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.

will this fit on a 2004 mach 1 automatic?


  • Thank you for your question about the Performance Automatic Street/Strip 4R70W Transmission. Unfortunately the 2004 Mach 1 with automatic transmission is AODE and this is for an automatic with 4R70W transmission.

Will this fit a 5.4?


  • The Performance Automatic Street/Strip 4R70W Transmission is manufactured and intended for use with the 4.6L Motor. This will not directly work with a 5.4L Motor without having to do a series of extensive modification.

What Torque converter is recommended for this transmission for street ability. How would that TCI that you sale do just cruising at 3000 stall?


  • The torque converter that I would recommend for this transmission is the TCI Street Fighter that is available on our site item #25304. This will work but will be a little notchy when at the 3000rpm stall.

Does this Transmission come with a one piece or two piece input shaft?I need to know if i need to buy a lock-up torque converter for the two piece or if its a one piece to buy a non-lock-up torque converter.


  • Unlike the Performance Automatic C4 Street Smart Transmission Kit (96-14 4.6L, 5.0L, 5.4L) item #62725 ( the Performance Automatic Street/Strip 4R70W Transmission (97-04 GT) will come with a two-piece input shaft. You will also need a lock-up torque converter for installation on this item.
