    500 HP Rated. Is your modded Mustang in need of a heavy duty automatic transmission that can handle the power you want to add? Then you need to upgrade to the Performance Automatic Street/Strip 4R70W Transmission. This 4R70W Street/Strip Transmission is the perfect replacement upgrade for your old automatic and is capable of handling up to 500 horsepower, making it ideal for high-performance applications.

    Built Better than Ford Tough. The Performance Automatic modified 4R70W Transmission is equipped with heavy duty clutches and servo, high performance bands and a new steel pan, in addition to the street/strip valve body. With the tweaks made by Performance Automatic, your Mustang GT will have crisp shifts, improved thrust capacities and endure a longer life.

    Application. The Performance Automatic 4R70W Automatic Transmission is specifically designed for use in the 1997 to 2004 GT Mustangs that came with the 4R70W transmission.

    Please Note. In 1997, Ford changed their transmission from AODE to the 4R70W. To ensure which transmission came in your GT, you will need to check your tail shaft housing. If you have a "W" cast into the housing, you have the 4R70W transmission. If you do not, you have the AODE transmission.

    Note. This Transmission does not include a torque converter.

        I’m trying to decide if I want to upgrade the transmission on my 2001 GT or not. How much power can the stock 4-speed transmission handle. I would like to be somewhere just north of 320 horsepower to the wheels.

        • The Stock 4R70W can easily handle 320hp to the wheels typically holding up to 400-420hp without issue, however we would recommend adding a transmission cooler to increase longevity of the transmission as heat is what typically kills these transmissions.

        Hello I'm wondering why this auto trans only fits a GT? My 99 3.8 V6 came from the factory with a 4R70W. Am I missing something here? Any help would be much appreciated. Thank you.

        • The Performance Automatic Street/Strip 4R70W Transmission has a modular bellhousing, which will not work with a 3.8L as it utilizes the old windsor bellhousing bolt pattern.

        What type of transmission fluid do you recommend for this transmission?

        • The Performance Automatic Street/Strip 4R70W Transmission should be filled with a synthetic Mercon ATF.

        Do you have to purchase a torque converter if you purchase the Performance automatic transmission 4R70W? If not, would it be important to purchase the TCI street fighter anyway in regards to regular operation and performance of the new transmission?

        • The Performance Automatic Street/Strip 4R70W Transmission can be used with the stock converter, however it is strongly recommended to use an aftermarket high stall torque converter.
