Auto Trans Shifter Button Hard to Press?
Note: it appears to shift through all the settings smoothly, it is just really difficult to press the button down when in Park after starting the engine. I have noticed it taking a little more pressure from time to time over the past two months, but today I had to push the gear shift lever forward in Park to get the button to depress.
Is there some other adjustment for the "button"?

Our shifters are now antique. Either your lockout is worn out or it’s crusty and old and needs some lube. First thing would try is removing the shift **** and get a can of spray lithium grease and shoot it down the shifter between the lockout rod and the tube. If that doesn’t help, remove the console and identify the lockout mechanism and lube it.
Here’s a pic of where the cable attaches you can see the tube is flattened the inner lock rod stops above here, inside the mechanism by the shifter pivot. Below that you can see the outer tube and the lockout rod inside the tube
Unwanted advice: then I would order a nice **** and C5 adapter from twistedshiterz and toss the homely OEM **** for a nice ball ****. They have many to choose from. C5 specific search on their site gives you all the options and the lively adapter is included in the price. Easy to install. Then you just push down the entire **** itself to unlock. What a great upgrade and very affordable. Love mine. Check them out.

That’s good to hear! I will give these suggestions a try. Thanks

C5 CORVETTE AUTOMATIC SHIFTER CABLE "COTTER PIN & WASHER" MODIFICATION
======================================== ========================================
This guide outlines the permanent "bulletproof" mechanical modification to
prevent the factory automatic shifter cable from ever falling off the linkage
pin again, even if the internal plastic bushing completely disintegrates.
REQUIRED PARTS & TOOLS:
* Cordless drill or right-angle drill (for tight spaces under the car)
* 1/16" or 3/32" high-quality cobalt or titanium drill bit
* Center punch and hammer
* Stainless steel cotter pin or R-clip (sized to match your drill bit)
* Stainless steel flat washer (with an inner diameter that fits the pin snug)
* Small can of cutting fluid or 3-in-1 oil (to cool the drill bit)
* Pliers (to bend the cotter pin legs)
--------------------------------------------------------------------------------
STEP 1: PREPARING AND CENTERING THE BALL-PIN
--------------------------------------------------------------------------------
1. Disconnect the shifter cable eyelet from the factory metal transmission or
shifter assembly ball-pin linkage arm.
2. Clean all grease and road grime off the metal pin using a rag.
3. Take a center punch and tap a small dimple horizontally right into the very
tip/nose of the metal ball-pin, past where the cable sits. This dimple is
critical to keep your drill bit from walking off the rounded surface.
--------------------------------------------------------------------------------
STEP 2: DRILLING THE HOLE
--------------------------------------------------------------------------------
1. Apply a drop of cutting fluid or oil to the tip of your 1/16" or 3/32" drill
bit to prevent it from overheating.
2. Hold the drill perfectly level and straight. Using steady, moderate pressure
at a low speed, slowly drill a hole horizontally completely through the nose
of the factory metal ball-pin.
3. Take your time, let the bit do the work, and reapply oil if necessary. Once
through, clean away any metal shavings or burrs with a file or sandpaper.
--------------------------------------------------------------------------------
STEP 3: FINAL MECHANICAL ASSEMBLY
--------------------------------------------------------------------------------
1. Slide the factory plastic shifter cable eyelet (with whatever bushing material
remains, or a fresh replacement) completely back onto the drilled ball-pin.
2. Slide your stainless steel flat washer over the nose of the pin. The washer
acts as a physical wall, keeping the wider plastic cable loop trapped.
3. Push your stainless steel cotter pin or R-clip straight down through the
newly drilled horizontal hole.
4. Using a pair of pliers, bend the legs of the cotter pin backward around the
pin to lock it permanently into place.
Even if the internal bushing completely dissolves down the road, the mechanical
washer and cotter pin physically trap the cable on the arm, guaranteeing you
will never be stranded in gear again.
Hopefully that helps someone avoid what I encountered a thousand miles from home.
