second gear until around 4-5000rpm even with light steady throttle. If I let off the throttle real quick it will go ahead and shift into second.... shift feels soft, but doesn't really feel like 1st or 2nd gear is slipping.
2-3 and 3- OD is shifting normal.

Any ideas? Truck only has 7,000miles but I don't think it will pass "under warrantly" with shift kit, stall, and turbo kit.

I did not install a metal accumulator, still has the stock one. If this part fails could it cause these symptoms?

Thanks, I'll check that.
It only does it on the 1-2 shift.

my tranny did the same thing and it turned out to be a check ball valve in the valve body. well no the valve but the seat had come unseated and it wouldnt allow enough pressure to build to shift. if i would go past half throtle while cruising it would down shift all the way to first and bang the rev limiter.
