Question about 2003 Chevrolet Silverado 2500HD

Noise in transmission

I just bought a 2003 Chevy silverado 2500. It is a great truck and the engine runs strong and the truck drives out great. I had two mechanics look at it and both gave it good reports.

However, when I picked it up it made a whistling noise from the drive train. It shifts fine, accelerates a little slow in first gear. As soon as it shifts out of first (in drive), the noise goes away. I took it to another mechanic and asked him about it specifically and he said it is just a trait of the particular tranny.

Should it be something I need to look into or go with the ol phrase it aint broke don't fix it?

I always say, if you can't find it to fix it, let it deveope into something you can.. Have your trans ofluid and flter changed and inspected. I love my o3 1500. The 2500 I expect would be a little stouter. Good Luck

I have a 2003 Yukon XL 2wheel drive with a 4L60E transmission and a 5.3 engine will this transmission work in my 2009 chevy Silverado with a 4L60E transmission and 5.3 engine

What you actually have is a 4L65E Transmission, and the 09 version of that transmission is the 4L70E. Luckily it is not hard to turn your 4L65E into a 4L70E. You will have to change your speed sensor and if you want it to be as strong as the 4L70E you can upgrade the output shaft. Either way you can use it for that vehicle as they are the same bolt pattern. Just dont do too many performance upgrades. Hope this helps

2003 chevy silverado is cranking and running but will not accelerate.

Need codes, because the engine and transmission will both cause "reduced power".

Clanking noise coming from Allison Transmission on a 2001 Chrevrolet Silverado 8.1 Liter engine

this does sound like theres a loose line tapping the engine/frame,during warm up the engine idles faster which could make it vibrate faster causing the the clanking or tapping noise,if this has started after trans fluid change,then check the lines running from the trani to radiator sometimes the service person might bang into something causing plastic clips that hold the lines to break,try getting under it and have someone start the truck and listen to see where it's coming from also hold the lines & see if the noise stops,the service guy could have unbolted something & never put the bolt back causing the clank ex.line may have a clip holding it thats bolted to the trani pan ?good luck

Remove the auxillary drive belts and run the engine without them .If the noise is gone then its something driven by the auxillary belts.if not then check timing belt runners [if fitted]But check oil -water levels first

2003 chevy silverado 2500 HD when ingageing 4 wheel high on the fly it makes a load clunk and grinding noise

I had a similar problem and had to have the 4 wheel drive serviced. It need new grease. the grease i had was old and it was causing the gears not engage cleanly thus causing the grinding sound until they were realigned.
