Hey, all! New to the W-Body forums and learning so much about these cars! I recently purchased a 1996 Buick Regal GS coupe from my grandma, who bought this brand new in December 1995 from Van Atta Buick in Vestal, NY. It was a daily driver for 2 years (has not seen salt since 1998), and became an exclusive summer driver after that. It did, of course not always see road time. They always had a couple other cars that they drove around, and sometimes the Regal would sit for an entire summer (or 2) without any new mileage on it! It was always kept in a enclosed, heated garage and waxed 2x a year (even if the car didnt physically go anywhere that year it was still cleaned up)! Fast forward to 2026, the Regal had been sitting for 6 years, not driven, merely tucked away, covered up, and forgotten about. Grandma decided she wants to sell the Regal, as sitting is doing nothing for its value (as it sat it had just over 29k miles on it, WITH THE ORIGINAL TIRES STILL ON IT). We came to an agreement on price and it became my car! Purchased just after July 4th, I simply gave it a really good bath, buff, polish, ceramic coating, and some little maintenance items before taking this absolute treasure of a survivor to local car shows, and simply enjoying the ride quality of a practically still new 96 Regal GS Coupe. Finished in the beautiful Dark Toreador Metallic with ruby red leather interior WITH the 3800 V6! I wonder how many of these are still out there, with this color and option combination and mileage! Check out the photos, admire it's beauty! Attached is also an odometer photo after I got the car home to me.

I have been passed down a 1992 Cutlass Supreme from my father in law. The car has 80K miles and runs like a champ, however it has a bunch of small issues on the interior and window gaskets that are keeping it from standing out. He is nearing 90 and I am trying to clean it up for him before he passes to let him ride in it again. He bought it when he retired and it has sat in his garage for about 10 years. I need a few parts so I hope that this community might be able to point me in the right direction.

Greetings form Peru justa wan to share my new preservation project with the community. it's a legitimate 1991 OLSDMOBILE CUTLASS SUPREME INTERNATIONAL SERIES COUPE ( X-Code 3.4L DOHC TWIN Dual Cam) with only 25,857 original miles Here is a crazy part of its history: Someone in the past installed a 3rd-generation LPG system on it, which caused it to stop running back in the day. Because of that mistake, the car was left sitting for decades, sleeping like a time capsule! A blessing in disguise for me. Everything from the LPG system has been removed from the engine bay, except for the 16-gallon tank in the trunk and the exterior filler valve, which I will remove and patch later. The great news is that the engine is finally up and running again, and it sounds great! The interior is full Burgundy leather with the premium AQ9 bucket seats, and the green digital cluster works perfectly. Right now, I'm doing a complete brake overhaul (the front calipers were seized) and getting ready for a full fluid flush. New water pump and mechanical thermostat are going in next. My approach is mechanics first: make it move, shift, and brake safely, then deal with the bodywork. Glad to be here, and I'd love to hear your thoughts, technical tips, and recommendations for bringing this 90s unicorn back to life! WhatsApp Video 2026-.mp4 WhatsApp Video 2026-06-28 .mp4

After seeing the code list, my thoughts are now that you're either going to be dealing with a bad sensor somewhere on the 5 volt reference B side possibly shorting out internally and taking down everything else, a chafed wire or corroded connector somewhere.....or even a failed PCM. I would ignore the harsh shifting and random no-start at this time, since those are likely just symptoms of the overall issue. 5 volt sensors generally work based on a voltage output to represent a particular value. Take your range sensor. It would receive a 5 volt signal, and would output a different voltage to represent PRND321. If the 5 volt signal going into the sensor is being pulled down slightly and randomly by something else, the output voltage will change, and the PCM can interpret those changes as different reported shifter positions. If the vehicle is off and its reporting something other than park or neutral....it won't start. It may also begin shifting funny as it no longer knows which position the shifter is in. If it were me...I'd be starting my troubleshooting on that 5 volt reference branch first.

Welcome. That car looks amazing! Definitely somewhat of a rare car, even when new. Seems like the Regal coupes were fairly out of style by that time. Having those wheels makes it even rarer. Can’t say that I’ve ever seen a 95-96 coupe in person, but I still see the odd sedan out and about. Definitely have not seen any Regal in person with those wheels on it either.

Hi, I have a 92 Chevy Lumina Z34 automatic with the V6 DOHC. It's all stock. I am new to fixing cars and got it a year ago. Any tips or suggestions is appreciated. The current thing I'm working on it wiring and brakes.

Nice to see another Z34 being kept alive. If you’re new to working on cars, I’d focus on getting a solid maintenance baseline before changing anything: fluids, belts, hoses, grounds, and any old or brittle wiring/connectors. Since you’re already into the brakes, I’d check the rubber hoses and hard lines closely too. And if you don’t know when the timing belt was last done on the 3.4 DOHC, that’s definitely something I’d put on the list. Take plenty of photos before unplugging things and tackle one issue at a time. Makes troubleshooting a lot less painful.

Adding some pictures because it is a very rare and very fascinating setup. Lots of pics of the engine bay exist, but Ive never found any of the engine assembly on the subframe. Enjoy!

I suppose if I were to go the route of a new heart *exotic* transplant the LFX from the Cadillac ATS & the 6T75 trans would be my choice of powerplant. I won't sneeze at a 320 hp na V6.

If I were to guess... the 4T65E in the V8 cars was a pretty tragic weak point so maybe he's tired of cooking those?

The 3.6 is quite an engine. The 6T70E seems to be a pretty-fair transmission, although it pisses me off that there's no serviceable filter. But giving up a V8 in a fairly-rare car to go backwards into ordinary? Re-think this.

Haha sorry, I ended getting busy halfway through posting that so I summed it up quick and sent it
