The models above have been released with a 5-speed manual transaxle. This transaxle is used behind the 205-horsepower, supercharged and intercooled, 2.0L DOHC, 16-valve 4-cylinder engine.

The primary repair strategy for this transaxle is a complete assembly replacement. Failed transmissions will, however have the option to be repaired or replaced by the dealership.

Special service tools are available to all Chevrolet dealerships and Saturn retailers through Kent-Moore/SPX Service Solutions.

Important: 

   •  Dealers should not attempt manual transaxle unit repair without the specified special tools.
   •  Repair without these special tools is not possible.
   •  Dealers are encouraged to purchase the special tools for the MU3 manual transaxle repair.

The service strategy allows for full service of the MU3 5-speed manual transaxle only when the necessary tools have been purchased. Service procedures will be available in SI and selected internal components will be available from GMSPO.

Although special tools are available, they will not be shipped essential to the dealership. Dealerships must purchase the tools to perform MU3 manual transaxle repairs.
