    8l90e shifting

    Lt4/8l90e engine os 12670948 trans os 24280477 when placed in manual first gear, transmission shifts normally. when placed in manual second, trans shifts normally. Are there settings i can change so it will stay in manual first or second when selected? trans shifts normally in drive. Thanks in advance for any help
