1987 Fox Mustang - Return Of Ron Burgundy

Ron Burgundy has a stock 302 with unknown mileage and a Hellion 62mm Street Heat turbo kit

If you've been following along with Ron Burgundy, our '87 Fox Mustang project car, you might be wondering how the stock, zillion-mile drivetrain is putting up with 555 lb-ft of torque at the wheels from the Hellion Turbo and endless smokey donuts and street thrashing. We were wondering as well, until the transmission decided to take a few moments between shifts. After we added a set of Mickey Thompson P275/50R15 ET Street radials to get the car to hook, the stock AOD failed completely.

A quick yell across the hall to KJ Jones of 5.0 Mustang and Super Fords magazine was all the research we needed to get dialed into one of Performance Automatic's (PA) 4R70W overdrives for the car. The transmission first appeared in the '94 Mustang and is similar to the original AOD that came with the earlier 5.0L Mustangs, except that shifting and converter lockup are controlled by the computer. In addition to the overdrive, the PA transmission has a forward manual valvebody, a lockup converter, electronic overdrive control, and a transbrake.

Inside, the Fox Mustang trans has improved parts in place of any stock ones that might fail. The basics such as Raybestos clutches and high-performance bands are included, along with Ford-specific updates like a hardened stub (input) shaft and drum. The transmission has been track-tested on cars making more than 1,000 hp.
