Table schema:
CREATE TABLE table_name_97 (rd_7 INTEGER, rd_8 VARCHAR, team VARCHAR, position VARCHAR, rd_6 VARCHAR)

Question: What is the sum of values of Rd 7 with RD 6 less than 48 and Rd 8 less than 4 for TC Motorsport in a position greater than 1?
SQL: SELECT SUM(rd_7) FROM table_name_97 WHERE position > 1 AND rd_6 < 48 AND team = "tc motorsport" AND rd_8 < 4
