Tip & How-To about GMC Sierra 1500HD

CHECK ENGINE LIGHT ON, TRANSMISSION NOT WORKING RIGHT

WE ALL CAN AGREE THAT TODAY'S TRANSMISSIONS ARE GETTING MORE COMPLICATED. THEY ARE ALSO GETTING MORE CHALLENGING TO DIAGNOSE AND EVEN TO REPAIR. BUT WITH THE SOPHISTICATED TCM (TRANSMISSION CONTROL MODULE) OR PCM (POWER CONTROL MODULE) THE INFORMATION IS RIGHT AT HAND. THE CHECK ENGINE LIGHT IS WARNING OF A ISSUE, NOT ONLY THE ENGINE, BUT THE TRANSMISSION AS WELL. TO CATCH THE PROBLEM AT THE FIRST SIGNS, THIS IS THE KEY, ESPECIALLY WITH THE TRANSMISSION, IT DOESN'T TAKE MUCH TO TURN A SIMPLE FIX INTO A LARGE REBUILD BILL. BE MINDFUL OF YOUR CARS ABILITY TO TELL YOU THAT SOMETHING IS WRONG WITH THIS LIGHT.

how do i changege spark plugs in my 2002 kia sportage 2.0 liter dohc


Changing the spark plugs in the DOHC is such a pain. I've done it on a couple Kias. I strongly suggest you get a Chilton/Haynes repair manual that covers your year/make/model This book will lead you through the process under "Tune-up/Maintenance." It also has troubleshooting, interior repair and upkeep, etc. It even leads you through complete motor rebuild. Transmissions they say to leave to the professionals, which I wholeheartedly agree.

You have a failed transmission, the most likely source of the noise is the transmissions front hydraulic pressure pump. Most transmission repair shops will diagnose this for free and let you know the approximate cost to repair. This doesn't apply to the BMW dealer service dept.

transmission won't shift out of 1st gear


You will have to check the valve assembly- the part in your transmission that controls the gear shifting. In this model of transmission it's purely hydraulic so most likely one of the pressure release valves is stuck.
This is an very complex job that must be done only by an experienced mechanic. So either locate a repair shop specialized in transmissions or replace the entire transmission with a good second-hand one.

I have a 2002 Audi A6 2.4 V6 Multitronic. The problem with it is that the gears do not engage. Should I buy a new gearbox or have this one fixed?


Im assuming you have an automatic, first check that the fluid level isn't low. Other than that there's not much else you can do yourself. Automatic transmissions are extremely complicated, and require special tools and knowledge to diagnose and repair. Your transmission may only need a relatively simple repair so don't just go out and buy one. Take the car to a reputable transmission shop, or a repair shop that services automatic transmissions. If they determine your entire transmission is bad, it is almost always cheaper to purchase a rebuilt transmission than to have your transmission rebuilt.

I have a '97 DeVille and the reverse gear is not working. The shifter goes into gear, but when you give it gas, nothing happens. All the forward drive gears work great. Any idea what is happening and what the cost to repair would be?


Automatic transmissions are very complicated pieces of machinery. The only thing you can really do yourself is check the transmission fluid level. If the level is correct have the car looked at by a reputable shop that does transmission work or a transmission specialist. As for repair prices, it depends on what's wrong. It could me a simple mechanical problem that can be fixed without even removing the transmission, or the transmission may need to be rebuilt/replaced. Expect to pay as little as a couple hundred dollars for s repair or up go several thousand on rebuilding/replacing the transmission. I hope it's something simple. Good luck.
