Chopstick Finished wiring up my custom digital dash I made to replace the standard.

Langdonious Rex The past couple days I've gotten the engine down to a long block so it's ready to get yanked out tomorrow. Pulled the T56 to find the pilot bearing is practically non-existent. Good thing the clutch and slave and other consumables are getting replaced.

LS2-GTO Here's a funny one. Flled up my car for the first time in 2 years and the pump is shutting off even when trickling fuel in. Researched the issue and found its most likely the vent solenoid. So I ordered one 2 days ago. Yesterday I get the Check Engine Light for EVAP Purge solenoid. I feel like the car whisperer. lol

Thanks for the info. I checked them with the exhaust in place so it made it difficult. When I replace the trans output shaft seal I'll check the pinion angles better than I did.

If its not that it may be the trans output shaft bushing, or possibly something with the CV axles. Or maybe an unbalanced shaft. I've noticed the axles rubber boots are dry rotted. Hoping they are not letting dirt in. I'd rather not have to spend the money on new axles at the moment.

Doc-Z IN the past week I...

1). Got the CTS-V sedan rims back from Weldcraft (had fronts narrowed to 8.5")
2). Dropped the rims off to have hub bored to fit the GTO.
3). Saw the progress on the Independant LS9 Supercharger hub I'm having made.
4). Bought a new LS9 S/C lid (old one had a hole drilled through)**
5). Got an e-mail from Mavman that my gauges will be shipping out.
6). Ordered the G-Force Engineering Toe Rods, Heavy Duty Dual Bushing Diff. Mount and crush collar (because my diff leaks)
7). Set the trunk insert in place to see how my design looks (see pic).




** I had the original lid welded, but because the cast aluminum had so many impurities, I started looking for another. They listed online through GM Parts direct as available, but I wasn't going to spend $2,100 for a lid. I managed to find one for less than that, but it took about 4 months to find.

bradnoyes1 I'm in the middle of upgrading a lot of the clutch assembly which has turned into a gigantic "well, while I'm here I should...". SO, I've installed new Hinson poly motor mounts. The originals were completely ripped and destroyed. I could literally lift the engine up while under the car which I know shouldn't be possible. I installed the slave cylinder I got from Tick Performance and their speed bleed line for easy clutch bleeding. I followed that up with a Tick Performance master cylinder replacement. Want to talk about a bitch. That suuuucked. I will say that the customer service at Tick Performance along with their clutch package deals are top notch. I recommend them for parts no doubt. Tomorrow I'll likely install my Monster flywheel, LT1-S twin disc clutch and pressure plate assembly and reinstall my transmission. I'm gonna follow that up with a Hinson Transmission mount and SLP Loudmouth 1 Cat back system to replace my Borla system that is getting kind of crusty. I hope that all of this work will make shifting a lot smoother and I'll be able to grab some gears in the higher revs a lot easier. I also can't wait to wake up every neighbor on my block with that SLP system. It'll be awesome.

TheMealOnWheels Powder coated the front Brembos Electron Blue Pearl to match the rears. Now all I need to do is make a front bracket, get the front rotor bored to 71.5mm and wait for cooler weather to install at all corners!

Ported LS2 Manifold

Installed a ported LS2 manifold. My highly calculated Butt-O-Meter it does pull much better above 3500 rpm through 6500

TheMealOnWheels I stole some wheels and tires from another GTO. Very similar, but better in every way.

ptcerio I took mine in to have the trunk looked at because it usually won't open. The button in the glovebox rarely works, and the remotes aren't much better. I've pulled thru the plastic on the yellow emergency release so that needs to be replaced. Dealership couldn't not get the trunk open. They tested both remotes and the glovebox button and it worked every time

The parts dept said the yellow tab is a discontinued part so I had to buy the whole release cable assembly on ebay just to get the stupid yellow pull tab.

Both are good shifters. I have had both the race and street versions of the GMM. The race handle broke on me, which prompted me to replace the it with a street handle and a Lou's Short Stick. The combination made the shifts very short and precise. I enjoyed that shifter a lot.

The MGW-P is a great shifter, and I like it better. Even with the handle ran all the way down, the throws are a touch longer than the GMM/LSS combo. However, I think I prefer that since it allows a more positive feel. I'd say the throws are more reminiscent of the GMM with the race handle.

Overall, I would pick the MGW over the GMM for a couple of reasons:

1. It does away with the white boot, which just degrades over time and is expensive to replace.

2. It doesn't have the two mounting bolts that always want to loosen up.

3. The height is adjustable.

LS2-GTO Had some vibration from 1 piece driveshaft.
Replaced motor mounts. The originals are about 1/4 shorter. No fluid in them but no cracked rubber and are still 1 piece (85k miles).
Some of the vibration has been eliminated. Hoping new trans mount will take care of the rest.
Will be checking drive shaft pinion angles when replacing trans mount.
Need to replace trans output seal while in there as well.

maradamx3 Replaced the GlowShift electrical oil pressure gauge with a mechanical Autometer. No more "ticking". Much better comfort level with accurate pressure readings.

Exactly. Take out the rear seats first. If you have access to the shop manual, follow the directions and it'll only take a bit over an hour. No front seat removal necessary

Was about 7 years ago. I had the car in a storage unit. Some mice half built a nest in the headliner near driver side a pillar. I had no idea until I took the car out of storage and it sounded like quarters rolling around in the head liner. Turned out to be candies they found somewhere.

Took all the interior out besides the front seats. Washed, cleaned and disinfected. Really was'nt that bad but I was pretty upset considering how sterile I've kept my gto. There was a decent amount of mouse poops under the rear passenger seat plastic. I think they gave up on building a home in the headliner and found a comfy spot in the rear seat foam.

Rarely driven over the last 9 years and the only time I did drive it was during the summer. Was on jacks with the trans out for at least 2 years.

Until you scrape the smurf out of the door panel or the carpet retainer with the edge of the seat rail bracket.

Mine started sagging on the entire passenger's side, so I've used about 3 dozen of these, painted black, to hold it up and not look tacky.

Frisky Medic I just picked up an m6 pedal assembly. Slowly starting to collect the parts for an a4-m6 swap.

LS2-GTO Got the engine bay cleaned up for the first time in a decade.



Ended up slicing my finger open with the inner edge of the fender next to the ecu. 4 stitches. Lol got to love urgent care. Took about 20 mins.

After a few short drives I was unable to shift into 1st, 3rd, 5th and reverse. I realized that I left the adjustable stops in my chinesium shifter. So I jacked up the car, removed the white boot flange and took out the adjustable stops. All fine now. Iím loving the shifter, especially since I paid $50 for it.

Unfortunately my DSS one piece seems to be inducing a lot of vibration from 3500rpm and up. Seems to get worse with higher gears and when on throttle. Driving around normally itís fine. Iíll be rotating the shaft 180 degrees from where it is now. Crossing stitched fingers that takes care of it. Iíll look at the pinion angles as well.

Hereís a shot of my clutch and bleeder lines. Ran them as far from the headers I could.
