Absolutey! The Duramax/Allison auto has no problems hauling the load in overdrive. It will not be put in drive and ran early redline at 75mph to pull a fairly light trailer. IMO, the idea of not letting the tranny shift to OD would be used on a vehicle that is underpowered/not enough tranny strength for the job. This truck is built for this job. It never down shifted to drive b/c it had plenty of power. Power and/or gear selection isn't the problem. The cruise is just too lazy when pulling trailers............

I hate to see that happen but I can't say as I blame anyone for jumping over, the way you get treated with some of these dealers is what will kill the big 3.

The radios have a security lock in them that is programed to each individual vehicle. I changed from one style to a different one, (both factory models) and had the dealer program it for my truck's code and it works fine. I don't see why they can't just give you a new radio and set it up for your truck.

Thumping noise is the intermediate steering shaft. Take it in and make them put a new one in. My 04HD has made a whine-hydraulic flow type noise since it was new. Not sure that it's the same thing you're talkin' 'bout. I'm not too concerned with it, I figured that was a characteristic of this tranny. (4l80E ?)

Re: Electric seats [tenga] by tenga

Just in case someone has the same problem with the electric seats, I found out what the reason why the seat wouldn't move.
There are two cable that run from the both sides of the seat, to a electric motor in the middle. If you put your hand under the seat, they are about 5-6 inches from the front edge. The main drive motor, turns the two cables, which drive the rail sprockets, that move the chair forward or backwards.
These cables (speedometer type), are about 6 to 7 inches. Here is what I had planned to do; 1/ go to the dealership and order (2) two of the speedometer type cables; 2/ Install them both myself; 3/ Be happy as a lark.
No! No! No! It doesn't work like that. Remember vehicle designer don't design things, to make it easy on the mechanic (or you), and your wallet.
Those two (2) 6 to 7 inch cables, will cost me close to $400. BECAUSE you have to buy the whole under-carriage.
They haven't got my money yet. Hopefully, I can locate the cables through a parts place, junkyard or from a place that makes speedometer cable.
Anyway, I hope this helps someone down the line. I'll keep the forum informed, on the results.

Anti freeze by mailman2
Nov 16, 2005 (8:01 pm)
Just changed the anti freeze on my 01 Sierra Z-71. A mechanic friend told me to drive up to temp. then drain it, fill with water then drive it, drain again, fill with water, drive and drain. The last drain was just a shade pink. No gunk at all. Filled it with a 50/50 mix dex cool [distilled water]. good to go. 37,000 miles Total cost $13.00 and 2 hours waiting

I have a 99 1500 sierra with the 5.3L, I have experienced this every year for the last 3 year, whenever it gets below 20 degrees the engine refuses to idle, it drives perfectly perfect, I do not have this issue from spring to fall, only when it dips below 20. the code produced was a P0171 & P0174, I had the dealer replaced the air flow sensor but that didn’t work, then they said to replace the fuel tank? What? This is a problem below 20 and I am going to buy a new tank and fuel pump? This makes no sense. These are the same people who told me my heater blower was fried and to buy a new one 350.00 when all I needed was the 35 dollar resistor, I was also told I needed a complete transfer care repair for my 4 wheel drive service light when all I needed to do is replace the auto switch control on the dash. Any help would be much appreciated

03 hd fuel filter problem by nofearmx
Nov 17, 2005 (1:20 pm)
I have a 2003 2500 hd duramax diesel and i keep having to change the fuel filter. The problem is the truck sometimes takes a little longer to start and once it does it runs great like the day i bought it and their is no problem. Then other times it will not start. I had it looked at and they found out it was the fuel filter the first time. Well the problem seems to just keep repeating its self in the worst situations; like in the morning before work, out in the woods, and at job sites. It has happened 6 times. I keep a spare filter in my truck and an oil filter wrench. I thought it might be bad gas but it has happened so many times in lenghty time periods where I fill up at differnt stations. This is getting way to expensive and I do not know what to do next. Any help or suggestions would be greatly appreciated. Thank You
