Attention: | DEXRON®-VI Automatic Transmission Fluid (ATF) is the only approved fluid for warranty repairs for General Motors transmissions/transaxles requiring DEXRON®-III and/or prior DEXRON® transmission fluids.

This bulletin is being revised to update model/model year information. Please discard Corporate Bulletin Number 04-07-30-037C (Section 07 -- Transmission/Transaxle).

### MANUAL TRANSMISSIONS / TRANSFER CASES and POWER STEERING

The content of this bulletin does not apply to manual transmissions or transfer cases. Any vehicle that previously required DEXRON®-III for a manual transmission or transfer case should now use P/N 88861800. This fluid is labeled Manual Transmission and Transfer Case Fluid. Power Steering Systems should now use P/N 9985010 labeled Power Steering Fluid.

Consult the Owner's Manual or Service Information (SI) for fluid recommendations.

Some of our customers and/or General Motors dealerships/Saturn Retailers may have some concerns with DEXRON®-VI and DEXRON®-III Automatic Transmission Fluid (ATF) and transmission warranty claims. DEXRON®-VI is the only approved fluid for warranty repairs for General Motors transmissions/transaxles requiring DEXRON®-III and/or prior DEXRON® transmission fluids. Please remember that the clean oil reservoirs of the J 45096 - Flushing and Flow Tester machine should be purged of DEXRON®-III and filled with DEXRON®-VI for testing, flushing or filling General Motors transmissions/transaxles.

DEXRON®-VI can be used in any proportion in past model vehicles equipped with an automatic transmission/transaxle in place of DEXRON®-III (i.e. topping off the fluid in the event of a repair or fluid change). DEXRON®-VI is also compatible with any former version of DEXRON® for use in automatic transmissions/transaxles.

### DEXRON®-VI ATF

General Motors Powertrain has upgraded to DEXRON®-VI ATF with the start of 2006 vehicle production.

Current and prior automatic transmission models that had used DEXRON®-III must now only use DEXRON®-VI.

All 2006 and future model transmissions that use DEXRON®-VI are to be serviced ONLY with DEXRON®-VI fluid.

DEXRON®-VI is an improvement over DEXRON®-III in the following areas:

DEXRON®-VI
Fluid Service Change Interval | 160,000 km (100,000 mi) For Cars and Light Duty Trucks* 80,000 km (50,000 mi) (Severe Use) For Cars and Light Duty Trucks*
Clutch Friction Stability | Improved 100%
Clutch Durability Due To Fluid | Improved 120%
Oil Film Thickness | Increased 20%
Fluid Oxidation | Improved 100%
Foam/Aeration | Improved 150%
Shear Stability | Improved 200%

* These ATF change intervals remain the same as DEXRON®-III for the time being.

### 2006-2008 Transmission Fill and Cooler Flushing

Some new applications of the 6L80 six speed transmission will require the use of the J 45096 - Flushing and Flow Tester to accomplish transmission fluid fill. It is highly recommended that the clean oil reservoir of the machine be purged of DEXRON®-III and filled with DEXRON®-VI
