WHY IS IT HARD TO SHIFT FROM PARK TO REVERSE OR DRIVE ?? on 2000 GMC Yukon Denali

HAVE TO PUSH BRAKE PEDAL ALL THE WAY DOWN AND RELEASE SLOWLY. OR MAY HAVE TO DO SEVERAL TIMES TO GET IT TO RELEASE AND THEN IT SHIFTS DOWN. WILL A SIMPLE TRANSMISSION SERVICE TAKE CARE OF THIS?? THANK YOU FOR YOUR HELP

Hello it seems as if the brake transmission shift interlock is malf.this switch is also known as the transmission shift lock control.The transmission service will not fix this problem because this is a electrical failure the system needs to have a diagnostic performed to find the exact problem.
