Any of you guys ever come across transmission whine on startup? When I start my truck cold, I hear a distinct pump whine that sounds like something is filling up in the trans. It does this for about 4 seconds then stops. Levels are OK. It's a 2004 HD w/6.0...

In colder temps its pretty common to get a whine. I wouldnt worry unless it gets worse, or if you are near the end of your warranty.


DOH, that was supposed to read, I wouldnt worry if its been pretty cold out and it whines on first start up Censored

see if this applies.

Important
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) prior to beginning program repairs. [Not all vehicles within the above breakpoints may be involved.]


For US:
For dealers with involved vehicles, a Campaign Initiation Detail Report containing the complete Vehicle Identification Number, customer name and address data has been prepared and will be loaded to the GM DealerWorld, Recall Information website. The customer name and address data furnished will enable dealers to follow up with customers involved in this program.

For Canada & IPC
For dealers with involved vehicles, a Campaign Initiation Detail Report containing the complete Vehicle Identification Number, customer name and address data have been prepared, and is being furnished to involved dealers. Dealers that have no involved vehicles currently assigned will not receive a report with the recall bulletin.

The Campaign Initiation Detail Report may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.

Important
All 4L80E/4L85E transmissions will continue to be built using the 2nd design case. Therefore, transmissions ordered from GMSPO for installation into affected vehicles will have the same external appearance as the transmission being removed. All transmissions received from GMSPO which have the 2nd design case will have a round green paint dot on the top right of the bell housing, which indicates that the transmission in suitable for use. The green paint dot is approximately 1 in (25 mm) in diameter, and may run down the side of the case. Transmission that have the 2nd design case with this green paint dot are suitable for use in repairing a vehicle.

Service Procedure

Important
The service procedure contained in this program is different from the service procedure found in the appropriate service manual. As a result, the labor time allowance has been revised to correspond with this new service procedure. In the near future the service manual and labor time guide will be updated with this new information.


Case Inspection and Pump Repair Procedure
External Inspection of the Transmission Case Casting for Affected Vehicles
The transmission case has some external visible differences between the 1st design and the 2nd design. The differences between the 1st design and 2nd design provide for an inspection procedure to determine which transmissions will require a pump repair procedure to be performed.

Inspection Procedure
Prep the vehicle.
Raise the vehicle.
Inspect the transmission case to determine first design or second design case. The 1st design cases do not need additional service. The 2nd design cases require the Pump Repair Procedure to be performed.
Look at the transmission from under the vehicle on the passenger's side in order to determine first design or second design transmission case. The 1st design cases do not need additional service. The 2nd design cases require the Pump Repair Procedure to be performed.
Inspect the area by the cooler line quick connect fitting near the bar code label on the right side of the transmission case.
If there are two bosses, as in the left picture below, the vehicle CAN BE RELEASED FOR SALE.
If there is only one boss, as in the right picture below, then the vehicle MUST BE HELD FOR REPAIR.

Important
Do not perform the Pump Repair Procedure on 1st design cases. ALL transmission with the 2nd design case require the Pump Repair Procedure to be performed.


FIGURE 1st Design Transmission Case (Left Side) and 2nd Design Transmission Case (Right Side)(c)




Verify vehicle mileage.
For vehicles with less than twenty miles (32 km): Repair the pump utilizing the plug parts kit and Pump Repair Procedure . Remove the transmission and transmission pump using SI.
For vehicles with more than twenty miles (32 km) and no loss of functionality: Remove the transmission and inspect the transmission overdrive carrier assembly and thrust carrier/forward clutch bearing assembly and mating surfaces for heat distress or damage.
If no heat distress or damage is present: Replace the overdrive carrier assembly and thrust carrier/forward clutch bearing assembly. The Front End Play Check must be performed if the overdrive carrier assembly and thrust carrier/forward clutch bearing assembly is replaced. The Pump Repair Procedure must also be performed. Perform the Pump Repair Procedure and reassemble the transmission. Use SI to disassemble and reassemble the transmission.
If major heat distress or damage is detected in additional components, replace the transmission. Use SI to remove and install the transmission.
If the transmission has lost functionality, replace the transmission, Use SI to remove and install the transmission.
Pump Repair Procedure



Remove the cup plug from the pump cover front lube hole.



Insert the aluminum pin plug (plug kit P/N 24232339) into the front lube hole. Seat the pin flush or 1/16" below the pump cover outer diameter.



Using a chisel point tool, stake the aluminum pin in a cross pattern.



Verify that the installed plug does not protrude past the pump cover outer diameter or move under light pressure.
Floor Plan Reimbursement
Dealers in possession of vehicles included in the Stop Delivery Order dated March 12, 2004 are eligible for reimbursement of floor plan expense upon completion of the service procedure contained in this bulletin.

2004 GMC Truck GMC K Sierra - 4WD

Does not seem normal. Check fluid level to see if overfilled.

I have 4L80s in two vehicles, and they both do it occasionally. I think it is a pump cavitation noise trying to pick up fluid after sitting. I don't think its anything to worry about, however mine don't fall into the age catagory of the above article to be able to be that problem.

Spoke with One of the two tranny guys at our dealer and said not a normal noise if in park and idling. The recall most likely does not apply as if the recall hadn't been done, the tranny would burn up within 60 or so miles.
