This write up is for when you lose all your gears. Your shifter become completely gearless and sloppy. After replacing the roll pin, shifter should be very tight just like a brand new shifter.
EDIT: Here is a vid I made with a temporary fix for those that feel like they are about to be stranded and don't have the time or tools to do the complete fix.

Ok, first you need a few tools:
7mm socket
10mm socket
1/2" socket
ratchet
hammer
Roll pin pusher
Car jack
lug nut wrench
New Roll Pin- 1" long by 3/16" thick
You can purchase the roll pin pusher and roll pin at NAPA or any other auto parts store. And you can use your stock jack and lug nut wrench.
First- Unplug battery with 10mm socket and Jack up car and remove wheel.

then remove nuts that hold the fuse box down. 1/2" socket is needed.


Next you must begin to dissassemble the fuse box. 7mm socket is needed. The next few picks will show the process of disassembling the fuse box.

10mm socket needed here also.

Slide ECU out of holder and place to the side.


7mm socket needed here to loosen all the bolts.

then pull top of fuse box up to show the bottom part all sitting there.

place all the different connections to the sides.

at this point you can see the linkages.


Here is the hole where the new pin goes.



Now you use this roll pin pusher to push the new pin in. Tap with a hammer.

And this is my shattered roll pin beside the new roll pin. As you can see it is stretched out as well.

Took me about 30min on my own. Good luck and happy modding

Excellent write-up. Mine broke back when it was still under warranty so I didn't need to bother with it myself. It's good to know for next time.

wow this IS a great write up. after i saw u posted urs went out, i got a lil worried it might happen to mine in teh future. how much is an estimated dealer repair for this? but great write up. im sure this will help a ton.

you made this entirely to complicated.

Doesn't seem too bad to me Why, do you know a shortcut? Might want to suggest to use a jackstand.

no, my dealer made it to complicated. The removed the tranny and broke my slave cylinder. I got a brand new clutch out of it at 35k miles though.

this isn't complicated at all. Very simple. I was just making sure ANYONE could see what I did, step by step.

jack up the car, on the driver side only.

pull of the tire and the linkage and roll pin are staring you rite in the face.

much simpler.

\BlkCSS not to be rude, but you obviously have not done this much. Ralliartist did it the way professionals do, shortcuts lead to trouble; they say in the great midwest of the USA "there is never enough time to do it right, there is always time to do it over."

i've been thro 4 or 5 roll pins, i've gotten several PMs about my methods on swapping it.

i assure you i've done this more then any one.

last time the pin was replaced with a bolt, this was done by my dealer, with approval from GM tech cntr.

the "professionals" have more then one way of doing something, when the issue repeats its self several times they find easier and more accommodating ways to do the work.

if you want to waste your time taking this route, go for it.
