I cant figure out what this noise is i accelerate to 40 mph then let off the gas and around 35 mph it happens for a couple seconds only happens when the car is in gear sounds like it could be front diff or input shaft bearing i could use some help!!!!!

The soundtrack was also processed with volume normalization, noise
reduction, clipping reduction, and equalization (the resulting sound,
though not perfect, is far less noisy than the original).
A machine consists of a power source and a power transmission system, which
provides controlled application of the power. Merriam-Webster defines
transmission as: an assembly of parts including the speed-changing gears
and the propeller shaft by which the power is transmitted from an engine to
a live axle. Often transmission refers simply to the gearbox that uses
gears and gear trains to provide speed and torque conversions from a
rotating power source to another device...
Manual transmission come in two basic types:
- a simple but rugged sliding-mesh or unsynchronized / non-synchronous
system, where straight-cut spur gear sets are spinning freely, and must be
synchronized by the operator matching engine revs to road speed, to avoid
noisy and damaging "gear clash",
- and the now common constant-mesh gearboxes which can include
non-synchronised, or synchronized / synchromesh systems, where typically
diagonal cut helical (or sometimes either straight-cut, or double-helical)
gear sets are constantly "meshed" together, and a dog clutch is used for
changing gears. On synchromesh boxes, friction cones or "synchro-rings" are
used in addition to the dog clutch to closely match the rotational speeds
of the two sides of the (declutched) transmission before making a full
4L60E Transmission Teardown Inspection - Transmission Repair
On this video we can see the disassembly of a 2006 4L60E transmission. The
most common failure on these units is 3rd. clutch burn up, the reaction sun
shell and the 2-4 band. Failure on these transmissions is not necessary the
way it is treated, rather is these common or pattern failures. Valve body
ware is also another issue and can be corrected installing a correction kit
of your choice.
The D-Drive Infinitely Variable Geared Transmission
This brain-bending invention could be the holy grail of transmission
technology - it allows you to smoothly move through gear ratios from top gear all
the way through neutral and into reverse without ever disengaging the
engine. Plus, there's no friction drive component, so the power is always
transmitted through gear teeth - there's never any slip or friction losses.
In fact, the D-Drive's main difficulty is that it's so damn hard to
understand that people don't really know what to do with it. So here's a
close-up look, which will hopefully get a few people thinking.

Noisy Transmission Bearings
Bad Transmission Bearings-Transmission whines and makes excessive noise.
This is the 6th transmission in this car.
Transmission whining/grinding noise on a 97 740iL
UPDATE: Resolved the issue in June 2012 by performing a transmission fluid
change, replacing the Febi filter the shop installed with a Genuine BMW
Filtran filter. No noises at all in the last two months.
Whining noise my 740iL makes when accelerating with a cold engine.

Honda Transmission Rebuild Video - Transmission Repair
On this video we see what it takes to Rebuild a Honda Transmission, what
parts it takes and what has been working to correct some of the common
failures on these transmissions.
Blue Overheated Torque Converters has been a common issue on these
Transmissions for a long time and we still see this regularly to this day.
Although there are various shift correction kits and special valves out
there, all work really good on correcting the issue with the lack of
converter feed fluid. I like them all. So if a deciding factor is important
to you on which method to use, all I can say is this, They all work.
Keep in mind that there are "other" fixes or items that can be added to the
rebuild, but it is not really necessary if they're not really needed, I'm
not mentioning any but I know some of you will.
With that being said I like to thank you for watching this video and liking
it and sharing it.

2004 Civic Manual Transmission Noise
Horrible noise coming from my '04 Civic LX's manual transmission. Noise has
been getting worse; started at 100k miles, and here we are almost 30k
later. Any ideas?

350z Rubbing Vibration Noise when Accelerating
Strange noise from 350z when accelerating... The beggining you can hear it
well but when I put the camera on the dash it's very noticable.. You can
hear the normal engine accelerating noise in the background and the hollow
type strange noise over it all. Feels like it takes a performance hit too.

2007 Chevrolet Silverado Clunk Noise Fix
I have had this Silverado for about a year and it has always had a clunking
noise when shifting from neutral to drive, when starting from a stop, when
shifting from 1st to 2nd, and when hitting bumps in the road. I took it to
the dealer where they diagnosed and charged me $200 to "Lube and Service
Splines" on the input shaft. I also replaced the universal joints in the
drive shaft. These fixes did nothing to change the sound. I just drove the
truck extremely mild to minimize the embarrassing noise coming from this
nice truck. There are some other noises on forums I've read that are more
than likely transmission, spline, or rear end issues. I just wanted to post
this because it was definitely my problem and at least it could be
something to check.
