YEP YOU NEED VSS SENSOR HOOKED UP SO TRANSMISSION CAN SHIFT RIGHT.AND SHIFT TO OVER DRIVE AT SET SPEED. YES YOU NEED TO SEE YOUR SPEED TO KEEP FROM GETTING A SPEED TICKET.DONT UNPLUG IT.

Inside your automatic transmission is a cawl that engages a notched ring. If your transmission linkage has become bent for some reason, or the transmission has been moved (an accident, a damaged mount, etc.) then it might take some extra persuasion to get into park. Internal damage to the transmission is also plausible if the trans was abused in some way. That could include putting stress on the park mechanism, even as little as parking on a steep hill and relying on the transmission cawl instead of the parking brake. The vehicle needs to be put up on a lift to check for obvious linkage problems--otherwise it gets more serious.

The 04 SIERRA is behind a panel with 4 screws under the glove box...Remove the screws and cover and slide it out.There is actually 2 in there and it is easy once the cover is off.

Usually there are extremely detailed instructions that come with the new filter when you open the box...Follow these instructions it shouldn't be too hard.

Pretty much...had a 2006 Chev 2500HD Crew Cab 4X4 w/6.0; got 12mpg regularly...which is why it's someone else's truck now. Have a 03 1500 GMC 5.3 Ext Cab now; get 18-21 mpg. Sweet!

This is a well known issue with model years 2003 thru 2005. There is a chance GM will replace it under recall... Call the Chevy Customer Assistance Center 1-800-630-2438 to find out.

If not and you want it fixed, try Southern Electronics at http://www.instrumentclusters.com/.

Give a check on your ball joints. If you jack up the truck where the front wheels are off the ground, put your hands on either side of the tire and try to move it, if it moves up/down, your ball joints are bad, if it moves side/side, your tie rod ends are bad.

AUTO DASH SAYS 'REDUCED ENGINE POWER" TRANSMISSION FLUID SEEMS OK AND COOLANT OK. WHAT ELSE COULD IT BE?

Is this after recent oil change.Sound like you have the wrong viscosity of oil.
