Corvette C6 Automatic Shift Knob Removal

A6 Shift Knob Removal

I recently installed a leather A6 shift knob (and other leather pieces) from DownSouth Vettes and

thought I would post a few pictures to help anyone else trying to remove their shift knob. The

other interior parts are similar to the M6.

 

The A6 knob can be a bear to remove if it is not aligned perfectly with the retaining ring and they

are easily damaged. One of the leather venders on the Forum told me he did not sell A6 shift

knobs because too many were damaged during removal.

As most of you already know, Gerardo’s work is superb and well worth the effort needed for

installation!

I had previously downloaded GM’s instructions for removing the A6 shift knob and thought I

was good-to-go when the new shift knob arrived.

 

A6 Shift Knob Removal from GM:

Control Boot Tip

• To remove, grasp boot near shift knob, rotate boot clockwise from 12:00 to 1:00 position. Pull

boot down off shift knob.

• To install, push boot onto shift knob. Rotate boot counter-clockwise from 1:00 to 12:00

position in order to secure boot to shift knob.

2 Shift Control Knob

Tip Pull knob up off shift lever. Considerable effort may be required to remove knob from shift

control lever.

 

The engineer who designed the A6 assembly was called more than a few choice names as I tried

to follow the removal instruction and nothing budged. I realized later that the A6 shift knob is

not difficult to remove if you know how the knob and retaining ring fit together. GM’s

instructions just need a few little “details” added when you try this the first time.

GM’s instructions were confusing because the OEM shift boot is attached to the shift knob

retaining ring AND the retaining ring should be rotated but NOT pulled down with the shift boot

IMO (YMMV). The shift boot on my 2008 A6 was attached to the retaining ring with a nylon tie

wrap. Unfortunately, you can’t see any of this with the parts installed.

The following pictures shows how the shift knob is locked to the shifter shaft and how it can be

removed:

The first picture shows the top of the shift knob retaining ring (shift boot fits over this ring).

If you look carefully you can see the interior posts that align the ring and the channels that allow

the shift knob to be removed.

A close- up picture looking from the bottom of the ring shows the two tapered channels cut into

the interior of the retaining ring in more detail. These channels allow the A6 shift knob to be

removed when the ring is rotated to the 1:00 position. The deepest channel cut is at the bottom of

the retaining ring.

This picture shows deep indentations at the base of the retaining ring where the ends of the

shifter prongs lock when rotated to the 12:00 position.

The next picture shows the two prongs on the shift knob that lock into the bottom indentations of

the retaining ring when it is rotated to the 12:00 position. When the ring is rotated to the 1:00

position the prongs align with the channels and the channels provide clearance for the prongs to

be pushed outward as the shift knob is removed by pulling upward. If you pull down on the

retaining ring the ends of the prongs are pulled from the deepest cut of the tapered

channels to the shallower ramp and they will not be able to flex outward and will not

release properly.

You can see the quality of Gerardo’s work in this picture.

This picture shows what happens when you pull down on the shifter boot and retaining ring and

apply “considerable effort” while pulling up on the shift knob as mentioned in the GM

instructions.

Along with the channels, the retaining ring and shift knob have posts and grooves respectively

that provide alignment. You can see the groove on the shift knob for the retaining ring post that

allows the ring to be rotated from the 12:00 position to the 1:00 position.

 

With the ring rotated to the 1:00 position and NOT PULLED DOWN, the shift knob can be

removed by pulling up with reasonable force. You will be rewarded with the welcome sight of

no A6 shift knob! Please note that you see the retaining ring installed in the shift boot in this

picture only because I wanted to see how it fit into the new DownSouth boot before I installed

the new knob.

Again, you can see the quality of Gerardo’s shift boot in this picture.

Installation is easy if you push the retaining ring back onto the knob at the 1:00 position and push

both down onto the shifter shaft. Rotate the ring back into the 12:00 position to lock the knob

and replace the boot on the ring. Be careful! The shift knob will also lock on the shaft when

reversed (button to the rear). You won’t like that although it will still operate.

This will at least help you visualize the parts that need to be removed.

Installation completed. I will try to post a new picture that shows the quality of Gerardo’s work

better. He uses a heavy grade of leather as used by BMW and the quality and stitching are

excellent.

You can now call Gerardo to order your new seat covers.

I installed a Kenwood DNX-7100 the same time as I installed the leather parts and it has a great

navigation system by Garmin. The system shows weather conditions and traffic reports on the

navigation map and you can look up conditions for cities along your route (also plays XM,

DVDs with great resolution and gives stock quotes. )

Corvette C6 NPP Retro-Fit for Multi Mode Exhaust

NPP in a box, a set of NPP mufflers and a M2W switch will give you an incredibly easy way to have just the sound you want, when you want, if you have a pre-2008 C6. In my case, throw in a set of LG headers, and you have rolling thunder at the flick of a switch. The combo of the headers and the NPP in Wild gives you AMAZING sound and “HEY, LOOK AT ME!!!” volume…the tonality and sound is that of a NASCAR stock car at WOT outside the car, yet quieter and less drone inside the car than the GHL exhaust I was so fond of. The install is very straight forward, easier with a lift, but as Ed has shown with his car, you can do it on jack stands. Here are some pics and descriptions of the step by step process; you will receive complete illustrated instructions with your purchase.

NPP Mufflers waiting for Install

Factory Exhaust Removed

Run the Vacuum tubes through existing frame locations

After dropping the rear sway bar, snake the NPP mufflers up and over

Attach the pipes to the mufflers

Connect the vacuum hoses to the NPP mufflers

Make sure your muffler pipes are straight and level

Muffler hardware done and vacuum tubing run

And of course, a quick run with Ed’s Polishing kit

That’s all there is to it…..All that’s left is to go out there and have a blast with your new found customized sound.
