I am having a problem with 2nd gear on a 4l60e the transmission is fully built, the tranny worked great for about a 1000 miles and 20 1/8 mile pases then i hit it with a big shot of n20 (250+) and it felt good during the run but after that run it slipped into 2nd and once it locked in it was good but during the ride home i lost 2nd completly. I then changed the billet servos with the stockers and 2nd worked again but slipped so I pulled the tranny and toor it down but couldnt find anything wrong all clutches are perfect event the band was perfect i put it back together and now 2nd works but it has a slight delay on the shift so I pulled the valvebody back off thinking it was a accumlator problem but i dont see anything wrong i put it back together with new gaskets again but still not right It does shift and shift hard but its not fast.

I installed the billet servos again and it will not shift to 2nd with them i pulled them back out and noticed there was NO fluid in the servos Why Not?

Thanks for any advise you may have
