1999 Tahoe not going into gear

[Eyegore]

Help I just finished replacing the power booster on my sons 99 tahoe 4x4 w/ automatic. I slipped off the booster w/o disconecting the master cylinder, did have trouble getting the retaining clip off the pedal that holds the push rod and brake switch, but now after it starts i cannot get it to go into gear, its jamed in park and will not budge I press the pedal down but nothing. Did I miss something?

make sure the brake switch is still attached ity might even be out of a ajustment hit teh brakes and see if the brake lights come on i am pretty sure you need to look at the swtich on teh brake pedal under the dash. also make sure you pluged that switch back in

Sounds like you knocked something off in the Brake Transmission Shift Interlock system while you were struggling with that clip. Most likely the cable that connects to the column or the pedal. You can override this to verify this is the problem by turning off the ignition switch (not LOCK, just off) and remove the TURN-B/U fuse to remove the battery voltage to the solenoid. Don’t run without this fuse or you won’t have turn signals.

Thanks for both your suggestions, truckdude239 nailed it had to repalce brake light switch.

Thanks again.
