Google "48re detent bullet".
Have to drop the valve body to do it.
Before you go for that make sure the latch switch on steering column is good first.
The latch switch would unlatch the shifter cable after you hit the brake pedal and let you get out of park.
With the VB on your hand after installing the detent bullet, make sure it will get out of park easily by operating the rooster comb by hand.
If not you have to smooth out the notch profile (from park to reverse) on the comb a little bit.
