    Automatic Transmission

    Hey Guys,
    I was wondering if anyone knew of an automatic transmission that is a direct bolt in or one that someone sells a high quality conversion kit that would mount to the stock fiero 2.8. I am looking at a car that I would need to replace the transmission and was wondering if there was a simple way to upgrade to a 4 speed. I know GM made a auto four speed that was decent from 87-90 but was not able to find a simple conversion kit. Thanks Fellows

    I've got a 4T60E from a 94 Cutlass in my wife's Fiero. Of course it has the 3100SFi engine as well, but I think it bolts up to the 2.8. The older versions of the 4T60 are not electronically controlled so you should be able to use it without swapping the ECM. I love driving her car! About 2300 rpms at 90mph and smooth as silk!

    Sorry to hear that... What kind of car were you looking at? Maybe some of us can help you find a replacement.

    Don't know of a trans right off hand but I can tell you that if you find a 4 speed auto that bolts up to a 2.8L or a 3.1L that is in the 90's style cars, and then use the Rodney Dickmen kit to change the mounts to a Fiero mounted trans. In the 80's the top speed limit was 55 on all high ways, now its 65 or 70 in some states so a 4 speed has been added for extra fuel mileage. That way be a god route to go?
