My 04 Aveo is slipping sometimes, usually when going uphill.

My 04 Aveo is slipping sometimes, usually when going uphill. Should I have the filter and fluid changed or expect to have to replace the whole transmission soon?JA: How many miles are on the car? How has your mileage been lately?Customer: Almost 170k. My mpg is normal, about 30JA: Are you hoping to fix this yourself? What have you tried so far?Customer: Not myself, no but I don't want to be cheated. It just started in the last week or so. And it's not a constant issue yet.

I wish I knew. WHen I first start in in the morning, it will

I wish I knew. WHen I first start in in the morning, it will run well for about an hour or so. Highway, in town, all of it. Then I go into a store for 15 minutes and it barely starts, operates in a limp home mode, pinging all the way! I have a new distributor, coil and plug wires installed. Recently added new spark plug wires. I am having new knock sensors put on Monday. But I'm not sure I'm making any progress. The car was running well until a couple of months ago, when it died on me. That's when I replaced the distributor. I just don't know what do to.JA: Which particular sensor are you asking about? And have any trouble codes been triggered?Customer: The knock sensors…or sensor low on the passenger side of the engine block.JA: What is the model of your '15 Chevy?Customer: 1987 Corvette.JA: Are you hoping to fix this yourself? What have you tried so far?Customer: I was hoping to. But I don't have a lot of equipment and frankly have got too old to be sliding around under a car like I used to.JA: Anything else you think the mechanic should know?Customer: Well after the car limps home and I turn it off, there is some smoke and a burning smell that comes from the distributor. I've thought it was perhaps from oil or that came wirth installation of the new distriibutor.

My 2000 GMC Yukon wont start. Thought it was a bad fuel pump

My 2000 GMC Yukon wont start. Thought it was a bad fuel pump after checking fuel pressure. No fuel pressure. Changed fuel pump ,and still no fuel pressure. Fuel pump relays are good and power at the ECM fuses. This truck has a new pigtail attached where it plugs into the new fuel pump but I did not check for power at the plug end before lifting the tank back into place. Probably have to drop the tank again and work my way back. Suggestions?JA: Has your car been stalling?Customer: No. just one day wouildnt start.JA: Are you fixing your Yukon yourself? What have you tried so far?Customer: Above I typed what I have done.JA: Anything else you want the mechanic to know before I connect you?Customer: No

Need help on a 2002 Chevy Silverado HD 2500, with Duramax

Hi, need help on a 2002 Chevy Silverado HD 2500, with Duramax diesel engine, and Allison automatic transmission. The truck is experiencing a "shifting" problem. The following DTCs were pulled: P0841, P0872, and P0873. I have not driven the truck yet, but customer states chart does not shift above third gear at times. Also states that if they pull off the side of the road put the truck in park turn off and then restart it and take off it will shift normally again (until the next episode) only seems to happen approximately once a week with normal driving. Is the pressure switch solenoid "C" possibly the culprit or is it controlled by something else? The truck has 592,000 miles on it, it is owned by the original owner, and I have known the truck its entire life. The transmission is original other than fluid and filter changes.Thank you in advance, Richard.

It was loosing fluid, and lost reverse, and second gear

it was loosing fluid, and lost reverse, and second gear would not shift up, topped fluid level back up, which was leaking from a seal to the cooler, but still no reverse on my chevy 2002 trailblazer LTZJA: What is the color and consistency of the fluid? And where exactly are you finding it?Customer: brown color, and leaking at the frontJA: Are you hoping to fix this yourself? What have you tried so far?Customer: I am an engineer, but gear boxes are not my thing, but have had my mechanic look at it, but he is not a gear box man, would like to know if its something simple before I let a dealer look at itJA: Anything else you think the mechanic should know?Customer: it was driving ok, stopped for gas, and noticed a small amount of oil when I came back to the car, then I had no reverse, and had to lift to get it to change up from 2nd to 3rd, probably lost about half a ltr of oil, that has been topped up, but now still the same

I have a new 2016 Chevy Suburban LTZ. When using the remote

I have a new 2016 Chevy Suburban LTZ. When using the remote vehicle start, the rear A/C doesn't blow from the overhead vents. It just seems to blow in the back from below somewhere. I have a 2007 & 2011 Tahoe LTZ and when using remote vehicle start, the rear A/C turns on high and blows from the overhead vents, cooling the car nicely. I have my car at the Chevy service center and they are saying that the Suburban isn't designed to turn on the overhead A/C units in the back. I find that very odd since it's not what I have experienced with my Tahoes. I often load my kids in the car while loading groceries, etc and use the remote auto start to cool the vehicle. I don't want to put my key in the ignition for safety reasons if I'm not in the front seat. Is the service center correct when they say it's designed for the A/C not to flow from the overhead vents in the backseat of my suburban? The front A/C vents blow at high with no issue.
