Extreme Ford E4OD and 4R100 Transmission Rebuild

Complete Heavy Duty Extreme E4OD / 4R100 Transmission Overhaul

Suits: Ford F150, F250, F350 and Super Duty.

The transmission is completely rebuilt including all internal wearable items such as gaskets, seals, rings, frictions, filter and pan gasket etc. We then install our recalibrated heavy duty “Nomad Valve Body Assembly”. This valve body assembly has been custom designed for our towing, touring and 4wding customers to help increase the longevity of the transmission whilst aiding in eliminating excess heat. The valve body assembly will also give you a cleaner, crisper, better quality of shift. This is achieved by increasing the lines pressures and the clamping loads to shorten the shift and allow for more direct application to the clutches. This in turn gives a more responsive crisp shift and eliminates excess wear and heat during shift. As an average from customer feedback, the valve body assembly will give you roughly 1 litre per hundred kilometres better fuel economy in normal day to day driving. This recalibrated valve body also allows for power upgrades without affecting the transmission for example chips and or exhaust systems and turbo’s.

We also supply and fit a new solenoid block, install an upgraded Heavy duty EPC Valve and use a non Pulse width modulation Lock Up Valve for additional strength, performance and reliability.

The stock standard oil pan is then replaced with a “Deep Cast Aluminium Sump” allowing for more oil capacity to keep the transmission running cooler and also stops the possibility of the transmission case twisting and causing the valves in the valve body to jam in place, causing any number of issues which is a very common problem for these transmissions.

4R100 Billet Torque Converter 400x400

Heavy Duty Double Kiln Bronzed Billet Torque Converter For E4OD And 4R100 Transmissions

The transmission is also fitted with our “Heavy Duty Double Kiln Bronzed Billet Torque Converter”. The biggest factor we need to address with these transmissions is heat reduction and the factory torque converter is well known for causing excess heat and resulting in the transmission needing to be rebuilt. Our new designed torque converter built from scratch and internal modifications enables the transmission to achieve a far greater fuel economy and keep the transmission running much cooler. Our Billet torque converter eliminates all the factory faults,  has a heavy duty spigot and is double kiln bronzed to increase overall strength and ensure the torque converter lasts the distance.
