Question about 2003 GMC Envoy

1 Answer

My 2003 gmc envoy makes a low humming sound almost like the 4 wheel drive is always engaged

Sounds like a transmission problem but the transmission isn't shifting badly, doesn't matter 2 wheel or four wheel, some vibration, no steering problem there does seem to be some drag sound continues in neutral while moving

I recently took my vehicle to a transmission shop and they had to rebuilt the transmission right through. I was recently told that the transmission is a common problem in these vehicles. Sad that GM can not fix or recall the transmisison since there is a problem.

SOURCE: I have a 2003 GMC Envoy, trans slipping that I have been towing

Low fluid can cause slipping. (depends upon how low) Most manufacturers post "safe" tow speeds. These are generally ignored. (not good). I recommend towing with driveshafts removed and where driveshaft has a "slip yoke" you install a yoke from a scrapyard and wire it to the tailshaft so it stays in place (keeps oil in and dirt out) Although you can't just detach the tow-bar and drive, it eliminates any possibility of trans damage, since the transmission cannot turn. (most use oil from pump to keep gearsets cool...when towing, pump is not pumping and over time and distance it can damage trans internals.)
Hope your problem is just low fluid and not a rebuild...keep in mind what I said though.

SOURCE: wont shift back from 4x4 low, to 2x2

I also have a 2002 Envoy. Shifting to and from 4wh and 4wa can be done on the fly but shifting to 4wL has to be done stoped and while in neutral. Try that. Otherwise I'm afraid its a new computer for you. Its located under the left rear seat and you need a loan for one.

the auto 4 wheel does the same as part time in jeeps, it engages only when the vehicle loses traction. when auto 4 wheel is on the truck isn't fully in 4 wheel drive. my 02 sierra makes the clunk noise too but it does engage. try checking your fluids, i know its way pass the time for me to change mine out.

A transmission problem would not make the steering wheel vibrate. Have you ever had the Transfer Case fluid changed? This is required every 50K miles. A qualified transmission technician should evaluate your problem.

Around 1500 rpms or 55 mph engine seems to bog down


It sounds like your low on fluid, or your transmission filter is dirty and the front pump is not getting enough oil supply. Worst is your front pump is going bad. 
Check the fluid level and see if it's burnt. Good luck

2000 GMC Jimmy Transmission Whine


Does it sound like a loud winding sound coming from the front right side? I have a 2001 Jimmy and the 4wd tries to engage when driving up steep hills and going at highway speeds. The actuator vacuum switch engaged when the transfer case vacuum switch sends the vacuumed air to the actuator. What is happening is their is either a leak in the vacuum lines, a faulty actuator switch, or a faulty transfer case vacuum switch. When the jimmy has enough air pulling in, the extra vacuum is trying to push the actuator switch in when it is not supposed to. It is a much cheaper fix than a transmission. GMC should have recalled the whole 4wd system on any of the S10's, the JImmy's, and Blazers.
