Whines in neutral with clutch out and while driving in 4 of 5 gea

A common cause of a whining or buzzing type noise when not in gear (neutral and park) is a WORN PUMP in the transmission. How many miles are on the car??

A noisy pump is just noisy and won't cause a breakdown until it becomes MUCH louder. If the noise is not that loud at this point, just keep driving it for now, and chalk it up to normal wear & tear. But DOOO make sure your transmission fluid is topped off. The amount of fluid between the LOW and FULL marks is about one pint. DON'T overfill OR allow it to get below the LOW mark. Transmissions are VERY fluid-level-sensitive.

possible cause is the torque converter clutch servo/solenoid
changing on the indicator but no drive through the gear box
run the fault codes and check for problem clutch servo/ solenoid or transmission control module
check all wiring and connections to transmission

If it's not whining when you have your foot on the clutch and are stopped, its not the throwout bearing. While driving the throwout bearing isn't being used....
Transmission whine is either in the transmission or differential.

The transmission fluid filter is the problem. This service should have been done at 80,000 miles. A dirty filter will cause the charge pump whine and loss of charge pump pressure will cause clutch packs to slip. Do not perform this service yourself, Its messy and not for novices. Do not drive or damage to clutch pack friction plates will occur.

Time for a rebuild or a new tranny, this one won't last much longer, sounds like there are bearings and clutches failing or failed already.

Some owners of the above models equipped with a Hydra-Matic 4T65-E transaxle with a Julian Date prior to 0045 may comment on a whine noise in PARK and/or NEUTRAL or a Service Engine Soon or Service Vehicle Soon lamp that is illuminated. Upon investigation, a DTC P0741 or P0742 may be found.

Cause:
The above condition may be due to drive sprocket support bearing fluting and/or bearing failure.

Correction:
Replace the drive sprocket support bearing. Inspect the channel plate and drive sprocket for any abnormal wear, Turbine shaft for cut seals and/or nicks, and chain for excessive play due to failed bearings.

Important:
When installing the new bearing, the part number MUST be visible (facing upward). Before installing the drive sprocket, lubricate the bearing assembly with J 36850 assembly lubricant.

Refer to the 4T65-E Unit Repair Section for the installation procedure.

Its possible that you can use a voltmeter to test for power and ground at the TCC solenoid connector and also resistance across the solenoid. The scan tool is helpful in pulling the codes, commanding the TCC on and off and monitoring the state of command while driving.

Hope help with this (remem,ber comment and rated this).

If the truck was ran low on fluid to the point it clangs and bangs, the internal damage is done.
The best you can hope for is burnt bearings and hopefully the shafts are not scored. Disassembly is the only solution. Or a used transmission.

SOUND LIKE TRANSMISSION IS SLIPPING.CHECK THE TRANSMISSION FLUID MAKE SURE ITS NOT LOW.ALSO IF TRANSMISSION FLUID LOOKS DIRTY DARK AND SMELLS BAD REPLACE FLUID AND FILTER.IF FLUID IS GOOD YOU HAVE.TRANSMISSION OIL PUMP AND FORWARD CLUTCH PROBLEMS.

linkage broke or clutch cable

Run the car from the top of a hill and let it coast at your whining speed. Put it in Neutral, does the whine disappear?
If not its in the drivetrain (wheels, driveshafts, tranny)
Very unlikely to be the timing belt. If it appears at a fixed speed then its drivetrain, if it whines at fixed revs its the engine.
Most likey the transmission I fear....Tires will also make loud whining noise too though...
