'09 Whine


Recommended Posts

Posted

I have an '09 5.3 w/6sp and my truck makes what a think is a whine that's most noticeable taking off in first gear and then after the shift to second I don't notice it that much. It is very obvious when using the blue tooth while talking on the phone through my speaker system. Took it to the dealer and they said it was typical of that transmission and was the planetary gear whine. I have only ridden in one other 5.3 six speed and it was a tahoe and it didn't do that or I couldn't here it. What do you guys think?

I'm sorry, I only have the 4 speed. But, I do know it is typical for some 4 speeds to make that whine, it'll still last just as long. It could also be a power steering pump. As long as tranny fluid is bright red, full, and not foaming, it'll be fine.

09 no whine. I assume you are not hear the sound coming thru speakers??? Probably not an issue and you documented at the dealer so enjoy.

Hi Brandon:

I know nothing about the newer 6spd.'s. - - - but I have learned a lot about a Loud Whine in the 4L80e four speed A/T's within these past 4 months.

 

Some of the 4L80e transmissions do exhibit a quite "whine" in 1st gear. You can only hear it with the radio/stereo OFF and the drivers side window down. This is due to a stronger straight cut 1st gear in these heavy duty A/T's.

 

If the whine is LOUD - something is NOT RIGHT. Mine was so loud that people stopped to stare as the truck started from a stop. It was even worse if there were cars beside me in traffic - the sound would be amplified bouncing off them.

 

Take it to your Dealer and complain. NO NEW TRUCK should have a WHINE in 1st Gear. Get it clearly documented on the Service Forms... write it up yourself on the form - if the Service Writer doesn't describe it correctly . ie Unacceptably LOUD WHINE IN 1st GEAR.

 

Do not accept the explanation that it is "normal" - ask them to show you two other trucks on the lot that make that noise, tell them you didn't pay $30K to $40K for noise transmission. If they don't fix it - Contact GM/Chevy Customer Assistance.

 

I just went though this with my 2005 2500HD - with less than 36K miles. Thank goodness the original owner complained about it starting at 16K miles in 2007. GM/Chevy just replaced the transmission at no charge. Both my Service Manager and GM/Customer Assistance were helpful in resolving the issue.

Scroll down to my first Post - then follow along..

 

you might want to see if there is a 2009 Problems thread on Facebook - and Post your problem there.

 

Read The Original Service Bulletin for the 2004+ 4L80e here

This does not apply to your 6spd - but there may well be a newer Service Bulletin that does.

 

good luck,

after reading and posting I was listening to the truck a little more. I do hear it a bit in first gear. Now just how loud yours is would be the factor to determine if it s normal.

My brother and I went to a gun show today and I wanted to see if he noticed it and he didn't. It really is not loud it's just there and I can sometimes be ultra sensative about things with my truck. The dealer has been made aware and it's documented. I'm just gonna let it go unless it gets louder. I know I have a 100,000 mile power train warranty I just like to catch things early regardless of who is paying for it. Thanks everyone for your responses.

    • I like the idea.  I would pick diesel if I had a choice. I need pictures though.
    • I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

    • You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode. 
    • "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
