FORD SMALL BLOCK TO GM AUTOMATIC TRANSMISSION ADAPTER KIT | PAFO102

Ford 289 / 300 / 302 / 351W / 351C to GM TH350 / TH400 / 700R4 / 4L80E

The PAFO102 adapter kit gives Ford Small Block owners the ability to run popular GM automatic transmissions behind their Ford engine.

This opens up an entirely different range of drivetrain options for classic Fords, hot rods, custom builds, off-road vehicles, restomods and performance applications.

Buy the adapter kit by itself or let Twisted Torque help build the complete transmission conversion package around your vehicle, engine, horsepower and intended use.

BOLT-ON FORD TO GM TRANSMISSION CONVERSION

The PAFO102 uses a precision-machined billet aluminum adapter plate to properly mate the supported Ford engine to the GM automatic transmission.

The conversion retains the complete GM transmission bellhousing, so cutting the transmission bellhousing is not required for the standard supported applications.

The included flexplate, crank spacer, converter adapter, starter and installation hardware provide the major components required to properly mate the two drivetrain platforms.

BUILD A COMPLETE TWISTED TORQUE CONVERSION PACKAGE

Already know you want to make the jump from a Ford transmission to a GM automatic?

We can take it further.

Twisted Torque offers complete transmission conversion packages built around the vehicle, engine, horsepower and intended use.

PAIR PAFO102 WITH A TWISTED TORQUE 700R4

The 700R4 is an excellent option for customers looking to add automatic overdrive to a classic Ford or custom build.

Available Twisted Torque 700R4 packages include:

• Twisted Street™ 700R4

• Twisted Pro™ 700R4

• Twisted Punisher™ 700R4

Depending on the package and application, our 700R4 conversion systems can include the built transmission, torque converter, TV cable and geometry components, lockup wiring, transmission mount, dipstick and tube, cooler, cooler flush and other installation components.

PAIR PAFO102 WITH A TWISTED TORQUE 4L80E

Need more strength or building a higher-horsepower combination?

The electronically controlled 4L80E gives Ford Small Block builders another serious overdrive option.

Twisted Torque offers multiple 4L80E performance levels, including Street, Pro and Punisher configurations for applications ranging from street-driven builds to high-horsepower, towing and aggressive performance combinations.

A 4L80E installation behind a traditional Ford engine will require proper standalone electronic transmission control. Controller and wiring requirements depend on the exact engine, vehicle and transmission combination.

TH350 AND TH400 COMBINATIONS

PAFO102 can also be used to put a TH350 or TH400 behind the supported Ford engines.

These are excellent options for customers who want a strong, straightforward non-overdrive GM automatic without the electronic control requirements of a 4L80E.

Talk to Twisted Torque about the vehicle, horsepower and intended use and we can help determine which transmission and build level makes the most sense.

IMPORTANT 4L60 / 4L60E FITMENT NOTICE

Do not assume every 4L60 or 4L60E transmission is compatible with this adapter.

Compatibility depends on the specific transmission and torque converter configuration, including differences between early 298mm and later 300mm applications.

If you are considering a 4L60 or 4L60E, contact Twisted Torque before ordering so we can verify the transmission and converter combination.
