Hey fellas, pretty much like the title says, car is a LS swapped 1987 El Camino. 5.3 motor and 4l60e trans. Cars been working fine for year and a half now, but recently within the last few weeks I noticed I've been able to switch from park to reverse or drive without pressing the brake.

It is a column shift, I figured it's something either in the column or in the brake pedal. Any help would be appreciated, thanks

Yeah, somewhere in the mid-2000s GM decided to start making automatic cars with "press brake to shift out of Park" interlocks. Heck, with the push button start-up cars now you can't even start the car without your foot on the brake. Safety first, I guess.

But no G-body ever was made with any brake pedal requirements to either start or shift the car. For us old farts, most G-bodies were made with all the simpler things we got used to from the muscle-car era, but without the muscle part.

It's so you can floor it and just take it from Park to Drive. Easy Peasy. aka "U-joint strength test." :)

My '99 GMT400/OBS series truck requires depressing the brake pedal before it will shift out of Park/into gear so earlier than the mid-2000's.
