Just picked up an 02 LS, searching I have heard rumors of problems with the first year. What are they and what should I look out for. Oh yeah it has 39K on it.
Thanks

one of the problems I remember was that the cylinder sleeves were prone to failure. I think early in the engines life. if past 30K I think, youd be ok.
This was fixed for later model yrs.
Also when they were 1st introduced, they were recalled because of some bad suspension part that could cause vehicle to lose control or something. but these were actually picked up by tow truck and fixed.

Man I hope "ALL" of them were picked up! Well so far I love the vehicle as far as ride fit and finish.

Has the dealer replaced the circuit boards yet? (The part the bulb attaches to)

my engine blew at 22,000 miles...was replaced by a brand new one...warranty on 02 go up to 100,000 miles as far as I know because of all the "broken" engine problems

BlazinTBlazer...GM had its' share of "teething" problems with the '02 T/Bs (first year introduction). Engine condition was there and a higher than normal amount of recalls have come about since its' inception. It also has its' own, shall we call them..deficiencies, just like any other model, brand or manufacturer. All the deficiencies I'm aware of are fixable. Good Luck with your "02...should you have any condition arise, please post or message me...I'll be glad to help where I can.

I have a deficient engine (4.2L I-6) in my Envoy. Who can put a V8 in and get it to work properly with all the electronics (PCM, BCM, etc. etc.)?

LOL... good stuff. When I first got my truck and didn't know it had already gotten a new engine, I said "If and when this engine blows, I WILL find a dealer willing to stuff a 5.3 or larger in here!"

Hey guys: I think the most feasible way is purchasing a totalled EXT, XL, etc. w a 5.3. The electronics and drivetrain parts are all bolt-ins. You would need a shortened driveshaft. I know that a competent driveshaft facility can fabricate a driveshaft based on your specifications or those of a SWB Rainer. You may need the assistance of someone with a GM Tech II and GM access as data from the 5.3 vehicle may need to be tranferred into the recepient vehicle. You can "part out" unneeded components from the donor vehicle for extra "project money" or beer. GM did it with the Rainer...why can't anyone else???

You make a good point -- but wouldn't the driveshaft be the same as with the 4.2, or is the positioning a bit different? I'm thinking at least everything from the trans. back wouldn't need to change, right?

I have been told that the wiring harnesses would also have to be changed to that of the V8.
This "transplant" seems frought with all sorts of landmines, and could turn in to a real money pit.

I'm only suspectant in the driveshaft matter, but I know the V-8 rear axle is larger is size for durability issues. I know the V-8 can administer more punishment than an I-6 can and I believe the factory accommodates for this in the driveline department. I know the axle flanges are different and suspectant that the V-8 flange is larger. An I-6 driveshaft would be of the same length, but I foresee a component mis-match @ the axle flange. But as said again, in the hands of a competent driveshaft person, the EXT driveshaft could cut down & re-welded to the required SWB length. .

I didn't mean my previous post (#11) to sound like a "walk in the park". My response was directed to power output solutions and a desire for V-8 power with your existing vehicle. At this point, I do not see any I-6 performance add-ons that net noticeable results. I concur with those that a mine detector would be required, but show me a transplant of this magnitude that wouldn't. If we were to ponder this, you could also look at the cost of a totalled V-8 EXT and the trade-in value of your vehicle. Do the math... maybe you could just buy a V-8 EXT, transfer the plates and see ya".

However there are some people (myself included) who wouldn't be able to have an EXT/XL. The SWB is the only thing that will fit in my garage! I honestly almost had a 2000 Yukon until I took it home on a test drive only to find it was too long AND too wide for my garage. The EXT is no shorter than that and wouldn't have worked.
And granted, I could buy a ranier, but I don't see any in my price range with the V8 in them. I'm happy with my Envoy with the exception of the powerplant's lack of V8.
I'm sure there are plenty of differences. The chassis shouldn't be a problem for a swap, the replaceable parts might cause a problem. I'm sure someone willing would be able to do it. Most of the parts would come from the donor vehicle. You might have to have a custom exhaust. On the Grand Prix site they had someone stuff a LS1 5.7 L V-8 into the engine bay where a 3.8 V-6 usually fits.
About the original question, the 2002s problems. I can recall a lot of people having electric problems with the transfer case.

I understand the size issue. I have a typically-sized two car garage. Backed in, with the front bumper inches away from the back of the overhead door, I have to step/walk sideways between the back of my T/B EXT and the back of the garage to get to the garage service door. I have approximately 2" of "junk" behind my T/B, but I can agree with EnvoyGuy about garage space. And yes, 2002 transfer case issues were a total nightmare. Sure wish Whipple would consider the I-6 powerplant and create a forced induction power solution...

Definitely I agree with this. A whipple supercharger would definitely on my mods list.
As for the T/C issues, my truck has had the shift solenoid replaced once, and the switch on the dash replaced twice. I don't understand the deal with the switch -- if the '03+ aren't having as much issues, why would these in the '02 keep failing?
(Though I will note that before I got my 'voy, I was in a family friend's '04 Envoy and saw it do the exact same thing my truck was doing when it was broken)
