Check the cluth fluid reservoir. If the CSC us failing, you will notice a low fluid level and this is an indicator of a leak.
Did you replace the pilot bushing when you had the trans out? A failing pilot bushing can cause the input shaft on the trans to sag and cause difficulty shifting into gears.
