I know of several that replaced the clutch without the PCM update and all is well. That update made almost a year before the new type clutch came out so it is not specific to the new clutch design. The manufacturer of the clutch (Behr) says it is backward compatible and reprogramming is not necessary. (GM dealer will probably tell you it is absolutely necessary and you must do it.) I replaced the clutch myself in my garage in a little over an hour, so I would think an independent shop should be able to do it. I would want someone to do it that has done this job before because there are a few details to know that will make it easier. Good luck!

i replaced my stock fan/clutch with twin 14" electric fans.
cost $120. The OEM fan clutch has gone out twice on my 2002 bravada. No more!
Also---mine has an odd noise coming from the front of the vehicle. It sounds like a rubbing noise and a grinding noise combined? any ideas? it does it when going fairly slow--sometimes straight, sometimes when turning.
It doesnt always do this---just out of the blue it will.
Never on the highway---just in town.

Spike,
 
I'm glad that you got some use out of my 50k mile post. Just a few notes on the 3rd seat of the Envoy. They work well for short hauls, but you wouldn't want to sit back there for more than an hour or so. I have had some complaints from my passengers in the rear that since they were sitting up higher than the rest of the vehicle, it is difficult to see out of the windows. Access to the third row seat is okay, but it requires tilting one of the middle row seats out of the way. In general, I would say that it is nice for infrequent use, but not for everyday travel.
 
With all of the seats folded down, the storage is pretty good but plan on hooking up your trailer if your are picking up anything the size of a sheet of plywood or larger.
 
Keep us posted on your final vehicle selection (I may be looking soon myself).

03 Envoy clutch replaced by kevitra

Our 03 Envoy was sluggish and loud as a jet so we had the clutch replaced under our extended warranty.
 
Every morning when the truck is cold the fan runs at 100% for about a minute. The service center has told me twice that it is "normal" for the new part. How is this normal? Is this what every one else's does after having it replaced or is something still wrong with ours?
 
The clutch is the only issue we have had with the truck in 5 years and 60K miles. We like the truck a lot but the loud van makes it sound like a POS. It also still isn't running like it was a year ago but all I heard from the shop is "it is fine."
 
Thanks

Thanks for your feedback and others who recommend good and bad items of the Envoy XL I6 2wd vehicle. We won't be trading in our current "used" 2003 Safari until its paid off - which is in another 2 years. (so sad because I don't like this old technology "lemon" anymore).
 
At this point in time, I'm only doing "early" preliminary RAW Data research. And if wondering, we will be replacing our van with an Envoy XL "like" vehicle. Luckily, our focus is on "up to 5,500 lbs" of towing power (for utility trailer pulling) and "long haul" vehicle for family trips. We have a much smaller cross-over FWD vehicle for our daily commute vehicle. If possible, I would like the remove one of its 3rd row seats and thus, having 2+2+1 comfortable seating. And, making extra storage in the rear (by removing one of its 3rd row seats). Not too sure if one seat in the 3rd row seat can be removed. Hopefully, it can.
 
In the end, the buying power of which "used" vehicle we buy is under my wife's control. I can do all the RAW research in the world but if she doesn't like the way the Envoy XL (or its competition design vehcile) feels on the road, she walks away from it. Since we switch driving positions on long haul trips, the final buying power is really hers. Although, having both good and bad "patterns" of the 2005/2006 vehicles is good "influence" ammunition as well. Especially for high "bad" pattern areas on specific models.
 
Thanks for allowing me to perform early base research - on the Envoy XL "like" design vehicles.

On the Envoy XL the 3rd row is 50/50 fold down. You would only get a little more storage space if you got the tools out and removed one side. Also, when folded down for cargo instead of seating, the floor is pretty much flat...I would have to look tonight since the wife drives the Envoy, but if you removed the rear seat, I don't think the cargo floor would be anywhere near flat.
 
Seat bottom is hinged...raise it up a little and pull forward, then the seatback folds forward and you are ready for cargo with 2, 2, 1 seating...do that again and you have 2, 2 (3 in a pinch) seating. Rear is only good for 2 wide...3 adults will fit in the second row for a maximum seating on 7, 6 is much more comfortable though.

Oil from two rubber plugs near torque converter by bobed2121

2002 TB LTZ 4x4 115,000 miles
We took a trip over the grapevine (between Bakersfield and Los Angeles) 2 weeks ago. The transmission did quite a bit of shifting as expected climbing the hills. When we got back home I noticed oil spots under the TB. I went under the car but the oil was pretty much all over the place probably from the drive and wind pushing it all around. I noticed that the 4x4 switch was set at AWD 4x4 and not on 2wd as it should have been. The oil was not coming from the engine but from the transmission I expect. I washed it off and checked it the other day but didn't see any new leaks. There are two small rubber type plugs that are on the very bottom of what I believe to be the torque converter housing. As far as I can tell the oil may have came from the left side plug. Anyone know what those plugs are for? I can spin them but have not yet tried to pull them out.

Is it oil or transmission fluid? Did you check to see if any of the fluid levels are low?

noises by carriegrubbs

My 04 envoy makes a noise from the rear that makes it sound like a powers wheels. Its a constant whirring noise that get louder when you apply the gas and quieter when you take you foot off. I don't know if the noise is becoming more prominent or if it is just annoying me so I hear it more. Is this common or has anyone done a fix for this?

Transmission level was slightly low and I'm pretty sure that somehow the drive climbing the grapevine doing 75mph and the transmission shifting from D to possibly as low as 2nd at times caused some sort of "blowbuy" that forced fluid out somewhere. The thing is now on normal driving conditions there is no leaks what-so-ever. I can't figure out where it may have come from and why it is not leaking now??
