    2007 Model Year Summary
    General Motors Powertrain-Europe F40 six-speed manual car transaxle

    ● New Detent System For Quicker And Easier Shifting
    ● Gear Ratio Changes For Quicker Acceleration


    FULL DESCRIPTIONS OF NEW OR CHANGED FEATURES

    NEW DETENT SYSTEM FOR QUICKER AND EASIER SHIFTING
    The addition of a ball-and-spring-type detent on the shift sleeve and detents on the shift rail assists the driver in shifting quicker. The detent raises the force required to move the shift lever which prevents excess movement of the shifter by the driver, and reduces the chance of double bump. Tension between the shift sleeve and the shift rail also prevents the sleeve from vibrating while in gear.

    GEAR RATIO CHANGES FOR QUICKER ACCELERATION
    To adapt the F40 to North American applications and maximize performance, 3rd through 6th gears have been changed to higher-ratio gears. The ratio for 3rd gear is now 1.37:1, and the ratio for 4th gear is no longer an overdrive, with a new ratio of 1.05:1. The 5th gear ratio is 0.85:1 and the 6th gear ratio is 0.71:1.

    LOW MAINTENANCE

    The MT2/MU9 uses a Castrol Burmah (BOT 0063) manual transmission fluid, and is validated as "fill-for-life". No maintenance is required for normal operation.

    OVERVIEW

    Originally a design developed for Fiat, Opel and Saab applications, the F40 (MT2) is a GM Powertrain - Europe six-speed manual transaxle built in Russelsheim, Germany. Its first use in a North American application was the Pontiac G6 for the 2006 model year. It is also used in some Saab 9-3 and 9-5 models.

    It is a three-axis design, with first, second, fifth, and sixth gears on an output shaft behind and below the input shaft, and third and fourth gears are on an output shaft in front of and above the input shaft. Both output shaft pinions drive a helical gear with a conventional differential. The clutch is mounted on a dual-mass flywheel to dampen vibrations on whichever output shaft is idle depending upon which gear is selected.

    The F40 is cast in aluminum, and weighs 124 pounds (see specs). It has been certified for up to 400 Nm of engine torque.

    Triple-cone synchronizers are used on 1st and 2nd gears. These synchronizers have three friction surfaces, which increase their ability to transfer the flow of torque more smoothly from one gear to another. Synchronizers act as clutches to speed up or slow down the gearsets that are being shifted to, and greater friction area results in easier shifting for the driver. The 3rd, 4th, and reverse synchronizers are double-cone, while the 5th and 6th gear synchronizers are single-cone. All of the friction surfaces on the synchronizer rings are sintered bronze. The ratios in the 6-speed are widely spaced for versatile performance and efficiency.

      And what that means folks is that a 2007 GT with the Performance Package (3900 and F40) will outperform a 2006 GTP.

        I like the gearing in the new trans a lot more than in the 06. I may have to start bitching a lot so that they give me the new one.

          Actually i dont think they will outperform the 06 GTP 3900 at all.. from what i've read they aren't even making the 3900 engine an option anymore

            Where'd you read that? It's an option on the GT now.

                    If you have a 2006 G6 GTP with the revised tranny, you probably have a slightly quicker car. The revised F40 6 MT was on GTP's built after January 1, 2006.

                      The 2006 GTP (w/ revised ratios), 2007 GT Sport (while it was made), and the 2007 3.6L GTP all seem to have virtually identical times. If you truly know how to shift though, I'm pretty sure the 6MT 3900s squeek a tenth of a second out ahead of the 3.6L automatics.

                        I just bought a 07 3900 MT, and I am not sure if I have the F40 you all are talking about... where can I look to check that?

                            Any and all 3900's with the MT option will have the F40.

                              What speed(MPH) do you usually switch into 6th? I usually wait till about 65 mph.
                              Dont BOV or your going to cause a boost spike and leak blinker fluid causing you to lock up your muffler bearings.
