is this transmission equipped with overdrive? I wanted to know if this transmission came with overdrive abd how many speeds it has is it a 5 speed?

  • 5th gear and overdrive are one and the same. So it is 4 speed with overdrive.

    What a headache

    I bought one with the matching torque converter. Poor clumsy shifting, faulty solenoid pack. TCI sent me a replacement pack, now I have even more error codes. What a waste of money. TCI is no leader in quality auto parts. Save your money.

    Great upgrade

    Bought this after I tore up my stock transmission in my 2010 GT. Runs really smooth and is awesome paired up with my TCI StreetFighter Torque Converter. Price is higher now than when I purchased it, and it should be noted that this item doesn't ship from American Muscle and took longer than was advertised when I ordered it.
