Found it documented. Was in my GM Service Info as a TSB-
This is in my GM 2002 service info. I think the same would work on a 2004.
Document ID # 793757
Tech 2 Information on 4L60-E Shift Adapts (Clearing Shift Adapts)
#01-07-30-018 Issued 04-18-2001
2002 Chevrolet Trailblazer
2002 GMC Envoy
2002 Oldsmobile Bravada
with 4L60-E Automatic Transmission (RPO M30)
and 4.2 L Engine (VIN S -- RPO LL8)
The above listed vehicles have PCM software that does not allow the Tech 2 to display or clear shift adapts. Even though the shift adapts will not display, they will function as expected. Since the shift adapts modify line pressure, it is required to clear them during a significant transmission repair.
If the adapts are not cleared, the customer may comment on either soft or harsh shifts after a major repair.
To clear the shift adapts, it is necessary to disconnect power to the Powertrain Control Module (PCM) for 35 minutes. Refer to the Powertrain Control Module (PCM) Replacement procedure in the Service Information.

Had the very same issue but 3X the trouble with the front and rear bumper bars failing as well.
I took everything off this spring and took to the local paint shop for a blast and repaint. Everything back on now and I'm a happy camper with $200 less in my pocket.
When the tail light cages were painted the bodyshop removed the lens tape anchors. The nice folks at WAAG mailed me 4 replacements for free.
I did write them to tell them about the "indestructible" powder coat that is not!!
They thanked me for the feedback and supplied the parts.

It depends. I like the idea of a 6.0L in the SS. If you can stiffen the ride of Z71 and include the 5.3L, then you have a winner in my book. I used to own a 1996 Jeep Grand Cherokee with the 5.2L with the High Country suspension package. It gave the vehicle a one inch lift from stock and offered a stiffer ride around town, but I knew I would not be replacing the suspension. I kid you not, when I get rid of that vehicle at 130K miles, the suspension components were still tight as the day I drove off the lot. The current stock suspension on my 2002 TB is too spongy- however, I have gotten used to it. I personally like a more active suspension even it delivers a less smooth ride around town. If it was not for a $3,000 electrical problem/malfunction with the JGC, I would be still driving that vehicle today, but that was the last of Chryser in my books. However, I would not buy a Z71 Trailblazer if it did not have come with the 5.3L. Don't get me wrong, the 4.2 is a good engine, but it needs to have stronger torque.

twinrotts - The moral to this story is don't believe everything you read -- especially if it is on the internet. What you hearing is what is also known as "the Italian tune-up" -- useful on Alfas and Ferraris and such that have been lugged around in city traffic -- usually in high gear! There really is no need for such measures with most modern engines -- especially engines that lean more toward the draft horse than thoroughbred side. Still, I think it does no harm to give it a little work out on occasion. It blows out the pipes and may help seat the rings if done just after break-in (not keep them free of carbon). It should also put a smile on your face.

It's an inline 6. Usually these aren't real torquey on the low end. Try it in a BMW and you'll see the same thing. The V-6 in my '93 Blazer was another story. Easy to wear out the tires in that one!

Just got back from a 2200 mile trip with my '03 Envoy. Good news, 21 mpg for the trip. Bad news, I spent 2 hours the first night in the Motel parking lot trying to fix the brake lights. They would NOT turn off. This is the second time. I guess the dealer didn't fix it the first time. Also, when I got home, I noticed rust and peeling paint on the inside of the rear doors. Arrrggghhh! This just is NOT right! Can GM really be this bad????
#16578 of 18329 It gets worse
May 09, 2005 (6:29 pm)
This is so funny I could.............
The cruise on my Envoy didn't work on the way home. Come to find out the brake lights are stuck on again and won't let the cruise work. Drive it right to the dealer. They have no brake light switch in stock and want to talk to tech services as this is the 2nd time this has happened. They arrange for a loaner. The rental company comes to pick up someone else but forgets me. Finally, they come back and get me. I get to the rental car company where they tell me they can only give me a GM vehicle as that is all GM will pay for. They are out of GM vehicles except for a 1 ton Chevy cargo van. Guess what I get, a flower delivery vehicle. Guess who's vehicle shopping this upcoming weekend.............enough is enough.

Sorry to hear your troubles. Is is the same thing as the brake light circuit recall GM did a while ago on the triplets? Or is it a seperate item? The rental car needs to be comprable to what you are driving and this is not acceptable in my book. The dealer needs to compensate you with some measure. Dealer needs to have rental backup plans when their rental agency cannot accomodate its customers. I do not buy that rental car agency bull that they can only put you in a GM!!!!. Twice in the three years of owning my TB, I have driven a Ford F-150 quad cab and a Tahoe as rentals. Guess what, the dealer pays Enterprise and it does not matter. The more I read your post, the more angry I get!!! Turn up the volume and start making some noise.

I've already had the tail lamp recall done. This is the switch on the pedal itself.
It get's so hot from being on all the time I'm surprised it doesn't start a fire.
This whole situation is extremely frustrating. GM replaced my Bravada with the Envoy because of numerous problems and this one isn't much better. I expect more from a $38K vehicle. No complaints with the dealer. They have been good to work with. I'm jealous of all you out there with good ones!
#16581 of 18329 channeling anger and jealousy
May 10, 2005 (9:35 am)
gam2, Greg, channel that anger energy and drive directly to any dealer other than a GM dealer. GM will eventually feel the anger. I did just that and have been much calmer for 2 months now. My Mitsu. 05' Endeavor has been everything I expected the TB to be and better at that, and I still don't know my Mitsu. dealer mechanics by name.
