Default No second gear

Hi everyone this is my first time at this. I have a 1999 Suburban 4x4 with a 4L60E, put shift kit in some years back. Started shifting funny 1st to 3rd. Removed valve body found broken 1-2 accumulator piston. Replaced both 1-2 & 3-4 accumulators. Replaced valve body separator plate. Cleaned and inspected valve body. All electrical components checked out. Still shifts 1st to 3rd then OD and lockup. No slippage in any gear but second. Help

Does it shift into second if you ease off the throttle?
