    Fiero transmission?

    I am going to buy fiero from Germany and now I have to decide what kind of transmission should I have in my next car. They are selling some 4-speed manual transmission and also some 4-speed automatic.

    I want to change my gears myself so the manual should be great for me but I also wonder if there is some kits for automatics that allow me to change gears myself. Does anyone know where I can purchase these kits and how much they might cost? Are these kits really working as semiautomatics because thatīs what I want most.

    What is the code of Fiero transmission? Is it th-125 or 4L60?

    Stock Fiero automatic transmission is a TH125, it's a 3spd. 4L60 (4spd) is from newer GM front drive cars and will fit. Not sure if it is a direct bolt in though.

    To shift yourself in an auto get a ratchet style aftermarket racing shifter, and a shift kit in the tranny. You can get teh shifter at - not sure where to get a shift kit though.

    No. 4L60 (TH700R4) is front engine rear drive. the 'L' designates longitudinal. The 4T60 is the first gen transverse 4 speed auto that was used in front drive cars until about 1990 in most models.
