2000 silverado will not go into gear by dkelley85

I have a 2000 silverado. I was driving it the other day, then a loud sound came from under the truck, now I can put the truck into any gear, but it will only move in reverse. I can put in into drive, 1st, 2nd and 3rd, nothing happens. When I put it into PARK, it acts normal, the truck will not roll. Any suggestions!?

Sorry to have to tell you, but I'm pretty sure you dropped (blew) your tranny. I had a truck years ago that did the same thing. Same problem, all I had was reverse, no forward gears. Park won't have anything to do with the gears. Just the parking paul dropping in to secure the vehicle. How many miles?

Since 1999 and good old G.M. hasn't fixed the problem and they want the tax payers to bail them out. I am so glad this has happen to the big so called 3 and hope it will change the automotive world for ever. Sorry for the ones who lose their jobs and I have family that will be part of it, but they agree also that it has to change with the unions and management. They have held the average person hostage for decades and didn't give a dam about it.

bump at 1st shift 2006 sierra by b36

I posted before about my 2006 5.3 V8 sierra giving a bump when starting out slow..the bump occurs at around 15mph at the first shift. It does not do it if you can take a little faster. I took in to the dealer and they said there couldn't be any thing serious wrong or I would get a warning light. However they did re-program the transmission because of a service bulliten. It did nothing for the bump. A transimission shop says they thought it was the coolant pump hanging up. The service manager said if that was happening I would get a light. I have 6 months left on the warranty. does anyone have any ideas? Does any of this make sense? thanks

My 04 silverado does the same thing but only after it warms up .if i take off fast it does not do it. its been doing it for a long time.it now has 112.000 miles .i figure if i take it to a tranny shop they will tell me i need a new tranny .so i just leave it alone and have regular service fluid flushed.other then that bump from first to second its fine

Hey Joe in regards to your 04 Silverado.
 
If your truck has a lot of hard tow miles it could be in need of some internal parts. If it's just 112k everyday miles then it could just be the 1-2 shift servo. The servo's are on the outside (side) of the 4L60e in your truck (assuming it's a 1500). It's an inexpensive quick fix also. The Hydro-Matic (GM) transmission is one of the best out there. BMW even uses the Hydro-Matic automatic trans. in their 5 Series cars. It's a very solid well built transmission. Don't listen to the GM haters out there.

If there aren't many hard tow miles it might not have been properly serviced by the guy or guys before you. This is the reason General Motors now uses Dextron VI ATF, 100k before first service, verses 30k for the Dextron III or IV that your truck uses. The Hydra-Matic auto trans. is one of the best built out there. BMW also uses the GM Hydra-Matic (a 5 speed auto exclusive to BMW) in their 5 Series premium cars.
I've always driven a Chevrolet from an '86 Chevy 3/4 ton 4x4,'96 Chevy Z71 to an '07 Tahoe and back to a Silverado. General Motors, GM Powertrain, makes the best most solid powertrains bar none. GM has the best interiors, the best ride and they are the most reliable out there.
 
Don't listen to the GM haters out there. We really do need the domestic auto makers around. They are a large part of our Gross Domestic Product and of the Big Three at least General Motors makes a great product. GM's board just needs to replace parts of upper management including CEO Rick Wagoner possibly with Bob Lutz the "car czar" who is credited with the recent improvements at GM. Besides, what would the president do without his sweet custom armored Cadillac. Our lawmakers won't let the Big Three fail, too much of a trickle down effect. They've just been burned twice by AIG (A**holes, Ignorant and Greedy) now, so Congress just wants a solid plan. USA-1!!

hope this helps
 
You need to check fuel pressure at the rail on motor and check it at the fuel filter.
If you got good pressure at the filter suppect the the fuel pressure regulator. If
pressure the same both spots suppect fuel pump is weak.

Anyone had problems with there truck trying to start off in high gear and will not down shift or shift into overdrive. The problem is intermittent, and there is no diagnostic codes shown. Sometimes I can put back in park and shift back to drive and that fixes it momentarily.
