Product Description

Street Smart 4R70W Package
Upgrade your 1979-1995 Mustang 5.0/5.8 driveline with this Performance Automatic 4R70W Street/Strip transmission kit. The factory automatic transmission offered in 1979-1995 Mustangs was not originally designed with performance in mind and was plagued with sloppy shifts and poor reliability. Performance Automatic solved this problem with this Mustang 4R70W transmission that handles the high horsepower and torque from your 5.0/5.8L motor. This automatic transmission includes a street/strip valve body that gets your Mustang shifting and driving better than ever. This transmission also features heavy duty clutches, high performance bands, a new steel oil pan to hold up to 550HP. This transmission is machined to bolt directly to your 302/351 motor.

2400-2800 Stall Torque Converter
The 12" 2400-2800 RPM stall converter included in this kit is designed to work directly with your new 4R70W transmission. The 2400-2800 RPM Stall is great for Mustang's that see a mix of street and strip driving.

Performance Automatic Quality
Along with the new transmission and torque converter, this kit includes a new steel pan, neutral safety switch, drum & diode. The clutches inside are heavy duty Raybestos brand. For added performance there is a large overdrive servo, hardened stub shaft and hi-performance band. This kit has an included smart shift controller that works with both electronic and mechanical speedometers.

-Requires a 164 tooth flexplate. Not included.

-Fits 1979-1995 Mustang 5.0/5.8
