i made it over from GAOC to see how you all were doing here, and noticed that alot of you are having 2-3 shift problems..
well i work at a chevy dealer, and have access to service info.. and decided to check for you all about the bullitins...
when you are talking to service writers, they dont usually check for anything, and to tell you the truth, neither do half the mechanics.. well the ones that think they are the best and dont need help.. i on the other hand am the guy who will take even more time than needed and check through SI.
well heres one about the echange program:
THIS IS FOR THE F40 only right here. VVV

Opel F40 6-Speed Manual Transaxle/Transmission Exchange Program (RPO MT2) #06-07-29-002 - (Feb 3, 2006)
Opel F40 6-Speed Manual Transaxle/Transmission Exchange Program (RPO MT2)
2006 Pontiac G6
with Transmission - Man 6 Spd, Opel, 83 mm, 3.77 1st, 0.62 6th (F40 WR) (RPO MT2)
This bulletin will cover the F40 6-Speed Manual Transaxle exchange program for the 2006 Pontiac G6. This exchange program will be in effect for approximately the first 12 months of vehicle production.
This exchange program will be administered by the GM Product Quality Center (PQC). To request an exchange, dealerships are required to call the PQC - not the Technical Assistance Center (TAC). The PQC may refer the dealer technician to TAC if additional diagnosis is required. Prior to calling the PQC, please make sure to complete the "OEM Manual Transmission Exchange Worksheet" referenced at the end of this bulletin. Use of this worksheet will minimize the time spent on the telephone and avoid the need of a second call to the PQC. Guidelines for honoring exchange requests under this program are being strictly enforced.
Components that may be removed and serviced without exchange of the transaxle are identified in the list below. Any repairs involving transmission components not identified in the table below may require a transmission exchange.
Please note that this list is subject to change as the program progresses. You will be notified by the PQC consultant if additional transaxle items are considered serviceable.
Current Serviceable Transaxle Related Components:
• Seal, Drive Axle
• Sensor, Vehicle Speed
• Switch, Back Up Lamp
• Pin, Clutch Housing Lock
• Plug, Trans Oil Drain
• Bolt, Vehicle Speed Sensor (VSS)
• Bolt, Vehicle Speed Sensor (VSS)
• Actuator, Clutch Asm
• Plug, Trans Fluid Fill
• Control, Shifter Assembly
All other components of the transmission require assembly replacement at this time.
Important: Transmission repairs or failures that are caused by components external to the transmission DO NOT fall under the exchange program. For example, transmission oil cooler lines incorrectly installed causing a transmission failure will have to go through GMSPO to obtain a transmission assembly. Also, transmissions needed for insurance repairs have to be obtained from GMSPO. The exchange program is created as a way to identify and correct internal concerns. External components causing a failure do not provide any useful information in improving a transmission. The transmission received from GMSPO will be a new transmission. As normal process, all warranty claims for transmission replacement must be approved through the PQC.
A thorough diagnosis must be performed in order to prevent unnecessary component replacements. Refer to "Diagnostic System Check - Vehicle" in SI to identify the correct procedure for diagnosing the system.
Prior to calling the PQC, complete the "OEM Transmission Exchange" worksheet referenced at the end of this bulletin
Contact the PQC to verify that proper diagnosis has been performed. Upon review of the diagnosis, the PQC will establish a case reference number and make arrangements for shipping an exchange unit to your dealership if necessary. DO NOT SHIP A TRANSMISSION TO THE WARRANTY PARTS CENTER (WPC) WITHOUT AN OFFICIAL WPC REQUEST.
Important: Failure to return the replaced transmission by the due date will result in the dealership being debited the entire warranty claim (parts and labor). The removed unit must be returned complete in the shipping container. For effective engineering analysis, please do not remove or disassemble any components. The only exception to this is the fluid pan, which should be removed to drain the fluid prior to shipping. The pan must be reinstalled after fluid has drained. Dealerships returning transmissions that have been even partially disassembled will be judged as violating this procedure and, as such, will be billed for all materials furnished.
For vehicles repaired under warranty, use:

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

-The transaxle uses a Castrol BOT 0063 (P/N 21018899) transaxle fluid that allows proper synchronizer operation. The incorrect fluid may cause hard shifting by varnish build-up, or not enough lubrication for proper synchronizer operation.
