I haven't, maybe it's something that GM had plans for but never pursued. You know owner's manual are very universal.
Thinking about owner’s manual, don’t think i ever opened one for any of my vehicle lol.

My owners manual talks about express up windows and how to reset/program them after a battery disconnect, but I haven't seen/heard of one with that available

I'm wondering if it's just laziness on GM's part, that they used the same manual verbiage as for the GMC/Cadillac trucks. At one point in the manual it says, "all 6.2L all wheel drive 1500 series luxury model applications," and "all 6.2L non‐all wheel drive 1500 series luxury model applications." Pages 6-52 and 6-53 of the 2010 manual.

Sounds like the Denalis or Escalades to me.

I have heard of L76 Suburban's and Avalanche's, up until 2010. Early ones had the 4L65, and 09-10 had 6L80. After 2010, the L76 option was discontinued.

I've seen some 2500 Avalanches with the 8.1L. Hoss drivetrain, but ugly AF.

All my literature shows the L76 paired with the 4L70 (M70) except for 2009 when it was mated with one of the 6-speeds.

As I understand, that motor is widely hated and renown as being a big piece of garbage. I dont think they were very reliable, and thus not very popular.

Uh, blasphemy! Those are great motors but they are not high rpm race motors, they are low rpm torque monsters designed to work, not race. Still in production.

They were widely used in 1500 series trucks in the 1980s (square body and 6.2 motor) and 1990s (GMT400).

Is it the same diesel they put in the burbs of the era? I had it on good authority from a true chevy guy that he wouldnt own one of those if his life depended on it. And he's got a dmax, so he's got a good one to boot.

Yes, they were several versions in natural and turbo-charged configurations. Those motors are not Duramaxes and don't run anything like them. But operated within the profile in which they were designed they are great engines. I drove the gran-daddy of those, an old D-Block 350 diesel in my Oldsmobile for years and it was one of my favorite engines. Wish I still had it.

I didnt mean to imply that the old diesel was the dmax, just that he had experience in the GM truck diesels.

The olds was also a hot piece of garbage from what I've seen over time. But that was more related to user error and not following proper maintenance.

If you like youtube, check out car wizard. He's putting an olds diesel in a late 60s caddy brougham. 0-60 in 30 seconds, but I bet it would be smooth as hell.

My Cutlass ran 21.63 @ 63 MPH in the 1/4 mile all night long, every pass. Great bracket car! And I used to deliver pizzas in it when my Buick was down for repairs.

Yep, people hated the Olds diesel too but it was great to us. I didn't try to spin the motor to redline every day, even while racing, and kept the fluids and air filter clean.

Yeah I guess they (the populous) just didnt know how to treat it like a diesel since it wasn't very common. Funny you mention this I just recently watched the motorweek retro review on the Olds 98 Diesel. What a boat. But it also adds new indicator lights that the common folk didnt know how to manage like the WAIT FOR START, and WATER IN FUEL....both bad things for a diesel if you dont resepct and understand them.

That "wait light" later came in handy for letting fuel pumps prime and still later, letting the computers boot and synch up before starting the engine.

My wife would have all kinds of electrical gremlins but I never did. When I asked if she followed my advice to wait a couple of seconds before starting the car she said no. Eventually she listened and the problems went away!

I loved my 98 Regency! We had an '80 Delta 88 with the Rocket 350 too.
