Chevy Suburban Only Has 1st Gear
I have a 2005 Chevrolet Suburban 1500 LT. It is a 2wd truck. Yesterday when i was going to work, the engine light warning lights up and then the transmission will only shift in park, reverse, neutral and first gear. The owners manual says that the light is for possible ignition problems or fuel system problems. What is wrong with my truck?
Can you please tell me exactly what your transmission is doing in your truck? Does it not shift into second, third or forth gears? What else does it do?
Reverse gear works fine. The truck moves forward just fine, but It will not shift out of 1st gear to go up to any other gear.

Answer:
There are a few different possibilities of what could be wrong. The service engine light is the first
thing to look at to start diagnosis. There may be transmission codes stored.
The check engine light may come on for many different reasons. The codes stored could be related to the engine emissions, ignition, or fuel systems. But it can also come on for transmission problems.
Some engine related codes will cause the transmission to default to this kind of shifting patterns. But most of the time the transmission is the problem and will cause the SES light to come on. You need to get the codes scanned in the computer and find out if the light is on for an engine or transmission problem. Many different transmission problems can cause the light and this shifting problems. There are a few service bulletins depending on the codes stored. Your truck could have a problem in the ignition switch, internal transmission components like a reactions sun shells, forward locking sprag, servos or shift solenoids. Solenoids are most common.
OK. Thanks you. How much it will cost to get the PCM codes scanned? Should I get it from my Chevrolet dealer or take it to Autozone to have them do it for free?
You might want to get the codes scanned for free first. It may be that a simple engine related control sensor is bad causing your transmission problems. It may even be something that you can fix yourself. A local mechanics repair shop is much less labor rate than at the new car dealer.
Another thing you can do is to check all of the fuses. Just to be sure it is not just a blown fuse. If there was you would have to locate the cause of the short circuit and blown fuse diagnosed. that may get your truck driving normal again until you can get it repaired.
Question:
Am attempting to replace the upper actuator on the HVAC module. Need to remove
I/P carrier. Have most of the carrier off, but need to remove the handle on the passenger side,
which appears to be press-fit into plastic tubes held in place on the carrier. 2000 Chevrolet Suburban 5.3l V8.
Is there a trick to removing this part? I have instructions for doing this job on a 2004 Suburban but Mitchell does not have info on this (it says "remove IP carrier" and leaves it at that). I have all connectors out of the way, the airbag module is pulled, the IPC is out, all airflow ducts are disconnected, the steering column is lowered (but not removed), the center console is out. Any suggestions or assistance would be amazing. Thanks in advance!
Answer:
The handle in the dash on the passenger side is not pressed in. Can be a little tricky to remove.
Remove the HVAC vents on either side of it. Each handle has a release tab accessed though the
opening of the vents when removed. Press the tab on one side while pulling out just a little, then
while holding that side, press the tab on the other side and pull that side out a little.
Then pull both sides equally. Can be a little tight. The handle has rods attached to each end a few inches long. Pressing the tabs releases the rods from the dash- similar to removing a headrest.
