If you completed a required class at that school and you want to avoid repeating it at some cost, you may want to get your transcripts just for that one class.
If they don't require all transcripts, then I wouldn't worry about it. Some schools will count not only your units attempted and completed but also your grades in their satisfactory progress policy, some will only count units attempted/completed.
The feds have a new 6 year limit on full-time Pell grants (what they call 600%), so if it's that you don't want your current school to know you got aid at the old one - the feds are keeping track and will notify the school you are currently attending once you reach 450%.
How any poor grades from another school will affect the continuance of any scholarship you are receiving will depend on the school's policy and what the scholarship requires. Without knowing any of your current college's policies and the terms/conditions of any scholarship aid you are receiving, members here can only make suggestions.
