Rebuilt 60e slips 2nd in high rpm My 4l60e in my firebird was just build by me and an experienced builder. It's been fine for 2 months, but just today I noticed it slipping when it gets high in the rpm but only 2nd gear. The weather just turned cold, but the trans temp was around 140. I have noticed that it will not chirp second gear like it used to also.
It has a new drum and wide carbon band, would a shift kit or longer servo help out?

Factory servo, it's a brand new wide carbon band i hope it isn't wearing. Would the transgo hd2 shift kit apply the band a little better to keep it from slipping? The slipping just started today, ill go easy untill I find a fix.

You can check the servo end play by pressing on the cover with a crowbar. The end play should be .075 to .125 or about 1/16 to 1/8".
Another relatively simple thing to check is the 1-2 accumulator for a cracked piston. The stock plastic piston should not be reused - get an aluminum one instead.
As monte383sbc suggests, post the type of servos. Your experience builder should be able to check line pressure too. Was a larger boost valve installed?

Just a bigger boost valve would be a good mod. While the Transgo HD2 kit has one, the Sonnax one is available by itself and is often better because it seals with o-rings.
