Default Broken reverse lockout

Hi All,

the reverse lockout mechanism on my 91 C4 is not working and requires periodic retightening. It appears to be broken, see below.





Is this the correct part? is it a fairly easy fix to swap it out? Thanks!

ok looks correct; I have ordered it. looks like it slides off/on pretty easily. Anyone done this before? any tricks/tips?

I can’t seem to find much about this and the part isn’t even listed in the FSM!

Looks like it should just slide off/into the boot? should be a super easy fix

The only real challenge is that it can be a wrestling match to remove the wedge that secures the **** in some cases. Vise Grip, and upward persuasion should get it done.

Live well,

yes, if it gives you trouble, take roof off, straddle the center console, vice grips on the “wedge”, screwdriver through the vice grips and pull up on the screwdriver!

be careful and be sure you know where you and the tools are going if something lets loose!

I also assume similar setup and tapping upwards on the screwdriver with a rubber mallet may work too.

When reassembling, you'll do yourself a major favor if you go easy pushing the wedge back into place, and also go easy with the set screw that secures the lift ring. Be gentle with both, and you'll avoid unnecessary future trouble.

a few small taps so you can get the cap back on. The **** screws on and the wedge just locks the **** so it can’t unscrew/twist.

oh interesting. I figured since the wedge was so hard to get out it would require similar force to go back in

NO!!!!! If you've NOT removed it yet and you know someone with a small 'slide hammer style' dent puller/seal remover device it's ideal for the removal. I don't know that maybe some of the retail auto parts stores might loan/rent one or not.

wow! that little wedge was a PITA. Used two screwdrivers to leverage it out and some gentle tapping to put it back. it’s also so much longer than i expected.

New part from dino’s corvette salvage works great. only complaint is that it lacks the shift boot retaining ring. So as you can see, I’ve been relegated to a zip tie.

At least you used a black one.

Congrats. Now go drive it.
