I bought 2000 Trans Am ws6 has new automatic transmission with new wire harness. The guy that installed it messed it up or something the car can go into gears without applying the brake to start. I like to see if anyone know if I am missing something to get this correct to apply the brake to go into gear. The car can be sitting and just put it into gear without the keys in it.

 

Was this a M6 to A4 conversion? This wiring diagram should help.
