I have a 2004 envoy which wont move when put into gear. Is this a lockdown mode and how to fix it?

if their is a check engine light have the code read ------no such thing as lock down mode you have limp mode which will let you limp vehicle home or to a shop or off road safely sounds like a transmission problem check fluid --look and smell if it looks burnt brownish and or smells burnt try a flush with a fluid and filter change may gey lucky ---look under vehicle and check the selector cable and connections sometimes disconnect or rot away lastely possible internal problem which would need a transmission specialist to look at

Fouled camshaft sensor

You must take it to someone who has the ability to access the OBD2 codes for the transmission. Your transmission may or may not have to be pulled as some codes can be repaired by replacing sensors or solenoids.

Transmission slipping on 03 GMC Envoy. what does iy mean when trans fluid measure high on dip stick?

Two things: #1 someone has overfilled it by mistake thinking they were putting oil in the engine. Yes I have seen this.
#2 The transmission cooler in the radiator could be leaking antifreeze into the transmission through the cooling line raising the fluid level. I would look for milk shake foam on the dip stick and make sure you check trans in park and not neutral.

We have 5 codes, po141,po172,po606,po014,po016 on a 2004 gmc envoy xuv. Can you help.

Here is a brief description of the codes;
P0141 - rear O2 sensor
P0172 - system too rich
P0606 - PCM internal failure
P0014 - Camshaft phasing off
P0016 - Camshaft position and crankshaft position off

This going to require a qualified technician to diagnose. The PCM issue may require a reflash of its memory or a replacement.
The other codes could be related to each other. One suspect item is the camshaft position actuator, sometimes it gets clogged with oil and make it fail.

Fan clutch and coolant flush

If there is another dealer nearby get a second opinion. Repairs these days are very expensive.

02 envoy

Just like when you have a loss of 4x4 drives, it is a drive sensor and elevator problem. It seems like everyone of the major types of fixes like this are 600.00 at the dearlership,, takes about 2 or 3 hours,, but vehicle will run like new afterward. I dont think this is a do it yourself type of a project.
